3. Water Trunk and Subtrunk Distribution Mains <br /> • <br /> A network of pipes and related appurtenances usually in the size range of ten <br /> inch (10") to sixteen inch (16"). These pipes are designed to carry large <br /> volumes of water and interconnect various point sources of water supply and <br /> storage reservoirs. Appurtenances to these facilities would include valves and <br /> fittings,but not fire hydrants. <br /> 4. Water Main Laterals <br /> A network of water pipes and related appurtenances usually six inches (6") or <br /> eight inches (8") in size that are installed with approximately eight feet (8') of <br /> ground cover to retard freezing and are designed to serve those buildings <br /> abutting a given street or easement. Lateral mains are "looped" wherever <br /> possible to balance pressures and to provide water from at least two (2) <br /> directions so that continuous water service is maintained for most people <br /> during a water main break. Looping of lateral mains eliminates dead end <br /> water mains that cause a variety of distribution and stagnation problems. <br /> Appurtenances to these facilities would include valves, fittings and fire <br /> hydrants. <br /> 5. Water Main Building Service <br /> • These pipes lead from laterals (or sometimes from trunk and subtrunk mains) <br /> and serve individual buildings abutting thereon. The size of the service <br /> usually ranges from three-quarter inch (3/4") to six-inch (6"), depending upon <br /> the type of building served. The lines terminate at the property line with a <br /> shut off valve and are plugged until such time that the building is connected to <br /> the water system. <br /> The property owner must make arrangements with a licensed, bonded plumber <br /> to complete the service connection. <br /> 6. Water Connection Charge <br /> This is a charge billed to all properties at the time of connection to the water <br /> system. The charge is the individual property share of the cost of the trunk, <br /> source, and storage facilities that make water service available. The charge is <br /> based on the size of the connection, plus the material and installation cost of a <br /> water meter. The current charges are outlined in the City Fee Schedule. <br /> Neither of these charges may be assessed against the property. <br /> 0 <br /> 2004 Assessment Policy—Page 17 <br />
