A development of new homes in and around a converted 18th Century mill building in Worcestershire is using Forterra’s Aquaflow sustainable urban drainage system (SuDS).
The new homes at Nash Court, in Belbroughton share a car park built above a culverted stream which used to power the old mill.
This was a challenging site to design, due in part to the stream beneath the parking area, which meant connecting the homes’ external drainage to the culvert was not an option, and a standard Tarmac base layer could not be used, as surface water would not have drained effectively.
1,200m2 of Forterra’s Aquaflow and Aquapave SuDS solved the drainage issues and was also the most cost-effective infiltration system of its type.
To drain surface water from the car park and roofs, Forterra designed an infiltration system within the pavement itself, making use of the natural permeability of the ground. Hidden distribution boxes below the car park connect to the rainwater downpipes from each home delivering roof runoff straight into the permeable paving system.
The special sub-base aggregate ensures water can then gradually soak into the ground over a wide area. A block paved finish was selected from Forterra’s wide range of products and in no more time than it takes to construct a normal car park the development was finished and ready for customers.
