In planning the agro-industry Waste Water Treatment Plant (WWTP), it is necessary to calculate the waste water which is thrown to the river, because the waste water has anorganic, organic in nature scented orders, brownish to blackish in colour, and contain the oil. In contrary, sludge can turn into a deposit at the river base, which is called as sediment, until it can form a delta. Waste water data is taken from influent of agro-industry WWTP; rubber, oi- palm, and coconut. The sample has been taken by taking in each of sampling point, which was conducted in composite way, in the surface, and 0,5 m in depth. The analysis result of Total Suspended Solid (TSS) content in WWTP outlet of rubber-industry was 125 mg/L and 64,1 mg/L (Biochemical Oxygen Demand, BOD5). The analysis result of oil-palm was 220 mg/L and 89,8 mg/L (BOD5), and from coconut-industry was 83 mg/L.
