The vast majority of Minnesota cities use groundwater pumped from wells, which is where Sleepy Eye gets its water. Some cities use surface water such as lakes or rivers as their water supply. The Minnesota Department of Natural Resources manages the use of groundwater.
Below are links to information about some potential contaminants that could affect Minnesota waters, such as lakes, rivers, groundwater or drinking water. The links will provide you with information developed by MDH.
Peak water use days typically occur during the summer when irrigation is prevalent. Sleepy Eye's demand is:
Average Demand: 462,050 gal/day
Peak Demand: 1,080,000 gal/day
WHAT MAKES UP A CITY WATER SYSTEM?
A typical city water system includes:
Wells that supply the water
Sleepy Eye's pumping capacity is 1,000 gallons per minute
Treatment plant that bring the water to desired or mandated levels:
The water is treated in awater treatment plantto remove sediment (by filtration and/or settling) and bacteria (typically with ozone, ultraviolet light and chlorine). The output from the water treatment plant is clear, germ-free water.
Water towers (or reservoirs) that store a reserve of water for peak day needs, fire-fighting and maintaining consistent water pressure.
If the pump is producing more water than the water system needs, theexcessflows automatically into the tank. If the community is demanding more water than the pump can supply, then water flows out of the tank to meet the need.
Sleepy Eye's storage capacity is 750,000 gallons
Water distribution systems - the pipes, valves and hydrants that deliver water to uses
A high-lift pump pressurizes the water and sends it to the water system's primaryfeeder pipes. The water tower is attached to the primary feeders quite simply, as shown in this diagram:
