I am building a house with a reputable builder in Melbourne Western suburb.
We want to save water so we paid almost $900 for rainwater catchment system to our builder.
We got that price because it doesn't include water tank.
We assume that with that amount, the catchment system will connect to all the toilets.
But we are told that it is only for water catchment point.
What does rainwater catchment point mean and it is reasonable to cost that much for a catchment point?
