A sustainable solution to drainage for this new housing development

This exclusive up-market housing development in rural Somerset, required surfacing for what would become an adopted residential road. Planning requirements specified that a sustainable form of drainage would be needed to gain planning consent. The rural greenfield location of the site meant that installing a new conventional drainage system would be difficult and would require a separate contractor adding time, cost and disruption for the developer.

After discussing the requirement with the independent design engineer and local authority highways team, ULTIDRIVE POROUS, Tarmac’s durable porous asphalt was recommended. It would allow full infiltration of rainwater to eliminate puddles and standing water even after heavy rain. It would also achieve a safe, all-weather surface for residents and avoid surface run-off into the local catchment. The approach taken, meant that no drains or manholes were required, which is another advantage of using this product for architects and designers. It would also be a fast and cost-effective solution for the developer as it would avoid the need to install pipe work for a new drainage system. For the local authority, the new pavement design met planning requirements for a sustainable drainage solution that would manage rainwater at source and avoid local flood risk. It would also deliver lasting durability, helping to minimise future maintenance requirements.
