Fully integrated estimated costs
A Fully Integrated System provides you with Municipal Back Up, and the additional benefit of harvesting Rainwater (which is free and makes this system cost effective).
A Fully Integrated System is a combination of both Rainwater Harvesting and Municipal Back Up. It provides you the benefit of reducing your reliance on regulated water (municipal back up), as well as saving water (rainwater harvesting), and still gives you access to an adequate water supply when there is none.
The water needs to be filtered and sterilised as it is utilised for full domestic water supply.
