approximately 55 feet of vertical elevation, with manual interconnections to several neighboring communities. The existing water system and its major facilities are depicted in Figure No. 8 -1, Existing Water System. WATER SUPPLY Water is pumped from five wells. These wells are all located within the southern section of the City and all obtain their water supply from the Jordan Aquifer. The Jordan Aquifer is the predominant aquifer in the majority of the Minneapolis /St. Paul Metro Area. In Lino Lakes the Jordan Aquifer only exists beneath the southern section of the City. There is no suitable aquifer for a well in the northern part of the City. Well No. 1 is located along Black Duck Drive, east of Reshanau Lake. This well was constructed in 1971, is approximately 306 feet deep, and was renovated in 2002 with a motor upgrade, VFD installation, and an increase in capacity of 350 gallons per minute (gpm) to total 675 gpm. Well No. 2 is located along Sand Hill Drive, south and west of Rice Lake. This well was constructed in 1986, is approximately 258 feet deep, and was also renovated in 2002 with a VFD installation, and an increase in capacity of 250 gallons per minute (gpm) to a total of 625 gpm. Well No. 3 is located south of Well No. 1 along Birch Street. It was constructed in 1995, is approximately 281 feet deep, and is the largest capacity well in the City, capable of pumping in excess of 2,000 gpm gallons per minute. It currently pumps at 1,200 gpm and has a capacity of 1,800 gpm Well No. 4 is located near the intersection of Clearwater Creek Drive and Cedar Street North. This well was constructed in 1996, and is approximately 338 feet deep. The capacity is 750 gpm. Well No. 5 is located along Black Duck Drive. It was constructed in 2005 and is approximately 273' feet deep with a capacity in excess of 1,600 gallons per minute (gpm) but normally pumps in the range of 1000 gpm to 1,100 gpm. Table 8 -1 presents pertinent information regarding the five wells which have been constructed by the City of Lino Lakes.

City records were reviewed over the past several years to establish design parameters for this Plan. 8 -4 • • •
