A technique for selecting the optimal expansion schedule for sewage treatment plants with constrained effluent loads is described. The treatment plant is described mathematically as a simple network and linear constraints are developed for pollutant loads in the effluent. Dynamic programming is shown to be an efficient method of programming capacity expansion schedules under these constraints. A case study near Melbourne, Australia is described and results are presented for a range of effluent constraints.
