ABSTRACT
Urban Water Drainage Management involves the fields of water supply drainage, wastewater treatment and sludge handling. An efficient use of all the resources is important we have to use technology in such a way so that we can solve more problems faced by people living in urban areas. urban drainage planning and operation is aimed to ensure the public health and flood protection by completely collecting and quickly removing wastewater from the collected area, during both dry and monsoon season. As an “end of pipe strategy”, the wastewater treatment plant (WWTP) was dedicated to improving the receiving water quality, mainly during dry weather periods, by treating wastewater prior to its discharge, the sewer system was improved by increasing its collection efficiency and minimize the volume of combined sewer overflows (CSO). In many cases, this strategy provides insufficient and cost-ineffective protection of water, particularly in receiving waters. In many cases, this strategy provides insufficient and cost-ineffective protection of water resources. particularly of receiving waters. Reducing the CSO volume by storage causes an extended wet weather load on the WWTP, and may subsequently reduce its quality. Therefore. for optimum protection of the receiving waters. it is essential to take into consideration the loads from CSOs as well as from the WWTP effluent and relate them to the conditions in the receiving water. Depending on the site specific conditions, different pollutants or different dynamic characteristics may be controlling the receiving water quality. In the future urban drainage planning and operation should thus be guided by a site specific and problem-oriented approach. which requires extension of the system boundaries. The development of an appropriate strategy should be based on comprehensive analysis of the entire urban drainage system of areas lies in urban.
