Stormwater Management in Urban Areas by Combining Traditional and Alternative Techniques: If the Subdivision Mimosas in Marrakech

Abstract

The article presents more specifically how the stormwater management builds the overall plan and the problems that can be encountered during the implementation of improvements. With the growing waterproofing of cities and activity zones, the long rains or heavy rain storms, causing downstream flooding problems (or locally) as well as any shortfall in groundwater recharge underlying and disrupt the capacity of treatment plants and exceeds that of unit drainage systems of water, sustainable drainage system are tested in different countries. Better management and control of urban discharges during rainy weather is necessary, designing a alternative and integrated management model based on ecological engineering techniques, themselves adding value to natural purification and water filtration capacity allows not having to continually increase the capacity of the sewer systems, pipes and retention ponds hard, which are sources of technical, property, financial, environmental, social, legal, security and future maintenance costs.
