'I Chapter 7 " ,", > Contingency Strategy for Water Supply~ The following summarizes the City's alternative water supply plan and contingency strategy that is detailed in the Comprehensive Water Plan - City of Centerville (February 1997). Water system characteristics, water user priority, emergency equipment and contact numbers can be found in the plan. Prior to 1988, the City of Centerville did not have a municipal water system. An initial "Master Plan for the Development of a Municipal Water System" was written in July 1987 to address the development of a municipal water system. In the 1980's and 19908, Centerville experienced rapid increase in population that this plan addresses. Historical Development Trends The City started experiencing dramatic growth during the 19808. This growth trend is expected to continue throughout the next 15 to 20 years. As is commonly the case in rural communities such as Centerville, not everyone within the city limits is connected to and served by the City's water system (due to the use of private wells). In fact, not everyone with a service connection uses the City's water. There are a number of customers who are provided with connections, but who use private wells as their source of water. These customers will be added over time as repair or reconstructions of private water systems are not allowed by the City where Municipal water is available. Planned Development and Population Forecasts The Metropolitan Council's predicted number of households for the year 2020 is 1,750, and the total population projected is 4,650. Projected Service Area Population City of Centerville Year Total Persons per Total % of Pop. Service Area Households Household Peculation Served Population 2000 1000 3.1 3.050 89% 2715 2005 1200 2.9 3.500 93% 3255 2010 1400 2.8 3.950 95% 3.755 2015 1575 2.7 4.300 97% 4.170 2020 1750 2.7 4.650 99% 4.600 Population and household data was interpolated from 1994 Metropolitan Council blueprint forecast data. The percentage of Centerville's population that will be served by City water was determined using the following assumptions: ' · All development in the City what is outside of the current MUSA boundary will be connected to the City's water system. · Service will eventually be extended to some presently developed areas within the current MUSA boundary, including Center Oaks, the Peltier Lake Hills additions, L'A1l1er Estates, and along Centervllle Road between Westview Street and Center Street. Most population growth is expected to occur in the northern, central, and southern portions of Centerville, due to the access provided by proposed collector streets, while commercial and industrial growth is expected to occur in the eastern area of the City.
