South West Water Ltd is to install Bluewater Bio Ltd’s HYBACS® process to upgrade its Newquay sewage treatment works (STW) in Cornwall, UK.

The STW, which serves Newquay, Crantock and Porth, has a catchment area covering a major tourist destination with popular beaches. Built in the 1990s, the existing plant treats a resident population equivalent (PE) of approximately 55 000. During the busy summer months the works can receive an additional 40 000–50 000 PE.

The upgrade at Newquay will include the installation of four SMART™ Units to convert the existing conventional activated sludge process into a HYBACS configuration. The SMART units are assembled and tested offsite in accordance with Design for Manufacture and Assembly (DfMA) principles.

South West Water’s delivery partner Tecker will construct the pumping arrangements so that the units can be fully installed off-line and that the treatment process remains fully functional during construction.

Fergus Rooksby, commercial director of Bluewater Bio, said: “HYBACS’ ability to increase capacity swiftly and simply, with minimal operator intervention makes it an ideal solution for SW Water and their delivery partners.”
