Water & drainage

Engineers on a the Kingswood housing development in Hull have re-specified the design for 2000m of combined kerb drainage from concrete units to a plastic alternative.

Consultant PDS redesigned the layout using the 305 Envirokerb system, which is manufactured entirely from recycled plastics and aggregates. The product, manufactured by Pipeline & Drainage Systems, has been made to look exactly like concrete but at 16.5kg, each unit is 50.5kg lighter than its concrete counterpart.

A spokesman at contractor Balfour Beatty said the company preferred to use the plastic units because the use of a fully recycled material conforms with its environmental policy. And because it is so light, the system has obvious health and safety related benefits, he added.
