Help us reduce chlorides at our Wastewater Treatment Plant.  By upgrading  your water softener to a demand-initiated regeneration control  model  you can help make a difference.  Demand-initiated regeneration control means that the water softener will regenerate based on the amount of water that has been treated instead of a timer, reducing the amount of salt you use and send to our Wastewater Treatment Plant.  Wastewater Treatment Plants cannot break down chlorides (residual of the salt) therefore the chlorides are released into our streams and rivers.  By reducing chlorides we will help protect our natural resources.

City of Waterloo ordinance 340-12 (G) requires that new water softeners have demand-initiated regeneration controls with a minimum salt efficiency of 3,350 grains’ hardness per pound of salt.
