RAINWISE

Maintenance

On-going maintenance is essential to keep your RainWise installation working properly. We are counting on your RainWise project to prevent polluted stormwater from going into our waterways. Your cistern and/or rain garden is made possible with public funds. In return, RainWise requires homeowners to maintain their RainWise project for five years.
