  • SS6.02 Alhaja Pump Station Rehabilition

    Total Project Cost: $180,507
    Project Number:  CWW3APS01
    Funding Sources: 2004 Sewer Revenue Bonds
    Completion Date: June 2009
    Managing Dept.: Regional Wastewater Reclamation
    Project Map: GIS Map

    This project installed a new fiberglass bottom in the wet well, removed the failing brick top cone, and installed a new precast concrete upper section and a new precast concrete flat top. Both the old brick and new concrete were lined with a fiberglass lining to prevent future corrosion damage. New stainless steel guide-bars were installed so the pumps can be removed and repaired without workers making a confined space entry into the wet well. The existing pumps were reinstalled in the new manhole. The project also included the addition of lights for nighttime inspection and upgraded the electrical and SCADA capabilities to assure up to date standards. A new valve vault, ductile iron discharge piping and
    valves were also installed.
