Pre-softened water may one day flow through Woodbury's pipes-ending the need for water softeners in thousands of households.

At the city council seminar on October 20, officials raised the possibility of establishing a city-wide softened water system. "We will review and discuss the pros and cons," said Jim Westman, Assistant Director of Public Works.

The advantages of this system include saving water, limiting the amount of salt that flows into rivers, and removing minerals that damage pipes under homes and city streets.

Disadvantage? A city-wide system will cost approximately US$100 million. Westerman said that such a system requires additional sources of funding.

Woodbury is revamping most of its water supply system. The city recently received part of a $850 million settlement, which was paid by 3M in 2018 to end an environmental damage lawsuit. 3M produces perfluorinated chemicals used in domestic products, and traces of these chemicals have been found in drinking water in some cities in Washington County.

In Woodbury, the money will be used to purchase an additional city well, a new water filtration station, and filters for 15 of the city’s existing 19 wells.

3M's funds will not directly cover the cost of the water softening system, but savings can be achieved by carrying out multiple projects at the same time.

Water softening is a process used to remove minerals from water. Most water softeners require the addition of salt, which combines with minerals and is then flushed into the city's sewer system.

Westerman of Woodbury says that some household water softeners regenerate twice a week, using up to 30 gallons each time. He said that annual water savings could reach tens of millions of gallons. Woodbury building helps calm moody Woodbury man charged with possession of child pornography
