BU503 Rainwater harvesting in commercial and industrial buildings
Much of the mains-supplied potable water used in the commercial and industrial sector, particularly for non-potable uses, could be replaced by rainwater harvested on site. This bulletin gives an overview of the design and construction of rainwater harvesting systems for commercial and industrial buildings.
The bulletin covers:
- rainwater collection components and design, including collection areas, roof materials, gutters and downpipes, diverters and screens
- storage tanks, including calculating tank size, pumps/gravity feed and backflow prevention
- design requirements
- case studies.
