Site level survey
Ground elevation readings confirm the natural direction water will travel

Farwaniya
Storm-drain design in Ardhiya Industrial starts with a full site survey to map roof heights and paved areas across warehouses and workshops. We lay out primary and secondary pipe routes, locate sump pits and final discharge points and size each segment for winter downpours. The design ensures fast water clearance before pooling threatens stock or equipment.
Warehouses and factories across Ardhiya Industrial have wide flat roofs and concrete floors that shed water poorly. Most buildings stand tall and the paved yard around each facility slopes gently outward to its perimeter. We design a network that captures roof runoff through metal downpipes into subsurface collection pits, then primary drainage lines that carry the flow off-site or into a deep sump.
Ardhiya Industrial lies in Farwaniya governorate, a zone wholly devoted to warehouses and factories where vast roof areas and large paved expanses dominate the landscape.
Every line is tested under full flow pump to verify drainage rate and detect blockages before the project is handed over.
Ground elevation readings confirm the natural direction water will travel
Expected flow volume determines the correct pipe diameter for each run
Gullies are positioned so no low point is left without an outlet
Chambers placed at every direction change to allow future maintenance
Adequate slope prevents sand settlement and keeps flow gravity-driven
Final discharge point set away from foundations, fencing and neighbouring plots
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.

We divide the roof into multiple collection zones, each with separate downpipes feeding intermediate pits nearby. These pits then connect to one large main line that pulls water away fast before any buildup occurs.
It depends on soil type and groundwater levels under the site. We sample soil at three points to measure absorption rate, and if it is slow we design a deep sump pit instead of surface discharge.
