本powerpoint演示首先简要概述了萨克拉门托郊区水区（SSWD）和北加利福尼亚州水资源的现状。SSWD的供水可持续性 提出的挑战包括: 平衡联合使用成本与费率影响； 预测需求的不确定性； 区域污染羽流；和 地下水的长期下降（透支）。总体规划旨在解决以下问题:它估计了一个可持续发展的目标 SSWD的地下水抽水目标；它开发了一个可持续的 满足SSWD需求的联合使用计划；而且，它估计SSWD可用 地下水抽水能力过剩。水系统总体规划 给出了决策过程。包括数字。

This powerpoint presentation begins by providing a brief overview of the Sacramento Suburban Water District (SSWD) and the current status of the water resources in Northern California. SSWD's water supply sustainability challenges are presented and include the following: balance conjunctive use costs with rate impacts; uncertainty of projected demands; regional contamination plumes; and, long-term decline (overdraft) of groundwater. The Master Plan is presented as addressing the following issues: it estimates a sustainable groundwater pumping target for SSWD; it develops a sustainable conjunctive use plan to meet SSWD's needs; and, it estimates SSWD available excess groundwater pumping capacity. The SSWD Water System Master Plan decision-making process is presented. Includes figures.
