Water Conservation Audit- Cocoon House <br /> Washing Machines <br /> The washing machines in both facilities are estimated to use about 41 gallons per load. <br /> It is recommended that 1 washing machine at the Cedar Street site and 2 washing <br /> machines at the Pine site be replaced with new water efficient models that use 24 <br /> gallons per load or less. The estimated cost and savings of this measure are shown <br /> below. Note the savings reflect reductions in water, wastewater and energy (for water <br /> heating). <br /> Estimated measure cost (3 x $600)*: $1,800 <br /> Estimated water usage savings per year (ccf): 62 <br /> Estimated water savings per year: $88 <br /> Estimated wastewater savings per year: $194 <br /> Estimated energy savings (year): $59 <br /> Simple payback period (years): 5.3 <br /> * including installation cost <br /> Before purchasing an energy efficient washing machine you may wish to contact <br /> Snohomish County PUD for their$75 appliance rebate program at <br /> http://www.snopud.com. Puget Sound Energy also has a rebate program for energy <br /> efficient washing machines that save on natural gas heated hot water. <br /> To learn more about water saving washing machine models please visit the following <br /> web site. While the models are listed as to how much energy they use, most machines <br /> that are low energy users are also low water users. <br /> http://www.energystar.gov/index.cfm?fuseaction=clotheswash.search clotheswashers <br /> Toilet Leaks <br /> It is recommended all toilets be tested for leaks every 6 months. A simple way to test for <br /> leaks is to place a dye tablet or a small amount of dye in the tank of the toilet. Do not <br /> use the toilet and return in 20 minutes. If there is dye in the bowl of the toilet, it means <br /> the toilet has a leak. You should then examine the toilet to determine if it is functioning <br /> correctly. <br /> Many toilet leaks occur because the toilet flappers are no longer sealing properly. If this <br /> is the case, you can easily replace the flapper(s). Be sure to obtain flappers that are <br /> designed to work in the toilets that you have. Your maintenance staff should also <br /> periodically inspect and replace the valves in the tank toilets every six months. Also, <br /> please keep in mind that many toilet tank chemical cleaners, have been found to make <br /> toilet flappers dissolve. Therefore it is important to only use non-toxic toilet tank <br /> cleaners. <br /> The Toiletology web site has a lot of useful information on how to maintain tank style <br /> toilets: http://www.toiletology.com/index.shtml. <br /> 65 <br /> 10/11/2004 Page 5 <br />
