##### Reference no: EM13546934

Calculate the surface area required for a stabilization pond to serve a domestic population of 1000. Assume 80 gpcd at 210 mg/l of BOD. Use a design loading of 20 lb of BOD/acre/day. If the average liquid depth is 4 ft, calculate the retention time of the wastewater based on influent flow. The effluent is spread on grassland by spray irrigation at a rate of 2.0 in/week (54,300 gal/acre/wk). Compute the land area required for land disposal. In these computations, assume no evaporation or seepage losses from the ponds.
