Water networks to generate energy through hydropower project

A new £500,000 research project could see energy generated through the water network by introducing hydropower turbines within existing water treatment systems.

BANGOR, Wales, July 15, 2011 -- A new £500,000 research project could see energy generated through the water network by introducing hydropower turbines within existing water treatment systems.

Delivered in partnership with Bangor University and Trinity College Dublin, the study will examine how energy can be recovered at break pressure tanks, in water networks, and then converted into electricity without interrupting water supply.

Called the Hydro BPT project, it is hoped that the resulting energy can be used by the water industry and surplus can be sold to the National Grid.

Dr Aonghus McNabola, of Trinity College Dublin, explained: “These BPTs are widespread, and present an opportunity to recover energy from water supply networks by means of a hydropower turbine system, producing electricity and improving the sustainability of the network without interfering with the water supply service.”

Dr Prysor Williams of Bangor University’s School of Environment, Natural Resources & Geography, said: “The water industry is very energy intensive. This project could help reduce its associated environmental impact and economic costs.”

Stakeholders across Wales and Ireland, including Dublin City Council, Welsh Water, Dulas, Isle of Angelsey County Council and Gwynedd Council, are supporting the project. It will initially be focused in North Wales before being rolled out to other areas.
