What is specific about Alysha for underground tank leak detection

The centre of Alysha is at 24.6308, 46.6842, about 9.2 km from the centre of Riyadh, with an approximate radius of 1.2 km. The approximate area shown on the map is centred here. The nearest wadi channel is about 1.2 km from the centre of Alysha (OpenStreetMap).

Alysha sits at 24.6308, 46.6842, roughly 9.2 km from the centre of Riyadh, and its built-up area has an approximate radius of 1.2 km. That compact footprint means most rest houses and farms here are close to one another and to the main road network, which makes it practical for a technician to reach several properties in one visit. Because the centre of Alysha sits about 604 m above sea level, the ground and the water tables beneath it behave differently from those on lower land, so tank assessments here should always consider the local groundwater conditions rather than relying on a generic checklist.

The nearest wadi channel is about 1.2 km from the centre of Alysha, which is a fact that shapes how we approach leak detection. Wadi courses carry seasonal runoff, and soil near them can shift in moisture levels after rain, which can mask or mimic the signs of a leaking underground tank. We therefore check the surrounding ground, the tank's position relative to slopes and drainage lines, and the readings from the tank itself before drawing any conclusion. For owners, the practical effect is that a test performed after a heavy rain should be interpreted with care, and a second check is often worth arranging once the ground has settled.

When an underground tank needs repair or restoration, the internal coating is often part of the discussion, and it is priced per square metre at SAR 25–70 per m². The actual range depends on the tank's size, its condition and the access available, so we confirm the measurements on site before quoting. Owners of rest houses and farms in Alysha commonly avoid a few mistakes: they delay a check until the water loss is obvious, they ignore changes in their monthly water usage, they dig or excavate without a clear survey of the tank's position, and they accept a repair without asking what the coating covers. Keeping a simple record of consumption and inspecting the tank on a regular schedule helps catch problems early and keeps the decision in the owner's hands.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

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
• A noticeable drop in the water level overnight

Where the problem usually comes from

• Cracks in the concrete tank walls or floor.
• Construction joints and corners — we check this before anything else.
• A float valve that does not close, so water is wasted.

How we choose the tool in Alysha

The steps in order

1. Safety first: Tank lids and confined spaces are handled with ventilation and a second person on site.
2. Documented level test: Filling and use are stopped and the level is recorded against time.
3. Isolating the tank from the network: This tells us whether the loss is from the tank body or from the supply line.
4. Checking the body and connections: Inlet, outlet and overflow connections are inspected.
5. Recommendation: You get the next step in writing: repair, waterproofing or a line test.
