Core Responsibilities

Primary Functions

Inspect new and existing irrigation installations (sprinkler heads, lateral lines, valves, controllers, pumps, and backflow devices) to verify compliance with approved plans, local and state codes, permitting requirements, and agency water-efficiency standards.
Conduct thorough backflow prevention assembly tests, document test results, and issue compliance notices or certification forms to property owners and regulatory authorities following state and local procedures.
Perform functional startup and operational checks on irrigation controllers, sensors, moisture probes and weather-based controllers to confirm programming accuracy, seasonal schedules, and proper sensor integration for water conservation.
Review construction documents, irrigation plans and as-built drawings to verify pipe sizes, lateral layouts, valve locations, and controller zoning against field conditions and permit approvals.
Evaluate sprinkler distribution uniformity and coverage by conducting catch-can tests, pressure measurements and nozzle checks, and recommend nozzle adjustments, pressure regulation or better system design to eliminate overspray and runoff.
Inspect and evaluate pump stations, pressure tanks, suction lines, and well or municipal connections for proper installation, electrical safety, pressure settings and backflow protection, and coordinate with licensed pump technicians as needed.
Identify and document leaks, cross-connections, broken heads, clogged filters, root intrusion and other defects; provide detailed field reports and photo documentation to contractors and property owners for repair tracking.
Verify proper installation and functioning of drip irrigation components including emitters, pressure-compensating devices, filtration, and lateral spacing to ensure efficient water delivery for landscapes and planter systems.
Enforce water conservation ordinances by identifying wasteful irrigation practices (overspray on sidewalks/roads, watering during restricted hours) and issuing warnings, violation notices or repair orders in accordance with municipal codes.
Perform on-site hydraulic checks and basic irrigation system troubleshooting, including measuring operating pressures at zones and valves, testing manifold performance, and recommending repairs or system upgrades.
Coordinate and witness pressure and flow testing required for system certification or permit closeout, and consolidate test data for permit sign-off and project completion documentation.
Provide contractors and property managers with clear corrective action lists, timelines for repairs, and re-inspection expectations to ensure timely compliance and successful permit closure.
Maintain accurate inspection logs, enter inspection results into permitting and asset management systems, and generate standardized inspection reports and compliance certificates for stakeholders and permitting agencies.
Collaborate with plan review staff during permit processing to flag potential field inspection issues, clarify design intent, and offer practical construction or sequencing recommendations to avoid rework.
Participate in pre-construction meetings and on-site pre-installation walkthroughs to align inspectors, contractors, designers and owners on inspection requirements, critical inspection points and acceptance criteria.
Inspect irrigation installations on new construction, retrofit projects, sports fields, parks, golf courses and commercial landscapes to ensure system performance and longevity under varying site conditions.
Facilitate and document re-inspections after remedial work, confirming that corrective actions were implemented and that systems meet all required specifications before final approval or water service activation.
Provide technical guidance to contractors and property owners about best practices for water-efficient irrigation design, component selection (nozzles, pressure regulators, controllers) and routine seasonal maintenance to reduce future violations.
Track and report recurring issues, patterns of non-compliance or system failures to supervisory staff to inform training needs, specification updates and city/county program improvements.
Use basic GIS/mapping and mobile inspection tools to geo-locate inspections, attach photographic evidence, and update asset records for institutional memory and utility management.
Stay current with changes to irrigation codes, water agency regulations, industry standards (Irrigation Association guidance) and new technologies that impact inspection criteria and enforcement practices.
Ensure safe work practices on job sites, coordinate with other inspectors and contractors to minimize conflicts, and follow employer OHS/OSHA requirements when working around trenches, excavation, electricity and traffic.
Provide occasional public-facing education at community outreach events or conservation workshops to promote efficient irrigation practices, rebate programs, and compliance expectations.

Secondary Functions

Schedule inspections, coordinate re-inspection appointments, and manage daily itineraries to optimize field efficiency and customer service response times.
Train and mentor junior inspectors and field technicians on inspection protocols, report writing, equipment use, and regulatory requirements.
Support data quality initiatives by validating inspection entries, improving checklist templates, and suggesting standardized field-coding for easier analytics and reporting.
Maintain and calibrate field test equipment (pressure gauges, flow meters, catch cans, backflow test kits) and manage replacement ordering and inventory.
Participate in cross-departmental meetings with permitting, plan review, and water conservation teams to align inspection criteria and enforcement strategies.
Assist with enforcement workflows by preparing follow-up letters, compliance orders, and evidence packages for administrative hearings or contractor performance reviews.
Collect cost and time metrics for inspections to help refine workload models and support budget or staffing requests.
Contribute to seasonal scheduling for irrigation audits and conservation inspections when demand spikes (spring start-up and summer peak).
Review and provide feedback on proposed irrigation specifications and master plans to help preempt common installation deficiencies.
Aid in pilot programs for new inspection technologies (mobile apps, meter integrations, remote sensor review) and provide user feedback for continuous improvement.
