New Frontiers for Water Management: The California Experience
- Resumen
- In rapidly growing regions in the United States, water managers face difficult challenges in mobilizing new water supplies to meet new demands. Environmental concerns have curtailed the scope for large new surface storage projects, and basin overdraft limits groundwater¿s potential as a source of expansion. Drawing on the California experience, this article explores modern water planning approaches, which focus on a portfolio of options including nontraditional sources (recycling, underground storage) and more efficient use of existing supplies (conservation and water marketing). It reviews the advantages and drawbacks of the elements of the portfolio and provides examples of innovative planning approaches. <br/> California has made considerable progress in expanding non-traditional sources, particularly since the early 1990s, when a prolonged drought and a series of environmental rulings constrained traditional supply sources. Many of the current challenges are institutional, rather than technical. For water marketing, continued progress is needed to resolve concerns of third parties in the source regions. For underground storage, further development of aquifer management protocols is a precondition. Progress in urban conservation will require more aggressive use of tiered water rates and shifts in public perceptions regarding landscaping. Changing public perceptions is also key to the successful expansion of recycled wastewater.
