Portswood

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 November

Further to the recent meeting for local residents and our letter of 27 October, we’re now ready to carry out work to the odour control unit at Portswood Wastewater Treatment Works.

As a result, people in the area may notice an increase in odour coming from the site.

This work is part of a scheme to reduce odour at the site and we apologise for any inconvenience caused.

Community Grant

A Southern Water community grant has been set up for the Portswood ward of Southampton, where community groups can apply for funding of up to £2,000.
