Project: The Buttercross

Sector: Residential

Product Type: Aquaflow / Royal Forest

Location: Oxfordshire

Size/Area:  9,500m2

Developer: Bower Mapson

Formpave’s Aquaflow Sustainable Urban Drainage System (SuDS) was the natural choice for an award-winning development of new homes in Witney, Oxfordshire.

Developers Bower Mapson specified Aquaflow for the site, which is next to the Emma’s Dyke waterway, to simplify surface water drainage and resolve any concerns regarding the quality of discharged water.

 

 

 

 

 

 

 

 

Formpave’s experienced in-house design team designed an Aquaflow SuDS infiltration system, consisting of a permeable paving surface on top of layers of Inbitex Geotextile and a sub-base of graded stone stabilised using SC Intergrid to increase the load capacity of the construction build-up. The scheme was designed to adoption standards and is soon to be adopted by Oxfordshire County Council.

The sub-base stone was created from the demolition of a former factory, and the Formpave team worked very closely with Bower Mapson to ensure high quality and well-graded material was achieved. As a result, the use of recycled material within the Aquaflow SUDS System provided a Building Research Establishment Environmental Assessment Methodology (BREEAM) rating of A+.

 

 

 

 

 

 

 

Formpave’s 80mm deep Aquaflow paving blocks allow water to permeate through to the infiltration system below, where it is initially filtered and cleaned via the inbitex geotextile layer and then a second stage within the sub-base. The aggregate grading then ensures the collected pH-neutral water can gradually soak into the ground.

Peter Mapson, Managing Director of Bower Mapson, said: “I designed a dense urban scheme for the site, with the highway filling the space between the buildings, so Aquaflow paving was the perfect answer.

“It simplified the surface water drainage, particularly where private front garden areas were limited. Because we used the Aquaflow design service from the outset, all parties understood the benefits of re-charging groundwater, plus we saved separate roof storm drainage by some discharging under the highway.

“Put simply, choosing Aquaflow fits our philosophy of developing environments which all parties can be proud of.”

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Formpave’s Royal Forest 80mm traditional block paving, in complementary Vendage, Charcoal and Burnt Red colours, was also used at the development, which was Commended in the Sunday Times British Homes Awards.
