Table 7. Estimated water use for general population with retrofit devices installed (in gallons) Per capita General General Per household per day Per household Population population Estimate (based on 2.6 per day per year per year per day persons per (13,000 taps) (13,000 taps) household) Indoor water 161.0 61.9 58,765 763,945,000 2,093,000 usage Decreased 34.1 13.1 12,447 161,804,500 443,300 indoor water use Potential impact on rates If 13,000 Loveland households installed retrofit devices, residential water use could possibly decrease by as much as 162 million gallons (496 acre-feet) per year. This would be enough water to serve approximately 496 four-person households, based on the assumption that a family of four uses about an acre-foot of water a year. If new residents were not available to use this water, approximately $354,000 would be lost in revenue using the 1994 water rate of $2.19 per 1,000 gallons for residential customers living inside the city limits. Water rates would need to be increased to meet debt payments and operating costs, although costs for treating water would be reduced by approximately $9,700 per year, based on treatment costs of$60 per mil- lion gallons. Also, if the Water and Power Department furnished the retrofit devices, water rates would have to increase an additional amount to pay for the materials. Project Costs Table 8 outlines the expenditures for the entire project. The total cost for 591 indoor water use assessments and retrofits was $26,179.54. The cost per home was $44.30. The City purchased more fixtures than were installed during the project. This surplus is stored in the City warehouse and will be distributed to customers free of charge during other promotions such as Earth Day or National Drinking Water Week. The City has paid for these additional devices. 12
