Polypipe Civils & Green Urbanisation welcomes new Environment Bill provisions to tackle storm overflows
On 11May 2021 itwas announced that newlegal duties onwater compnies and governmentwill be included in the Environment Bill to reduce sewage discharged intowaterways.
The additions to the Environment Bill include duties on the government to publish a plan to reduce sewage discharges fromstormoverflows by September 2022 and to report to Parliament on the progress of implementing the plan.Water companies will also have a duty to publish data on stormoverflowoperation on an annual basis.
Sean Robinson, specification director at Polypipe Civils & Green Urbanisation, said: “It’s good news that the issue of storm overflows and the discharge of untreated sewage in our naturalwaterways and environments is a key part of this legislation. Combined sewers are under greater pressure as a result of population growth, increased urban density, and the challenges we face as a direct result of climate change, such as increased rainfall and severe flooding. These problems need addressing, which iswhat the Environment Bill aims to achieve, but it’s paramountwe find newand innovativeways ofmanaging storm overflows so they limit any potential
30 damage to our naturalwater resources.
“Whilewewelcome the news that the governmentwill present its plans to reduce sewage discharges fromstormoverflows by September 2022,we urge those involved in the consultation to look beyondwhat goes underground. Thanks to breakthrough stormwater attenuation and re-use technologies,we are nowarmedwith a new generation of sustainable drainage solutions that can significantly reduce, or even eliminate, the volume of stormwater entering the combined sewerage network, reducing the risk of sewage discharge.
“These latest developments in sustainable drainage are designed to achieve greater green urbanisation – looking at howwe can retain andmanage stormwater to fuel and sustain green assets such as blue-green roofs, raingardens, tree pits and other shared green spaces across the entire built environment. By diverting stormwater away fromsewers, this approach helps to support greater biodiversity, achieve

climate change resilience, and offers multiple health andwellbeing benefits for individuals and communities. By using green urbanisation solutionswhich both reduce sewage discharged intowaterways fromstormoverflows and feed newgreen assets,we can aimto tacklemultiple problems simultaneously.
“The government, local authorities, and water and sewage companiesmustwork togetherwithmanufacturers, architects, designers, and contractors, using the Bill as a catalyst to drivemore creative, forward- thinking approaches towatermanagement, that surpass the challenge of howwe reduce sewage discharges fromstorm overflows and drive greater biodiversity benefits.”
