The work includes, but is not limited to, the following: A. Construct a duplex pump station for a housing cluster currently being served by a failing community lagoon system. 1. Pump station shall be complete with a wet well and valve vault. 2. Provide pumps, controls, alarms, piping, appurtenances, and electrical work for pump station. 3. Provide backup portable sewage pumping system. B. Connect pump station to existing housing cluster sewer collection system. 1. Construct 3 Air Relief Valve and Manholes 2. Construct 2 standard depth manholes. 3. Construct approximately 280 feet of 8-inch PVC gravity sewer main. 4. Abandon 2 existing manholes. C. Construct a sewer force main between constructed pump station and existing pump station. 1. Sewer force main will consist of approximately 5,328 feet of 4-inch of HDPE DR 17 Sewer Force Main pipe. 2.
