Rethink water by replacing older model toilets with Watersense certified toilets to conserve water.  The City of Joliet is  offering a low flow toilet rebate program to qualified water customers.Rebate Program

What is a low flow toilet?

High efficiency toilets are the latest generation of toilets.  WaterSense certified toilets use 1.28 gallons per flush which is 20% less than the current federal standard of 1.6 gallons and significantly less than older model toilets which can use up to 6 gallons per flush.  WaterSense labeled products are backed by independent, third–party certification and meet EPA’s specifications for water efficiency and performance.  These products can be found at local hardware stores as well as home improvement stores like Home Depot, Menards and Lowes.

Why should I replace my toilet?

Replacing 3.5 gallon toilets with WaterSense labeled toilets can save a household 12,000 gallons of water each year.  An average family of four uses 881 gallons of water per week just by flushing the toilet.  Saving water not only saves homeowners money, it decreases demands on the City’s groundwater source which is being depleted.
