Wastewater Detailed Services

  • Cleaning and Removal of Sludge and Debris (manholes, septic system and lift stations)

We use extended scoops and clamps to remove scum and other debris from underground septic tanks, absorption pits, latrines, lift stations, manholes and other confined spaces.

A manhole, inspection chamber or access chamber is the top opening to an underground utility vault used as an access point for performing maintenance to sewers and storm drains, for the cleaning and removal of sludge, dirt, sand, rocks, grease, and other solids or semisolid material from time to time.Lift stations are low points in a gravity-flow sewer system where incoming sewage is pumped from a well to a higher grade to continue the gravity flow to the treatment plant.   As solid material, such as rags, stones, pieces of wood, metal, etc. enter the lift station, buildup will occur on the bottom of the well and in other components within the lift station.   Solid materials can often plug or damage pump impellers, so periodic cleaning is required to remove the solid material from the lift station.

Before septic tanks were common, sewage from dwellings was oftentimes disposed of in covered up perpendicular pits called cesspools.  It is not rare to hear a seepage pit called a cesspool, or the other way around.  Yet, seepage pits and cesspools are two different things.  They’re alike in structure but serve dissimilar functions.  A seepage pit is utilized for disposal of clarified wastewater from a septic tank, whereas a cesspool is both tank (collection and holding of solids) and drainfield (the latter being the soil around the cesspool to receive the liquid).

The cesspool was an early adaptation of the current-day septic system, offering a belowground arrangement for disposal of waterborne sewage.  Usage of cesspools was primarily driven by conve­nience and their positioning governed chiefly by the closest usable land.  In fact, cesspools were even constructed in the basements of urban buildings.  This is in obvious contrast to current septic system designs, based on soil and groundwater conditions, and intended for long-term use. In most regions, cesspools are banned by local health and building codes.  Accordingly, new construction of cesspools is relatively uncommon, nevertheless, numerous cesspools are still in active use.

A typical stone walled cesspool is a cylindrical hole in deep soil, several feet in diameter.  The side is packed with stones about 10 to 12 inches in diameter; this is to prevent the sides from collapsing.  There is a concrete decking spanning just beyond the diameter of the stone wall with a lid riser and a manway access port secured with a lid.  Raw wastewater flows into the stoned packed cesspool, where partially digested solids remain and the effluent seeps through the bottom of the cesspool and through the weep holes in the stone wall then into the surrounding soil.

A seepage pit is, in essence, a upright leach or drain field, consisting of a deep hole with a porous-walled inside chamber and a filling by gravel between the chamber and the encompassing soil. Seepage pits are typically 4 to 12 feet in diameter and 10 to 40 feet deep. Septic tank wastewater enters the inside chamber and is temporarily stored in that location until it gradually seeps away and passes through into the surrounding sidewall soil.

The wall, along with the surrounding gravel fill­ing, provides structural support for the pit.  The wall is 1 to 2 feet smaller in diameter than the actual pit, and may be constructed of pre-cast concrete rings or a cylindrical wall of brick or concrete block. For outward seepage of the effluent, concrete rings have pre-cut holes or notches; bricks or blocks are laid up with staggered joints.  In a smaller diameter cavity, the interior chamber may consist of a large-diameter perforated pipe placing upright .

A typical brick or block walled cesspool.  As with drain field and leaching field trenches, seepage pits go through progressive biomat growth.  Because the biomat grows thicker in the lower level, the effluent climbs to a higher level, where it permeates through the unclogged sections of the sidewall.

Because the biomat is comprises of living anaerobic bacteria microbes that grow only in the absence oxygen, its balance can be upset.  Septic tank troubles can result in an excess of solid waste matter (nutrient) to the biomat organisms, stimulating excessive growth and, consequently, cutting back the ability of the sewer water from the septic tank to pass through the biomat and go into the soil.  In the supersaturated state the dirt’s aerobic qualities no longer exist, and controlled breakup of the biomat by aerobic soil bacteria will no longer take place.

Cross section of a failing seepage pit/cesspool caused by septic tank problems.  The biomat has gotten too dense and impenetrable, and the wastewater sent to the seepage pit / cesspool will rapidly and easily exceed the amount that can filter out through the biomat.  The consequence is backflow into the septic tank (and possibly also into the house), and surfacing of effluent above ground over the seepage pit / cesspool or septic tank causing wet spots and rapid grass growth, in other words “a failing septic system.”

Confined spaces are those areas which are not intended for continual human occupancy with limited means of egress and have the potential for physical, chemical or atmospheric engulfment.  In these spaces we work very close to hazards, where proper guarding may not exist to prevent falls and the air may be toxic or explosive.  In addition, such an area may not have easy way to exit should an emergency arise.

