Scrubber Sludge Disposal System Clause Samples

Scrubber Sludge Disposal System. Effluent slurry is carried from the Plant to the sludge disposal pond by a 16” pipe. The suspended solids settle to the pond bottom and the clear water is pumped back to the Plant by two 3,020 gallon per minute pumps. One pump acts as a spare. The pond return pipe is 18” in diameter. The sludge disposal pond (called Areas 5 and 6) is approximately three miles southeast of the Plant. There was a two phases in the development of this pond. Phase 1 required the construction of one dam 70’ high and 400’ in length. The capacity of Phase 1 is 8,000 acre-feet and it lasted approximately 13 1/2 years. The development of Phase 2 required that the original dam be raised to 130’ in height and increased to a length of 3,000 feet. A saddle dam was also added. The saddle dam varies in height, with a maximum height of 50’ and a total length of 3,300 feet. The capacity of Phase 2 is an additional 8,900 acre-feet and it will last approximately 14 1/2 years, for a total life of 28 years. The sludge disposal pond design took into account a permit requirement for minimum seepage, by providing low permeability soil blankets where exploration defined porous outcrops or high permeability soils.
