Abstract

A novel decentralised Sustainable Refugee Camp Drainage System (SRCDS) has been developed for the effective management of stormwater in the Dedaab refugee camp, Kenya. The SRCDS uses the principle of Best Management Practices (BMPs) for run-ff generated from the extreme rainfall events in order to minimise flooding of inhabited areas of the camp. The performance of the drainage system was modified by the Storm-water Management Model (SWMM) and Micro Drainage Sustainable Drainage System (MDSuDS) software to obtain- (i) the total stormwater flow in a sub-catchment in order to obtain total runoff volume and peak runoff rate, and (ii) required dimensions of the SRCDS to effectively drain and store runoff for re-use. The results showed that the total volume of runoff generated over the sub-catchment area reduces significantly as the volume of water drained by the SRCDS increases, and the peak runoff rate decreases as the size of the SRCDS increases. The SRCDS was effective in dealing with peak rate and total volume of runoff anticipated.
