Working with Public Sewer Services, Anglian Water’s IMR Water Recycling partner, Sanivar UK have recently completed a project to refurbish a pumped effluent pipeline at Stansfield Village in Essex.

The project involved the restoration of a 100mm rising main, part of which was installed under a bridge crossing, adjacent to a pumping station. The existing PVC rising main suffered a history of bursts, and a recent leak had caused effluence to leak through the bridge decking and into a neighbouring water course. Without refurbishment, the PVC pipe posed a significant risk of pollution to the water course and adjacent amenity assets, in an area popular with walkers, Anglian Water sought a ‘no dig’ solution to minimise customer disruption and to avoid the prohibitive costs of accessing and replacing the main through traditional civil works.
