Infrastructure Compliant Stormwater Management (ICSM) strategy is an approach where stormwater runoff volume above the capacity of existing drainage systems can be managed using Water Sensitive Urban Design (WSUD) technologies. This new approach could support the growth needed in urban landscapes of developing countries in Asia. A trial catchment in Dhaka, Bangladesh was considered to examine feasibility of the ICSM strategy. An essential element of ICSM strategy was the assumption that the existing stormwater drainage infrastructure of Dhaka City has a capacity limit equivalent to 1 year ARI rainfall events. Rainfall beyond this capacity is responsible for serious flooding; it can be successfully managed by employing infiltration based WSUD technologies. The study showed that with infiltration based WSUD technologies in place, an acceptable level of nuisance flooding will only be experienced in 100 years rainfall events. Also complete flood security using the same WSUD technologies at the 50 and 20 years levels can be provided through the ICSM strategy. The approach explained in this study can be an effective solution of everyday problems for stormwater quantity control in residential areas of Dhaka City and other developing countries in Asia with similar geo-environmental conditions and urban growths.
