Location:
The site of the septic tank is usually determined by the location of major bathroom plumbing. Septic tanks should not be located within 6' ft (1.5 m) of a building or property boundary.
The tanks should not be located near high traffic areas where it could be subjected to excessive loads. The location should be accessible to a driveway or other acceptable route so, a sewerage truck can be driven close enough to pump out the sludge and clean the tank.

Aerobic Treatment Units
- Features
- Wide base for stability, ease of handling and storage.
- Powered by small, silent linear air pump.
- Convenient size uses less space than conventional systems.
- Reduces the size of leaching fields.
- Manufactured from impact- resistant prime grade polyethylene.
- Spherical design ensures exceptional strength.
- Treats effluent so it can safely enter the environment.
- Specifications
- Installation
- Maintenance
- Minimize the loads: The less water that goes down the drain, the better your system will work. Conserving water will help avoid overloading the system.
- Avoid using the system for Garbage Disposal: Undigested food scraps take much longer to break down, so a garbage disposal will increase the amount of solids on your thank by as much as 30 to 50 %, and therefore the tank must be pumped more frequently.
- Heavy loads (including vehicles driving over) should not be superimposed on top or around the tank; this will cause the tank to collapse.
- The list of items below are not allowed to enter a septic tank:
- Excessive fats, cooking oils & grease
- Paints, solvents and motor oil
- Fertilizer, pesticide, garden and harsh chemicals
- Diapers, sanitary napkins, tampons, condoms
- Plastics
- Enzymes or additives
What is pumping?
Septic tanks are pumped by a licensed pumper with a vacuum tank
truck. The pumper will use a hose and vacuum everything out of the tank.
(Both liquids and solids).
Routine cleaning/ pumping
- For Aerobic Systems: The filter from the air pump must be cleaned every 6 months and the air pump must be mandatory serviced annually.
- Maintenance of the effluent filter is very important, since solids accumulate on the filtering screen and will eventually block it. For this reason filters need to be cleaned every two to three years.
- For best results, a septic tank must be pumped out periodically, usually 3-5 years. However, this is dependent on the number of users as well as the size of septic tank.
- To determine when it is time to pump out your septic tank, a simple inspection can be undertaken. This is done by measuring the depth of the sludge and scum (neither should exceed 0.5 metres) using a firm clear 1 plastic tube (about 8 ft in length) and inserting this slowly into the tank. Once the tube has reached the bottom of the tank, place your thumb over the open end and withdraw the tube. This provides a cross sectional view of the tank and the depth of each layer can then be estimated.
- Once the contents are pumped out, the septic tank must be immediately refilled with water. Failure to do so can result in the tank collapsing.

Aerobic treatment units can be installed above or below ground and may require electrical connections, additional excavation, installation of pretreatment/final treatment components and access for maintenance.
Once your tank has been installed, make a diagram of where it is located for future reference, indicating number of feet from a particular point of the house.
For a septic system to function properly it is important that it receives regular inspection and a proper maintenance.

Grease Traps
- What is a Grease Trap?
- Features
- Manufactured from prime grade polyethylene, providing exceptional strength and durability
- Leak proof, seamless constructed tank, manufactured with high quality material that provides enhanced stiffness in combination with impact-resistant properties
- Lightweight, easy to handle and install yet durable and sturdy to withstand the most rigorous applications of the plumbing industry
- Matching cover with recessed bolt holes and corrosion resistant screws
- Superior to metal, fiberglass or specially treated materials that are promoted as preventing corrosion. These grease traps include a fully integrated surface guaranteed not to corrode, chip or peel
- Trap is furnished with NPT connections and removable flow diffusing baffles
- Specifications
A grease trap works by slowing down the flow of hot greasy water, allowing it to cool with the fats and oils separating, solidifying and rising to the top of the tank. By use of baffles inside the tank, the hardened grease is prevented from passing through the drain lines. Food solids settle to the bottom of the trap. Proper tank sizing is imperative, as a tank too small for the volume of water passing through it will force the grease into the drain lines.
Additionally, proper maintenance is also crucial, as un-maintained traps will eventually fill with waste to capacity, and the pressure caused by the draining of a full sink, force the solids out the sewer pipe, eventually hardening and jamming the line.
Grease will stick to surfaces that are less wet, or from the top of a drain pipe down towards the flowing water, slowly constricting water flow, eventually forming a total blockage. Sewer systems cannot handle grease and it must be removed from the system.

- DB - Air pumps (for Aerobic Treatment Systems)
- Highly recommend for their efficiency and reliability.
- Quiet Operation.
- Low power consumption.
These extensions allow the tank to be buried deeper into the ground and provides easy access for cleaning.
Available for all septic tanksFilters the effluent leaving the septic tank, ensuring that no solids enter the soak away.
Available for all septic tanks
Kam Air Linear Aerator Pumps are used on Aerobic Digesters to inject air into the system, with the purpose of treating the waste water, allowing the solid breakdown to occur.
* Your Air pump choice must be based on the size of the tank and the number of users. The more users, the higher flow rate the system will require for an effective breaking down to occur.
