Review catchment, first flush, tanks, treatment, pumps, overflow, maintenance and permitted uses.
Stored rainwater is a system, not free capacity
Map roof catchments, gutters, leaf screens, first-flush devices, tanks, pumps, filters, disinfection, labels and every outlet. Confirm that overflow discharges safely without affecting foundations, slopes, neighbours or public drainage. Separate potable and non-potable lines clearly.
Request tank-cleaning, water-test, pump-service and repair records. Model usefulness against household demand and dry periods without promising savings. Read the villa water guide, drainage checks and management service.
