Birse is believed to be favourite to win an estimated £20 million contract to upgrade the existing Derby sewage works at Spondon in Derbyshire for Severn Trent Water.

The contract is the first of a three-phase scheme at the plant. Work will start this month and take around two years to complete. Phase one will enable the plant to treat flows of up to 206,000,000 litres per day.

The contract, which also includes some elements of detailed design work, will encompass all civil, building, mechanical and electrical works associated with the scheme.

The work will include the construction, installation and commissioning of a diffused air activated sludge plant, a sludge-thickening plant with filter belts and centrifuges, a sludge digestion plant, along with a workshop and control building.The contract also calls for the construction of a new river crossing for vehicles and pedestrians and associated works services. A high-voltage ring main system will also be installed.
