Underground tank leak checks in Al Mwnsya, Riyadh, start with the location itself. The centre of Al Mwnsya sits at 24.8312, 46.7683, about 16.1 km from the centre of Riyadh, with an approximate radius of 1.2 km, so most properties here are a reasonable distance from the city core and may rely on tanks that have been in place for some time. The ground stands about 608 m above sea level (SRTM open elevation data), which means the technician will look closely at how water and fuel pressure behave on site. The nearest wadi channel is about 2.9 km from the centre of Al Mwnsya (OpenStreetMap), so the first questions concern drainage paths, soil movement after rain, and whether any nearby low ground could carry seepage.
Several things cannot be settled from a description and are left to the site visit. The technician needs to see the tank itself, its age, its access points and the condition of the pipework leading to pumps and buildings. Soil type around the tank, the water table depth, and any signs of staining or wet patches at the surface can only be judged on the spot. If internal lining work is recommended, the price is set after measurement, since internal coating is quoted at SAR 25–65 per m², and the final area depends on the tank's actual size and condition. Whether a repair or a full replacement is the better route also depends on what the visit reveals.
To help the technician arrive prepared, it is useful to have the tank's installation date, any previous repair records, and the usual fuel or water volumes drawn from the tank. Note any recent changes in meter readings, unexplained drops in stock, or unusual smells near the ground. Clear access to the fill cap, the inspection chamber and the pump area saves time, and a note of where the tank sits relative to buildings, boundary walls and the drainage direction on your plot will help the visit run smoothly. Keep the property plan handy, as it shows where the tank lies and how it relates to the wider site.
The aim is to locate the cause with instruments first, so any opening is limited to one point.
When do you need underground tank leak detection?
These are the signs most often linked to underground tank leak detection:
- A noticeable drop in the water level overnight
- The pump runs for longer periods
- The tank needs refilling faster than usual
- Damp or salt marks on the tiles above the tank
The most common causes
- A common cause: a float valve that does not close, so water is wasted.
- A common cause: construction joints and corners.
- Cracks in the concrete tank walls or floor.
Tools and methods, and when we use them
| Tool | What it finds | When we use it in Al Mwnsya |
|---|---|---|
| Documented tank level test | Level drop in numbers against time | Limits: filling and use must stop for a while |
| Pressure test and line isolation | Which line (hot/cold, floor by floor) loses pressure | Limits: needs working valves to isolate lines |
| Moisture meter | How far the wet area spreads behind paint and tiles | Limits: measures the effect, not the source |
| Ground microphone and contact listening | The sound of water escaping under pressure in walls and floors | Limits: weaker with background noise and deep lines |
The steps in order
- Safety first: Tank lids and confined spaces are handled with ventilation and a second person on site.
- Documented level test: Filling and use are stopped and the level is recorded against time.
- Isolating the tank from the network: This tells us whether the loss is from the tank body or from the supply line.
- Checking the body and connections: Inlet, outlet and overflow connections are inspected.
- Recommendation: You get the next step in writing: repair, waterproofing or a line test.