All Team members receives in-house technical rescue training as a team to practice and hone their skills utilizing our teams equipment and resources periodically.  Additionally, all members receive extensive on-going training in other critical areas to ensure their safety and regulatory compliance while working in an industrial environment.  Our company has the ability to provide intrinsically-safe fans and blowers, confined space attendants and supervisors for your projects and needs.

  • Consultancy (professional advice)  

Finding the right people with the appropriate qualifications and experience is an extremely difficult but important task.  WAYMAH offers a wide range of technical and consultancy solutions for water and wastewater treatment, pumping, distribution, repairs, maintenance and construction applications.

We offer knowledgeable and practical water and wastewater consulting services that add real value to our customers providing real benefits; no matter how large or small being government agencies, private sector or home owners.

Buying a property is a major investment, therefore determining the location, working-ability and the appropriate design of the water and wastewater system is important.  We are able to carry out a site inspection to go through and advise on the water and wastewater system as they exist, their adequacy and recommend any improvement that may be required.

            Services Provided

  • Site inspection
  • Feasibility study
  • Preliminary design report and budget estimate
  • Detailed planning
  • Working drawings
  • Specifications
  • Periodic site supervision
  • Attend site meeting
  • Testing and commissioning participation
  • Design and Installation/Construction (septic system, grease trap, drainage, wastewater treatment plant, gray and black water separation)

Every day there are several water and wastewater system being designed and constructed.  May systems appear to be fine upon commissioning, however, many instances there are major failures that show up within the first 2 years of operation.  Water and wastewater are two basic necessities for every property, therefore, their design, installation and/ construction should be optimum.  It is always more cost effective to have it done the right way the first time than paying a higher price to have corrective works carried out.  WAYMAH design, construct and install various water and wastewater systems to include gray water reuse for government agencies, private sector and home owners.

Dewatering systems are routinely used in the construction industry to provide temporary lowering/reductions in ground water levels for structures which extend to below groundwater level.   A dewatering pump is used to continuously pump to lower the water table to provide stable and dry conditions to facilitate excavation, installation and or repairs to concrete structures, pipeline, pumps, valves, or for rescue operation.

Our 8 inch (200 mm) Dri-Prime pump, with a pumping rate of 2000 gpm (7600 lpm) and 165’ (50 m) TDH, is very powerful Dri-Prime pump for storm water dewatering, environmental cleanup and sewer bypass.  In addition, we have 4 inch (100 mm) trash pump with pumping rate of over 700 gpm (2660 lpm) along with submersible electric and hydraulic pumps.

  • Hydro-Jet Flushing of Drainage (sewer, industrial and storm drains)

Common to home, hotels, restaurants, factories, commercial properties, towns and cities around the world is the need to maintain a clean and sanitary environment suitable for humans to live and work.  This responsibility includes providing a system for efficiently moving both wastewater (sewage) and storm water along with the solid materials through a collection system from the source to an environmentally safe place of treatment and disposal.

A wastewater collection system is typically a network of pipes, manholes, cleanouts, traps, siphons, lift stations and other required structures to collect all the wastewater from an area and transport it to a treatment plant or disposal system.  Some systems are “combined systems” which are designed to collect both sanitary wastewater and storm or surface water runoff.

Blockages are caused by obstructions in the pipe, such as roots, grease, debris, broken pipe or a joint failure.  Partial or complete interruption of the flow may result from an obstruction in a sewer.  When a stoppage occurs, material will backup and eventually overflow the system up to the point of the blockage.  Streets, homes, and businesses can be damaged from the debris as well as fresh water resources.  Human health is threatened with unsanitary conditions and the spread of germs and disease if untreated sewage is discharged into the environment prior to reaching sewage treatment facilities.

A storm drain system is designed to drain excess rain and ground water from paved streets, parking lots, sidewalks, and roofs.  Storm drains vary in design from small residential dry wells to large municipal systems.  They are fed by street gutters on most streets and freeways, as well as towns in areas which experience heavy rainfall and flooding.  Many storm drainage systems are designed to drain the storm water, untreated, into gullies, rivers, streams or the sea.

Stormwater run-off often carries gravel, sand, leaves and other street debris.  This material often runs down the system after it has rained, creating build up within the storm sewer system.  When the rainwater can no longer flow down a system because pipes and culverts are blocked, streets will become flooded which creates hazardous or impassable travel conditions.

Storm drain lines need to be cleaned regularly.  Routine cleaning reduces the amount of pollutants, trash, and debris both in the storm drain system and in receiving waters.  Clogged drains and storm drain inlets can cause the drains to overflow, leading to flooding, increased pollution and erosion.  Cleaning reduces the amount of debris and sand in particular, that can settle at the bottom of the large diameter pipes, reducing the capacity to efficiently carry the runoff water during rainfall.

Areas with relatively flat grades or low flows should be given special attention because they rarely achieve high enough flows to flush themselves.

