在佛罗里达湖Okeechobee以南的大沼泽地农业区的A-2水库上的首次建设工作将于11月开始,此前由美国陆军军团授予菲利普斯和乔丹公司的7980万美元固定价格合同。工程师。

该合同要求沿拟建水库的北部边界建设水库流入/流出管,渗流管和维护路。稍后将授予其他施工的增量,这将使储层的估计总成本在2029年完成后达到35亿美元。

当湖面水位上升和威胁dike that impounds it, the Corps releases excess to the west through the Caloosahatchee River and to the east via the St. Lucie Canal. In recent years, high nutrient levels in those releases have triggered large blooms of toxic algae on both coasts, killing sea life and producing noxious odors.

该水库的建造是为了接收Okeechobee湖过剩,并慢慢将其释放到菲利普斯和约旦也建造的相关雨水处理区。然后,自然处理的水将逐渐被释放到南部穿过大沼泽地,模仿悠闲的“ SheetFlow”,从而创造了历史性生态系统。

Added elements are the foundation and cutoff wall; reservoir embankment, outlet works and inline spillway; and the reservoir inflow pump station. Design of those increments is underway, says Erica Skolte, a Corps spokeswoman. All design will be by the agency except the pump station, which is under design by Stanley-Stantec Joint Venture.

A contract to build the foundation and cutoff wall may be bid sometime in 2022, according to the program's Integrated Delivery Schedule. Two separate contracts for remaining increments will follow, possibly in 2023. The Schedule is not yet approved, so plans are tentative, Skolte says.

“When completed we will have built a 240,000 acre-ft reservoir covering approximately 16-sq miles,” said Col. James Booth, commander of the Corps Jacksonville District. “It will store a volume similar to about a half a foot on Lake Okeechobee.”

大沼泽地基金会首席执行官埃里克·艾肯伯格(Eric Eikenberg)说,水库“至关重要”。“这是恢复工作的皇冠上的明珠。佛罗里达湾和钥匙都需要淡水。

“The reservoir will be the source of the water during the dry season,” he adds. Freshwater flow also will recharge the Biscayne Aquifer and sequester carbon, he adds.

Phillips and Jordan won thecontract2月,南佛罗里达水管理区的相关雨水处理区。该公司将于2023年12月完成两项合同。
