Water Use Trends. Discuss factors that influence trends in water demand (i.e. growth, weather,
<br />industry, conservation). If appropriate, include a discussion of other factors that affect daily
<br />water use, such as use by non - resident commuter employees or large water consuming industry.
<br />During the recent 10 year period, the population served by the water system increased by 88
<br />percent and represents approximately 6,650 additional people. The Metropolitan Council forecast
<br />for the City indicates that the City will have approximately 26,250 people and 9,000 households
<br />by the year 2020. All of the additional households and people are expected to be served by the
<br />water system. As current City residents are expected to connect to the water system, it is
<br />estimated that approximately 25,000 people will be served by the year 2020.
