An integrated approach to water management in Kayseri: rainwater collection and use in an amusement park.

Water management in urban areas of developing countries is a major environmental challenge for the future. Within the framework of the IWA Cities of the Future Programme, current water and wastewater management systems are investigated in Kayseri, Turkey, with the purpose of bringing water into the center of city life by a reformed pilot project. In order to assess both the quantity and dynamics of water to be utilized in the Kayseri Amusement Park, the US Environmental Protection Agency's (US EPA) Storm Water Management Model (SWMM) 5.0 was used. The obtained results demonstrated that after 3 years, 38,039 m(3) of rainwater could be stored in the two proposed underground storage tanks. Forty three per cent of the water-ski lake with a volume of 90,000 m(3) could be recharged with the stored rainwater.