Leaves, sticks, cans, bottles, bags and other large debris can infiltrate a storm system through gutter grates.  Significant amounts of sand and gravel can also build up on the bottom of storm lines.  The accumulated debris prevents the storm water from draining effectively, causing backups that flood parking area and streets.

The best way to keep a sewer or storm system working properly is to perform routine inspection and cleaning.  The objective of a sewer cleaning and maintenance program is to operate and maintain the wastewater collection system so it will function well.

The following are systems that we flush:

  • Municipal/central sewer line
  • Storm water drain
  • Main sewer line inside house
  • Floor drains
  • Service line/lateral from house to central sewer
  • Sewer line from house to septic tank/absorption pit
  • Outlet pipe from septic tank to leach field/absorption pit
  • Leach field distribution box and lines
  • Lift station
  • Grease lines
  • Manholes
  • Roof drains

Hydro-Jet Flushing Process

Hydro Jetting is typically done through a manhole or an opening called a cleanout, which is an accessible opening present in every plumbing system designed to allow access to easily “clean out” debris and flush drain lines.  A Hydro Jetter consists of a large tank of water, a special high-pressure hose, a special high-strength nozzle, and a machine which pressurizes the water in the hose so that it can spray out of the nozzle at a pressurized rate of up to 2,000 psi and a flow rate of 45 gpm.  Every plumbing system is designed to carry waste water “downstream” by gravity.  The Hydro Jetting nozzle is placed at the “downstream” end of the manhole/plumbing system and it works its way “upstream” against gravity.  As the hose is pulled back to the manhole or clean out, the water that flows through the orifices; at specific angles, sweep the pipeline/culvert.  The debris that is cleared out by the Hydro Jetter will harmlessly flow downstream where the drainage path is already clear.  The Hydro Jetters are capable of clearing out sewer lines over a length of several hundred feet.  Our equipment is capable of clearing blockages in underground drains 1 inch to 42 inches (25 mm to 1050 mm.  We carry various types of specialized nozzles to handle every situation, from sand, mud, plastics and bottles, to root infiltration.  Included is a ‘lil devil’ that will sweep clean the floor of all larger drainpipes.

  • Heavy sludge/mud pumping (heavy crude oil, sewage, slurry, petroleum)

  • Water Leak Detection/Identification (water, sewage, gas, drainage and industrial piping)

We detect water/liquid leaks underground and behind concrete structures, also to test sewer system for leaks, illegal connections and abandoned pipeline not previously surveyed and identify cracks or leaks in pipeline installation.  When water is allowed to drip it creates damage and over time that damage can become unmanageable. Time after time this will lead to more damage than the eye can see at first glance. A qualified professional can find the problems and solve them quickly. When we see a problem that is waiting to happen, we tell you right away. This helps to prevent future damage.  All leak detection methods are non invasive and non destructive to your property or established landscape.

You may have a leak if you notice:

  • Your water bills are unusually high
  • You notice discoloration in the ceiling or moisture under the kitchen or bathroom sinks
  • There is continuous movement of the flow indicator on the water meter
  • The toilet continues to run even after flushing
  • You hear water running but there is no faucet on
  • You notice green patches outdoor while other sections are not so green
  • Soft spots or water logged area are noticed
  • Sections of concrete or tiled area develop depression or hollow section
  • Sections of flooring are unusually colder that adjoin areas
  • Foul Odour Detection/Identification (sewage, gas, drainage and industrial piping)

Sewer smells in a house or building can be embarrassing, annoying, unhealthy, and in some cases dangerous.  Nausea, headaches, and dizziness are common with long exposures to sewer gases. A high level of methane, a common odorless gas in accompanied sewers, is lethal and causes many.

Detecting the sources of smelly sewage gas is often a tricky task. In most cases the smell comes and goes intermittently and many customers ignore these gas smells for years before they call a professional to diagnose it. Many times the smell disappears before we arrive and is often impossible to witness or recreate the smell.

Smoke testing involves forcing smoke-filled air, under pressure, through a sewer line or drainage system. The smoke under pressure will fill the sewer, drain, vent pipes, and any connections; then follow the path of the leak, revealing the source of the problem instantaneously. Only enough force to overcome atmospheric pressure is required and will not cause any damage to your pipes. Smoke will escape from the system at any point where there is an opening or break in the line.

The smoke used is non-toxic, harmless, non-flammable, and is virtually odorless. As long as an opening exists for the smoke to flow through, smoke tests are effective, regardless of surface type, soil type and depth of lines.

