GASES from sewage processed at a water treatment works are being used to generate renewable energy.

Southern Water has installed a new piece of kit at its Budds Farm plant at Broadmarsh, Havant.

The new heat exchanger has been added to the site’s Combined Heat and Power (CHP) plant which captures bio-gas created during the treatment process.

This gas, which would otherwise have been burnt off in a flare, is used to produce renewable energy with any surplus exported to the National Grid.

Morné Cloete, project manager, said: ‘This new heat exchanger means we are able to recover even more energy from the wastewater treatment process.

‘I’m sure people will be delighted that they are helping us minimise the environmental impact of our business, dealing with their business – by generating electricity with poo power. CHP plants help us reduce our carbon footprint.’
