project statys delivery

Project Overview

Work to build a new multimillion pound, state-of-the-art Waste Water Treatment Works upgrade in Winchburgh started in September 2021. The new and larger works will be built on the edge of the town, next to the site of the current WwTW. The current site has come to the end of its life and the new works will provide sufficient capacity to support existing and proposed development in Winchburgh for the next decade and beyond The new works will make use of state-of-the-art Nereda technology which reduces energy usage by up to a half and treats wastewater more effectively.
Award-winning Nereda technology treats waste water much faster than current treatments and takes away the need for pumps and mixers, meaning less energy and space is needed to treat a higher quantity of waste water. It also removes the need to use any chemicals during the treatment process which better protects the environment at local waterways. 

This investment will be delivered by Scottish Water’s alliance partner Efficient Service Delivery (ESD) and will start operating by winter 2023.

Update - May 2024

Construction is complete and flows to the new nereda works have now been turned on. Demolition of the redundant works is due to commence. 

Decanting of the site welfare has commenced, and the offices will be removed in June. The site compound will be reinstated following removal of the offices and landscaping will begin.

Planning - PV solar scheme

A planning application was submitted for a PV solar scheme to the roof of the proposed control building. This will enable the site to reduce the CO2 emissions and will directly contribute toward Scottish Water's targets of increasing green energy generation and reducing our carbon footprint.
