Ground conditions vary from site to site and therefore require different types and makes of system. We therefore supply and install various makes including the Klargester Biodisc and Biotec sewage treatment plants and septic tanks, which now incorporates the Titan, Clearwater and Entec systems. Also the Allerton range including the ConSept Conversion Units, WPL Diamond plants and the Balmoral and the Conder Clereflo CT range.

We have a long standing working relationship with Klargester in particular and have been 'Klargester Certified installers' for almost 15 years.

We offer a full design and installation service which includes site assessment, surveys and percolation tests if required. We also advise on type and plant size as well as submitting all applications to the Environment Agency and Local Authorities.

For any help or advise on drainage solutions please contact us using our enquiry forms or call on any of the above telephone numbers.
