Key Responsibilities and Required Skills for Irrigation Controller

🎯 Role Definition

The Irrigation Controller is responsible for programming, maintaining, and troubleshooting irrigation control systems (including smart/ET and cloud-based controllers) to deliver efficient landscape irrigation across municipal, commercial, residential, or agricultural sites. This role manages controller schedules, integrates sensor and weather data, diagnoses electrical and hydraulic issues, supervises preventive maintenance, coordinates repairs with vendors, and documents water use to meet conservation and regulatory goals. The ideal candidate combines hands-on mechanical and electrical aptitude with strong record-keeping, customer service, and water-management knowledge.

Core Responsibilities

Primary Functions

Program and maintain multiple irrigation controllers (including Rain Bird, Hunter, Toro, Netafim, and cloud-based systems) to ensure accurate run times, seasonal adjustments, and compliance with site-specific water budgets; update schedules based on plant needs, weather, and municipal restrictions.
Configure and optimize smart/ET-enabled controllers and weather station integrations to automatically adjust irrigation cycles for evapotranspiration, rainfall, and real-time sensor input to maximize water efficiency.
Perform routine diagnostics and electrical troubleshooting on controllers, clocks, relays, solenoids, and control wiring using multimeters and electrical test equipment to isolate and repair faults safely.
Inspect, repair, and replace irrigation valves, solenoids, lateral lines, sprinkler heads (rotor and spray), drip systems, manifolds, and fittings; perform nozzle adjustments, arc settings, and pressure regulation to maintain uniform coverage.
Test, calibrate, and maintain flow sensors, pressure transducers, master valves, and pump station controls; monitor flow data for anomalies and initiate repairs when abnormal consumption is detected.
Conduct scheduled preventive maintenance programs for controllers and associated hardware—verify battery backups, clean terminals, flash memory updates, and firmware upgrades for smart controllers.
Respond to emergency irrigation failures and service requests (e.g., mainline breaks, valve malfunctions, frozen pipe protection) with prompt diagnostics, temporary measures, and permanent repairs while minimizing landscape damage.
Lead site audits and irrigation evaluations (including catch-can tests and distribution uniformity assessments) to identify inefficiencies, recommend retrofits, and produce actionable reports for property managers or owners.
Coordinate and schedule contract technicians, electricians, and irrigation vendors for specialized repairs, backflow testing, or pump repairs; provide clear scopes of work and oversee contract completion and quality.
Maintain accurate, up-to-date records of controller configurations, run-time histories, repairs, parts used, and water usage reports in CMMS, proprietary controller platforms, or spreadsheets; prepare monthly water-use summaries for stakeholders.
Ensure all backflow prevention assemblies associated with irrigation systems are identified and scheduled for testing, and coordinate with certified backflow testers to maintain compliance with local codes.
Implement and monitor seasonal changeover procedures (spring start-up and winterization) including draining lines, blowouts, anti-freeze protection where applicable, and restarting schedules with appropriate zone testing and adjustments.
Educate property staff, landscape crews, and clients on controller operations, seasonal adjustments, and best-practice water conservation techniques; provide training on remote controller apps and manual override procedures.
Integrate and maintain remote monitoring and telemetry systems (SCADA or cloud-based dashboards) to allow centralized controller management, event alerts, and historical analysis of irrigation performance.
Use GIS, site maps, and as-built drawings to maintain an accurate valve, controller, and sensor inventory; update location-based records to support fast troubleshooting and repair.
Perform routine vehicle and tool maintenance for service vans or trucks, maintain an organized inventory of parts, and requisition replacement components to minimize downtime.
Implement and enforce occupational health and safety standards during all irrigation work, including lockout/tagout procedures for electrical repairs, safe operation of compressors during blowouts, and PPE use for crew and public safety.
Analyze water meter data and utility bills to detect leaks, unauthorized use, or irregular trends; prepare and present corrective action plans to facilities managers or clients.
Manage small capital projects and system upgrades such as converting spray to drip zones, installing moisture sensors, or upgrading to smart controllers—prepare material lists, cost estimates, and coordinate installations.
Troubleshoot and maintain pump stations associated with irrigation systems: check starters, pressure switches, VFD settings, and coordinate with licensed electricians as needed.
Ensure irrigation systems comply with local ordinance restrictions, drought mandates, and applicable environmental regulations, documenting adjustments and communicating changes to stakeholders.
Lead post-installation and commissioning checks after new controller or system installs—verify every zone sequence, run times, pressure, and sensor response before turnover to operations.
Analyze landscape water requirements and recommend schedule optimization, zone reconfiguration, or hardware retrofits to reduce water use while protecting plant health.
Serve as the on-site liaison with landscape architects, contractors, and municipal inspectors during inspections, permitting, and corrective action plans related to irrigation infrastructure.

Secondary Functions

Maintain spare parts inventory and vendor relationships to ensure rapid access to controllers, solenoids, nozzles, and valves for emergency service.
Create and maintain standard operating procedures (SOPs) for controller programming, troubleshooting workflows, and seasonal maintenance checklists.
Support sustainability programs by identifying and implementing water-saving projects and tracking outcomes against conservation targets.
Provide input into budgeting for irrigation repairs, replacements, and upgrades; prepare cost estimates and justify capital requests with ROI and water-savings projections.
Assist in cross-functional projects such as landscape renovation, stormwater management, and utility coordination when irrigation impacts other site systems.
Participate in on-call rotation for after-hours irrigation emergencies and provide clear incident documentation and follow-up remediation plans.
