In order to carry out soakaway design, a percolation test to BRE365 is required, and is now also requested by local planning authorities and water authorities to prove that percolation is or is not feasible, inturn ensuring that civil engineering designers are following the SuDS hierarchy.
We provide on-site percolation tests to BRE365 allowing your engineer to calculate the infiltration rate required to size the proposed soakaway.
Percolation testing is now a compulsory report required to prove soakaways are not feasible on your site when making a Section 106 to any of the Water Authorities across the UK.
In situations where it is not possible to connect your foul drainage to a public sewer, you will want to connect to an individual treatment plant. The foul effluent from the treatment plant can be safely discharged to the ground using a Field drain. Infiltration tests must be carried out inline with part H of the building regs to design the size and length of the field drain.
Drainage strategies are now an essential requirement during planning no matter the size of the development. We work with a local engineering practice to provide a seamless civil engineering package.
