.~ Section 6 WATER PRODUCTION & DISTRIBUTION Water Treatment Plant , 1 Loveland operates one water treatment facility, Chasteen's Grove Water Treatment Plant, located nine miles west of the city. The first treatment facility was a slow sand filter installed at the present plant site in 1906. As growth continued, the City expanded and updated the plant. The last expansion was in 1981 when the plant's capacity was expanded to 30 million gallons per day (mgd) and designed for an additional expansion to 46 mgd. Loveland's raw water supplies are of extremely high quality, except when the turbidity in- creases in the Big Thompson River during the spring runoff. A water treatment optimization study was completed in 1995 and identified capital projects to improve and optimize all com- ponents and processes at the plant. Water Production Water production records show the amount of water leaving the water treatment plant and entering the distribution system. The treatment plant records daily water production by using a weir, an aperture that measures the rate of flow. The unit of measure for water pro- duction is millions of gallons. In 1995, the City discovered the weir was not calibrated correctly and hired an engineer- ing firm to recalibrate it. The firm determined that flows three million gallons a day and be- low were correct, but as flow became greater, the error increased based on a logarithmic scale. High flows measured as much as 15 percent high. For instance, a flow of26 million gallons a day measured on the weir would actually be 22.5 million gallons a day. The production numbers used in this report were recorded from the weir. Only the peak day numbers have been adjusted from the original measurements to reflect actual production. Table 16 is a record of monthly plant production from 1990 to 1995. I I j May 1996 26 Water Conservation Plan
