认为区域, 当地的行动
Metropolitan was born out of the need to import water from hundreds of miles away to support a growing region. 但随着南加州的发展,大都会也在发展. 今天,我们远不只是水进口国. 我们是建设者和规划者, making large-scale investments in local supplies to complement our imported supplies. 我们对自然保育的支持, water-use efficiencies and diverse local resource programs like water recycling, 海水淡化, 地下水的回收和储存为该地区提供了近7800万英亩英尺的资源组合, 大大提高了我们的弹性和可靠性. 而我们才刚刚开始. 大都会正在开发可能是世界上最大的水循环设施 纯水南加州.
It’s not an either-or situation -- we’re developing local resources and shoring up our imported supplies. 我们的供应组合的每一部分都是相互依赖的. 一个保证我们不受另一个的伤害. 当进口受到干旱周期或自然灾害的挑战时, local resources and conservation programs can help meet regional demands. 反过来, high-quality imported supplies are necessary for recycling and groundwater replenishment programs. Working together, these sources provide Southern California with reliable water. Having access to a mix of water resources has protected the region from the impacts of drought cycles, 气候变化和极端天气.
本地物料供应 区域的可靠性
当一个地方的供应被开发出来,无论是在文图拉, 圣地亚哥, 或任何介于两者之间的社区——所有南加州都受益. 我们的区域合作和相互依存意味着一个社区的回收或地下水清理项目整体上减轻了大都会进口供应的负担. 这就降低了运营成本, frees up conveyance capacity to benefit all system users and helps the region adapt to climate change. 这就是为什么大都会支持和激励一些有益的项目和倡议,帮助该地区发展当地供应和保护. 我们投资了1美元.到目前为止,这些项目投入了60亿美元. 要了解成就的概要, 点击这里 and for the full Achievement 报告 in 保护, Recycling and 地下水 Recharge 点击这里.
都市的 本地资源计划 provides incentives for member and local agencies to develop new local projects, 如水循环利用和地下水回收. Metropolitan has provided financial assistance to more than 100 projects across Southern California, 产出大于1.3万亿加仑的循环水和回收地下水. 今天,在两大进口水源严重短缺的情况下,区域可靠性的价值得到了提高. By providing direct funding based on how much water projects produce, 该计划大大提高了他们的经济生存能力.
这些数字说明了一个成功的故事. 在20世纪90年代, 近60%的大都会供水组合是从科罗拉多河和州水项目进口的水. 其余部分来自当地资源. 供应范式模型的转变表明,2035年进口供应占36%,本地资源占64%.
要确保南加州的供水可靠,就需要投资于当地各种来源的供水,并进行广泛的保护.
回收 水
大都会一直通过我们的本地资源计划支持其他公司开发的循环水项目. But with hotter temperatures and drier conditions predicted due to climate change, we’re investing in new and innovative ways to protect and maximize our water. 大都会正在与洛杉矶县环卫区合作开发南加州纯水, 一个循环水项目,每天将生产1.5亿加仑的水,足够500人使用,000个家庭. 该计划目前正在运行一个500,000-gallon-per-day demonstration facility to verify its innovative processes, which could improve efficiencies and reduce costs in water recycling. A fully realized project would be a new source of water for up to 15 million people.
为了进一步支持本地供应,大都会董事会批准了一项 300万美元的年度预算 现场改造项目, 提供财政奖励,鼓励将饮用灌溉和工业系统改为循环水. 激励措施可以帮助支付项目设计的成本, 允许, 与改造相关的建筑成本, 连接费用, 并且需要循环水标识. 到目前为止,该计划已经资助了463个项目地点.

地下水 补充 & 复苏
地下水 provides more than 35 percent of Southern California's drinking water, 使补充和储存程序至关重要. 地下水 basins act as storage reservoirs below the surface of the earth. Although Metropolitan does not own or manage groundwater basins in Southern California, 作为该地区的补充供水者,我们发挥着至关重要的作用. We help replenish the basins and financially support groundwater recovery projects that treat groundwater.
地下水 wells sometime become unusable because of contamination or increased salinity. This leaves water agencies with a choice – they can rely more heavily on imported supplies as a replacement, or they can recover the groundwater by building treatment facilities to remove contaminants or salt. 通过支持地下水回收和补给项目, Metropolitan supports the effort to replenish the region’s natural storage reserves.
