Water meters were installed on all service <br />connections in the city. The water Spanish Fork uses for irrigation initially comes from <br />groundwater wells, which is then pumped into a large reservoir before pressurizing and <br />distributing to the city. To ensure high quality of the water and to reduce the chance of fouling <br />meters, the city filters the water to very fine particle size. City engineers have noticed a dramatic <br />decrease in water consumption since the installation of the meters. Before meter installation, the <br />water elevation in the large regulating reservoir would drop 2-3 feet per day. After the meters <br />were installed, it was noted that the water level dropped only 6 inches per day. Residents of <br />Spanish Fork were surprised they were using so much water when they saw the amount shown <br />on the new monthly water meter bills. <br /> <br />Experiences like these suggest that water metering causes a significant reduction in water use. <br />The full potential of residential irrigation water conservation from metering has yet to be <br />completely realized. Metering of secondary water seems to be a potential area of much interest <br />in the future as population growth continues and drinking water supplies become strained. <br /> <br />This proposal aims to outline a research project to find an economical meter that can be used for <br />residential secondary water use, specifically for water that is not treated and contains <br />impurities. The main goals of this research project are 1. To define the requirements of <br />secondary water meters for small diameter pipes, 2. To test the performance of available meters <br />to these requirements, 3. To determine if ,m existing product is acceptable and economical. If the <br />price goal cannot be met, then a new product could be designed using the information gained <br />during this project. Development of a new product is not within the scope of this project. <br /> <br />This project will be conducted in Utah but information gained during this research project will <br />benefit irrigation water suppliers in any state that currently provide secondary residential water <br />or plan to in the future. Water metering and conservation is important to all water suppliers in <br />the Western United States, particularly Utah, Idaho, and Colorado because of their interest and <br />investment in secondary water. <br /> <br />The following tasks will be accomplished in this project: <br /> <br />1. Literature review <br /> <br />2. Market analysis <br /> <br />3. Metering survey <br /> <br />4. Water quality investigation <br /> <br />5. Meter testing <br /> <br />6. Development of Meter specifications <br /> <br />3 <br /> <br />f <br />
