High water bill in Dammam: before buying or handover

Before we start: what we know about Dammam

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.. Dammam is about 4.3 km from the sea coast (OpenStreetMap).

The centre of Dammam sits about 12 m above sea level (SRTM open elevation data).

Dammam sits on the Gulf coast of Saudi Arabia, and the centre of the city lies about 12 m above sea level according to SRTM open elevation data. That is a modest height, but it shapes how water moves through the network. Buildings in the centre draw from a supply that must be pushed upward, so household pressure can vary from floor to floor. When a high water bill appears, owners often look first at tariffs, but pressure-driven overflow from roof tanks and leaking fittings can also quietly add litres each day. Checking the float valve and the overflow pipe is a practical first step before assuming the meter is wrong.

Dammam is also about 4.3 km from the sea coast, as measured in OpenStreetMap. This closeness brings salt-laden air and humidity, which speed up corrosion on metal fittings, tank lids and exposed pipe joints. Over time, a weakened joint or a cracked seal near the tank can leak without any visible pool of water, and the loss shows up only on the bill. Because the coastal air is damp, owners should inspect outdoor tanks, valves and connections at each handover or after any renovation. Where a tank's interior has deteriorated, coating work is an option, and the figure for internal tank coating is SAR 25–60 per m². The total depends on tank size and access, so a site check is needed before any quote is accepted.

Owners who handle high water bills well tend to avoid a few common mistakes. They do not ignore a slow rise in consumption, because a small leak running for weeks adds up. They do not assume a new tenant has caused the increase before checking fittings. They do not skip inspecting the roof tank during a property purchase, and they do not accept verbal assurances about the tank's condition without seeing the interior. Keeping a simple monthly record of meter readings makes any change visible early, and it gives a clear reference point when speaking to the supplier or a technician.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.

Signs that call for high water bill

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

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

Where the problem usually comes from

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

Tools we use in Dammam

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.
