摘要：The water cycle in nature is slowly changing through formation of towns and villages and consequent development of industrial centres and transport routes. Although cities are growing and changing, and their surface is increasingly modernised, underground sewerage networks have remained the same; old, insufficient and leaky. This contradiction troubles most cities in the world. Rainwater management is essential in urban areas, otherwise it can quickly become another form of wastewater with both organic and inorganic pollution. However, appropriate rainwater management will provide water retention for multiple water usage in towns and municipalities. Current water retention design options are discussed in this paper. Priority in designing water retention in urban areas must always be given to ground water infiltration at the point of rainwater origin. If this is impossible, rainwater should be diverted to the nearest suitable location for retention and later community use.
