3/21/2025 – Hydrant Flushing Notice – Flushing takes place at night during the hours of 10 p.m.-3 a.m.

The public works staff performs hydrant flushing throughout the year in Milbank.  This procedure clears sediment from the water distribution lines and helps maintain water quality; the hydrants are also checked for maintenance issues.

Residents should refrain from washing laundry when flushing is done in or near their neighborhood, as the temporarily discolored water may cause laundry staining. Instead, on the day of flushing, it is recommended to run the cold water taps until the water runs clear before using the water. This will help clean out any sediment entering the home’s water lines.

Flushing takes place during the hours of 10 p.m. – 3 a.m.

2/11/2025 – Flushing Notice – MULTIPLE AREAS

City personnel are flushing throughout Milbank today.

Water Appearance – rust?

The water appears rust colored.

At only one faucet: This is an indication of possible problems with the internal plumbing, not the water. Please call a plumber to investigate.

At all the faucets: This is an indication the coloration is coming from the water main that provides water to your building.

Flush your household plumbing:

  1. Remove aerators, or the screens, from the end of every faucet and rinse any particles from them.
  2. Start in the basement or lowest level and work your way to the top floor. Fully open each cold water tap and allow the water to run.
  3. Your water should be clear after 10 minutes.  Start at the top floor and turn off the water at each faucet, finishing the basement.
  4. Re-attach aerators to the faucets.

If the water is discolored, continue flushing until clear.  If it is still discolored after 30 minutes, please call the city office at (605) 432-9575.

Rusty water can stain laundry so if you see discoloration avoid washing laundry, particularly white items, until the water clears.  If you see rust stains on your laundry, you may want to try a rust and iron stain remover product found in the laundry detergent section of stores.  We do have some rust and iron remover on hand in the city office.

1/3/2025 – Response to Lead Service Pipe Invetory Letters

The best way to verify the material of your service line is to complete the online survey at survey.sdwaterpipes.com.

The survey will walk you through where to find your service pipe. You should be checking the service pipe within the first 18 inches where it enters the home.  This is generally in a basement, a crawl space, and/or in a utility room.

If you would like to know more about this inventory stage of the lead service line project, you can go to the FAQ’s page on the sdwaterpipes.com website.

What do you own?    You own the entire service line including your curbstop.

No Financing Available    The Department of Agriculture and Natural Resources and the State of South Dakota do not have any financing available.  Currently the City of Milbank does not have any funds allocated for replacing your service line.

Ongoing    If you don’t do the survey this year, we will continue to ask each year – please consider taking the survey so the inventory is accurate and for your own peace of mind.


1/2/2025 – Discolored water

City personnel completed the final water valve adjustments for the 5th Street project earlier this week. During initial testing, the water remained clear for 30 minutes, and the flushing operation was temporarily paused. However, we have since received reports of discolored water in the area. In response, personnel will resume flushing operations this afternoon to address the issue and ensure clear water is restored. Thank you for your patience and understanding as we work to resolve this matter.

The following is taken from our Water page regarding when water appears rust colored:

“The water appears rust colored.
