Which developments best suit the rainwater harvesting system?
The full house system is designed for new-build as the cost of altering the plumbing of existing houses can be substantial. Existing properties can utilise the garden and outside loo and tap systems. If you are building an extension, then it is possible to use the full house system for any toilets there, as with new-build. The tank can be installed either at the groundworks stage or at the end, but the plumbing must be done at first fix.
