Abstract

In this research, a new decentralised drainage system, Sustainable Refugee Camp Drainage System (SRCDS), is developed for effective management of storm water and greywater in Dadaab refugee camp, Kenya. The SRCDS uses the principle of Best Management Practices (BMPs) to manage storm water and greywater point sources before they can mix. The numerical modelling of the drainage system was undertaken using the Storm Water Management Model (SWMM) and Micro Drainage Sustainable Drainage Systems (MDSuDS) software packages. The numerical modelling of the drainage system was carried out in two main stages (i) the total storm water flow in a sub-catchment in order to obtain total runoff volume and peak runoff rate and (ii) to obtain required dimensions of the SRCDS required to drain and store the generated runoff for reuse. The results obtained showed that (i) the total volume of runoff generated over the sub-catchment area reduces significantly as the volume of water drained by the SRCDS increases and (ii) the peak runoff rate decreases as the sizes of the SRCDS increases. The sizes of the SRCDS were iteratively modified until adequate sizes to cope with the peak runoff rate and total runoff were achieved.
