Water Supply Reserve Account - Grant Application Form Fonn Revised May 2007 additional wells located in the southwest quarter of the northwest quarter of Section 11; this being southeast of the city. These three wells, apparently no longer used, still retain their water rights under the decree. The actual locations of several of the city wells do not coincide with the locations listed in the State Engineer's database. This indicates that they have been replaced and/or relocated since the 1973 decree. Very little information on the existing wells is available from the city. Individual well installation, equipping and test pumping reports are not available. Thus, it is not known when each well was actually constructed. If a well is original and has not been re-drilled, the likely installation date is around the date of appropriation as listed in the State Engineer's database. Each well is equipped with a submersible well pump. Hydraulic calculations estimate that the horsepower of the well pumps range from 15 to 30 hp, depending on the rated pumping capacity. This range of horsepower of the pump motors would typically require a 240-volt or 480- volt, 3-phase service. Wells currently designated as Nos. 2 through 7 consist of a bored hole to a depth ranging from 26 to 36 feet deep. The hole is cased and has a well screen in the bottom. Static water levels are approximately 8 to 10 feet below the ground surface. These wells have a well cap on the top and are enclosed within an individual well house. The well houses consist of small masonry block buildings, each with a removable wood roof for access to the well pump. Well NO.1 consists of a 24-foot diameter hand-dug, concrete lined cistern installed around 1919. Discharge is through an in-ground meter vault. All of these wells are controlled by a supervisory control and data acquisition (SCADA) system to start and stop the wells based on a call from the WTP. According to the city staff, Wells 1,6 and 7 are the best, most reliable producers. Historically, each well was metered with monthly pumpage being reported to the State Engineer's office. However, in 2003 the state allowed the city to report the combined well pumpage using the WTP flow meters. Thus the existing meters at each well have not been calibrated in three years. The following table is a summary of the information available on each of the city's 11 wells as adjudicated in the May 7,1973 Water Court Decree for Case No. W1577.
