Salt Use Reductions and Chlorides

Salt use, both from water softeners and from de-icing in the winter leads to long term damage to both fresh water and drinking water.  Monona residents and businesses can help prevent chlorides from reaching our water resources by educating themselves and the contractors they hire to perform de-icing tasks as well as water softener adjustments or replacements.  Please visit WI Salt Wise for more information.

Curb Stops

The curb stop/box is the property of the water utility and may only be turned on/off by an authorized employee of the water utility. Plumbers may turn the water on to test their work but must leave the water turned off upon completion of the work. Please call 222-2525 to request that a curb stop/box be turned on/off. A construction meter is required for all water use.

A 48-hour notice is required to schedule an appointment to have a curb stop/box turned on/off.
