South West Water’s Bathing and Shellfish Water Quality Programmes, Exeter

About this event

During the AMP6 - Water Investment Period, South West Water (SWW) delivered multi-million pound upgrades to Plymouth Central Waste Water Treatment Works (WWTW) and Countess Wear WWTW (Exeter) to provide significant improvements to the storm water discharges from the treatment works to provide betterment for the Bathing and Shellfish Waters in and around Plymouth and the Exe Estuary.

The upgrades saw SWW install UV disinfection on the storm overflows at both the treatment works (the two largest WWTW in the South West) delivering the two largest Storm UV installations in the UK. Storm UV treatment is still a relatively new technique and required significant modelling, investigation and negotiations with the EA locally and nationally for approval.

The talk will look at the investigation and analysis work undertaken to prove the use of Storm UV as appropriate as well as the construction challenges for the schemes.

Our evening commences at 6pm with light refreshments and a networking opportunity with the lecture starting at 6:30pm.
