Re-Using Rainwater
 
Toilet and urinal flushing
 
Rainwater is perfect for toilet and urinal flushing - often the highest consumer of water in commercial buildings, schools and colleges. Using rainwater for this purpose can cut mains water consumption by up to 80%. Polypipe Rainstream systems incorporate a mains water backup to maintain operation if sufficient rainwater is not available.
 
Laundry washing
 
Although great efforts are made by equipment and detergent manufacturers to reduce the environmental impact of laundry washing, the actual water consumption is often overlooked. 'Soft' rainwater needs less detergent and is also beneficial to the machine as it prevents lime scale build-up - an important advantage for commercial laundries, health clubs, hotels and prisons.
 
Vehicle Washing
 
Buildings with large roof areas such as distribution centres and train stations often collect more rainwater than they need for toilet flushing, with the excess being available for vehicle washing. Again, 'soft' rainwater requires less detergent and leaves a streak-free finish.
 
Commercial wash down
 
The UK's roads and pavements are washed by nature every time rain falls. The same rainwatercan provide a cost-effective solution for washing down commercial buildings, retail outlets, visitor centres and markets.
 
Irrigation
 
Garden centres, sports grounds, stadia, public gardens, and landscaped areas can also benefit from rainwater re-use. With no dehydrating chlorine or salt content, rainwater will keep grass and plants watered and healthy.
 
Water quality
 
Polypipe Terrain advises that the available water quality and intended use are carefully considered and a risk assessment completed where necessary. The company's technical team is always available to advise on such issues.
