High water bill for residential buildings in Jeddah

What is specific about Jeddah for high water bill

The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data). Jeddah is about 2 km from the sea coast (OpenStreetMap).

Team note on Jeddah: 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..

Jeddah sits on the Red Sea coast, and the centre of the city lies about 15 m above sea level. That elevation matters for water bills because residential buildings in low-lying parts of the city often rely on rooftop or elevated storage tanks that are filled by pumps. A pump working harder to lift water to a roof draws more power and runs longer, which can show up as a higher bill even when household use has not changed. Owners who notice a sudden jump should first check whether pump run times have increased, since a leaking float valve or a worn pump seal can cause the same effect.

The city is also about 2 km from the sea coast, which places most residential buildings close enough to the salt-laden air and warm climate that tanks and their fittings are exposed to heat and corrosion over time. Heat speeds up evaporation from open or poorly sealed storage and can accelerate deterioration of unprotected tank walls. Corrosion can create small leaks and rough surfaces where scale and bacteria collect. In practice, a tank with a damaged interior may lose water through seepage and force pumps to refill it more often. Inspecting the tank lid, overflow pipe and inside walls during routine checks helps catch these problems before they grow.

Several common mistakes add to high water bills in these buildings, and owners who avoid them usually keep costs under control. Many leave a tank uncoated or let an old coating break down, then ignore the cost of restoring it; a proper internal coating typically costs SAR 25–65 per m², which is often far less than the cumulative loss from leakage and extra pumping. Others wait until the bill arrives to act instead of tracking meter readings each month, which makes a slow leak hard to spot. Some also overlook float valves, fail to clean sediment from the tank bottom, or assume a higher bill must come from the utility rather than from their own system. Checking the building's tanks, pumps and fittings on a regular schedule is the simplest way to keep the bill predictable.

For a whole building, a survey of the shared systems comes before unit-by-unit work.

Signs worth paying attention to

These are the signs most often linked to high water bill:

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

Causes we see in the field

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

Tools and methods, and when we use them

From the first visit to the report

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.

The written outputs

The written output: a report with the readings to support your follow-up on the bill. The report is numbered and can be checked with its verification code.
