Key Responsibilities and Required Skills for Water Truck Driver

🎯 Role Definition

The Water Truck Driver (also called Water Truck Operator or Water Tender) is responsible for safely operating a tanker-style vehicle to transport, distribute, and apply water at construction sites, mining operations, landfills, and public works projects for dust control, compaction, hydroseeding support, and fire suppression. The role requires a CDL driver with tanker endorsements, strong safety awareness, and the ability to perform vehicle inspections, basic maintenance, accurate record-keeping, and clear communication with site supervisors and dispatch. Successful candidates demonstrate proven heavy vehicle handling, pump and valve operation, route and site coordination, and adherence to DOT and environmental regulations.

Core Responsibilities

Primary Functions

Operate water tanker trucks (typically 1,500–10,000+ gallon capacities depending on site) in a safe, defensive manner to haul, deliver, and apply water for dust suppression, compaction, hydroseeding, and erosion control per site plans and supervisor instructions.
Complete thorough pre-trip, en-route, and post-trip inspections of chassis, tank, pumps, hoses, valves, lights, brakes, tires, and safety gear; document defects and coordinate repairs to ensure vehicle safety and regulatory compliance.
Load and unload water at municipal fill sites, hydrants, ponds, or temporary fill stations using hoses, pumps, and fittings; ensure secure connections, backflow prevention, and proper metering of volumes.
Operate onboard pumps, water cannons, spray bars, foam systems or hose reels to distribute water uniformly for dust control, soil compaction, or firefighting assistance, adjusting pressure and spray patterns as required by site conditions.
Maintain accurate DOT logbooks, driver vehicle inspection reports (DVIR), trip manifests, water delivery tickets, and electronic hours-of-service (ELD) records; submit required paperwork to dispatch and project management on schedule.
Follow prescribed routes, traffic laws, site-specific traffic control plans, and environmental permitting requirements; adapt routing and timing to reduce disruption and ensure on-time deliveries.
Coordinate closely with site superintendents, foremen, contractors, and other equipment operators; respond promptly to radio, phone, or dispatch instructions and adjust operations to meet changing site priorities.
Implement spill prevention and containment procedures; immediately report and respond to any spills, leaks, or environmental incidents per company policy and regulatory requirements.
Perform routine preventative maintenance tasks such as topping fluids, greasing fittings, replacing filters, tightening hose clamps, and cleaning tanks; escalate mechanical issues to maintenance teams for repairs.
Secure tanks and loads for travel using straps, valves, manway covers, and other restraints; ensure the tanker meets weight, balance, and placarding rules for safe highway operation.
Load and stage equipment and hoses safely on site, assist with manual hose handling and occasional light rigging; ensure walkways and access points are clear and safe for other personnel.
Conduct spot checks of water quality and temperature where required, document source of water, and follow environmental constraints (e.g., sediment, chemical contamination) before application.
Respond to weather, dust, or traffic-control emergencies by prioritizing critical deliveries, increasing spray frequency during high-wind or dry conditions, and supporting erosion-control efforts after storms.
Train and mentor less experienced drivers and helpers on safe tanker operations, valve and pump use, site protocols, and DOT inspection requirements.
Participate in daily safety briefings (toolbox talks), job hazard analyses (JHAs), and OSHA-required training; promptly correct unsafe acts or conditions and report near-misses and incidents.
Use GPS, mobile apps, and two-way radios to navigate, confirm delivery points, and record completed stops; maintain clear communication with dispatch to support efficient fleet utilization.
Apply anti-freeze procedures, winterize equipment, and perform cold-weather operating techniques such as tank heating or line flushing when operating in freezing climates.
Ensure security of hoses, fittings, and valuable tools when leaving vehicle unattended; maintain cleanliness of truck exterior and cab to project professional company image at client sites.
Follow confined space and hot work procedures when entering or working around tanks, manways, or repair areas; utilize required PPE and permit systems when necessary.
Enforce site access requirements such as permits, traffic control, and personal protective equipment for those loading/unloading water; verify credentials of site personnel as required.

Secondary Functions

Assist with general site housekeeping, barricade placement, and temporary traffic control when not actively operating the truck.
Support light equipment loading/unloading for other site crews and assist in coordinating crane or rigging activities when water truck placement is required.
Provide basic emergency response support, including assisting in first aid until professional help arrives, and helping move personnel or equipment during evacuations.
Participate in continuous improvement initiatives by providing feedback on route efficiency, pump performance, and equipment reliability.
Help maintain fleet records, spare parts inventories, and supplies for daily operations (hoses, gaskets, clamps, PPE).
Cross-train on related fleet vehicles (vacuum trucks, flatbeds, tanker trailers) to increase operational flexibility.
Attend refresher training sessions on environmental compliance, spill response, DOT regulations, and defensive driving as scheduled.
Assist dispatch with updating delivery schedules, logging site-specific restrictions, and confirming access windows with clients.
Support pre-construction site surveys by documenting water access points, potential hazards, and recommended staging locations.
Aid in customer service interactions onsite by answering basic client questions about water delivery and notifying supervisors of any service delays.
