CHAPTER 6 - CONSERVATION GOALS Water Conservation Goals In review of the water demands and costs shown above, the City of Fort Lupton recognizes the need to further develop its water conservation goals. The three largest users within the City are Residential, Thermo and City Irrigation. Goals were established for these three users through discussions with City staff and cooperation with customers within these categories. Residential The City's residential per-capita water usage is 173 gpcd. One goal is to reduce this per-capita water usage to 161 gpcd. This water savings can be measured by dividing the total water usage by the current population as the City moves into the future. However, a key component of this is to get a good handle on the billing records. The discrepancy from what is measured leaving the WTP versus what is measured at the individual service meters is currently too high. It is important that the City work to improve the unaccounted-for water because it is difficult to track water use and may be a source of unrealized revenue. Once these discrepancies are resolved, this water savings can be measured. The City targets a 1 O-year reduction of 50/0 and a long-term reduction of 70/0. If Table 4.2 is revised accordingly, the 2016 water demand is reduce from 1 ,873 ac-ft to 1,742 ac-ft or 131 ac-ft. The 2030 projected water demand is reduced from 2,833 ac-ft to 2,639 ac-ft. This is a long-term target water savings of 194 ac-ft or 70/0. Thermo Thermo is a very large Commercial/Industrial user in the City. Current water use at the power plant is measured only by Thermo at the end of the pipeline from the 1-MG well water tank at the tank farm. Since Thermo's water usage is 390/0 of the City's total water usage (potable + non-potable) and 860/0 of the City's well water usage, conservation at the power plant would be beneficial. The City met with Thermo to ascertain possible water conservation measures at the power plant. Thermo significantly reduced its water usage in 2002 by improving operations at the plant. The primary change, which involved renegotiation of Thermo's contract with Excel Energy, was to correlate electricity production with demands. Thermo reduced its water use from an average of 938,000 gallons per day to 586,000 gallons per day, or 380/0. As suggested earlier in this report, the City would also like to evaluate if the backwash water from the WTP could also be included in Thermo's raw water acquisition program.
