Water Rebates and Discounts

Starting on January 1, 2020, the following rebates will be available for City of Longmont residents and businesses through Efficiency Works.

High-Efficiency Toilet Rebate


The City of Longmont's high-efficiency toilet rebate will now be offered through Efficiency Works. Review the new requirements below and select this link to apply for a $50 high-efficiency toilet rebate.


  • Replace your old 3.5 gallon per flush (GPF) toilet(s) or greater with a new qualified, high-efficiency toilet (WaterSense certified 1.1 GPF toilet with a  MaP score of 600g or higher). Residential customers are limited to two toilets per year and must submit their rebate application within the calendar year of the new toilet's purchase.
  • How do I know the GPF of my existing toilet?
    • To find the GPF on your existing toilet, look under the toilet lid or on the back of the toilet bowl behind the seat. If the GPF is not listed, the appliance year should be inside the toilet tank or under the lid. Please note that homes built after 1994 will not qualify for the current toilet rebate program since laws were passed requiring the installation of lower flow toilets during that year. 
    • Find the year your home was built at the Boulder County Assessor webpage.
  • How do I check if a dual flush toilet qualifies?
    •  A dual flush toilet qualifies if the average of one full flush and two reduced flushes is 1.1 GPF or lower. For example, a dual flush toilet that is 0.8/1.28 GPF has an average of 0.96 GPF and would qualify.

  • What is a MaP score?

How to participate

Recycle your toilet

  • Recycle your old toilet at the City of Longmont Waste Diversion Center at 140 Martin Street    
  • Old 3.5 gallon toilet/urinal drop-off hours: Monday - Saturday, 7:30 am - 4:45 pm. Closed Sundays and holidays.
  • Requirements for recycling:
    • You must bring an e-mail or copy of your receipt from Efficiency Works stating that you have participated in the program.
    • Important: only the porcelain is accepted. All metal and plastic must be removed, this includes tank levers, flush valves, fill valves, gaskets, bolts, and toilet seats. If any metal and plastic parts remain on the toilet, the toilet will not be accepted.
    • Why is only the porcelain accepted? The City of Longmont Street Department will be adding the toilets to their asphalt pile, crushing them, and using them for road stabilization and other backfill projects. If there is any metal or plastic on the toilet, we will be unable to add it to the asphalt pile.
