Severn Trent Water’s latest innovation in wastewater treatment went live this month, when the new Nereda facility at Walsall Wood Wastewater Treatment Plant (WWTP) became operational.

Walsall Wood WWTP in the West Midlands represents Severn Trent Water’s first use of Nereda technology, although there is already over 65 Nereda projects completed or being delivered across the world.

Severn Trent Water selected Nereda technology in order to meet the stringent new standards for phosphorus and ammonia levels in wastewater. The company needed to find a solution that would deliver the necessary environmental benefits at the same time as being cost effective in terms of capital expenditure and whole life costs. The new plant is already treating 50% of the incoming flow and should be fully compliant by Summer 2019.

Delivered by Mott MacDonald Bentley, the work consists of three Nereda reactors, each with a capacity of 1500m³. Neil Durose, Project Manager for Severn Trent commented: "The start-up at Walsall Wood has gone smoothly and early indications suggest that the plant is already performing well. The whole project team has worked together to achieve this fantastic milestone and we are looking forward to a controlled ramp-up of flows and full compliance later in the Summer."

Nereda is an established game-changer for sustainable wastewater technology. It offers the optimum solution for communities facing growing urbanisation and improved environmental protection. For further information on Nereda visit www.nereda.net.
