Opportunity Snapshot: Pompey’s Pillar Iron Filter Tanks
Federal Contractors Lab community — here’s a real-world SOW worth studying.
This requirement focuses on restoring proper operation of a drinking water treatment system by replacing and rehabilitating key treatment components.
Scope of Work includes:
✅ Removal and replacement of three existing iron filtration units
✅ Replacement of exhausted filter media
✅ Evaluation, rehabilitation, or replacement of hydropneumatic tanks
✅ Startup and system reactivation
✅ Verification of aeration and backwash functionality
✅ Adjustment of air educator settings
✅ Confirmatory sampling to ensure treatment objectives and regulatory requirements are met
Why this matters:
The Montana Department of Environmental Quality identified that the treatment plant is not operating as designed due to underperforming and unmaintained equipment. The system is experiencing ineffective iron and manganese removal, inconsistent chlorine demand, and unreliable disinfectant residuals.
This is a strong example of a public works / water treatment opportunity where contractors need to understand both the technical requirement and the compliance driver behind the work.
Key contractor takeaways:
- This is not just a tank replacement job.The contractor must understand water treatment performance, oxidation, filtration, pressure systems, and startup verification.
- Certifications matter.The SOW calls for potable-water-compatible equipment, including NSF/ANSI 61 certified tanks or approved equals.
- Existing site conditions matter.Connections and dimensions must be coordinated with the current piping to minimize modifications.
- Documentation matters.Manufacturer certifications and pressure testing documentation are required.
- Regulatory context matters.The work is tied to correcting DEQ-identified deficiencies and restoring compliant water treatment operations.
Potential NAICS areas to research:
🔹 237110 — Water and Sewer Line and Related Structures Construction
🔹 221310 — Water Supply and Irrigation Systems
🔹 238220 — Plumbing, Heating, and Air-Conditioning Contractors
🔹 333310 / equipment-related categories
may also be worth checking depending on how the solicitation is issued
Go/No-Go questions for contractors:
Can you supply and install potable water pressure vessels?
Do you have experience with iron and manganese filtration systems?
Can you document NSF/ANSI compliance?
Can you perform startup, testing, and system verification?Do you understand backwash procedures, aeration, and hydropneumatic tank function?
This is the type of opportunity where a compliant proposal should clearly show technical capability, equipment compliance, past performance with similar systems, and a practical plan for restoring the system to proper operation.
Study the SOW, identify the compliance requirements, and think through what the government needs to see before trusting a contractor with this work.
