Underground tank leak detection in Mnfwha, Riyadh: before summer & rain season
In short: In Mnfwha (Riyadh), underground tank leak detection (before summer & rain season) begins with the documented tank level test and the pressure test and line isolation; nothing is opened until the position is clear. The centre of Mnfwha sits about 580 m above sea level (SRTM open elevation data). Published price: Inspection visit, SAR 150 per visit; anything else is quoted after the inspection.

Underground tanks in Mnfwha, Riyadh, most often run into the same problem: a slow leak that goes unnoticed for months because the water level drops only a little each day. Many buildings in Mnfwha have been in use for decades, so the tanks serving them may be old, with corroded walls, cracked joints or failing inlet and outlet pipes. A small leak can still waste a lot of water and can seep into the ground around the building, so it is worth checking before the hot season puts extra pressure on the supply.
The local setting changes how we approach the job. The centre of Mnfwha sits about 580 m above sea level (SRTM open elevation data), and the nearest wadi channel is about 1.7 km from the centre of Mnfwha (OpenStreetMap). Parts of Mnfwha lie along a wadi or flood path, so the ground around a tank may be wetter after heavy rain, and that moisture can hide or mimic a leak. We therefore look at the surrounding ground and the tank's position as well as the tank itself. Where a tank may be affected, the internal coating is a common repair, priced at SAR 25–65 per m² depending on the work needed. The exact cost depends on the size and condition of the tank, and we only quote after the inspection.
Before the visit, ask the following. Confirm the tank's age, its size, and whether it has been repaired before. Ask whether the building sits near a low point or a flood path, and whether water has ever pooled near the tank after rain. Ask what the inspection covers, how long it will take, and whether you will receive a written report of what was found and what is recommended. Finally, ask how the work will be scheduled so that your water supply is not cut off for longer than necessary. Clear answers to these questions will help you decide on the right step for your property in Mnfwha, Riyadh.
Checks before summer and before the rain season catch problems while they are still small.
When do you need underground tank leak detection?
The following signs are worth checking before they grow:
- Damp or salt marks on the tiles above the tank
- The tank needs refilling faster than usual
- The pump runs for longer periods
Causes we see in the field
- Cracks in the concrete tank walls or floor.
- A common cause: construction joints and corners.
- A float valve that does not close, so water is wasted — we check this before anything else.
How we choose the tool in Mnfwha
| Tool | What it finds | When we use it in Mnfwha |
|---|---|---|
| Ground microphone and contact listening | The sound of water escaping under pressure in walls and floors | To trace undocumented lines in the older buildings of Mnfwha |
| Moisture meter | How far the wet area spreads behind paint and tiles | Limits: measures the effect, not the source |
| Pressure test and line isolation | Which line (hot/cold, floor by floor) loses pressure | Limits: needs working valves to isolate lines |
| Documented tank level test | Level drop in numbers against time | Limits: filling and use must stop for a while |
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.
