Why is the project relevant to you?

Public water supply is becoming more challenging, which will acutely be felt in new or expanding businesses. This will get worse due to growth and climate change, causing more low flow events and droughts. This project focused rainwater harvesting in commercial properties to reduce non-household water demand, abstraction, and treatment. This approach is also relevant for rural industries like agriculture, which can use large roofs on barns and sheds for water storage.

Key messages for Land managers

For rainwater harvesting to work, you need either a steady water demand or large storage reservoirs for seasonal use.
