3. A 55.0 ML/d wastewater treatment plant
discharges to a river system with a
maximum spring flow of 149.5 m3/min and
a minimum summer flow of 98.2 m3/min
(upstream of the outfall from the plant).
What total allowable BOD (mg/L) could be
discharged by the plant if the BOD in the
river after dilution must not exceed
provincial standards, and there is already 1.1
mg/L of pollution in the river upstream?

Q- A river has a flow of 1000 million litres per day (MLD). BOD5 of 5 mg/litre and Dissolved Oxygen (DO) level of 8 mg/litre before receiving the wastewater discharge at a location. For the existing environmental conditions, the saturation DO level is 10 mg/litre in the river. Wastewater discharge of 100 MLD with the BOD5 of 200 mg/litre and DO level of 2mg/litre falls at that location. Assuming complete mixing of wastewater and river water, the immediate DO deficit (in mg/litre, round off to two decimal places), is

The town of Viracocha discharges 17,360 m³/day of treated wastewater into the Pachacamac Creek. The treated wastewater has a BOD5 of 12 mg/L and a BOD decay constant, k, of 0.12/day at 10 °C. Pachacamac Creek has a flow rate of 0.43 m³/s and an ultimate BOD, Lo, of 5 mg/L. The DO of the river is 6.5 mg/L and the DO of the wastewater is 1.0 mg/L. Compute the DO and the initial ultimate BOD, Lo, after mixing. Draw the Mass Balance Diagram.
Question
You are responsible for calculating the peak discharge for a culvert design in a smallwatershed in Washington, DC. The watershed area is 4 acres and currently has 30 % of its area ofindustrial (heavy areas) and 70 % of residential (single –family areas). The design manual suggestsyou design your culvert for a 10 return period. The watershed has a concentration time of2 hours. Calculate:a) What is the design peak flow?b) What is the impact of the runoff coefficient (C) range on your design?c) After you implemented your project, the residential area was entirely converted toindustrial areas. Would that affect you design? If yes, by how much?
