What is specific about Dammam for high water bill

The centre of Dammam sits about 12 m above sea level (SRTM open elevation data). Dammam is about 4.3 km from the sea coast (OpenStreetMap).

Team note on Dammam: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins..

The centre of Dammam sits about 12 m above sea level, according to SRTM open elevation data, and the city is about 4.3 km from the sea coast. Both facts shape how water moves and is stored in local buildings. Because the ground is only slightly above the sea, the pressure supplied to upper floors can be modest, so many schools rely on rooftop or ground-level storage tanks that are filled and then pumped. Being close to the coast also means the air is humid and salty, which can speed corrosion on exposed tank surfaces, fittings and float valves. Together these conditions mean that a school's water system works harder than its size alone would suggest.

Those conditions have practical effects on the bill. A tank that is poorly sealed or has a worn internal coating can let water seep into the structure and be lost before it reaches a tap, while corroded float valves may keep the tank overflowing without anyone noticing. Schools with a large number of outlets and sports facilities draw heavily at break times, so pumps cycle more often and losses from leaks become harder to spot. Internal tank coating is typically priced at SAR 25–60 per m², so repairing a coating is often far cheaper than paying for water that escapes through a damaged surface. Checking tanks, valves and pipe joints on a regular schedule is therefore a sensible way to control the cost of supply.

Owners of school buildings commonly make a few avoidable mistakes. Many assume a high bill must come from higher usage and never inspect the tank for overflow or leakage. Others delay replacing a faulty float valve because it seems minor, or they wait until a visible leak appears before looking at the coating underneath. Some also overlook outdoor taps, irrigation lines and staff washrooms, where a small continuous drip can add up across a term. Keeping a simple record of monthly readings, comparing them with term-time and holiday periods, and asking for a tank inspection whenever consumption jumps will help a school catch these problems early.

For schools, the larger jobs are planned for weekends and holidays.

Signs worth paying attention to

The following signs are worth checking before they grow:

• A sudden jump in the bill without a clear reason
• The meter moves at night
• The tank fills more often than before

Where the problem usually comes from

• A float valve that does not close.
• A silent leak in the network — we check this before anything else.
• A leaking toilet cistern.

Tools we use in Dammam

The steps in order

1. Two meter readings: Readings are taken with all use stopped, some time apart.
2. Cisterns and float valve: The usual silent causes are checked first.
3. Instrument survey: If the loss continues, the network is surveyed with instruments.
4. Report: You receive the readings in writing.
