Why do Dubai villas run out of water?
A villa’s taps are fed from storage, not straight from the mains. DEWA water fills an underground tank through a float valve; a booster pump lifts it to a rooftop tank; gravity does the rest. When any link breaks, the house runs dry:
- DEWA supply cut — planned network work or a fault in the area.
- Low mains pressure — the underground tank can’t refill overnight, especially at peak times in summer.
- Burst or leaking pipe — the stored water drains before the repair is done.
- Tank cleaning — the tank is emptied on purpose and needs refilling the same day.
- New villa, no DEWA connection yet — the house is handed over before mains water is connected.
Underground tank or rooftop tank: which one do we fill?
In almost every villa, the tanker fills the underground tank through its inlet or access cover. From there your pump moves water to the roof as usual. If your villa only has a rooftop tank, or the underground tank is hard to reach, tell us before we dispatch so we can plan hose length and access.
How big is a villa water tank?
It varies from villa to villa, so we don’t quote a “standard” size. The reliable way is to check the tank’s label or measure it: inside length × width × height (in metres) × 264 = US gallons. A tank measuring 2.5 × 2 × 1.5 m holds about 1,980 gallons. Order the difference between that and what is already inside — never more than the tank can take.
What to check in the first ten minutes
- Call DEWA on 991 or check the DEWA app for outages.
- Look at the underground tank level. Empty tank = supply problem → tanker. Full tank but dry taps = pump or valve problem → plumber.
- Turn the pump off if the tank is empty, so it doesn’t run dry and burn out.
