<br />c. SERVICE UNITS FOR WATER AND WASTEWATER <br /> <br />Chapter 395 of the Local Government Code requires that impact fees be based <br />upon a defined service unit. A "service unit" means a standardized measure of <br />consumption or discharge attributable to an individual unit of development. With this <br />impact fee analysis, the City will adopt a 5/8" x 3/4" displacement type water meter as a <br />service unit for both water and wastewater. This is the size and type of meter typically <br />used for a single-family dwelling and therefor is considered to be equivalent to one living <br />or service unit. <br /> <br />.Other meter sizes can be compared to the 5/8" x 3/4" meter throu.gh a ratio of <br />water flows as published bY'the American Water Works Association as shown in Table 1. <br />The ratio of the maximum continuous duty rate between the service unit size of 5/8" x <br />3/4" reflects the service unit equivalents (SUE's) or equivalent single family dwelling <br />units that are being placed on the system. A development's meter size is calculated based <br />upon the pressure at the meter outlet, type of customer to be served and number and type <br />of plumbing fixtures. <br /> <br />Table No.1 <br />Livin<g Unit Equivalencies For <br />Various Types and Sizes of Water Meters <br /> <br /> <br />Displacement 5/8" x 3/4" 10 1.0 <br />Displacement 1" 25 2.5 <br />Displacement 1-1/2" 50 5.0 <br />Displacement 2ft 80 8.0 <br />Compound 2" 80 8.0 <br />Turbine 2" ]00 ] 0.0 <br />Compound 3" 160 16.0 <br />Turbine 3" 240 24.0 <br />Compound 4" 250 25.0 <br />Turbine 4" 420 42.0 <br />Compound 6" 500 50.0 <br />Turbine 6" 920 92.0 <br />Compound 8" 800 80.0 <br />Turbine 8" ] ,600 160.0 <br />Turbine ] 0" 2,500 250.0 <br />Turbine 12" 3,300 330.0 <br />(a) Source: A WW A Standard C700 (1995) - C704 (] 996) <br />
