Hello Tom
My group are doing a similar solution regarding water source/treatment. Does the central lagoon provide enough water already?
I am concerned that individual tanks are not enough during the dry season, how much do the current rainwater tank users rely on rainwater compared to the lagoon?
If the central lagoon is used as backup its filter needs to be upgraded anyway plus the new rainwater tanks with filters, then would this make the solution too broad because it considers harvesting and treatment?
