High water bill in Al Zhra: the local context

The centre of Al Zhra is at 24.5755, 46.6455, about 15.7 km from the centre of Riyadh, with an approximate radius of 1.2 km. The service-area circle on the map below is drawn from this point. The centre of Al Zhra sits about 676 m above sea level (SRTM open elevation data).

The nearest wadi channel is about 1.6 km from the centre of Al Zhra (OpenStreetMap). Main roads in or near Al Zhra: Hamza bin Abdul Muttalib Street, Sheikh Abdulrahman bin Furyan Street, Sheikh Ishaq bin Abdulrahman bin Hassan Street.

A sudden jump in your water bill usually points to a leak somewhere between the meter and your taps, and in a home this is the most common cause we see. Dripping toilet cisterns, a running valve on a rooftop tank, or a hidden break in a buried supply line can quietly use a large volume of water before anyone notices a wet patch. In Al Zhra, the first check is always the meter: switch off every tap and appliance, note the reading, and see whether it keeps moving. If it does, the leak is in the system and needs a professional eye rather than a guess.

Al Zhra sits at about 24.5755, 46.6455, roughly 15.7 km from the centre of Riyadh, with an approximate radius of 1.2 km. It stands about 676 m above sea level, so the building and any rooftop tanks are working against local pressure conditions that differ from lower-lying parts of the city. The nearest wadi channel lies about 1.6 km from the centre, which matters because ground conditions and drainage can affect where a buried line runs and how it is affected after heavy rain. Tank condition also matters here: internal coating for a water tank is priced at SAR 25–65 per m², so an older tank with a failing lining can leak or contaminate supply, and it is worth asking whether the tank itself has been inspected as part of the visit.

Before the technician arrives, ask a few direct questions. Ask whether they will read and record your meter both before and after the test, so the leak can be confirmed with figures rather than impressions. Ask whether they check the rooftop or ground tanks, the cisterns, and the buried supply line, and whether they will tell you the cost of any tank coating work in advance using the SAR 25–65 per m² range. Finally, ask what they will do with any damage to floors or walls, and how quickly the leak can be stopped so your next bill starts coming down.

If water is flowing, close the main valve first, then call or message with photos.

Signs worth paying attention to

The following signs are worth checking before they grow:

• 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 — we check this before anything else.
• A silent leak in the network.
• A common cause: a leaking toilet cistern.

Tools and methods, and when we use them

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.
