Core Responsibilities

Primary Functions

  • Lead the end-to-end design of pressurized and gravity-fed irrigation systems (sprinkler, drip/micro-irrigation, center-pivot, subsurface) including water demand analysis, hydraulic calculations, pipe sizing, pressure-compensating device selection, and emitter spacing to meet crop and site requirements.
  • Prepare detailed engineering drawings, specifications and bill of quantities using AutoCAD Civil 3D and GIS tools, ensuring constructability, compliance with local codes, and integration with drainage and land grading plans.
  • Perform water balance and scheduling analysis including crop coefficient (Kc) studies, evapotranspiration (ET) calculations, soil water retention modeling and automated scheduling recommendations to optimize irrigation timing and volumes for water efficiency and yield improvement.
  • Size, select and specify pumps, motors, valves, filtration systems and fertigation equipment; generate pump curve analyses, net positive suction head (NPSH) checks and energy efficiency assessments to reduce operating costs.
  • Conduct hydraulic modeling and flow analysis (steady-state and transient) to evaluate network performance, pressure zones, surge protection, and mitigation measures for long pipelines and complex distribution systems.
  • Develop and supervise site investigations, topographic surveys and soil infiltration/permeability testing to inform design parameters, intake structures and drainage solutions.
  • Lead tendering processes: prepare tender documents, evaluate contractor bids, assist in selection, and administer contracts, including change order review and progress claims for irrigation construction works.
  • Oversee construction supervision and commissioning, coordinate contractor activities, conduct quality assurance inspections, witness performance tests (pressure tests, flushing, fertigation trials), and issue completion certificates.
  • Implement and configure irrigation automation systems including controllers, remote telemetry units (RTUs), PLCs, and SCADA integrations for remote scheduling, telemetry, alarm management and data logging.
  • Design and implement irrigation monitoring programs using soil moisture sensors, flow meters, pressure transducers, weather stations and telemetry to validate water use, detect leaks, and refine schedules.
  • Prepare water resource assessments, environmental impact screenings and permitting documentation for water take licences, wetland protections, and stormwater management compliance.
  • Develop preventative maintenance plans, operating manuals and troubleshooting guides for irrigation systems to minimize downtime and extend asset life, and train operations staff and contractors on correct procedures.
  • Lead irrigation audits and system performance reviews to identify leaks, pressure imbalances, inefficiencies and retrofit opportunities such as pressure regulation, variable frequency drives (VFDs) and evapotranspiration-based controllers.
  • Provide cost estimates, lifecycle cost analysis and whole-of-project economic justifications including O&M cost forecasting, energy consumption projections and water savings ROI for proposed irrigation solutions.
  • Coordinate integrated drainage and erosion control designs, managing tailwater recovery systems, sediment basins and recycled water reuse schemes where applicable.
  • Liaise with agronomists, landscape architects, growers and municipal stakeholders to align irrigation designs with crop plans, planting schedules, turf/wastewater reuse strategies and community expectations.
  • Ensure compliance with local, regional and national regulations, standards and best-practice guidelines (ASABE, ISO, EPA/local water authorities) and prepare documentation for regulatory approvals.
  • Develop and manage project schedules, risk registers and progress reporting; proactively identify technical and operational risks and implement mitigation measures to maintain timelines and budgets.
  • Conduct performance-based testing and data analysis following commissioning — analyze flow, pressure and application uniformity test results (CU, DU) and fine-tune system settings to achieve target uniformity and efficiency.
  • Support capital planning and asset management activities including condition assessments, prioritization of upgrades, and preparation of funding proposals or grant applications for irrigation infrastructure projects.
  • Drive continuous improvement by evaluating new irrigation technologies — low-pressure systems, precision fertigation, sub-surface drip, remote sensing, soil-moisture-based controllers — and create pilots and implementation roadmaps.
  • Prepare clear, recruiter- and client-facing technical proposals, reports, maintenance plans, and training materials; present findings to stakeholders and deliver technical briefings and handover packs.

Secondary Functions

  • Provide ad-hoc technical support and troubleshooting for operations teams during peak irrigation seasons and emergency responses.
  • Contribute to interdisciplinary teams on water resource planning, sustainability initiatives and climate adaptation strategies for landscape and agricultural clients.
  • Assist business development with technical input for proposals, client meetings and tender clarifications to win irrigation and water-efficiency projects.
  • Collect, clean and analyze field telemetry and sensor data to inform continuous optimization of irrigation schedules and detect anomalies.
  • Support interdisciplinary R&D or pilot projects testing new irrigation technologies, sustainability measures, or data-driven irrigation management tools.
  • Mentor junior engineers, technicians and interns; provide on-the-job training in design standards, field testing procedures, and safety practices specific to irrigation works.
  • Participate in community outreach, stakeholder consultations, and client education programs to promote best practices in water-use efficiency and sustainable irrigation.
  • Maintain up-to-date documentation libraries, CAD/GIS templates, and standard operating procedures for quick reuse and knowledge transfer across projects.
