Renewable Energy Scheme:  Esholt
Client:   Yorkshire Water

In a hydropower project completed for Yorkshire Water, our subsidiary, Mott MacDonald Bentley, has installed a hydro-turbine power generation station to generate renewable energy from the waste water treatment works process at Esholt in West Yorkshire.


We installed two new Archimedean Screw type hydro-turbine generators in series between the Inlet Works Detritors and the new Primary Settlement Tanks.

Flow, of up to 3,240 litres per second, now passes through a 1,800mm diameter pipe to the Hydro-Turbine Power Generation Station to generate 180kW of renewable energy in the first installation in the UK to use untreated sewage for hydro power generation.

The electricity generated from the hydro-turbines is used to reduce the imported power demand of the treatment works.
