서번트렌트(Severn Trent)는 지역 전체의 강 건강을 개선하기 위해 우수토구(雨水吐口, Storm Overflows)에 44억 파운드 이상을 투자한다고 발표했다.

미들랜즈에 본사를 둔 서번트렌트는 우수토구 월류로 인한 유출수를 줄이려는 계획의 일환으로 2050년까지 25년 동안 투자를 진행할 예정이다. 이러한 투자 중 일부는 물 공급의 보안을 보장하고 지역의 상하수도 시스템을 크게 개선하기 위해 2025년부터 시행될 129억 파운드 규모의 투자 프로그램의 일부다.

총 2천472개의 우수토구에 대해 저수 탱크 용량 증가부터 자연기반해법(NBS) 도입에 이르기까지 다양한 개선을 통해 각각 고유한 개별 조치 계획에 대한 투자가 진행될 예정다. 또한 서번트렌트는 우수토구의 100%를 모니터링해 강을 그 어느 때보다 더 자세히 모니터링할 수 있도록 투자하고 있다. 현재 서번트렌트는 투자 우선 순위를 정하는 데 도움이 되는 연간 약 3억 개의 데이터를 분석하고 있다.

개선 작업은 우수토구 실행 계획(SOAP)의 일부로, 서번트렌트가 관리하는 카운티 전체에 걸쳐 나뉘어 진행될 예정이다. 개선이 이루어짐에 따라 정기적으로 업데이트될 이 계획은 2040년까지 우선 순위가 높은 지역에서 연평균 10회 이상 유출이 발생하지 않도록 할 것이며,정부 목표보다 5년 앞선 2045년까지 지역 전체의 수로로의 유출 건수를 줄일 계획이다.

밥 스티어(Bob Stear) 서번트렌트 수석 엔지니어는 "이번 투자는 서번트렌트 지역을 위한 거대한 장기 투자 계획이며, 앞으로 몇 년 동안 우수토구를 개선하고 강에 이익을 가져다 줄 것"이라면서 "이번 발표는 강의 건강에 있어서 실질적인 개선을 제공하기 위한 서번트렌트의 노력에 있어 또 다른 중요한 이정표다"라고 말했다.

세번 트렌트는 최근 새로운 투자 기간이 시작되는 2025년까지 기다리지 않고 지출을 가속화하기 위해 자금 조달과 계획 전달을 돕기 위해 주주들로부터 10억 파운드의 추가 자금을 확보했다. 유출량 감소에 기여하기 위해 설계된 70개 이상의 프로젝트가 2024~5년에 완료될 예정이다.

레스터셔(Leicestershire )주 힝클리(Hinckley)에 새로운 저수 탱크를 만들고 합류식 하수관거를 분리하고 노팅엄셔(Nottinghamshire )주 칼튼(Carlton)에 유출량을 절반으로 줄이기 위해 저수 용량 확장

맨스필드(Mansfield)에 7천600만 파운드를 투자해 지역사회 전체에 이익이 되도록 지속 가능한 배수로 설치

스트라우드(Stroud) 지역 미래의 하수 범람을 줄이고 지역의 강을 보호할 하수관로 개선 프로젝트에 2천500만 파운드 투자

슈롭셔(Shropshire)와 워릭셔(Warwickshire)의 50km 이상의 강을 따라 수질을 개선하기 위한 7천800만 파운드 투자

서번트렌트는 계획이 진행됨에 따라 모든 유역의 우수토구에 대해 어떤 조치가 계획되어 있는지에 대한 정보를 공유할 계획이다.

Severn Trent to invest £4.4 billion on its storm overflows across the region  

Severn Trent confirms major 25-year investment plan to improve storm overflows £4.4bn to be invested across its network on a mix of improvements including increasing capacity of storage tanks and designing nature-based solutionsInvestment is part of Severn Trent’s Storm Overflow Action Plan to meet government and industry targets, helping rivers be the healthiest they can be

Severn Trent has announced it will invest over £4.4 billion on its storm overflows to help improve river health across its region.

The Midlands-based water company will make the investment over a 25-year period up to 2050, as part of its plans to reduce spills from storm overflows. Some of this investment forms part of the bigger £12.9b investment programme from 2025 to ensure the security of water supply and will deliver significant improvements in the region’s water and sewerage system.  

A total of 2,472 storm overflows will undergo investment – each with its own individual action plan - with a variety of improvements ranging from increasing the capacity of 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 improvements will be split across Severn Trent’s counties and forms part of the water company’s Storm Overflow Action Plan (SOAP). The plan, which will be regularly updated as improvements are made, will reduce the number of spills into watercourses across the region, 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, five years ahead of Government targets.

Bob Stear, Severn Trent’s Chief Engineer said: “This is a huge long-term investment plan for our region, improving storm overflows and bringing benefits to rivers over 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 that 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.”

Severn Trent has been recognised as an industry leader when it comes to environmental performance, achieving the Environment Agency’s highest four-star rating for the fourth year running. And it is confident of securing this for an unprecedented fifth year, continuing to make a positive difference to the environment - whether through delivering bold Get River Positive pledges, improving the biodiversity of 10,000 hectares of land, or launching the world’s first carbon neutral wastewater treatment site in Staffordshire.

Accelerating improvement and investment activities

Severn Trent recently raised £1bn of additional investment from its shareholders to help finance and deliver plans sooner, being able to move and act now to accelerate spend, rather than wait until 2025, when the new investment period starts. More than 70 projects designed to contribute to spills reduction will be completed in 2024/5, worth around £384m including:

Creating new storage and combined sewer separation at Hinckley, Leicestershire and increasing storage to halve spill volumes in Carlton, Nottinghamshire 

£76m investment in Mansfield installing sustainable drainage to reduce flooding to benefit the whole community

A £25million project in Stroud to upgrade the sewer network which will reduce future sewer flooding and also protect rivers in the area. The new CSO site and extra capacity will mean that there will be fewer activations into watercourses, such as the River Frome.

A £78m investment to improve the water quality along more than 50km of river in Shropshire and Warwickshire and help move two stretches (on the rivers Teme and Leam) towards bathing quality by 2025

As schemes progress more detail 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.

The investment forms part of Severn Trent’s Storm Overflow Action Plan, which was published today following discussions with the Government, Defra, the Environment Agency, Ofwat, and other key industry stakeholders.

The plan, which will be updated as improvements are made, reveals steps being taken by the water company to meet targets set out in the Government’s Storm Overflows Discharge Reduction Plan (SODRP).
