6×6 Sinotruk Howo 20t off road water tender truck for sale nigeria

Name: 6×6 Sinotruk Howo 20t off road water tender truck for sale nigeria
Brand: Sinotruk HOWO

The 6x6 Sinotruk HOWO 20t off road water tender truck is a 20 cubic metre water carrier built on a heavy duty 10 wheel chassis for use in construction, mining, drought relief, and agricultural irrigation. It is designed for operation on unpaved roads, rough terrain, and remote sites where water supply infrastructure is absent. The truck transports potable water when the tank is treated or made from stainless steel, and can also deliver water for road cleaning, dust suppression, and plant irrigation. It is supplied to contractors, government agencies, and rural water services in regions such as Nigeria with limited access to water networks.

Rear working platform, high cannon, and spray nozzles are mounted on the subframe
Body is shot blasted, primed, and painted in customer specified color
All systems are tested on the factory apron including pump flow, brake response, and electrical function
Photos and videos of the finished truck are sent to the buyer before balance payment

Testing

Quality Control

Vehicle built to GB7965 performance requirements for water tankers
Tank tested for pressure and leaks before final assembly
Every truck undergoes 100 percent testing before delivery
Photos and videos of the finished truck are provided before the balance payment
In-house testing available for pressure vessel projects including non-destructive testing

Build to Order

Customization Options

Tank material can be changed from carbon steel to stainless steel upon request
Tank capacity can be adjusted to meet specific water delivery requirements
Tank color and logo applied free of charge to match customer branding
Left or right hand drive chassis available to match local traffic rules
Spray system configuration can be modified for front, rear, or side water distribution
Pump and piping layout can be adapted to customer equipment and operational needs

Comparison

How It Compares With the Alternatives

4x4 water tanker with 10 m³ tank	Lower cost and better maneuverability in urban areas but cannot carry enough water for remote or large-scale operations
6x4 water tender with 15 m³ tank	Less off road capability and reduced traction on steep or muddy terrain due to fewer driven axles
Water truck with a standard chassis and no rear working platform	Cannot perform targeted watering or road cleaning tasks without additional equipment

Operating Notes

Use Guide

Confirm the drive configuration and hand of drive at order stage to match local road regulations
Fill the tank only through the manhole or pump inlet; keep the air breather valve clear
Use the rear working platform and high cannon only when the truck is parked and stable
Operate the pump at full capacity only when the tank is at least 80 percent full to avoid cavitation
Drain the tank and pump after use in freezing conditions to prevent damage
Free technical training is available at the factory before shipment
