摘要:
In July 1979, the city council of Loveland, Colorado passed an ordinance requiring all new residential construction and ownership transfers to install water meters. The following June, a subsequent ordinance requiring all water services to be metered was passed. The bidding process was facilitated by dividing the city into six geographic areas. After installation began in February 1981, a variety of problems was encountered, including meter delivery delays, defective materials, existing underground sprinkler systems, failure of old galvanized or lead service lines, check valve difficulties, and problems with conversion to metered water rates, adequate staffing, and revenue estimates following that retrofit program. Effects of water meter installation are summarized.

摘要:
In water systems, the greatest amount of energy is consumed by pumping. Other usage components are lighting, heating, ventilation, and air conditioning (HVAC), and water treatment. Proportions of consumption will vary among systems supplied by surface water or groundwater. This article provides guidelines for optimum pump selection, advantages of variable speed pumping, and a performance comparison of two variable‐speed raw‐water pumps. Part two of this article discusses optimum use of storage facilities and use of available rate structures (type DIALOG AN 0011123).
