The multi million pound contract has been awarded to Kier Natural Resources, Nuclear & Networks, for upgrades at Portswood Wastewater Treatment Works, in Southampton, and Thornham Wastewater Treatment Works just over the border in West Sussex.
Portswood will have new technology installed to reduce nitrogen levels in the water leaving the site after treatment, and Thornham will get a new UV disinfection system in an effort to go further in protecting local shellfish water quality in Chichester Harbour.
The work at Thornham will also include increasing treatment capacity to support population growth in the region.
Simon Tomlinson, Director for Capital Delivery at Southern Water said:
