Statement of Work (SOW)

To replace three existing iron filtration units, replace exhausted filter media, rehabilitate associated treatment components, and reactivate the system to restore proper operation of the Pompey's Pillar drinking water facility. This work is necessary to correct deficiencies identified by the Montana Department of Environmental Quality (DEQ) regarding underperforming equipment.

• Removal and replacement of three existing iron filter vessels.

• Replacement of exhausted filter media.

• Rehabilitation or replacement of two hydropneumatic tanks.

• Reactivation of the system, including startup procedures, verification of aeration and backwash functionality, and adjustment of air eductor settings.

• Confirmatory sampling to ensure treatment objectives and regulatory requirements are met.

• The system must meet DEQ-identified performance objectives and regulatory requirements.

• Manganese concentrations at the clearwell effluent should be at or below the recommended level of 0.05 mg/L.

• Iron concentrations should be addressed.

• Chlorine demand should be consistent, leading to reliable disinfectant residuals.

• Not explicitly stated in the provided text, but implied to be at the Pompey's Pillar drinking water facility.

• Iron Filter Vessels:

  • (3) Pressure iron filter tanks/vessels.
  • Designed for potable water use.
  • Sized to meet existing system flow and pressure requirements.
