Source control SuDS are at the top of the SuDS hierarchy, as they ensure that surface water run off resulting from a proposed development is discharged into the ground, rather than conveyed into sewers and watercourses, and hence increase the risk of flooding.
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 feasible, hence ensuring that designers are following the SuDS management train.
We provide on-site percolation tests to BRE365 in order to provide you the infiltration rate required to calculate the size of any proposed soakaway or other infiltration device.
Once a surface water connection application is made to Thames Water, there standard response is to ensure that the designer has followed the SuDS hierarchy and in some cases have insisted that percolation tests to BRE365 are carried out at the site, to prove soakaways are not feasible.