Smoke testing is the most efficient and cost effective way to locate and identify infiltration and ex-filtration problems in a drainage system. Smoke testing helps identify plumbing leaks in buildings, causing unpleasant sewer gases to escape which can also cause health problems for building occupants.  Because sewer gas contains methane gas (CH4) there is a risk of an explosion hazard or even fatal asphyxiation.  The asphyxiation is a result of the person being deprived of oxygen.  Sewer gases also probably contain hydrogen sulfide gas (H2S) in lower amounts can cause a person to feel light headed and have irritated breathing and burning eyes and with higher levels of hydrogen sulfide the person can lose consciousness immediately and result in death.  In addition there are possible health hazards from sewer gas exposure, such as a bacterial infection of the sinuses (which can occur due to any sinus irritation).  Depending on the sewer gas source and other factors such as humidity and building and weather conditions, mold spores may also be present in sewer gases.

Foul Odour Emission Sources

  • Dried up traps for sinks, showers, tubs, or floor drains not used often.
  • Cut pipe in a walls
  • Open clean out caps covered by flooring
  • Cracked pipes or broken pipes in walls
  • Cracked or broken plumbing in floor
  • Vent pipes too close to fresh air supplies
  • Buried manholes
  • Leaking manholes
  • Unconnected sewer line
  • Clogged sewer pipes
  • Abandoned sewer or drain pipes in a ceiling or floor
  • Clogged plumbing vent
  • Septic needs pumping

WAYMAH specializes in odor detection to pinpoint the origin of dangerous and   unpleasant sewer gas, illegal connections, abandoned pipeline not previously surveyed, identify cracks or leaks in pipeline installation.  Through the use of special equipment and a series of non-intrusive tests, our technicians can locate the source of the odor leak, even if it is located behind walls, under concrete floors, and above finished ceilings.

  • Locate Underground Utilities, Pipes and Cables (pipeline, septic system, manholes, electric, fiber optic and telephone cables)

It is important before an area is excavated or cut, that the area be surveyed to determine if there are any underground utilities.  Doing so could prove very costly and caused major disruption and possible death.  We use electromagnetic 2D and 3D ground penetrating radar scan to track and trace underground pipeline to determine their location and depth also identifying septic systems, manholes, energized and none energized cables.

  • Microbe Treatment (drains, septic systems, grease traps, sewage treatment plants, soil remediation – petroleum spill/leak)

Drains gets clogged from time to time.  Likewise grease trap/interceptors requires frequent cleaning.  Septic tanks have organic matters that requires removal periodically by a pumper truck.  As the same for an absorption pit or a tile/leach field that gets clogged up as a result of reduced percolation.

This is a highly concentrated formula of live vegetative bacteria used to get rid of organic material and odour in septic tanks, absorption pits, grease traps, slow flowing drains, lift stations and Wastewater Treatment Plants (WWTP).  It also reduces BOD, COD, TSS and TKN in WTP.

We blend and liquefy thick and heavy scum and sludge within manholes, grease trap/interceptors, septic tanks, absorption pits, lift stations and sewage treatment plant to allow for extraction.

We use high speed rotation machine to allow for heavy scum and sludge within tanks to be agitate and mix into an easily pumped slurry.  The machine rotating blade lifts and removes solids and sludge off the bottom of the tank while pulling the crust off the top.

  • Tank Cleaning (360º cleaning without entering the tank)

Pressure clean tanks (concrete, steel, fiberglass or plastic); of varying depth and diameter, providing 360º cleaning without manual entry; decreasing the use of chemicals, water and time by up to 80%.

Our tank cleaning machines combine pressure and water flow to create high impact cleaning of tanks.  Cleaning occurs at the point in which the concentrated stream impacts the surface.  It is this impact and the tangential force that radiates from that point which blasts contaminants from the surface, scouring the tank interior.  In conjunction with this impact, the rotation is precise, repeatable and reliable, 360-degree pattern.  This full-coverage, global indexing pattern ensures the entire tank interior is cleaned, every time.

Synchronized solid jets provide a tight and thorough scouring pattern covering all interior tank surfaces in one complete cycle.  For tough, targeted cleaning of sludge, oil, or any type of residual debris that collects at the bottom of large tanks, open-top tanks, process vessels and trailers. with high impact water jets scouring the bulls eye area of the tank, quickly and effectively cleaning difficult to removed debris.  The machine then moves the jet streams in a rotational pattern to cover the entire inside of the tank or vessel in a repeatable and reliable manner.  Tank cleaning device for any application related to the municipal industry, from manholes, wet wells / lift stations to surge tanks.  High-impact cleaning results in shorter cycle times so tanks are returned to service more quickly.

  • Thermal imaging (locate moisture, hot & cool spots in buildings, concrete and electrical apparatus)

Identify hot-spots that can lead to failures in electrical and mechanical installations, insulation losses within building savings on energy cost, water leaks within concrete structures, detecting gas leak, see through smoke filled room, determine if fires are well extinguished.

Thermal imaging is a method of improving visibility of objects in a dark environment by detecting the objects’ infrared radiation and creating an image based on that information.

