39、agement (TWM) was developed in the 1990s because leaders in the water industry sensed that single-purpose water management was outdated and too limited. While utilities competed hard for water and the government developed more regulations, water supplies were still getting scarcer and more degraded.

40、 The origins of the TWM concept stem back to AWWA policies on water resources management and were expressed in a 1994 white paper that was drafted by the Total Water Management Task Force. This task force represented several committees and reported to the Technical and Educational Council and the Wa

41、ter Utility Council. Its chair was Gerald S. Allen, who at that time was with Avatar Utilities in Coral Gables, Florida. At that time, AWWA white papers were written at the direction of the board of directors to address a topic quickly.1When the TWM concept was developed, AWWA was reexamining its ro

42、les on several fronts. A principal idea behind TWM is that the water supply industry should take leadership in resource conservation and in considering water management across the entire hydrologic cycle. While it is difficult to resurrect historical events, evidence shows that debates within AWWA l

43、eadership circles led to TWM becoming a value for AWWA to promote, along with Safe Water for All People and Customer Satisfaction.2These three slogans appeared on the cover of AWWA MainStream in the mid-1990s. The promise of TWM is that we can promote sustainable development by working together to m

44、anage water on the basis of natural systems within watersheds. TWM might seem like a nice idea without much practical use, or it can be a powerful tool to forge cooperation and create win-win solutions among water managers. Its emphasis on stewardship shows that all citizens must participate. Otherw

45、ise, the relentless impacts of land development will degrade water supplies in spite of the efforts of water managers.TWM doesnt lend itself very well to presentation in a manual of practice or a handbook. It is not really a set of steps so much as it is a set of principles. This book organizes its

46、ideas and concepts and can be 1 Thanks to Linda Moody, AWWAs volunteer and technical support coordinator, for this information. She also reported that white papers are rarely written now because hot topics can be addressed in other ways.2 Thanks to Bob Wubbena (president of AWWA, 199596) for insight

47、 into AWWA policy debates of the early 1990s that resulted in new directions and water industry leadership in TWM and related areas. xiiused to create other presentation mechanisms, such as training materials, PowerPoints, and video presentations.TWM offers many examples of ways to be involved. Peop

48、le using its principles might be utility engineers, operators, or administrators. They might also be planners, scientists, or other support staff. They might be running advocacy organizations that reach out to private citizens. They might be leaders in convincing citizens to improve water use and ma

49、nagement by conservation or nonpoint source control. They could be involved in the fishing and recreation industries and be working to keep the waters pure and safe. They might be regulators looking for better ways to regulate. They could be in the water industrys large support sector and want tips about providing products or services. In presenting the book, Im reminded of the strands of history that make up the TWM ideas. I think of AWWA leader Abel Wolman, who
