XIII. Pumping Station The University owns and operates its own water supply system* The water is pumped from six deep wells, which are located among the group of engineering buildings. The water is raised from a body of sand, the mean depth of which is about 140 feet below the ground surface. 1. 2. 3. Large air tanks for equalizing the pressure in the water mains. Two underwriter pumps to be used in case of fire to incresae the water pressure—capable of supplying six large fire streams. Two motor-driven centrifugal pumps used for pumping the ordinary University water supply. These pumps run day and night and may also be used in case of fire. XIV. Hydraulic Laboratory (Of the Departments of Municipal and Sanitary Engineering and Theoretical and Applied Mechanics.) Equipped to give instruction in and to investigate problems connected with water supply engineering, water power engineering, the pumping and distributing of water for manufacturing plants, such as paper mills, chemical and other industrial works, for fire protection, drainage, etc., sewerage and sanitary engineering. 1. Three-stage centrifugal pump driven by a variable speed induction motor in operation. This pump is capable of raising 175 gallons or water per minute a height of 460 feet. Leffel reaction turbine in operation. A type of turbine used for low heads. Duplex direct-acting steam pumps in operation. Used for pumping water into a 60-foot stand pipe. Demonstration on a water meter testing apparatus. A type used in city water departments for calibrating meters. Demonstration with a fire stream under high pressure. Demonstration on a motor-driven centrifugal pump. Demonstration on a Doble Tangential Water Wheel. Wheels of this type are used in hydro-electric power plants which operate at a high head (500 ft. or more). Demonstration of various methods of measuring water: Weir, vertical orifice, vertical jet, etc. A miniature water filtration plant, in operation. A miniature sewage treatment plant, in operation. 2. 3. 4. 5. 6. 7. 8. 9. 10.
