Secure Payment - Multiple Payment Gateways

 Klargester, the global-leading experts in the design and manufacture of off-mains drainage solutions, has launched the Sigma Shallow Dig Septic Tank 3800L - a cylindrical shaped tank with a lower profile for faster, cheaper off-mains installations.

The new design of the Sigma tank means that it requires a shallower dig and less excavation, as well as far less pea shingle or cement backfill to secure it in place.

Sigma septic tanks are even ideally suited to rocky strata conditions, where deep digs are not feasible. The range is fully approved to EN12566 Part 1 standard and is 99.7% efficient at retaining solids in the tank.

Did you know?


If you have a septic tank that discharges directly to a surface water you will need to replace or upgrade your treatment system by January 1, 2020 – or when you sell your property if before this date.

NOTE: Homeowners with septic tanks that discharge directly into surface water will need to replace or upgrade their drainage either when they sell their property or as soon as possible. 

Homeowners are responsible for their choice, installation and maintenance of their wastewater system under a new code of practice introduced by the Environment Agency. They have a legal responsibility to minimise the impact of your sewage waste if they manage it within the bounds of your property e.g. with a septic tank or sewage treatment plant (Binding Rules 2020, DEFRA, January 2015).
