High water bill in Jeddah: the local context

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.. 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).

Water bills at offices and commercial complexes in Jeddah often climb for reasons that have little to do with how many people use the taps. The most common culprit is a leak or overflow in storage tanks and the pipework that feeds them, which can run unnoticed for weeks in large buildings where no single person is responsible for checking the roof tanks or basement reservoirs. Toilets with faulty flush valves, cooling systems that lose water through bleed-off, and irrigation timers left running for landscaped areas are other frequent sources. For a commercial property, the first step is usually to compare the current bill against the same period last year and then walk the building to find where the water is actually going.

Local conditions shape how that inspection should be planned. The centre of Jeddah sits about 15 m above sea level, which means buildings in the city centre generally rely on pumps to lift water to upper floors and rooftop tanks, so pump run-times and float valves deserve close attention. Jeddah is about 2 km from the sea coast, a distance that brings salty air and humidity into the area and can speed corrosion on metal tank fittings, valves and exposed pipework. A technician working in Jeddah should therefore check tank linings and fittings for deterioration, not only the visible plumbing. Where tank coatings are part of the repair, internal coating is priced at SAR 25–65 per m², so the scope of the tank surface needs to be measured before the job is quoted.

Before the visit, ask the service provider a few clear questions. Find out whether the inspection covers rooftop tanks, ground reservoirs, cooling water loops and irrigation lines, and whether the technician will test pump operation and float valves rather than only reviewing the pipes. Ask how the tank surface will be measured, what the internal coating rate is per m², and whether that rate applies to your tank size. Request a written list of what will be checked, what will be repaired on the day, and what will need separate approval. Finally, ask who on your team should be present during the visit so that any hidden leaks can be pointed out and the findings explained clearly.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.

Signs worth paying attention to

If you notice one of these signs in Jeddah, it is a good moment to talk to the team:

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

Causes we see in the field

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

How we choose the tool in Jeddah

How the work is done, step by step

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.

Mistakes that cost more

• Waiting for the next bill instead of testing the meter

What you get after the work

You receive: a report with the readings to support your follow-up on the bill, in a technical report with a verification code.
