We’re investing £5.5 million to upgrade Portswood Wastewater Treatment Works in Portswood, Southampton.

We've started work in August 2017 to update existing equipment, decommision older units and installing a more effective odour control system.

This includes upgrading our inlet works and storm tanks, refurbishing aeration lanes involved in the wastewater treatment process.

This work is being carried out by our construction partners Galliford Try and the project is scheduled to be completed in August 2019. To find out more, click on our Frequently Asked Questions here.

Update - 28 February

We are working with our delivery partner Galliford Try, who are currently carrying out survey work of the site to locate services.

Construction works have started to build a new odour control unit and we have also started the installation of new covers over the inlet works and holding tanks.

As well as the works on site, Southern Water and Galliford Try have set up a £5,000 Community Grant, which has been divided between several key local causes and projects within the Portswood area.

We'd like to thank all those for their applications, and to the local Councillors’ Vice-Chair of Portswood Central Residents Association, David Wardell and Southampton City Councillor for Portswood, Paul O'Neill, for joining our panel to help allocate those grants.
