Draw a sketch, showing a system (including the raw water reservoir, pump station, water transmission lines, elevated water storage tank, hydraulic grade line, and elevation in meters) based on the following information: the raw water reservoir of Durban is at an elevation of (152.4 m). An automatic booster pumping station is proposed, having for its control point a (2,082 m³) water storage tank. The design tank water level is at an elevation of (149.4 m). Measurement of the water storage tank level is to be transmitted to the pumping station and is to be the only variable used for the control of the pumps in the pumping station. The head losses of the water transmission line between the raw water reservoir and the elevated water storage tank (including the miscellaneous head losses in the proposed pumping station) computed for the rate of flow of (101 L/s) are (12.2 m), which is to be overcome by the pumps. A chlorination system is used for treating the water entering the elevated water storage tank. The chlorinated water from the tank is transmitted to the city's water filtration plant for further treatment prior to domestic consumption.
