INTEGRATED PLANNING FOR WATER SUPPLY SUSTAINABILITY - THE ALBUQUERQUE BERNAILILLO COUNTY WATER UTILITY AUTHORITY EXPERIENCE

摘要

In the mid-1990s the Albuquerque Bernalillo County Water Utility Authority (Authority) embarked on developing and implementing a Water Resources Management Strategy (Strategy). The Strategy considered multiple water supply alternatives in a triple bottom line framework through a structured multi-attribute decision process. This process allowed for a development of a logical defensible strategy that could meet the long-term needs of water users. This process also resulted in a structured process to evaluate more than 32 supply alternatives, realized in a suite of supply projects creating a diverse water supply portfolio. Chosen projects included, wastewater reuse, surface water supply, groundwater production, and ASR. The Strategy has been continuously updated and refined as new information becomes available or as lessons learned are realized. The Authority is in the process of evaluating additional reuse demand as well as water availability of municipal wastewater for future reuse and ASR projects and is assessing the potential effects of climate change on available supply. In addition, the Authority is developing a dynamic simulation screening tool that will allow for rapid analysis of multiple alternatives for future long-term sustainable supply.
