Sinotruk Howo 18tons water sprinkler truck Dominican Republic

Name: Sinotruk Howo 18tons water sprinkler truck Dominican Republic
Brand: Sinotruk HOWO

The Sinotruk HOWO 18-ton water sprinkler truck is a 6x4 water transport vehicle built on a 10-wheel chassis with a 336 HP diesel engine and 10-speed manual gearbox. It is designed for municipal water supply, road cleaning, agricultural irrigation, drought relief, and landscape maintenance in regions with limited water infrastructure. The truck carries up to 18,000 litres of water and can deliver it through front, rear, and side sprayers, or via a high-pressure rear cannon for tree and vegetation watering. It is suitable for use in construction zones, rural areas, and urban environments where consistent water delivery is required without reliance on fixed hydrants.

Comparison

How It Compares With the Alternatives

4x2 water tanker with 10,000 L tank	Lower load capacity and less stability on rough terrain but easier to maneuver in tight urban spaces
Water truck with only rear spray	Limited cleaning coverage but simpler maintenance and lower cost
Water truck with no high cannon	Cannot reach tall trees or elevated vegetation but sufficient for road and surface cleaning

Operating Notes

Use Guide

Fill the tank only through the manhole or pump inlet to prevent contamination
Use the high cannon only when the truck is on level ground and the stabilizer legs are deployed
Clean spray nozzles and pump filters after each use to prevent clogging
Drain the tank and pump after use in freezing conditions to prevent damage
Free operator training is available at the factory before shipment
