Septic Tanks

About Septic Tanks

A septic tank is designed to provide what is known as primary biological treatment to crude sewage produced in a normal domestic environment. It retains solids and allows them to settle out, where they can be partially broken by biological action so that only the remaining liquor is left to flow down the outlet drain. This liquor (normally called effluent) is then sufficiently treated to soak into the ground in an underground distribution system.

The septic tanks are designed to accommodate drain invert depths to 2 metres. However, the neck can be easily cut down to suit shallower invert levels. The pedestrian duty lockable manhole cover is also manufactured in rotationally moulded polyethylene making it lightweight and easy to handle. In addition a safety grill is available to comply fully with statutory regulations and HSE recommendations.
The septic tanks incorporate a unique patented baffle system which not only gives exceptional effluent quality but is designed to cope with the rigours of lifetime service. There are no floating balls to become clogged up or flimsy partitions to break off if de-slugging is neglected and the robust polyethylene cylindrical baffle will withstand the impact from even the heaviest de-slugging hose.
