The Garang River functions as a flood controller and a source of raw water for drinking water. This river is divided into seven segments, and in the downstream segment VI there is intake of raw water for drinking water. The land use is dominated by built-in land, in the form of dense settlements and industrial estates. This study aims to evaluate the condition of the drainage system, both in terms of runoff and water quality, and apply the concept of LID to achieve a sustainable drainage system. The method used is the SWMM. Evaluations were carried out in three outlets. In existing conditions, channel capacity in general is still sufficient, while water quality does not meet effluent standard quality for observed parameters including TSS, BOD, COD, oil & fat parameters and Total coliform. The LID concept that are suitable are Bio retention cell, Permeable Pavement and Rooftop disconnection.The use of this type of LID is significant enough to reduce runoff by 77% at outlet 1, 98% at outlet 2 and 73% at outlet 3 and decrease in some parameters of water quality by 77% to 100%.

Wastewater systems are of crucial importance to the promotion of sustainable development. Through an integrated planning approach, the costs can be minimized and the resulting benefits maximized. A planning approach at regional level exploits the economies of scale, while achieving a better environmental performance. In this paper we set out a decision support approach for the planning of regional wastewater systems. Optimization models are used, aimed at finding optimal configurations for the location, type and size of the system's infrastructure: sewers, pump stations, and wastewater treatment plants. Solutions are evaluated in terms of the cost of installing, operating and maintaining the infrastructure, and the water quality in the river that receives the treated wastewater. The river water quality varies in accordance with the effluent discharges, and is assessed using environmental parameters. The models are solved with a simulated annealing algorithm complemented by a local improvement procedure. Its application is illustrated through a case study in the Una river basin region, in Brazil.
