4. Comparative Billing System The City's water billing system maintains a data base for each customer. Upon request, a customer can obtain previous water use by their account for comparison to current` uses, which enables customers to compare water use over time (e.g. from year to year or season to season). Customers can then effectively monitor their water use and conservation efforts. 5. Water Distribution System The City's water distribution system has been divided into four pressure zones in order to limit water pressures to the levels recommended by current building codes. In areas where main line pressures exceed the target levels specified in the building code, the City requires that a pressure regulator be installed between the water meter and the customer's first water outlet. Regulators are set to Limit pressures to no more than 70 psi. Installation of the regulator is the responsibility of the ;builder and maintenance is the responsibility of the owner. The Utilities Plans Examiner determines when regulators are required during the pian and permit review process. Pressure management conserves water in several ways. First, pipelines under lower pressure tend to leak less than similar pipelines under higher pressures. Second, water use by customers is reduced particularly where large landscapes are involved) due to the reduction of misting and evaporation at sprinklers. Third, pipelines under lower pressures are less subject to large water losses following ruptures. It should be noted 'that pressure management has not been shown to produce measurable savings where the customer already throttles back fixtures such as showers or sinks, or where fixed volumes of water are used as in baths, dishwashers, or clothes washers. 6. Telemetry System The City has completed a network of computer controlled telemetry stations at each of its reservoirs and well pumping plants. The telemetry system allows Utility Department's management to closely monitor water production and reservoir levels, effectively eliminating reservoir overflows that occurred in the past. 3
