Al Nrjs is mainly villas.

Al Nrjs sits at roughly 24.8341 N, 46.6802 E, about 13.4 km from the centre of Riyadh, and its centre lies around 648 m above sea level. Because the neighbourhood is mainly villas, a high water bill at a duplex here is usually approached as a question of how the building's own supply and storage behave, not as a neighbourhood-wide problem. Our technicians therefore begin with the basics that are easy to confirm from the outside: whether the meter is still turning when every tap is closed, whether the overhead or roof tank overflows or refills more often than the household uses it, and whether any tap, toilet cistern, or outdoor line is dripping. A running meter with no visible use points to a leak somewhere on the private side of the connection, and that is where we look first.

Several things cannot be settled from a description and are left to the site visit. The technician will open the tank lid, check the float valve and the overflow pipe, and listen along the pipe runs for hidden leaks in walls or under floors. Pressure, pump cycling, and whether the two units of a duplex share a single meter or tank are also judged on site. Any figure for tank lining is only a rough guide until the tank has been measured: the internal coating for a tank is quoted at SAR 25–65 per m², and the final area depends on the tank's actual size and condition, which the visit establishes. We will not assume a fault until it has been seen.

To help the technician arrive prepared, it is useful to have the previous few bills to hand, a note of when the high readings began, and any recent work on the plumbing, pump, or roof. Please also say whether the duplex is fed from a street connection or a rooftop tank, and whether there is a wadi channel nearby, since the nearest one lies about 0.7 km from the centre of Al Nrjs. Knowing which units are occupied and at what times helps us separate normal use from waste. Keep the meter reading and the time you took it, and leave access to the roof and tank area clear. With that information, the visit can move straight to the checks that matter most.

In a duplex, the two floors often share lines, so tests are done floor by floor.

When do you need high water bill?

The following signs are worth checking before they grow:

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

Causes we see in the field

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

How we choose the tool in Al Nrjs

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.
