If you need to treat the runoff from a driveway prior to discharge to main foul sewer for your SuDS planning application but don’t have space for a swale, we have a solution for you.

We were recently approached by a SuDS consultant who had a customer that needed to treat driveway runoff but had room for any swale or other green infrastructure SuDS solution. We specified a HydroSystem 400. This upflow filter has the highest treatment performance, exceeding all UK Mitigation Indices. The multistage multi process Unit is just 400mm wide and fits standard 4-inch drainage pipes. The Filters are so easy to look after and maintain. This ensured the job could proceed, safe in the knowledge that the discharge could be made to the foul sewer. 

These tight space saving solutions are something we are always happy to advise on, either using precious rainwater, or treating stormwater runoff to a high standard. Contact our water experts for advice.
