Septic Tanks
Basic Septic Tanks only partially treat sewage and discharge effluent of low quality. Many authorities in the UK & Ireland prohibit their use.
Septic Tanks may be installed (subject to consent) in applications where:
- Soil is of suitable porosity.
- Installation complies with Building Regulations (Approved Document H).
- The installation will not contaminate any ditch, stream or other watercourse.

Sigma Shallow Dig Septic
The Sigma septic tank will drastically reduce the time and cost of a septic tank installation. Its EN12566 Part 1 approved and 99.7% efficient.
Sewage Treatment Plant

Case study
A treatment plant serving a 3-bedroom farmhouse
The client approached Klargester to discuss the options for replacing a failing brick Septic Tank. Key criteria were to reduce frequency of tank-emptying visits and to use existing soakaway without the risk of blockage. Major concern was also to reduce pollution of surrounding streams and watercourses.
