Features
ENHANCED SITE SAFETY
BOOSTS SAFETY
- The Cat 789D water truck is equipped with the Command for hauling autonomous haulage solution, which makes it possible for the truck to drive among other staffed and autonomous machines, along haul road routes and within active load and dump areas.
- Enhances safety by removing operators from hazardous or remote sites and reduces the number of people required on site.
- The Cat Water Delivery System utilizes automatic start and stop to help eliminate overwatering at road intersections.
- The system reduces water volume as ground speed is reduced — preventing overwatering at haul road intersections, at the start of grades or when traffic is encountered.
- It minimizes dust, uses less water and prevents underwatering or overwatering — eliminating reduced traction events and allowing water trucks to travel at higher speeds for improved efficiency.
INCREASED PRODUCTIVITY
IMPROVES WATERING OPERATIONS
- Properly watered haul roads directly impact fleet cycle times, enabling you to meet production targets.
- Improves efficiency, enables consistency in operations and provides near-continuous operation through the reduction of operational delays.
- Spend less time maintaining haul roads using proper watering techniques to solve overwatering and underwatering concerns.
- Prevent damage to trucks and reduce unplanned downtime with properly watered haul roads.
- The autonomous water truck coordinates its speed with haul trucks to ensure it does not impede haul traffic and reduce hourly productivity.
CAT WATER DELIVERY SYSTEM
GAIN EFFICENCY WITH A PROVEN WATER DELIVERY SYSTEM
- The Cat Water Delivery System (WDS) is designed to put water to the ground in a controlled, intelligent way.
- This automated system, which is a fully integrated Cat design, controls the amount of water and spray patterns to prevent the hazards common with overwatering. The system improves safety and productivity while saving fuel and conserving water.
- When the truck speed drops below 4.8 kph (3 mph), the system shuts off automatically to prevent overwatering, and then automatically re-starts as speed increases.
- Pump features soft startup and shuts off automatically when the tank is empty, eliminating damage and preventing the pump from running dry.
- Refilling process is completely automated – water truck recognizes when it’s time to refill.
- Maintenance-free and self-cleaning water spray heads reduce truck downtime.
CAT® MINESTAR™ COMMAND
AUTONOMOUS WATER DELIVERY WITH CAT MINESTAR COMMAND
- Cat MineStar Command for hauling creates a fully autonomous water truck that operates safely around other equipment, light vehicles and personnel — all without an operator on board.
- Key to watering operations, MineStar also helps the autonomous truck maintain stability by controlling steering, braking and traction.
- 100% compliance with watering plan and zero incidences of overwatering.
- Water truck reports & tracks amount of water delivered with compliance to site watering plans.
- Provides consistent watering to match production targets.
- Technology connected to our water delivery system increases efficiency to help optimize your water truck fleet size.
SUSTAINABLE OPERATIONS
REDUCES ENVIRONMENTAL IMPACT
- The Cat Water Delivery System provides variable water flow based on truck speed and determines appropriate flow to conserve water.
- Know where, when, and how much to water using technology driven by automation.
- Automated system uses less water and efficiency improvements reduce fuel usage.
TRACK AND REPORT
MONITOR YOUR WATER OPERATIONS
- The Cat autonomous water truck is equipped with Cat MineStar, which collects and communicates real-time information and provides data logging capabilities critical to minimizing safety-related liability.
- MineStar provides information on truck location and utilization data, fuel and water level, whether or not the truck is spraying water, and WDS utilization.
- Optional premium connectivity includes a comprehensive reporting package with data and reports that can help improve watering efficiency.
- Water solutions data can help ensure you're meeting regulatory requirements.
- MineStar doesn't just monitor how much water the trucks have put down. It monitors the actual saturation levels of the haul roads.
- Watering assignments can be amended on request when it's necessary to address watering of specific haul roads or locations. For example, a water truck may be reassigned to a load or dump area to address priority dust suppression needs based on pit personnel requests.
DEALER SUPPORT
BACKED BY THE ONE YOU TRUST
- The Cat Autonomous Water Truck includes the full support of the Cat dealer and parts network.
- The truck and WDS are covered by a Caterpillar warranty, with service parts available for both.
- The truck is eligible for Equipment Protection Plans (EPP) and Customer Value Agreements (CVAs).
- Retrofit kits are available and can be installed by your local dealer.

