Abstract: A method of restoring a lake that has a high saline level is disclosed herein. In order to restore the lake, a series of concentric dikes or levees are provided that separate the lake into a plurality of smaller lake sections, each having a water surface. The smaller lake sections include an outer lake section which is next to the periphery of the lake and one or more inner lake sections. Each dike and each smaller lake section water surface have an elevation. Water is flowed from an influent source to the outer lake section and then to each of the inner lake sections. The outer lake section surface has a higher elevation. The inner lake section surfaces have cascading lower surface elevations. At a central area, a breathing brine area is provided that is surrounded by the smaller lake sections to provide an area that can be used to concentrate brine. The smaller lake sections can have differing salinity levels for sustaining diverse marine and plant life.

Abstract: Make-up water derived from an on-shore treatment facility is returned to a slurry processing unit on board a dredge by means of a water supply pipeline floating alongside a slurry delivery pipeline that conveys dredged material to the on-shore treatment facility. After separation from the slurry solids, the return water is pressurized to a transport pressure at the treatment facility with a centrifugal pump and then boosted to the desired working pressure once aboard the dredge. This two-stage pumping and re-cycling process reduces the amount of clear make-up water needed for proper operation of the slurry processing unit by more than 50%. This has resulted in a substantial reduction in the overall cost of remediation by reducing the amount of water that must be cleaned prior to disposal.
