RAINWATER MANAGEMENT
world of tougher building regulations and more volatile weather conditions, means builders’ merchants have a responsibility to provide below ground solutions which meet these new demands.
StormLine and DeepLine both feature a hydrodynamic outlet engineered to handle up to 30% more rainwater than similarly sized systems on the market,” he says. Changing weather patterns also has far-reaching implications for the sorts of products used on building sites. Part of the UK government’s push to build millions of new homes involves creating more liveable spaces. Towns and cities are expanding into previously overlooked areas, and building on previously restricted territory presents opportunities for developers and merchants. However, providing groundwater management in a

Craig Cochrane, national new build sales manager (North) at Polypipe Building Products, says that with water companies adopting new systems, and local authorities expecting more robust infrastructure, it’s vital for developers to build correctly with the right products from the very beginning – especially as development wanders into new areas.
“As standards around drainage rise, and the focus remains on sustainable systems to combat climate change, developers are also tasked with building on unfamiliar terrain. Again, this is something builders’ merchants can resolve through the supply of high-quality drainage systems,” he says.
Building has already begun on parcels of
previously undeveloped or restricted land in 2025, with 1.5 million homes planned as part of the government’s pledge to resolve the housing crisis.
“Just because new terrain is made available doesn’t necessarily mean it is ready for building. It may have poor infiltration rates and/or fallen victim to contamination, and it is through the supply of smart drainage systems like those from Polypipe Building Products that merchants can really help developers looking for a solution.
It is likely that some new housing developments will be built on floodplains. According to the Environment Agency (EA), there could be an increase of up to 50% in the number of houses built on floodplains over the next 50 years,” Cochrane adds. New housing developments may find an issue with water-retentive land thanks to the impact of climate change and the increasing
