Southern Water has completed a £21 million upgrade of its Pagham Wastewater Treatment Works in West Sussex – the multi-million pound project will support the local environment and new homes.

The upgrade has increased capacity at the site, by adding a series of giant concrete tanks for treatment and stormwater storage, as well as associated pipework, safety systems and electrical supplies to help run the works.
The completion comes as we continue work across West Sussex to improve the quality of the final treated effluent which leaves the company’s wastewater sites – and to cut the likelihood of storm overflows being needed when flows overload the infrastructure.
Investment is being made at Southern Water’s treatment works in Lavant along with work in villages north of Chichester including Charlton, Singleton and East Dean to reduce groundwater infiltration which can overload our wastewater sites.
Project Manager for Southern Water, Ben Gogan, said:
“We know how important it is to protect and enhance water quality and our precious environment across the areas we serve. These vital improvements add to the other investments we’ve made in West Sussex.”
The work was carried out by contractor GTb who are supporting Southern Water on a number of other key projects to treatment sites across its region.
Russell Griffiths, Project Manager for GTb, added:
“We are pleased to have completed this project in Pagham. It’s been a major engineering project over the last two years. We’d like to say a huge thank you to those residents living near to the works for their patience while we carried out this essential upgrade work.”
Near-real-time microbial monitoring of wastewater discharge and bathing waters is now possible thanks to the BactoSense ID solution created by Swiss-based bNovate Technologies.
Craig Nienaber, Business Development Manager for Safe Access Solutions (SAS) at HUBER Technology, explores why the company is seeing a growing level of interest in its safe access solutions for critical infrastructure providers, including their application in wastewater treatment assets.
