 BU478 Rainwater collection for domestic use

BU478.jpgThere is no shortage of rain over New Zealand as a whole, but councils spend millions of dollars each year collecting, treating and supplying potable (drinkable) water to their communities. Using collected rainwater can significantly reduce demand for mains water supply.

The bulletin covers

  • benefits of collecting and using rainwater
  • system components and materials, including the roof, gutters and downpipes, screens and diverters and storage tanks
