Enough electricity to power 6,000 homes could soon be produced at Northampton’s sewage works.
As part of processes currently carried out at the sewage works in Great Billing, a by-product, called bio-gas, is produced.
Currently, some of the gas is used to generate electricity, but some is simply burned off.
To harness the valuable resource, Anglian Water has revealed plans to build a new ‘sludge digester’ to maximise electricity generation.
In documents submitted to Northampton Borough Council, the firm said: “The sludge treatment centre at Great Billing currently has insufficient capacity and resilience to maximise the digestion period and produce maximum volumes of bio-gas.
“As such, gas production and power generation is being reduced and surplus bio-gas is being flared.
“The proposed development aims to provide an additional sludge digester to maximise bio-gas production and power generation.”
To enable the development, some disused facilities at the sewage works would be demolished, including two gas towers.
However, a new 78ft, flue stack would be built on the site.
Anglian Water said the development would not add to any smells coming from the sewage works.
The borough council’s planning department will consider the plans over the coming weeks.
