The town of Pittsburgh discharges 0.126 m3/s of treated wastewater into Cherry Creek. The BOD5 of the wastewater is 34 mg/L. Cherry Creek has a 10-year, 7-day low flow of 0.126 m3/s. Upstream of the wastewater outfall from Pittsburgh, the BOD5 is 1.2 mg/L. The BOD rate constants k are 0.222 d21 and 0.090 d21 for the wastewater and creek respectively. The temperature of both the creek and the municipal wastewater is 208C. Calculate the initial ultimate BOD after mixing.
