Toilet Retrofit
Replace all toilets requiring 2.0 gallons per flush or higher with new water conserving toilets meeting the performance standards for the EPA WaterSense program. Install waterless urinals in situations where watered urinals are used.
RATIONALE
According to the American Water Works Association, toilets consume an average of 20.1 gallons of water per person, per day in a home with no water-conserving fixtures. That’s nearly 30 percent of an average home’s daily per-person indoor water use. Upgrading from a 3.5 gallons per flush(gpf) toilet to a 1.6 gpf model will reduce one person’s annual water use from 27,300 gallons to 12,500 gallons, according to the Federal Energy Management Program. Upgrading to water efficient toilets should be the first fixtures to address when trying to conserve water.
EFFORT REQUIRED
Minimal effort is required. Changes can typically be carried out by maintenance personnel or a licensed plumber.
BENEFITS
Reduction in water use will save money and energy.
RISKS
The risks of implementing water conserving toilets are minimal. Because these low volume toilets use less water, there is a potential for decreased performance. The EPA WaterSense certification confirms water savings and performance for rated fixtures.
ACTION AGENT(S)
Department of Facility Management, building management or homeowners.
COSTS
A typical low volume toilet will cost 5-30% more than a standard toilet. Many communities sponsor rebate programs to encourage adoption and retrofit of low volume toilets.
