Yorkshire Water has reached a major milestone in a £78 million project to improve river water quality in the River Don.
The turning on of the new inlet works at Blackburn Meadows waste water treatment works in Sheffield signalled a significant stage in the investment being made by Yorkshire Water.
The second stage, which will significantly reduce ammonia levels in the water, will hopefully be turned on in the next two to three weeks.
Blackburn Meadows is one of the largest waste water treatment works in Yorkshire and treats waste water from a population equivalent of over 800,000 people from the Sheffield area.
The inlet works are the first stage of this sewage treatment and consist of a series of pipe bellmouths where the sewage enters the site and filter screens, which remove any solid material that could potentially cause blockages further in the treatment process
Improvements at the site, which started in May 2012, will continue until the end of this year and include a new inlet works, a new activated sludge plant, improvements to the storm overflow system and a sludge digestion plant, which is a more environmentally beneficial way of recycling the waste end-product.