All objects emit infrared energy (heat) as a function of their temperature. The infrared energy emitted by an object is known as its heat signature. In general, the hotter an object is, the more radiation it emits. A thermal imager is essentially a heat sensor that is capable of detecting tiny differences in temperature. The device collects the infrared radiation from objects in the scene and creates an electronic image based on information about the temperature differences. Because objects are rarely precisely the same temperature as other objects around them, our thermal camera can detect them and they will appear as distinct in a thermal image.

Inspecting buildings using a thermal imaging camera is a powerful and non invasive means of monitoring and diagnosing the condition of buildings. Thermal imaging technology has become one of the most valuable diagnostic tools for building inspections. A thermal imaging camera can identify problems early, allowing them to be documented and corrected before becoming more serious and more costly to repair.

A building diagnostics inspection with a thermal imaging camera can help:

  1. Visualize energy losses
  2. Detect missing or defective insulation
  3. Source air leaks
  4. Find moisture in insulation, in roofs and walls, both in the internal and the external structure
  5. Detect mold and badly insulated areas
  6. Locate water infiltration in flat roofs
  7. Detect breaches in hot-water pipes
  8. Mechanical bearing inspection
  9. Detect construction failures
  10. Monitor the drying of buildings
  11. Find faults in supply lines and district heating
  12. Detect electrical faults
  • Water Auditing (water conservation program)

Determine water consumption status, identifying wastage, leaks and high flow water fixtures.  Examine water usage and compare with activities and determine if there exist ways in which water consumption can be reduced.  Also, determine if alternative source of water can be harnessed and used for flushing and irrigation purposes.

  • Water Supply (delivery of food grade quality water)

WAYMAH provides temporary emergency potable drinking water systems to residences, businesses and commercial/municipal institutions that were in need of a temporary source of clean, potable drinking water, while their own permanent water supply was out of service.  Permanent water supplies can be interrupted for a variety of reasons, such as malfunctioning pump/treatment equipment, lightning strikes, drought, natural disasters (hurricanes and floods), or contamination from pollution sites such as leaking underground tanks.  While the reason for the interruption in the permanent water supply is being investigated and ultimately corrected, WAYMAH can provide a temporary potable drinking water system and drinking water to help you continue operating your business, taking care of your customers, or allowing you to continue to live in your home, while your water supply problem is being solved.

Products for Wastewater Systems

  • BioOne

This is 100% live vegetative bacteria that are 100% environmentally friendly and biodegradable.  Prevents the frequent pumping and cleaning of lift stations septic systems and grease traps, stops slow flowing drains and odour.  It also significantly reduces fats, oils and grease (FOG), biological oxygen demand (BOD), chemical oxygen demand (COD), total organic carbon, (TOC), petroleum, hydrocarbon, corrosion control and odour control.

  • Drain/Leach Field Filtration Chamber System (replacement to absorption pit and pipe and stone)

This is used to complement the natural process by the soil and improve performance and reliability of onsite septic system and storm water runoff; keeping your property free from puddles and ponding during heavy rains.

These filtration chambers are fast and easy to installed and have sufficient distance from the water table, reducing the possibility of bacterial contamination.  Because the entire system is underground, there is no offensive odour.  These chambers have larger effective infiltrative area per linear foot and have a greater reliability with longer service life resulting in reduced pumping and maintenance cost.

As the wastewater percolates or moves down through the soil, a variety of complex physical, biological, and chemical processes combine to provide treatment.  Particles in the wastewater are filtered by, adhere to, or chemically bond or react with the soil.  Bacteria and other organisms in the soil consume the organic matter in the wastewater and perform most of the treatment.  As a drainfield matures, organisms in the wastewater and soil multiply and form a dark layer called the biomat on or near the infiltrative surface.  The biomat is a miniature ecological system. If oxygen is present, organisms such as worms and parasites, feed on the bacteria as well as material in the wastewater.  The biomat is also where most pathogen removal occurs.  When the drainfield system is in balance, these organisms prevent the biomat from becoming so thick that it clogs the system completely, but rather, allow the wastewater to flow through the soil below at a slow, but steady rate.  The biomat also aids the treatment process in medium and coarse soils by maintaining unsaturated conditions in the soil layers below the drainfield and above the groundwater.  As the name suggests, a gravel-less system is an onsite system that does not use gravel in its drainfield trenches or beds.  Instead, these systems may use alternative materials in place of gravel, such as rubber, sand, fiber membrane, plastic, glass, or expanded clay, shale, or polystyrene foam chips.

The alternative media in gravel-less systems can function similarly to gravel.  It can support the sidewalls of the drainfield trenches and prop up the perforated drainfield pipes so they don’t lie directly on the soil and clog.  When soil is saturated from the weather or surge wastewater loadings occur, the effluent can be stored in the media until the soil absorbs it.

