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.
Next step
Phuket Stay Pro can document the water system and maintenance plan.
Fact check
Water quality, permitted use, treatment, rainfall, storage performance, drainage and costs vary by property and date. Test water and obtain current local technical and authority advice.
Compare properties before you buy
Start with the location and buying goal. Compare handover dates, ownership options and payment terms; confirm the current price and availability for the selected unit.
