Site and depth planning
Position and depth chosen to suit the transfer pump and surface loads

Farwaniya
Underground tank construction in Hassawi starts with deep excavation into sandy soil to accommodate the required storage volume. We pour reinforced concrete walls, seal the top surface with waterproof membrane, and pressure-test the entire structure. Supply, overflow and drain pipes are then connected and flushed. The tank is ready for immediate service.
Hassawi houses are medium-rise with flat roofs and varied roof-tank sizes, but an underground tank provides crucial summer backup during the long season. We dig beside the house where distance from boundary walls and existing pipes allows. Sandy soil requires water management during excavation to prevent wall collapse. We leave air space above the tank for ventilation and an accessible inspection cover.
Hassawi is in Farwaniya governorate, a growing residential area where most houses rely on the public mains supply supplemented by roof tanks.
Before handover the tank is filled completely and monitored under pressure for two hours to confirm every joint is watertight.
Position and depth chosen to suit the transfer pump and surface loads
Base and walls built to carry soil pressure and full water load
Internal and external coating layers that block water movement in both directions
Inlet and outlet openings sealed with rubber collars to prevent pipe-joint leaks
Transfer pump and water-level float wired and adjusted for correct operation
Tank filled and water level watched to confirm zero leakage before backfilling
How we work

Tell us what is happening and where, and the right equipment is loaded before we arrive.

We film the line from inside and know the kind of blockage and its exact place. No guessing.

High pressure water, a machine or a drain snake, whichever the line actually needs.

The camera runs a second pass and you see the line clear with your own eyes before we leave.
Same method, same equipment. Only the size of the job changes.




Why us
Amana means trust. Someone else's home is not ours to be careless in.
Do not take our word for it. Look at the line yourself.
Breaking is the last resort, never the first step.
A blocked line does not wait for the morning.
Six governorates, 139 areas.
For buildings and complexes, servicing before the problem starts.
Restaurants, offices and complexes, not only homes.

Yes, but we must measure the yard and locate underground pipes first. If pipes are too close we reposition the tank or use a taller narrower design for the same volume.
Depth depends on tank size and expected groundwater level. Hassawi usually requires one-and-a-half to three metres depth. We test the soil first to avoid digging below the water table.
