Building Sustainable, Resilient Communities
Nearly two million Australians rely on rainwater every day. In rural communities it’s been a way of life for generations, and in our cities it’s becoming essential for managing stormwater, building resilience, and securing local water supply.
Rainwater harvesting is a nature-based solution that works at every scale — from a single home to an entire city. The Rainwater Harvesting Association represents the industry making this possible, working across policy, regulation, and innovation to build sustainable and resilient communities.

National Policy
The Rainwater Harvesting Association is proud to release the first national Rainwater Harvesting Policy.
The policy calls on all levels of government to implement rainwater harvesting in urban areas through planning and building development controls to reduce the volume of stormwater and reduce the demand for water at both the lot and city scales.
Rainwater harvesting is a vast missed opportunity in our cities. The volume of rainwater falling on urban areas exceeds our annual utility water consumption and is delivered directly to our buildings. The rainwater we do not harvest instead becomes stormwater that overwhelms existing infrastructure, damaging homes and natural waterways.
