摘要:

Before the first Distribution System Symposium was held In Los Angeles, Calif. (Feb. 24–27, 1980), there was little or no opportunity for distribution system personnel nationwide to meet and exchange Information. Taking advantage of this historic meeting, AWWA Past‐President Donald K. Shine (1979‐80) and Robert R. Lamson, Director of Technical Services, AWWA, met with five members of AWWA's Distribution Division to discuss the problems distribution systems now face as well as future system needs. Participants Included Ray A. Jackson, Chief of Utilities Operations, Richmond, Va.; Raymond J. Kocol, Engineer In Charge, Milwaukee Water Works Engineering Div., Milwaukee, Wis.; George O. Muller, Assistant Director of Utilities, Water Dept., Arlington, Tex.; John A. Roller, Superintendent, Tacoma Water Div., Tacoma, Wash.; and Harry Snider, Assistant Director, Kansas City Water Dept., Kansas City, Mo.

摘要:

Groundwater recharge with reclaimed water promises a number of benefits: amelioration of problems of overdraft, land subsidence, and saltwater intrusion, thus helping with the resolution of both water quality and quantity problems. It is widely acknowledged that groundwater recharge is a safe, economical, and cost effective method for improving the quality of storing, and transmitting reclaimed water. The July 1980 issue of JOURNAL AWWA explores the subject of water reuse for groundwater recharge.

摘要:

Risk management strategies can enable utility managers to select the best compromise between, on the demand side, the risk and the cost of water use restrictions, and on the supply side, the economic, social, and environmental cost of providing increased capacity.

摘要:

For many water‐short areas where planned recycling of dwindling water resources is or soon will be a necessity, artificial recharge of groundwater aquifers with reclaimed water is among the more promising approaches to reuse. When the end of the cycle is domestic consumption, however, the path is hedged with unresolved questions. What are the important health issues? What water quality standards are appropriate at the points of recharge and extraction? What alternatives are available in water reclamation technology for producing water suitable for recharge? How do these alternatives perform in practice? How does water quality change during percolation and in the groundwater zone? How much do percolation and groundwater passage contribute to overall system reliability? What benefits and problems have been experienced in practice? It was the goal of the symposium summarized here∗ to make progress toward defining and answering these questions.

摘要:

The legislative directive contained in the California Water Code dictates that all possible steps be taken to encourage the development of water reclamation facilities to help meet the state's growing water requirements. Groundwater recharge with reclaimed municipal wastewater is an approach to water reuse that results in the planned augmentation of groundwater supplies.

摘要:

Groundwater recharge with tertiary effluent via spreading basins is practiced in the Dan region project for indirect reuse of municipal wastewater from the Tel Aviv metropolitan area. In addition to effluent treatment, groundwater recharge provides seasonal and multiannual storage, ensures economic as well as psychological merits, and enhances the reliability of the reclamation system.

摘要:

The current application of advanced analytical techniques to the artificial recharge process is shedding new light on the potential of infiltration to remove organic chemical compounds from polluted raw waters and on the possible dangers of contamination in the recharge area.
