The dry-season water story in one place — where it comes from, why it runs short, and a live neighbour board of where the water is off right now.
About these tools
Town Tools builds free, public tools for Sa Pa and towns around the world. A team of agents researches each place from local sources and keeps the tools up to date; residents suggest new ones and report corrections.

Sa Pa's tap water runs short most dry seasons. The original town plant draws from four mountain sources — Thác Bạc, Suối Hồ 1, Suối Hồ 2 and Nhà Pha — and is licensed for about 6,460 m³ a day, but in the dry months only around 3,000 m³ actually reaches taps, against demand of 4,000–6,500 m³. A newer plant (the BOO plant, online since November 2022) added supply, yet shortages still hit.
When your water stops, the useful question is: is it just my tank, or is the whole area dry? Sign in and tap your area to tell your neighbours — and to see where others are reporting no water right now. Reports clear on their own after a few hours, so the board reflects now, not last week.
No water cuts reported right now.

These reports come from neighbours, not the water utility. Anyone can read the board; reporting no water takes a free account, which keeps it honest. A report clears itself after about 8 hours, so the board stays current on its own. When several people report the same sector, it’s likely the whole sector is dry — not just one tank.
Where Sa Pa's water comes from
The original plant, run by Lào Cai Water Supply, draws from four streams off the mountains — Thác Bạc, Suối Hồ 1, Suối Hồ 2 and Nhà Pha. Two of them (Nhà Pha and Suối Hồ 1) are largely depleted and the flow at Thác Bạc is falling. Experts blame declining groundwater together with around twenty upstream hydropower projects that hold water back in the dry season. The newer BOO Sa Pa plant (DNP Water), online since November 2022, draws from the Mường Hoa and Vàng streams and added roughly 7,500 m³ a day — but in peak dry spells supply still trails demand.
Dry-season supply ~3,000 m³/day against 4,000–6,500 m³/day of demand
The water utility — Lào Cai Water Supply (Công ty CP Cấp nước Lào Cai)
Runs the original Sa Pa plant and its four mountain sources. No public outage hotline was verifiable when this page was built — official cuts and notices are reported through Báo Lào Cai and the ward (phường Sa Pa) channels.
