Alternatives Considered The near term demands of the District are such that an increase in the rate of flow from the wells by about 500 gpm (from the 1050 gpm current combined flow rate from the three wells to about 1550 gpm) is necessary. Alternatives considered included purchasing water from surrounding communities and drilling supplemental wells to support the increasing demand. However, because of the age of the pumping units in the three wells (the existing pumping units are 10 years old and normal life expectancy averages about 7 to 8 years for pumping units under similar circumstances), the pumping units will have to be replaced regardless. There are no communities surrounding the District that have excess water supply for more than an emergency situation. Castle Pines Metropolitan District, located immediately south of the District, is also experiencing growth and does not have excess capacity in their well supply system for outside communities, except for emergency, short term supplies, and there is an existing pipeline connecting the two Districts for that limited purpose. The drilling of supplemental wells was considered, however, to increase the flow rate by about 500 gpm from supplemental well sources would require an additional Arapahoe aquifer well, at a cost of about $750,000, or two Denver aquifer wells at a combined cost of about $700,000. Additionally, a short term alternative solution was considered as a cost savings measure in October of 1994. That alternative (as discussed in a letter to John Van Sciwr of CWCB dated October 31, 1994, see copy 14 Jehn Water Consultants, Inc.
