Water Collection System
For the water collection system, we encourage the use of water tanks for the collection of rain water which can then be used, after filtration, in your home as drinking water (no more purchasing of filtered water), general water use and if you have enough capacity, in your garden.
The sizing of this system will depend on the space you have available for tanks and if you want to look at an above-ground or an underground water system.
The cost saving will naturally depend on the size of the system and water usage of your home. An entry level system with 2 tanks, pump, filter and piping will be in the vicinity of R15 000 and this will be repaid over 7 years, calculated with a saving of R250 per month.
