Attachment_5_Seven_Bays_Lift_Station_Design_Drawing.pdf

This is a technical drawing document depicting lift station details for a pump vault renovation project. The drawing shows a comparison between an existing pump vault (NTS - Not To Scale) and a proposed pump vault configuration, with both presented in plan and elevation views.

The proposed work involves the demolition and replacement of all existing pump components within the confines of an existing wetwell. Key modifications include: removal of existing 1-1/4" gate valves, control panel, and conduits; installation of a new 3" SCH 80 PVC discharge line with KDR-N-SEAL waterproof connectors; replacement of vertical check valves, galvanized pipes, and stainless steel discharge pipes; installation of new pumps within a duplex guide rail system; addition of high-level alarm and liquid level sensor equipment; and removal of the lag pump assembly. The elevation notes reference specific measurements (EL. 1288 series elevations) and indicate that wet well dimensions and float elevations are approximate pending actual equipment sizing verification. A critical constraint noted in red text specifies that all work performed shall be within the existing wetwell. The drawing is labeled as Sheet C.3 (Lift Station Details) and includes a revision block dated 5/17/2025, indicating this is a construction or design document for a municipal or utility infrastructure project.