  • Effluent Filter

Although the main purpose of a septic tank is to remove solids from the sewage, liquid effluent from the tank always contains a substantial amount of fine suspended particles.  Effluent Filter reduces the suspended solids content of tank effluent and thereby prevents premature clogging of the soil absorption system.  The Effluent Filter is both a filtering element and a safety device that is suitable for all types of septic installation.

The process is simple: wastewater entering the septic tank flows through the filtering cartridge of the Effluent Filter whose filtration slots of 1.6 mm (1/16″) retain the fraction of suspended solids that would otherwise be released to the septic system.

The Effluent Filter offers a simple, economical and preventive solution for extending the life and ensuring optimum performance of soil absorption systems.

The Effluent Filter is generally installed inside the second chamber on the outlet of the septic tank (concrete or plastic), grease trap/interceptor and laundry area, but can also be installed in a vault box or a Filter Container immediately down-stream from the tank

For heavier wastewater flow applications, multiple filters can be installed in parallel, in which case the access openings must be large enough to allow safe and easy maintenance.

  • Odour Elimination filters

Odour elimination filter placed on vent stacks to mask sewer gas.  Plumbing vents sticking out from roofs are designed to allow sewer gases to escape and intake air to allow with proper flowing of water through drain pipes.  When you flush or turn on the faucets for the shower or sink, as water rushes into the drains, the air must escape.  Offensive odors including hydrogen sulfide gas are produced in residential & commercial drain pipes and septic systems.

Our Carbon Air Filters, sometimes referred to as Carbon Air Scrubbers for vent stack, is your answer to eliminate plumbing or septic odors.  Activated carbon scrubs the vent discharge absorbing  the offensive gases as they release out the vent stack, eliminating the septic odor problem. unpleasant odors from house, septic and portable toilet vents.  No more spoiled patio parties or foul air drifting into open windows.  Our Carbon Air filter can be easily installed in a couple of minutes and lasts for many years.  You do not need a plumber, just slip it on your existing plumbing or septic vent stack/pipe and you are finished.

The Carbon Air Filters are:

  • UV stabilized, hi-impact ABS construction
  • Universal connector fits 3 in. or 4 in.; however, will also fit 2” and 1.5” vents when used with the optional vent reducer, schedule 40 vent stack pipe (use solvent weld glue to secure) – no tools required for installation
  • Twist top for easy carbon maintenance – 8 oz. carbon filter material included
  • Replace carbon every 1-5 years or as needed, higher occupancy is equal to shorter carbon life
  • Black exterior absorbs radiant heat from the sun that helps carbon action and protects against winter freeze
  • Maximum air flow 47 CFM
  • RootX

RootX is a simple, cost-effective and proven way to kill pipeline roots in sewer lines, storm pipes and septic systems.  RootX® gives you the ammunition to kill pipeline roots treating a 400 running feet (121 meters) mainline in 30 minutes or less.

The patented RootX formula foams on contact with water to reach the top of the pipe where 90% of the roots are.  Degreasing agents strip away grease and grime so the RootX herbicide can penetrate the roots, killing the root tissue on contact. RootX promotes bacterial growth to speed the decay and natural removal of roots. The foam also leaves a thin layer of the RootX herbicide on the pipe walls to prevent re-growth.  Dead roots decay over time, restoring your pipes to their full capacity and RootX is guaranteed to keep your pipes root-free.  New root growth after treatment with RootX is much slower and less destructive to the pipe.

If this is the first time you’re treating a pipe or if it is completely blocked, it makes sense to use mechanical cutting to remove the root mass and restore pipe flow right away. However, you can kill any remaining roots in the line and stunt re-growth longer by applying RootX immediately after mechanical cutting.

It’s important to apply RootX within the first hour after cutting or wait six to eight weeks. That’s because roots release a traumatic acid to cover the cut ends and protect them against further injury. If you apply RootX immediately after cutting, the herbicide can penetrate the root ends before the traumatic acid coating is complete. After six to eight weeks, the traumatic acid will have dissipated, leaving the most vulnerable part of the root the white tender meristem growth where cells are actively dividing exposed to the herbicide.  The more root tissue you can treat with RootX, the better.

 RootX uses the aquatic herbicide Dichlobenil. It’s non-caustic, non-fumigating and non-systemic, and it contains no diquat dibromide, copper sulfate or metam sodium.  RootX will not harm pipes, wastewater treatment operations or above-ground vegetation.  RootX is classified as a General Use product by the Environmental Protection Agency (EPA), and it’s registered for use in all 50 states (EPA registration #68464-1) as well as Canada.  In addition, RootX carries the signal word CAUTION, the lowest chemical hazard rating according to the ISO 3864-2 standard for hazard severity panels.

Frequently Asked Question’s

How do roots grow in sewer pipes?
As trees and plants mature, their underground root system grows and naturally seeks out moisture. The most consistent source of moisture is sewer and wastewater pipelines. Joints and cracks in the pipe create natural entry points for roots.  Roots start to grow at the top of the pipe and spread.

