Core Responsibilities

Primary Functions

Conduct routine and targeted field inspections of water treatment plants, pumping stations, reservoirs, storage tanks, distribution mains, hydrants, service connections, and wastewater tie-ins to verify operational integrity, structural condition, and regulatory compliance with federal, state, and local drinking water and wastewater standards.
Collect bacteriological, chemical, and physical water samples using approved sampling procedures and chain-of-custody documentation; perform common field tests (free/chlorine residual, pH, turbidity, conductivity) and accurately record, interpret, and communicate field results to supervisors and lab partners.
Perform cross-connection and backflow prevention device inspections: test assemblies, tag and certify compliant devices, document failures, coordinate repairs or replacements with property owners and licensed contractors, and maintain backflow device inventories.
Review construction plans, specifications, and as-built drawings for new mains, service connections, treatment modifications, and point-of-entry/point-of-use designs to ensure they meet code, permit conditions, and public health standards prior to approval.
Enforce regulatory requirements (e.g., Safe Drinking Water Act, state DPH rules) by issuing Notices of Violation, documenting non-compliance findings, developing corrective action plans, and following through on enforcement escalations when necessary.
Conduct sanitary surveys and vulnerability assessments for sources, wells, intakes, and distribution networks; identify potential contamination pathways and recommend source protection or operational changes to reduce risk.
Coordinate with certified laboratories to manage sample submittal, ensure analytical methods align with monitoring requirements, verify chain-of-custody, review laboratory results for exceedances, and escalate confirmed positives to management and health authorities.
Investigate customer complaints and service-line incidents (discolored water, low pressure, taste/odor concerns), perform targeted tests, identify root causes, and recommend remediation such as flushing, repairs, or system adjustments.
Manage and document boil water advisories, do-not-drink notifications, and other public health notifications: draft public messaging, coordinate with the health department and communications teams, and track community outreach outcomes.
Monitor disinfection practice and residual levels at entry and throughout the distribution system; advise operators on dosing adjustments and follow-up sampling to ensure compliance with minimum residual and CT requirements.
Inspect construction activities and contractor work in the water system: verify materials, trenching and backfill practices, bacteriological post-construction disinfection, sleeve installations, and restoration to ensure compliance with standards and permits.
Maintain accurate inspection records, compliance logs, enforcement actions, and sampling data in electronic databases, CMMS, or GIS systems; prepare and submit inspection and compliance reports to management and regulatory agencies on periodic schedules.
Support permit administration by reviewing monitoring plans, sampling schedules, deviation reports, variance requests, and permit renewal documentation to ensure complete and timely regulatory submittals.
Participate in emergency response for contamination events, pipe breaks, main repairs, natural disasters, or any incident affecting water quality; perform immediate field assessments, coordinate sampling and remediation, and document event actions for after-action reviews.
Use GIS and asset management tools to map infrastructure, prioritize inspection routes, analyze complaint clusters spatially, and support capital planning and source protection zoning.
Conduct lead service line inventories, inspect replacement work, verify material compliance (lead-free requirements), and document progress toward lead reduction goals in accordance with federal and state policy timelines.
Provide technical coaching and on-the-job training for water operators, seasonal staff, and contractors on best practices for sampling, chlorination, cross-connection control, confined space, and safety protocols.
Review and approve disinfection, flushing, and commissioning plans for new or repaired mains; witness post-construction bacteriological testing and clearance prior to returning assets to service.
Prepare detailed inspection narratives, photographic documentation, violation notices, and technical memos that can be used for enforcement, public records, and regulatory audits.
Track program performance metrics and KPIs (sample completion, violations resolved, response times, inspection coverage) and prepare quarterly and annual summaries to inform leadership and regulatory stakeholders.
Coordinate with engineering, planning, and capital project teams to ensure inspection findings are incorporated into rehabilitation and replacement planning and advise on risk-based prioritization of infrastructure projects.
Maintain field safety and compliance: implement confined space entry procedures, ensure appropriate PPE use, enforce lockout/tagout during inspections where necessary, and complete incident reports when required.
Engage with the public, elected officials, and community groups to explain inspection results, water quality findings, regulatory actions, and the importance of infrastructure investment to protect public health.

Secondary Functions

Support program administration including scheduling inspections, maintaining certifications and training logs, and ordering field supplies and sampling kits.
Assist in the development and update of inspection checklists, SOPs, and sampling protocols to reflect current regulations and agency best practices.
Participate in multi-agency working groups, stakeholder meetings, and interdepartmental coordination to streamline permitting, emergency response, and public outreach.
Provide photographic and GIS documentation for asset condition assessment and assist in prioritizing capital improvements based on inspection findings.
Support mock audits, regulatory inspections, and data requests by assembling inspection records, chain-of-custody logs, and corrective action documentation.
Contribute to community outreach events and educational campaigns on water conservation, cross-connection hazards, and household water safety best practices.
