FAQ

What work fits NAICS 221310?
  • Emergency repair and isolation of distribution mains to restore service, including valve operation, temporary bypass pumping, and pressure testing.
  • Design and rehabilitation of distribution pipeline segments with cleaning, lining or replacement, pressure testing, and as-built drawings for acceptance.
  • Installation or replacement of pump station equipment and controls with startup testing, vibration reports, and operations training for plant staff.
  • Telemetry and SCADA upgrades including PLC programming, sensor installation, system integration, and delivery of interface documentation and O&M manuals.
When is NAICS 221310 a weak fit?
  • Stormwater conveyance and detention system projects - focus on runoff management, culverts, and detention basins rather than potable supply or irrigation distribution.
  • Groundwater well drilling and well construction contracts - drilling and well completion without associated treatment, distribution, or storage works.
  • Wastewater collection and treatment services - sanitary sewer lines and treatment plant processes fall outside potable supply and irrigation system scope.
What solicitation language points to NAICS 221310?
  • Performance requirements specify hydraulic performance metrics such as pressure or residual disinfectant thresholds and allowable leakage or unaccounted-for-water limits.
  • Deliverables call for as-built pipeline drawings, pressure test certificates, reservoir inspection reports, and O&M manuals.
  • Labor categories list water treatment operators, pump technicians, pipeline crews, and SCADA programmers with specified certifications.