Is root intrusion a serious problem?
It can be.  According to the Environmental Protection Agency, root intrusion is probably the single most destructive element involved in maintaining a wastewater collection system.  Left untreated, roots will spread throughout the pipe.  Material passing down the drain gets trapped in the roots, restricting the flow or even causing a complete blockage.  Root intrusion can eventually destroy a sewer or septic system, costing homeowners thousands of dollars to repair or replace.

Where can I buy RootX?
You can buy RootX from WAYMAH.

How is chemical root control with RootX different from mechanical cutting?
Treating pipes with RootX takes less time than mechanical cutting, and the results last longer.

Mechanical root cutting leaves some roots behind in the pipe. Cutting roots is also like pruning a tree; it stimulates vigorous re-growth in the remaining roots.  That means new root growth can fully clog your pipe again in just nine months.  What’s more the cycle of cutting roots, re-growth and cutting again will eventually destroy the structural integrity of the pipe.

RootX kills roots on contact; the dead roots decay over time and are carried out with the flow of the pipe, restoring the pipe to its full capacity.  RootX also leaves a barrier on the pipe walls to prevent future root growth.  Once you’re on a maintenance program with annual RootX treatments, you should be able to eliminate mechanical root cutting in most cases.

Should I use RootX together with mechanical root cutting?
If this is the first time you’re having your pipes treated or if the pipe is completely blocked, your plumbing contractor can clear away the immediate blockage by cutting the roots first.  Then he’ll use RootX to kill the remaining roots and leave a barrier on the pipe to prevent re-growth.  Make sure your plumber applies RootX within one hour of cutting the roots; this ensures the remaining root structure properly absorbs the RootX herbicide.  Otherwise, he’ll need to wait 6-8 weeks before using RootX to allow root ends to develop.

What’s the best location for applying RootX?
The cleanout is the preferred method for most residential applications because it’s closest to the pipes where roots can cause problems.  If there’s no cleanout at your house, your plumber can apply RootX using the toilet.  To prevent foam overflow outside the pipeline, he should only use a 2-lb. jar of RootX in a toilet application.

How long does it take to apply RootX?
Your plumber can treat your sewer or septic system by applying RootX in a cleanout or pouring it into a toilet. It takes just minutes to complete a RootX treatment.

How quickly can I expect results with RootX?
RootX kills roots on contact and destroys the root structure within the first hour after application.  The roots decay in over time depending on the type of plant and the size of the root mass.  In extreme cases where the pipe is completely blocked or close to it, your plumber should use mechanical root cutting to clear the blockage, followed immediately by RootX to kill the remaining roots and prevent re-growth.

What kind of chemicals does RootX use?
RootX kills roots using Dichlobenil, a proven aquatic herbicide. RootX also contains degreasing agents that strip away the grime on roots, allowing the Dichlobenil herbicide to penetrate the root ends.  Unlike other root control chemicals, RootX contains no diquat dibromide, copper sulfate or metam sodium.

Is RootX harmful to the environment?
No. The RootX formula is non-caustic, non-fumigating and non-systemic.  It is classified as a General Use product by the Environmental Protection Agency and is registered for use in all 50 states (EPA registration #68464-1).  In addition, RootX carries the signal word CAUTION, the lowest chemical hazard rating according to the ISO 3864-2 standard for hazard severity panels.

Does RootX harm trees and plants?
No. RootX only kills the roots inside the pipe and prevents their re-growth.  Since the RootX foam only flows through the pipe, it has no effect on roots outside the pipe.

Can RootX be used in septic systems?
Yes. RootX can be poured directly into the septic tank and distribution box to kill roots that have intruded into the tank and drain field lines.

Is RootX hard on pipes or septic systems?
No.  RootX contains no diquat dibromide, copper sulfate or metam sodium.  The RootX formula is non-caustic, non-fumigating and non-systemic.  RootX also promotes bacterial growth, which is good for septic systems.

Will the RootX foam stop or block any flow during application?
No.  RootX foams on contact with water, and it uses the natural flow of the line to spread the foam throughout the pipe.  Wastewater continues to flow under the foam, so using RootX does not cause any service interruptions.  However, you should reduce water use for at least an hour to allow the RootX foam to fully spread and soak into the roots.

How long does it take the RootX foam to dissipate after application?
The fast-acting RootX foam will normally dissipate in about 15 minutes.

How often do I need RootX treatments?
You should treat your sewer lines or septic system every year.

