Why is my water bill so high for a villa in Al Nkhyl, and could there be a leak? This is the first question many property owners ask when a monthly statement jumps without a clear reason. Al Nkhyl is a residential district on the northern side of Riyadh, centred near 24.7422, 46.6375, roughly 5 km from the city centre, with an approximate radius of 3.9 km. It is a mixed area with both villas and apartment buildings, so a high bill in one villa is not automatically a sign of a fault in the wider network. The centre of the district sits about 622 m above sea level, and the nearest wadi channel lies roughly 1.4 km away. Neither fact proves a problem on its own, but together they help explain why storage tanks and rooftop installations deserve a careful look.

When a technician visits a villa in this area, the inspection usually starts with the meter reading and the household's recent consumption pattern, followed by a walk through the internal plumbing to identify running toilets, dripping taps, and irrigation lines left on. The team then checks the ground-level and roof tanks, looking for overflow, seepage, or signs that water is escaping through a crack or a failed joint. If a tank shows wear, the inside surface may be assessed for protective coating condition. Tank internal coating is typically priced at SAR 25–65 per m², depending on the surface and the work required, so an accurate measurement of the tank is an important first step before any quotation is agreed.

To make the visit faster and more useful, prepare a copy of your last six bills if you have them, along with the meter number and any notes on when the increase began. Clear access to the roof, the tank area, and the garden irrigation valves will save time. Please also tell the technician about recent works in the villa, such as a new pump, a pool top-up, or a change in the number of residents. Keep a short log of who used water and when for a few days before the visit. This information lets the inspection focus on the likely causes instead of checking every fixture from scratch.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.

Signs that call for high water bill

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

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

Causes we see in the field

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

Tools and methods, and when we use them

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.