Features
ENHANCED SITE SAFETY
BOOSTS SAFETY
- The Cat 789D water truck is equipped with the Command for hauling autonomous haulage solution, which makes it possible for the truck to drive among other staffed and autonomous machines, along haul road routes and within active load and dump areas.
- Enhances safety by removing operators from hazardous or remote sites and reduces the number of people required on site.
- The Cat Water Delivery System utilizes automatic start and stop to help eliminate overwatering at road intersections.
- The system reduces water volume as ground speed is reduced — preventing overwatering at haul road intersections, at the start of grades or when traffic is encountered.
- It minimizes dust, uses less water and prevents underwatering or overwatering — eliminating reduced traction events and allowing water trucks to travel at higher speeds for improved efficiency.
INCREASED PRODUCTIVITY
IMPROVES WATERING OPERATIONS
- Properly watered haul roads directly impact fleet cycle times, enabling you to meet production targets.
- Improves efficiency, enables consistency in operations and provides near-continuous operation through the reduction of operational delays.
- Spend less time maintaining haul roads using proper watering techniques to solve overwatering and underwatering concerns.
- Prevent damage to trucks and reduce unplanned downtime with properly watered haul roads.
- The autonomous water truck coordinates its speed with haul trucks to ensure it does not impede haul traffic and reduce hourly productivity.
CAT WATER DELIVERY SYSTEM
GAIN EFFICENCY WITH A PROVEN WATER DELIVERY SYSTEM
- The Cat Water Delivery System (WDS) is designed to put water to the ground in a controlled, intelligent way.
- This automated system, which is a fully integrated Cat design, controls the amount of water and spray patterns to prevent the hazards common with overwatering. The system improves safety and productivity while saving fuel and conserving water.
- When the truck speed drops below 4.8 kph (3 mph), the system shuts off automatically to prevent overwatering, and then automatically re-starts as speed increases.
- Pump features soft startup and shuts off automatically when the tank is empty, eliminating damage and preventing the pump from running dry.
- Refilling process is completely automated – water truck recognizes when it’s time to refill.
- Maintenance-free and self-cleaning water spray heads reduce truck downtime.
CAT® MINESTAR™ COMMAND
AUTONOMOUS WATER DELIVERY WITH CAT MINESTAR COMMAND
- Cat MineStar Command for hauling creates a fully autonomous water truck that operates safely around other equipment, light vehicles and personnel — all without an operator on board.
- Key to watering operations, MineStar also helps the autonomous truck maintain stability by controlling steering, braking and traction.
- 100% compliance with watering plan and zero incidences of overwatering.
- Water truck reports & tracks amount of water delivered with compliance to site watering plans.
- Provides consistent watering to match production targets.
- Technology connected to our water delivery system increases efficiency to help optimize your water truck fleet size.
SUSTAINABLE OPERATIONS
REDUCES ENVIRONMENTAL IMPACT
- The Cat Water Delivery System provides variable water flow based on truck speed and determines appropriate flow to conserve water.
- Know where, when, and how much to water using technology driven by automation.
- Automated system uses less water and efficiency improvements reduce fuel usage.
TRACK AND REPORT
MONITOR YOUR WATER OPERATIONS
- The Cat autonomous water truck is equipped with Cat MineStar, which collects and communicates real-time information and provides data logging capabilities critical to minimizing safety-related liability.
- MineStar provides information on truck location and utilization data, fuel and water level, whether or not the truck is spraying water, and WDS utilization.
- Optional premium connectivity includes a comprehensive reporting package with data and reports that can help improve watering efficiency.
- Water solutions data can help ensure you're meeting regulatory requirements.
- MineStar doesn't just monitor how much water the trucks have put down. It monitors the actual saturation levels of the haul roads.
- Watering assignments can be amended on request when it's necessary to address watering of specific haul roads or locations. For example, a water truck may be reassigned to a load or dump area to address priority dust suppression needs based on pit personnel requests.
DEALER SUPPORT
BACKED BY THE ONE YOU TRUST
- The Cat Autonomous Water Truck includes the full support of the Cat dealer and parts network.
- The truck and WDS are covered by a Caterpillar warranty, with service parts available for both.
- The truck is eligible for Equipment Protection Plans (EPP) and Customer Value Agreements (CVAs).
- Retrofit kits are available and can be installed by your local dealer.
