Description

1. 1. Work of this Contract comprises of the following:
    1. Install a concrete apron at the Cell 5 effluent withdrawal structure, add a gate to the fence for access, and replace the Cell 5 outlet manhole.
    2. Prepare Cell 5 to serve as temporary storage by scarifying and recompacting the clay liner.
    3. Install a temporary bypass system to route effluent from Cells 1 and 2 to Cell 5 during construction.
      1. Isolate Cells 3 and 4 with line plugs, set up pumps and pipelines from Cell 1 & 2 to Cell 5.
    4. Transfer the wastewater from Cells 3 & 4 to Cell 5 and transfer any remaining sludge from Cells 3 & 4 to Cell 5.
      1. Estimated maximum sludge volume to be transferred is 80 bone try tonnes (BDT’s).
    5. Strip the top 150mm clay liner layer from Cells 3 and 4, and condition as required.
    6. Remove the berm between Cells 3 and 4 to form one combined cell and lower the floor elevation in Cell 3 to match the floor elevation in Cell 4.
      1. Reuse suitable clay for backfilling, grade the bottom to a uniform level, and ensure proper compaction at perimeter tie-ins.
        
        The top 150mm of clay liner is considered contaminated and shall be re-used for fill in the newly formed cell.
        
        Regrade, condition, and recompact Cell 4 berms to a uniform 3:1 slope and level floor to ensure successful liner installation.
    7. Install a new HDPE liner system across the combined cell.
      1. Ensure the new facultative Cell 3/4 subgrade meets the manufacturer’s HDPE liner installation requirements.
        
        Vent and drain the subgrade, place geotextile fabric, and install 80 MIL HDPE liner with heat-welded seams.
    8. Replace existing sewer pipe between MH-36 and MH-37. Install service line from the replaced sewer pipe to MH-38.
