Name: Sinotruk Howo 3000gallons sewage truck for sale Thailand
Brand: Sinotruk HOWO

The Sinotruk HOWO 3000 gallon sewage truck is a 3000 litre vacuum suction vehicle built on a 6x4 HOWO chassis with a 266 HP diesel engine and 10 forward, 2 reverse gearbox. It is designed for municipal sanitation departments and waste contractors that need to collect sludge, mud, and debris from manholes, water wells, and sediment traps in urban and rural areas without access to centralized pumping infrastructure. The truck uses a dual-stage vacuum pump system to fill the tank in under 10 minutes and features a 9 metre swivel suction tube with a 360 degree rotating head for access to tight or obstructed entry points.

Key Benefits

3000 litre carbon steel or stainless steel tank holds a full load of sludge and prevents overflow with a 6 inch disc valve outlet
Hangzhou Weilong 68/7000 double vacuum pump system achieves full tank fill in 10 minutes
9 metre 360 degree swivel suction tube with anti-overflow valve accesses manholes in confined spaces
Left hand drive chassis and 55 degree hydraulic cab tilt allow safe operation in narrow streets and tight sites
Dual circuit compressed air brakes and engine exhaust brake improve control on uneven terrain and steep grades
Tank with four internal baffles and turtle head design reduces liquid surge during transport and braking

Buyer Profile

Who It Is for

Comparison

How It Compares With the Alternatives

3000 L vacuum truck with single pump	Slower fill time and less reliable under continuous use, but lower initial cost
10,000 L sewage truck with 8x4 chassis	Higher capacity and better off-road performance but harder to maneuver in narrow urban streets
Used sewage truck from Europe	Lower upfront cost but limited spare parts and no local technical support after 5 years

Operating Notes

Use Guide

Confirm left or right hand drive chassis at order stage to match local traffic rules
Fill the tank only through the manhole or suction inlet and keep the air breather valve clear
Do not exceed 10 minutes suction time per cycle to avoid pump overheating
Engage the engine exhaust brake when descending slopes to reduce brake wear
Drain the tank and flush the suction tube after each use to prevent clogging
Free technical training is available at the factory before shipment
