Storm Sewers and Detention

The storm drains system transports rainwater or stormwater and other runoff from roads, parking lots, and roof downpipes directly to nearby creeks, rivers, or the sea without any treatment.

A river before its entry into a town had a discharge of 200 litres per second and 30 mg/las the
concentration of a conservative parameter. The town's waste water outfall having 250 mg/1 concentration
of the same conservative parameter raised the river concentration to 75 mg/l after complete mixing with
the river water. The dilution ratio resulting from the discharge of the above said waste water at the outfall is

7. (Mass balance, A river with 400 mg/L of salts (a conservative substance) and an upstream flow of 25.0 m³/s receives an agricultural discharge of 5.0 m³/s carrying 2,000 mg/L of salts. The salts quickly become uniformly distributed in the river. A municipality just downstream withdraws water and mixes it with enough pure water (no salt) from another source to deliver water having no more than 500 mg/L salts to its customers. What should be the flowrate mixture ratio F of pure water to river water?
The discharge from the Renenutet sugar beet plant causes the DO at the critical point to fall to 4.0 mg/L. The Meskhenet Stream has a negligible BOD and the initial deficit after the river and wastewater have mixed is zero. What DO will result if the concentration of the waste(L_w) is reduced by 50%? Assume that the flows remain the same and that the saturation value of DO is 10.83 mg/L in both cases.
A company is trying to build a new plant in a location near to a stream.

A waste sludge flow of 40 m³/day is gravity thickened in a circular tank with a diameter of 6.8 m. The solids concentration is increased from 4.5% to 7.5% with 85% suspended- solids capture. Calculate the solids loading in kg/m² d and the quantity of thickened sludge in m³/d.
The base of a river in in contact with the top of an aquifer. A truck carrying bags of powdered cyanide is on a bridge crossing the river when a large bump causes one of the bags to fall into the river. The water in the river suddenly becomes polluted by the cyanide with a concentrations of 6.78 mg/L. The aquifer has an average linear ground water velocity of 0.256 m/day. Laboratory analyses data indicates that longitudinal dispersivity can be found through the equation: a = 0.86(log Ls)² where Ls is the length of the straight line path between two points along the path of transport. Find the longitudinal dispersion 108 m downstream from the bridge. Assume that the cyanide solute has a diffusion coefficient of 3.6 x 10 -5 m²/s and the aquifer has a coefficient related to tortuosity (o) equal to 0.8. Find the coefficient of hydrodynamic dispersion.
A rectangular settling basin has a depth of 3 m, a length of 40 m and a width of 6 m. The water treated in the basin has a flow rate of 500 L/s and contains 50 mg/L of type a particles, 100 mg/L of type b particles and 180 mg/L of type c particles (particle type letters refer to the particles listed in problem 1). What is the suspended solids concentration in the effluent from the settling basin? Determine the overall percent removal of suspended solids from the water achieved by the settling basin.
