24-504 - Interim Long-Term Bio-Solids Blind Brook Water Resource Rec. Facility, Rye, N.Y.

The work under this contract consists of providing all necessary labor, materials, equipment, and all other items required to implement interm sludge thickening at the Blind Brook WRRF in Rye, New York.  The Blind Brook plant currently has no means of thickening sludge at the treatment plant so the implementation of interim sludge thickening is proposed as a solution to allow the inspection of the 8-inch steel sludge forcemain to the Port Chester WRRF and allow for the future rehabilitation or replacement of the forcemain, which was installed in 1976.  Sludge produced at the Blind Brook WRRF is currently pumped to the Port Chester WRRF for thickening, hauling, and ultimate disposal.  The forcemain is approximately 16,000 LF in length and has 20 access manholes along the route and has suffered serveral breaks that have necessitated shurdown of the sludge transfer to the Port Chester WRRF.  During these temporary shutdowns, un-thickened sludge has been hauled by truck from B/lind Brook WRRF to the Port Chester WRRF; however, the hauling of dilute sludge cannot keep up with the sludge production at the Blind Brook Plant, which makes long-term implementation unsustainable.  (Bid range $ 720,000.00 to $ 800,000.00).
