DESIGN OF A STORMWATER DRAINAGE SYSTEM FOR NGONG TOWN

Ngong town is located at the foot of Ngong hills where the structures are mostly developed. Due to this, Ngong experiences high levels of surface runoff. The negative effects of surface runoff have been experienced for a long time by the residents in various aspects, including economically. The rapidly increasing developments are increasing the impervious area in the town, thus worsening these effects.
This project studies the effects of surface runoff and will develop a stormwater drainage system which will aim to properly channel the runoff in the town. The first design phase will be to determine the runoff potential of the catchment area. This will be done using Google Earth and GIS softwares which will capture the potential catchment surfaces. Calculation of the amount of runoff that can be harvested from these surfaces will then be done to size the conveyance channels for the stormwater drainage system.
This project is a contribution to the efforts in integrated stormwater management that is emerging as a solution to minimize the effects of surface runoff in towns and cities.
