SAA #1600-2011-0110-R5

Document Description: The project involves repair of two existing 7-foot wide by 7-foot wide reinforced Concrete Boxes (RCB) used to convey flows from Weir Pond 3 to Weir Pond 4, and the construction of a 600 concrete headwall around each opening of the RCB structures. Additionally, an existing 48-inch diameter pipe will be internally retrofitted with a supplemental structure (insertion of a sleeve within existing pipe) to regain the lost capacity of the existing structure, and the construction of a new 90-inch drain-tube to allow for the transfer of surface water from Weir Pond 3 to Weir Pond 4. The two existing 42-inch diameter drain-tubes connecting Weir Ponds 3 and 4 will be decommissioned and left in place.
