The study will examine the ability of recycled aggregates and sand to classify wastewater in a manner that decreases the level of environmental pollution. The sample was taken from Kg Wang Ulu, Perlis agricultural district, Jejawi, Perlis industrial area and Taman Desa Katong, Perlis residential area. Water quality research has been investigated to find the characteristics of effluent such as suspended solids, BOD, COD and TSS. Three rainfall intensity values, of 5 LPM as low rainfall, 12.5 LPM as mean precipitation intensity, and 22.5 LPM as high-cut rainfall consisted of recycled aggregate and high-absorptive sand as drainage beds, were included in this operating system. Experimental findings indicate that the recycling of aggregates and sand filters has a positive effect on water in industrial and residential areas. It shows that the use of recycled aggregates as a drainage bed can increase the permeability of the region by reducing erosion, preventing flooding and promoting natural infiltration.