Products for the Construction Industry in detail

PENETRON Integral Capillary Waterproofing System for Concrete

Used for waterproofing and chemical protection above and below ground level.  Penetrates deeply and seals concrete’s capillary tracts and cracks.  Completely effective against high hydrostatic head pressure and protects concrete and reinforcing steel.  The process works with or against the pressure of water.  In the absence of moisture, Penetron lie completely dormant, should moisture reoccur at any time, the chemical action and sealing process repeats itself automatically and advances even more deeply into the concrete.  Penetron will continuously seal and reseal due to their chemical nature. Used in drinking water reservoirs, wastewater treatment tanks, foundations, basements, elevator shafts or any concrete structure requiring protection from water or chemical attack.

The complete PENETRON system includes the following products:


This is for existing concrete structures and is to be surface-applied by brush to either the positive or the negative side of the concrete. The chemical reaction that occurs begin to fill micro cracks, pores and capillaries with an insoluble crystalline formation, which prevents water and water-borne chemicals from entering, even under high hydrostatic pressure. Cracks that develop during the lifetime of the concrete are resealed by PENETRON, resulting in permanent concrete protection.


PENETRON ADMIX is a crystalline admixture in powder form that is added to new concrete during batching. Once added to the mix, it reduces concrete permeability by permanently sealing microcracks, pores and capillaries and effectively protecting the concrete against water penetration and the effects of deterioration, even under high hydrostatic pressure. PENETRON ADMIX provides projects with self-healing concrete with the ability to reseal cracks that develop during the lifetime of the concrete.


Used in combination with PENETRON for filling non-moving cracks and construction joints, form-tie holes, honey-combed areas and structurally damaged concrete. consists of Portland cement, specially treated quartz sand and a compound of active chemicals. The active chemicals react with moisture and the by-products of cement hydration to cause a catalytic reaction, which generates an insoluble integral crystalline complex. These  crystalline  complexes  grow  in  the presence of water ; block the capillaries of the concrete and  minor  shrinkage cracks,  thus waterproofing it.


A rapid-setting, crystalline-based, cementitious compound designed to stopping active leaks even under high hydrostatic pressure. PENEPLUG is recommended as a waterproof plugging mortar or where rapid-setting is required.

Construction & Expansion Joints

PENEBAR SW 45 is a unique sealing compound designed to expand rapidly when exposed to water. It is an ideal self-healing joint material for construction joint applications. Recommended for building foundations, slabs, retaining walls, storage tanks and other immovable cold construction joint.

Liquid waterproofing agent

Applied to the positive side of clean concrete surfaces free from previous coating.  This will penetrate the upper section of the concrete surface forming a hard gel penetrating any voids and cracks.

Concrete sealer for curing newly poured concrete, sealing, dustproofing & hardening concrete surfaces

Applied to the surface of freshly poured and existing concrete to seal surfaces, locking moisture for freshly poured concrete to slowly hydrate.  For existing concrete sealing, dustproofing and hardening concrete surfaces, reduce permeation of oils and other penetrating fluids.

 WAYMAH CRF Fibers, Tuff-Concrete
Secondary Reinforcement for Concrete

This is a secondary reinforcement for concrete, which significantly reduces shrinkage cracking, permeability and increase impact and abrasion resistance, eliminating the need for Fabric (Wire) Mesh in nonstructural concrete applications.  It will also produce a higher quality concrete with an increased impact strength, corrosion resistance, compressive strength and bond strength.  Needless to say all of the failings of Fabric (Wire) Mesh would also be eliminated.

Acid Stain
Etch concrete to stain existing concrete in different colour

When acid stain is poured onto concrete surfaces, it reacts with free lime in the cement and changes the colour of the concrete.  The colours are typically earthy tones and are rustic in nature.

Concrete Colour
Integral & topical colour for newly poured concrete

Colour can be added to freshly poured concrete as an integral colour, that is added at the time of concrete batching.  Colour can also be added as a topical colour to concrete after being placed.  The powdered colour is broadcasting over the surface at the point when the bleed water shows signs of leaving the concrete and is floated into the concrete.

Soil Reinforcement & Erosion Control

This is used for secondary soil reinforcement, creating a stronger composite structure, which increases the performance of the under-laying sub-grade.  Such as, weak sub-grade, heavy loads thick fill layers, high aggregate cost, contaminated sub-grades or shallow utilities, which will disrupt construction schedule and budget.  Used, but is not limited, for highways, secondary road, parking areas, airport runways, truck and freight distribution centers and terminals with heavily loaded equipment yards.

Primary soil reinforcement allows savings of 30% – 60% over concrete retaining walls, enhancing property values with naturally vegetated facing option, installs quickly and without specialized fill material, adapts to even extreme conditions and create usable land in previously undeveloped areas creating slopes up to 70°.  Application includes, but not limited to, commercial, industrial, retail, residential, transportation infrastructure, recreation facilities and municipal waste management.

Erosion control for slopes from 3:1 – 1:1 or greater for moderate to high flow channels with longevity from 2 months to 36 months suitable for highway, roadside ditches, mines, pipeline, woodlands, golf courses, residential lawns, landfill caps, severe slopes and shoreline protection.
