摘要

Water is an important component of the urban environment, and principally appears in cities and towns in the form of drinking water, wastewater, storm-water, natural water bodies and artificial water bodies and features in open spaces. Features of the built environment interrupt the natural cycle of precipitation, infiltration, surface runoff and evaporation, with serious implications on the urban climate. Water in the urban area cannot infiltrate into the ground due to paved surfaces, but is rapidly discharged to the public drainage systems, with little time to evaporate. As a result, groundwater recharge is grossly minimised. Furthermore, the water is highly polluted, and so negatively impacts on the qualitative and quantitative state of the receiving water. Historically, storm-water management, which is dominated by engineers, has been the main discipline at the centre of solving these problems.
