Severn Trent has announced it will invest over £630 million in its storm overflows, improving river health in Nottinghamshire.
The water company will invest over 25 years up to 2050, as part of its plans to reduce spills from storm overflows across the county.
A total of 258 storm overflows across Nottinghamshire will undergo investment – which could range from increasing the capacity of its storage tanks to introducing green nature-based solutions.
The company is also investing to ensure rivers are monitored closer than ever before with 100% of its storm overflows with monitors – and the company is now analysing around 300m pieces of data a year helping to prioritise investment.
The investment for Nottinghamshire forms part of a wider £4.4bn injection into 2,472 storm overflows across the Severn Trent region, as part of the water company’s Storm Overflow Action Plan (SOAP).
The aim is to reduce the number of spills into water courses across the county, ensuring that by 2040 no overflow will spill more than 10 times in an average year in high priority areas, and in all areas by 2045.
Bob Stear, Severn Trent Chief Engineer said: “This is a huge long-term investment plan for Nottinghamshire, improving storm overflows and bringing benefits to rivers now and during the coming years.
“Today’s announcement marks another significant milestone in our drive to deliver real improvements in river health.
“This is why we launched Get River Positive which has already delivered great results, despite the region having experienced seven named storms between September and December, contributing to some of the wettest months on record. And we know there is still more to do, which is why this investment is so important – not just to us, but to our region’s rivers and the communities they serve.”
Since launching its Get River Positive, Severn Trent has delivered strong results and committed to significant investment in Nottinghamshire, including;
· A £76m investment in Mansfield through Severn Trent’s Green Recovery programme, using nature-based solutions (Sustainable Drainage Systems (SuDS)) to reduce the risk of surface water flooding during storms. This will also mean a reduction in storm overflow spills.
· A £14 million project at the wastewater treatment works that serves Worksop and the surrounding area, which will improve the quality of effluent discharged to the river to benefit river health. A new storage tank will also be constructed to increase storm storage capacity.
· A £17.8m investment to upgrade Toton Sewage Treatment Works to achieve a higher level of treatment and improve the health of the River Erewash.
As schemes progress more details will be shared on what action is planned for every storm overflow in every waterbody. A live ‘Event Duration Monitor’ map is due to be launched later this year, which will be a great tool for people to see what investment plans are taking place on all storm overflows across the region.
