Project Details
Location:
Wessex Water Treatment Works, Sutton Poyntz, Weymouth
Hydro Source:
Capped spring
Client's Brief:
Generate power from water flowing down a pipe from a spring head to the treatment works. Integrate the turbine control system within the site according to Wessex Water’s accepted operating practice.
Solution Chosen:
Cross-flow Turbine
Site Data:
Head 8m, Flow 0.15 m3/sec, Power 7 kW
Summary:
This challenging project was commissioned in June 2011. The cross-flow turbine now perfectly performs the function of the old flow control valve and generates a very useful contribution towards the electricity consumption of the water treatment works. A good example of how hitherto wasted energy can be realised from pressure reduction in piped systems.
