Using 81% less energy, the new 25w LED full cutoff wall pack produces equivalent mean luminaire lumens as the 100w pulse-start metal halide full cutoff wall pack.
A concrete cutoff wall in the middle of the dam would definitely solve the problem.
The dam, built in 1925, consists of stone masonry with concrete training walls and earth embankments at each abutment, QCC's design repairs of the deteriorated dam consisted of an upstream concrete facing, apron and short cutoff wall to seal the existing stone dam from leakage, and reduce seepage potential under the structure.
Gary, IN, was awarded a $7,000,000 increment as part of a $9,297,757 firm-fixed-price contract for construction of a Soil-Bentonite Cutoff Wall at the CUP McCook Reservoir Site.
Completion of the cutoff wall paved the way for the water quality improvement program and led to an estimated savings of $23 million in avoided impacts to the nearby community versus use of conventional dewatering.
HPA's scope of work for the approximately three-year-long project will include demolition of two existing culverts, placing lengths of cutoff wall to close the existing gaps in the existing cutoff wall at the culvert locations, placement of new cast-in-place concrete culvert structures with gates and control systems at the same locations, and restoring the embankment.
