Abstract

Management of urban storm-water is characterized by the use of hydraulic structures like culvert, man-made channels, water ways, detention basins, infiltration trench, spillway, dams and other drainage structures to either convey or store the storm-water downstream. But in some cases these structures may not be effective to either convey or store the excess runoff because of some inherent factors like topography, soil type, and other factors could include high rain intensity over a long duration and poor drainage design. In the case of Batu Pahat, some of the contributing factors include; flatness of the catchment area, low infiltration rate of the top layer soil (clayey) and ineffectiveness of the hydraulic structure to perform optimally. By adopting the method of injecting some of the storm-water into the ground (aquifer) through a well (perforated pipe), so as to reduce the peak flow rate reaching these structures and also to increase the potential head of the groundwater. It is expected that this will reduce the amount of surface runoff considerably, reduce the amount of polluted storm-water reaching the surface water bodies and also increase the groundwater potential head which will make water available in good quality and quantity for various uses.
