Are you concerned about your water use? Have you received an excess water use bill (in Christchurch) or do you have high water use charges (other districts)? You may be interested in rainwater harvesting.
Due to climate change, extreme flooding events and droughts will be much more likely in the future. Rainwater harvesting can help with both. With your own rainwater tank, you can collect water from your roof which you can use to water your garden or wash your car during a drought (when there may be tap water restrictions for those uses). During heavy rainfall events storm water systems are often overloaded which can harm the environment. Storing rainwater from your roof for later release (or use), can help those storm water systems cope better.
Our rainwater tank installation service, includes a tap in the tank so water can be easily accessed. An installed overflow means any excess water when the tank is full, goes back into the storm water system.
