County Of Marshall issued the following announcement on Nov. 04.
Marshall residents are saving an average of 74 pounds of salt per month by optimizing and replacing their water softeners. To see these savings yourself, sign up for a free water softener optimization and find out if you are eligible for rebates up to $700 for residents to replace softeners 15 years or older, and inefficient softeners. Marshall businesses are eligible for rebates up to $4,000. To sign up, contact a contractor on the approved list at ci.marshall.mn.us/rebate or call 537-6776.
