巴拿马运河管理局雄心勃勃的200亿美元努力解决了历史悠久的水道淡水供应量的衰落，并在两年内启动了新的招标。该机构现在已经签约了美国陆军工程兵团，以帮助定义即将到来的BID套餐的工作范围 - 投标人试图降低项目风险。

In its previous request for qualifications issued in 2020, the authority said the contractor would be responsible for program concept, design and construction—which was set to include identifying sites where component projects would be built, and managing needed investigations, surveys and studies, including those for hydrological, climatic and environmental conditions.

2021年6月，当局宣布将在有250多个有兴趣参与的承包商收到的答复之后，完全改进招标过程。

风险水平

“我们在资格预审过程中与有兴趣的公司的对话使我们能够更好地了解该行业愿意假设的风险水平，并改善招标过程，以确保运河运营所需的数量和质量以及人口的数量和质量几十年来。

“军团是我们可以与之交往的明确合作伙伴，以协助生产我们可以投标的项目组合”，”管理局副行政官Ilya Espino de Marotta告诉ENR。18luck官网新利luck

The agency’s water management system program will consist of a portfolio of projects that would guarantee an adequate water supply, taking into account sustainable development, growth projections and the impact of climate change on the waterway. The authority and the Corps have conducted virtual meetings since the $11.4-million contract was signed last November. In-person meetings and inspections are planned for this spring.

据当局称，该军团计划于2024年完成工作，然后发布出价包。Espino de Marotta说，它将2028年作为项目组合的完成目标设定，尽管这项工作可以加速。18luck官网

巴拿马运河的行动取决于盖顿湖中足够的水，可以通过大量的船只，需要多达50英尺的草稿。该湖是一个较大的水域的一部分，它也是大约200万人的淡水的主要来源，这是该国总人口的一半。

多年的干旱状况导致湖中历史上的水位低，要求船只的汇量在2019年限制为44英尺。一个容器船可以为每增加一只截止步骤携带约300个容器。

In a 2020 report, the authority said rainfall in 2019 was 20% below the historic average. The $5-billion expansion of the canal, completed in 2016, also put pressure on water resources. About 50 million gallons of fresh water are lost through the locks to the Pacific and Atlantic oceans.

Moving Forward

作为回应，当局发起了一系列的努力来减轻水分流失，包括减少运河过渡的数量，限制Gatun大坝的水力发电生产以及尽可能从先前通道中重复使用水。还调整了大坝溢洪道以提高湖水水平。

The authority also introduced a permanent fresh water surcharge of $10,000 in early 2020 on all vessels longer than 125 ft. It includes a fee that increases in relation to water levels in the canal. The higher cost for passages helps limit the number of transits during periods of low water availability.

For the water program, contractors now will be presented with a conceptual design of the system to reduce the level of risk, improve cost estimates and enable better technical evaluation of proposals.

该计划将包括诸如创建新水库，建造新的水处理厂以及从巴拿马运河盆地附近河流盆地的新来源的元素。
