... L e e DATE: December 15, 1997 TO: Fred Hoisington, HKGI FROM: Steve Jankowski, City Engineer RE: City of Ramsey Water Supply cc: Linda Waite Smith, Acting City Administrator Jessie Hart, Finance Officer" ". Mark Boos,Parks/Utilities Supervisor Dean Kapler, Fire Chief/Director of Public Works This memorandum is in response to the question as to whether the City of Ramsey can sustain a water demand to accommodate the current rate of growth in its water utility. This question is understandably raised by the fact that Ramsey has purchased water from the City of Anoka since 1995 to meet its peak demand days during the summer months. The development of the City's water utility is guided by a Water Supply and Distribution Plan which was prepared in November 1994. That study predicted the utilities growth rate through year 2004 and recommended $4.87 million in supply and storage (wells and reservoirs) improvements through that period. Specifically, the capital improvement plan called for an interconnection with Anoka's system in 1994, a new Well No.3 in 1996, a new Well No.4 in 1998, and a new elevated tank in 1999. The City has completed the Anoka Interconnect, Well No.3, and is currently drilling Well No.4, anticipating to be on-line by summer of 1998. The City has met the infrastructure goals set forth in its plan. The recommendation of the plan calling for an interconnection with the City of Anoka was made for several reasons. First, it provided an emergency back-up for the City's system in the event of an emergency which might effect either of the two existing wells that are serviced through a single pump house. In addition, Anoka's system had excess well capacity, representing an economic advantage to both the cities of Anoka and Ramsey. It is common design practice for a water utility to provide a combination of water supply and storage such that the utility can meet its peak day demand with its largest single source out of service. This is known as firm well capacity. The table below illustrates the water utilities supply capacity and the system's firm well capacity with each source out of service.