大都会还与当地机构合作,通过联合使用和循环储存协议,将进口的地表水储存在地下水盆地,以备短缺时使用. 这些协议创造了与成员机构管理水资源的灵活方式,并允许大都会在机构需求之前将水输送到地下水盆地,并在需要时调用这些供应. 其他管理工具包括水交换和转移项目,这些项目有助于确保该地区未来的水供应.
保护
在过去的40年里, 大都会推动了创新, evolved markets and influenced consumer decision-making to make Southern California more water efficient. 直接回扣等催化剂, 外展及教育, 新技术支持, 倡导新的建筑规范和标准, and development of strategic alliances have contributed to positive and lasting change.
自2009年以来, 大都会和地方水务机构维持了一项长期保护计划,以支持旨在减少用水的州立法. Southern California met the plan’s goal of reducing per capita water consumption by 20 percent by 2020. 今天,持久的变化是显而易见的——消费者的价值观, behaviors and preferences for water-efficient devices have led to significant reductions in water consumption.
这些数字说明了该地区保护188bet棋牌平台的成功. 自1990年以来, consumers have reduced their use of water from 220 gallons per person per day to 129 gallons in 2021. This 38 percent reduction is directly attributed to investments in conservation programs, 行为改变和支持有效用水的立法.
住宅 & 商业回扣
更有效利用水资源的途径是 bewaterwise.com -大都会保护门户网站的小费和回扣. 都市的 regional rebate program for both residents and businesses is administered through 美元SoCal水集市. 访问bewaterwise.com and 美元SoCal水集市 to learn more about 都市的 residential and commercial rebate programs, 激励措施和其他保护计划.
支持创新
Metropolitan also encourages innovation in conservation through a number of incentive programs. 点击 在这里 了解更多关于这些项目的信息.
Partnerships with like-minded resource agencies also spur conservation savings in communities. 例如, 大都会与SoCalGas合作开展了一项节水和节能的联合激励计划,该计划提供高效率产品,如高效率洗衣机, 智能灌溉控制器和低流量淋浴喷头将免费提供给收入合格的房主和服务不足社区的居民, 同时也提供免费安装.
节水奖励计划
We also support innovative conservation efforts in business with re搜索 partnerships and programs like the 节水奖励计划. This regional pay-for-performance initiative is available to all commercial, 工业, 机构, 农业和大型景观消费者,有资格的项目,专注于大都会服务区域内的用水效率.

雨水
每年大约1个.1 million acre-feet of rainfall and 雨水 flows are captured and recharged into local groundwater basins. As drought conditions continue and climate change continues to take hold, t在这里 is a growing interest in developing additional water supply through 雨水 capture and use. 在回应, Metropolitan launched two pilot programs to better understand the costs and benefits of 雨水 capture, 2020年产量和使用情况. 一个程序寻找机会捕获额外的 直接使用的雨水. 另一个是探索额外的雨水 捕获地下水补给. 大都会航空公司总共投入了12美元.500万美元用于这些项目. 收集到的数据将帮助我们评估雨水收集对供水的好处,并为未来的资助战略提供框架.
未来供应行动
大都会还在投资研究,通过创新方法开发未来的当地供水系统. 通过未来供应行动资助计划, 大都会共同资助成员机构的试点项目和技术研究,目的是增加再生水的潜力, 雨水, 地下水和海水淡化. 大都会目前已投资6美元.在二十多项研究中发现了500万. 项目目标包括:
自2013年第一轮融资以来, 大都会参与资助了34项试点试验, 示范研究和白皮书. 研究报告可在此查阅.
可行性研究考察了具有成本效益的消毒处理方法,以满足圣地亚哥县水务局及其分支机构帕德雷大坝市政水区执行的高级水处理规定.
海水淡化
Metropolitan has explored seawater 海水淡化 as a potential new supply since the 1960s, and we even developed and piloted our own thermal distillation technology.
While 海水淡化 technology has been used to treat and recover brackish groundwater for decades, the cost of treating seawater was not historically competitive with other resources. 在过去的十年里, 膜性能的快速提高, energy recovery technology and process design have lowered seawater 海水淡化 costs, 使它, 在某些情况下, 与其他新供应方案竞争.
自2001年以来, 大都会为会员机构发展本地海水淡化项目提供财政奖励, and seawater 海水淡化 became part of our 本地资源计划 in 2014. 大都会正在考虑一个新的区域海水淡化设施,作为其干旱行动项目组合的可能补充.
