Description
This project consists of the replacement of existing plumbing fixtures (Toilets, showerheads and aerators) with water
saving fixtures. The project will replace high-volume toilets (pre-1994) with ultra-low volume (ULV's) or high-efficiency
toilets (HET's) by offering 775 rebates of $100 per year to residential customers of Charlotte County Utilities. ULV's
have a flush rate of 1.6 gallons per flush (gpf) and HET's have a flush rate of 1.28 gpf. Single and multi-family
customers will be able to replace up to two toilets per dwelling. The project will also replace up to 775 showerheads
and aerators with low-flow equivalents. This project will focus on education HET and ULV users on the proper
maintenance necessary to ensure that each toilet remains a water-conserving fixture over a 20-year life expectancy by
focusing on leak detection and proper flapper management.
Benefits
It is estimated that the replaced toilets, once all 775 are rebated, would save approximately 16,839 gallons per day.
The showerheads are expected to save an estimated 4,600 gallons per day and the aerators were anticipated to save
7,031 gallons per day. The total project savings was projected to be 28,470 gallons per day, or 10,391,696 gallons per
year.
Costs
The total project cost is $114,020, with the Peace River Basin Board and Charlotte County Utilities each funding a 50
percent share, or $57,010. The cost amortized at 8 percent over 20 years, was $1.18 per thousand gallons saved
(calculated using a weighted average based on the total benefit for the life of the project).
Additional Information
This is a continuation of the FY2008 Project, which offerred 385 rebates of up to $100 per toilet for multi-family,
commercial and single-family customers. A contractor is administering the program. One year of account-level
metered water-use data prior to and one year of metered water use after the retrofit installation will be collected as the
raw data for the final savings analysis. Charlotte County Utilities will provide actual billing data and ensure 100 percent
fixture inspection through the contractor who is doing the collection. This project will also institute an educational
program designed to assist customers in long-term maintenance related to water savings, such as selecting parts for
repairs, leak detection and choosing proper replacement flapper models for their HET or ULV toilets. ULV Toilets have
a flush rate of 1.6 gpf and HET's have a flush rate of 1.28 gpf. This effort will ensure the retrofit fixture will remain a
water-conserving fixture throughout its life-expectancy. Bi-monthly status reports will be provided to the District to
update project accomplishments.
