Document Description
The Sump of 154 Low-Flow Outlet Replacement Project consists of excavating to a depth of 3 ft to remove the existing buried 135 ft long 12 inch diameter low-flow outlet pipe and replace it with a new 12 inch diameter, high-density polyethylene (HDPE) pipe on the same general alignment. All HDPE joints would be fusion welded to provide a monolithic, non-corrodible pipe. A new flapgate would be installed on the discharge end of the low-flow outlet pipe. The Project also includes installation of a 6 inch diameter polyvinyl chloride (PVC) side drain to connect the large flip bucket with the low-flow outlet strucure. The purpose of the side drain is to facilitate circulation of standing water in the large flip bucket, and thus reduce mosquito breeding. The 6 inch side drain would be installed between the western wall of the conscrete flip bucket discharge structure and the headwall of the low-flow discharge structure. No work will occur within the existing Rock Slope Protection (RSP) adjacent to the discharge structures, and now new RSP will be added.
