Before we start: what we know about Al Mlz

The centre of Al Mlz is at 24.6561, 46.7275, about 8.3 km from the centre of Riyadh, with an approximate radius of 2.8 km. The service-area circle on the map below is drawn from this point. Main roads in or near Al Mlz: University Street, Salah al-Din al-Ayyubi Road, Omar bin al-Khattab Road.

High water bills in residential buildings in Al Mlz, Riyadh, usually start with a simple question: is the water actually leaving the building through a fixture, a tank, or a pipe, or is the bill simply reflecting normal use spread across many households? Al Mlz sits at about 24.6561, 46.7275, roughly 8.3 km from the centre of Riyadh, and it covers an approximate radius of 2.8 km. Because the area is mainly apartment buildings, many units share a single supply system, a rooftop or ground tank, and a common meter. That shared setup means a leak in a shared riser or tank can raise the bill for everyone, so the first checks focus on the common parts of the building before individual flats are examined.

The centre of Al Mlz sits about 592 m above sea level, according to SRTM open elevation data, and this matters for pressure and for how water moves through the building. Technicians therefore look first at the storage tank and its condition, since tank internal coating is priced at SAR 25–70 per m², which is a cost that can be weighed against the size of the tank once the problem is confirmed. Beyond that, the exact cause of a leak, the state of valves and float switches, the condition of hidden pipework, and whether a fixture is running continuously are all left to the site visit. These points depend on what is found on the day, so no fixed outcome is promised in advance.

To help the technician, residents and building managers should have a few details ready. Note the building's location in Al Mlz, the number of apartments served by the shared meter, and when the bill first rose compared with previous months. Mention where the tank is located and whether it is on the roof or at ground level, and say whether anyone has heard water running at night when all taps are closed. Share any recent plumbing work, the age of the building, and whether the common meter reading has changed. Clear information like this lets the visit focus on the likely source, saving time for everyone sharing the supply.

For a residential building, shared risers, tanks and pumps are checked as one system.

When do you need high water bill?

If you notice one of these signs in Al Mlz, 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

Causes we see in the field

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

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.
