General The KID is divided into two distinct geographic areas. They are the east service area and the west service area, which is generally divided by the Wilcox Canyon watercourse. The east and west areas are connected by pipelines between the Holly Booster Pump Station, the East Tank and the Vosburg Booster Station. Within each service area are several pressure zones which are serviced by a piping network, reservoirs, booster pump stations, wells and horizontal water tunnels. Water Sources The KID owns and operates two water wells which are the primary source of water for the District. The Wilcox Well supplies the Wilcox Reservoir and the K-3 Well supplies the Eucalyptus Reservoir. Both wells pump from the Raymond Basin from which the District has a 516 acre-feet adjudicated pumping allowance. Both wells are equipped with deep well, oil lubricated, vertical turbine pumps. The KID also owns and operates nine water supply tunnels which were originally constructed by hand in the 1800's to serve the ranches in the area. Tunnel flow rates vary according to the time of year and the annual rainfall and are capable of supplying anywhere from a few gallons per minute up to a hundred gallons per minute or more. Interconnections and Emergency Equipment The KID currently maintains and operates three emergency interconnections with the City of Pasadena which can deliver water to the Vosburg and Eucalyptus Reservoirs. The KID has two trailer-mounted diesel-powered portable booster pumps and one trailer-mounted diesel-powered portable generator for emergency operations at District facilities in the event of a power or pump failure. Reservoirs The KID operates and maintains ten water storage reservoirs at elevations ranging from 940 feet to 1,637 feet with a total capacity of approximately 4 million gallons. Booster Pumping Facilities The KID operates and maintains six booster pumping facilities to move water into the six pressure zones in the system. They are the Eucalyptus, Sage, Holly, Vosburg, Glen and Wilcox facilities. Horsepower of the pumps range from 20 to 75 HP depending on location and purpose. Pipelines There are approximately 70,000 feet of transmission and distribution mains in the KID service area. Piping materials include, galvanized steel, AC, PVC and ductile iron and range in size from 2½" to 12" in diameter. There are approximately 100 fire hydrants providing flows of between 750-2500 gpm with a 20 psi minimum residual. |
