Measure Specific Water Savings Per Option A, Pre measurements with annual post spot measurements will be taken to establish water consumption , for a representative sample of Water Closets , Urinals and Faucets , and pre measurement , with annual post spot measurements for the Water Conservation Measure . These measurements will be accomplished through the use of a calibrated bucket. The results will be used to prorate the calculated savings, thus determining the adjustment (+/-) , to be used in the comparison with the Guaranteed Savings . Equations for Calculating Water Savings To determine estimates of water savings use the following equation : Gallons Savings, _ Ju ( (Gal/Flushbasefine x Quantitybasetine - Gal/Flushp.st x Quantityposd x Number of Occupants]t, ,, where : Gallons Savings = gallon savings realized during the post- installation time period t Gal/Flushbasetine = Gallons baseline per flush for usage group u Gal/Flushpost = Gallons per flush during post-installation period for usage group u Quantitytaseiine = quantity of affected fixtures before the water conservation retrofit for usage group u and the number of flushes Quantitypost = quantity of affected fixtures post water conservation retrofit for usage group u and the number of flushes Number of Occupants = number of people during the time period t for the usage group u , assuming number of people are the same before and after measure installation The Measured First Year Water Savings for all facilities = $ 6 , 185 . This savings will be measured/verified as stated above and converted to savings by applying the flow measurements , water and sewer consumption rates , the usage rates and individual facilities ' occupancy as stated in the Reports . The usage rates and occupancy are hereby stipulated . Indian River County , Florida 15 Indian River County Phase 1 -- Phase I Rev . 1 /05/09
