Increasingly, we all need to use water more carefully. But, equally, we want to know how much doing so would cost.
Essentially, what you save by harvesting rainwater depends on individual consumption and how the gathered rainwater will be used. It can be used outdoors for irrigation or cleaning, for example, but also indoors for flushing loos and running washing machines.
For internal use, you need separate rainwater supply pipes to your appliances, making installation more cost-efficient in a new-build or a renovation project. And if the tank is underground, a hole needs to be made. However, this is affordable compared to the overall cost of the building or renovation project.
- Peak storm water run-off is reduced, lessening the risk of flooding.
- Water bills come down.
- Plant growth is improved when they are irrigated with rainwater, which is unpolluted, and free of other contaminants, as well as salts and minerals.
- You will be maximising use of an invaluable free resource.
