Mission & Responsibilities


The City Le Sueur Water Utility Department's mission is to provide clean, safe, water to all of the residential, industrial and commercial sites in Le Sueur.  Our process is to pump water from our wells, treat it to remove the iron and manganese, add chlorine and fluoride, pump it to our 3 water towers for storage, and make it available to our residents, industries, and commercial customers via the City's water main system.

We continually test and monitor the water for quality. Prior to treatment (raw), irons .73 mg/liter and manganese is .135 mg/liter. After water is treated (finished), iron is .06 mg/liter and manganese is .032 mg/liter.

When to Call for Emergency


Call the Water Utility Department if there is no water, or low pressure in your building or water is coming up out of the ground

If water is spraying in your house/building, call a plumber. The City owns the water mains - home and building owners are responsible for the lines from these mains into their homes and buildings

Rusty Color in Water


Minnesota well water naturally contains a lot of dissolved iron.  LeSueur’s filter treatment process removes 96% of the naturally occurring iron within the water.  However there is just enough iron remaining after treatment, that some of the remaining iron can precipitate out of the water when it is exposed to chlorine for a long period of time.

During the spring, summer and autumn months, our customers use enough water for irrigation and other purposes to keep the water flowing quickly through the water mains. The water never has an opportunity to age. During the winter months, however, water use is much lower, allowing the water to flow very slowly through the water mains. This longer exposure time contributes to the precipitation of iron in the water mains. It is a very small amount of iron, but enough to settle out in the bottom of some of the water mains.

The City of LeSueur flushes the entire City water distribution system every spring to remove this sediment and to make sure the fire hydrants operate correctly. During the flushing period, there are a few places in town where this “rusty” water can accumulate, and if you happen to turn on your faucet in that particular neighborhood where the crews are flushing, it is possible that you might draw some of this reddish water into your home before it has a chance to be flushed out into the street. If this happens, turn on your cold water faucets throughout your house, and let the water run for about five minutes to clear the lines.
