Yorkshire Water has installed a wind turbine at its Chesterfield waste water treatment works to reduce its carbon footprint and cut the site’s £50M per year electricity bill.
Kelda Water Services has been on site since April carrying out the preparatory works for the turbine, which costs £1.6M.
The turbine was made in the Netherlands and is 77m high. It will start producing electricity by the end of August and should provide between 20% and 45% of the works’ annual needs.
Yorkshire Water said it aims to generate half of its energy from renewable sources by 2020.
Meanwhile, Mott MacDonald Bentley has almost finished works at Yorkshire Water’s Stubden reservoir. The £1.5M programme has seen repairs to the spillway, so that excess flow is diverted away efficiently and the reservoir embankment is not affected by flood erosion.
The main construction has finished and the team is now working on grouting and pointing of the existing wave wall and upgrading the existing scour pipe.
