Imagine a family that owns a duplex in Alysha, with one unit rented to tenants and the owner living in the other. One month the water bill arrives far higher than usual, and nobody in the building remembers running taps or filling tanks more than normal. The owner wonders whether a leak is hiding somewhere in the pipes, whether the rooftop tank is overflowing, or whether the meter itself is wrong. Duplexes share plumbing in ways that make these questions harder to answer, because one shared tank or one shared line can serve two households at once.

Alysha sits at 24.6308, 46.6842, roughly 9.2 km from the centre of Riyadh, with an approximate radius of 1.2 km. Its centre rises about 604 m above sea level, which means gravity and pressure in the local network are shaped by the terrain, so pressure differences between buildings can affect how water flows into rooftop tanks. The nearest wadi channel lies about 1.2 km from the centre, a reminder that storm runoff and ground conditions matter here. For a duplex owner, these facts suggest that water use should be checked against the actual supply setup and not assumed to be normal.

Start by reading the meter on both units on the same day each week, so you can see which household or line is drawing more water. Next, check the tank and its float valve for overflow, and look for damp patches on walls or ground that suggest a hidden leak. If the tank is old, get a quote for internal coating, which typically falls in the range of SAR 25–65 per m², and compare it with the cost of repeated losses. Finally, keep a simple log of readings and repairs, so that any future bill can be traced to a specific cause.

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

Signs worth paying attention to

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

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

Causes we see in the field

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

How we choose the tool in Alysha

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.
