A wider scope for construction of a drainage system provisions in the Pourashava. At least central area proposes as open for such development immediately and other areas will follow for project period as designs in the plan. The Pourashava still stands as barren field for introducing drainage system. The principles need for drainage plan available in the area. Land slope, nearness of the natural drainage, sparse population density and soil condition shows in favour of drainage construction.
Drainage corridors
If a drainage network installs, the drainage originates throughout the Pourashava create surface drains and culverts. These will accommodate within road reserves.
General location required
For sewerage treatment plant, needs large plot, preferably on outskirts of the Pourashava. For sewerage pumping station, needs small plots throughout the Pourashava and introduces a system.
Maintaining of land slope
Important component of the drainage network identifies land slope, not maintains during the construction of existing drains. The slope of the Pourashava towards east and southeast. Slope of all drains maintain this direction.
