Angle: A real installed cost for a home RWH system, using the ~790mm NCR rainfall figure.
This guide must answer: - What does a home recharge/storage system cost? - What drives the cost (plot size, pit vs tank)? - What can a home realistically harvest at ~790mm/yr? - Payback via water savings or just compliance?
Writing rules: answer the question in the first two sentences, put a real number in the opening paragraph, name the specific city or DISCOM where the answer varies, and link to two related guides and the relevant category page.
Verify before publishing: Local RWH installer prices; the 790mm rainfall figure is on record.
