Town Tools builds free, public tools for Beirut 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.

Drinking water is a separate line
The tank and trucked water are brackish — fine for washing, cleaning and the toilet, but not for drinking. Keep the refill jugs for drinking and cooking, and use this planner for everything else.
The toilet is the biggest single draw
A full flush is 6–9 litres, several times a day per person. A half-flush, or a filled bottle set in the cistern, saves more water faster than anything else in the home.
Catch the state fill
When the mains water comes, make sure the pump fills the roof tank right up. A tank left half-full is days you'll end up paying a truck to replace.
In Beirut the state water reaches most homes only about every three days, so a household lives off what its tanks hold — the rooftop tank, and the ground tank under the building — and calls a truck to top up when that runs short. Put in how much water you have stored now, how many people it has to cover, and how carefully you're using it, and this works out how many days it lasts, whether it reaches the next state fill, and what a truck top-up would cost.
Nothing is saved and nothing is sent; the sum stays in your browser. The tank and trucked water are brackish — keep drinking water separate.
These are estimates
These are estimates from typical per-person figures. Real use swings with the household, the season and the day — a laundry day, a guest, or a hot week all move it. Your own tank and habits are the truth; treat the days here as a rough runway, not a countdown.
The delivery interval is typical, not a schedule
The state supply reaching Beirut homes about every three days is typical, not a timetable — it varies by neighbourhood and building, and thins badly in summer, when Greater Beirut can drop to only two or three hours of mains water a day. In a dry spell, plan for the gap to be longer than three days.
This is arithmetic, not health advice
This tool does the arithmetic and uses published per-person water figures; it is not advice on drinking-water safety or health. Stored or tanker water may need treatment before drinking — follow official guidance.
Who to call
For the state supply, billing, or a main that's dry when it shouldn't be, the Beirut & Mount Lebanon Water Establishment (EBML) is the authority — reachable on 1713. For what neighbours are paying for a truck right now, the price board on this site tracks the going rate.
