Septic Tanks

New product

A septic tank is a key component to the disposal of sewerage waste - ideal in the case of a property not being connected to a main sewage pipe. The term “septic” refers to the anaerobic bacterial environment that develops in the tank. Once bacteria has developed, it decomposes the waste and is discharged into the tank.  

NB. Lead Time 7 - 10 days

Disposing of oils, chemicals or any other non natural waste is not advised as this may block the septic tank or disturb the bacterial breakdown of the septic sewerage system.

Sewerage waste that is not decomposed, might have to be removed from the tank. If this process is not done, the septic tank fills up and may over flow.

Installation Instructions for the Septic Tank

1. FOUNDATION AND SEPTIC TANK INSTALLATION

Excavate the correct size hole in which to insert the manhole A 1:6 river and cement mix is required to cover at least 300mm across the base of the excavated hole. Make sure no solid objects are protruding from cement sand mix. Insert the manhole into the excavated hole and bed the manhole properly, by gently rocking the manhole backwards and forwards in the cement mix, making sure the manhole is accurately levelled.

2. JOINING

When joining pipes to the septic tank manhole, it is easily done by using a water soap mix and ramming the required pipes home.

3. BACKFILLING

A 1:6 concrete sand mix should be carried out in 300mm thick layers from the base up to 100mm below the top of the septic tank manhole with the concrete filled lid in place on the manhole. The backfill material should preferably be sandy and slightly moist Each 300mm layer should be densely compacted to achieve 90% of modified A S H TO maximum dry density. For manholes deeper than 2.150mm or where a high water table is anticipated, backfill material must consist of a soil crete mix of 5% cement and 95% selected granular material.

4. WORKINGS OF THE SEPTIC TANK

Activation of the tank can either be done by using an activator or alternatively placing a dead chicken into the tank.

5. HOW DO I CONNECT THE TANK?

Connect the toilet outlet to the septic tank inlet with a 110mm PVC pipe. Connect the overflow or outlet to the French drain, making sure that it is not too close to household underground water supplies, e.g.: borehole.

6. HOW DOES IT WORK?

When you flush the toilet, the content collects in the tank, therefore any solid waste product will float on the water.
The bacteria from the activator will dissolve the solid waste products and produce an almost clear water which settles at the bottom of the tank, which then flows out of the overflow and into the French drain.

PLEASE NOTE:

No cigarette butts, chemical and or household cleaning products should be in the septic tank as it eliminates the bacteria and the consequences are that the chemical process will not be able to take place.
