Storm-drain network design in Anjafa
Storm-drain network design in Anjafa calculates runoff from roofs and roads based on local rainfall intensity and natural ground elevation. We route the network from high collection points to pumping stations or infiltration trenches with grades and pipe sizes approved by municipality.

What sets this area apart
Anjafa is a medium-density residential district of villas and apartment blocks on plots 30 to 50 metres deep with natural elevation sloping north. Most roofs and yards drain toward the street, and older networks in central sectors cannot handle winter rainfall. We calculate the actual drainage area for each property or block and size the pipes to the natural grade and required outlet elevation to prevent ponding on roads.
Anjafa sits in Hawalli governorate, a residential district with natural elevation sloping north where network design must be precise to avoid trapped water.
Network design requires a minimum gradient of 0.3 percent to ensure water flow in main pipes.

Questions about Storm-drain network design in Anjafa
Call nowHow do you calculate pipe sizes for each segment of the network?
We sum the drainage areas from all roofs, yards and roads in each zone, multiply by the design rainfall rate, then select pipe diameter that conveys that flow without stress.
Can natural ground slope be used to direct water without pipes?
In Anjafa yes, but only for open outdoor areas with sufficient slope. However, a designed pipe network ensures reliable flow even beneath flat roofs and courtyards.
