With average UK annual temperatures predicted to rise by up to 2.5°C over the next 70 years, climate change is already driving the need for innovative solutions to the management of rainfall and surface water.
Changing rainfall patterns are likely to lead to wetter winters and drier summers, sea levels are expected to rise and extreme weather events look set to become far more commonplace. Rainwater re-use solutions offer a way to address this increasingly important issue by collecting and recycling rainwater, rather than simply allowing it to drain away. This not only reduces the demand for mains water for toilet flushing, laundry, vehicle washing and irrigation purposes, but also eases the potential for flooding which can be created when rainwater deposited by extreme storms is simply left to run to ground.
Polypipe Rainstream offers a range of highly-effective solutions for the storage, filtration and re-use of rainwater in commercial applications. These systems have been designed to help conserve one of our most precious resources and also help clients, architects, public health engineers, main contractors, mechanical contractors and end-users conform to numerous environmental and legislative standards. On average a non-domestic building uses approximately 2,600 litres a day, with up to 80% of the water delivered for non potable applications such as toilet flushing. Much of this could be provided by harvested rainwater.
