Technology: Faucet Aerators are a mature technology (10+ years in the field) and there appear to be few issues that have not yet surfaced. Measures: Faucet Aerators are not an available measure either through The Regional Technical Forum, or BPA. Faucet aerators are an included measure in the 7th Power Plan. The 7th Power Plan used savings calculations from ETO to develop this measure’s potential. Install: The Faucet Aerator(s) are a direct replacement for the existing aerator supplied with the faucet. Installation is to be done by a Registered Contractor, plumber, or the property manager/owner. A 90% install rate is expected through direct install delivery method. This is based on RTF residential direct install rate. Measure characteristics: Aerators save energy and water by producing forceful streams or a splash-free bubble stream at a reduced flow rate that reduces the volume of water used and minimizes the amount of energy required to heat water. To ensure quality units are installed all aerators will need to be Water Sense Certified. Measure life: 15 years. This is in line with 15 year life used by ETO. Measure savings: We used ETO documentation to develop the kWh savings for the aerator measures. The ETO calculations are used in the development of the 7th Power Plan. Utilizing the ETO calculations, Snohomish PUD calculates the following: - 125.62 kwh/yr. for 1.5 GPM kitchen aerator installation (multifamily) - 143.02 kWh/yr. for 1.0 GPM bath aerator installation (multifamily) - 146.74 kwh/yr. for 1.5 GPM kitchen aerator installation (single family) - 179.48 kWh/yr. for 1.0 GPM bath aerator installation (single family) - 42.42 kwh/yr. for the 1.5 GPM kitchen aerator (retail) - 69.46 kWh/yr. for the 1.0 GPM bath aerator (retail) Cost: $5/Faucet Aerator (bath and kitchen). The unit cost is based on the residential direct install value used in the ETO measure memo and adopted by the 7th Power Plan. $1.70/Kitchen Faucet Aerator and $0.67/Bath Faucet Aerator. The unit cost is based on Snohomish County PUD’s most recent aerator purchase in 2016.
