Optimal wastewater plant capacity expansion is reexamined for the general case where effluent receiving water standards vary with time. A deterministic dynamic programing framework is used to find cost‐minimizing expansion plans for wastewater treatment when hydraulic demand is assumed known and nondecreasing with time. The effect of discount rate, initial hydraulic capacity, and initial plant pollutant removal rate on expansion plan is investigated. Results show time‐variable effluent receiving standards can significantly influence cost‐minimizing expansion plans.
