SINOTRUK HOWO 12000L jet vac combo truck Mauritania

Name: SINOTRUK HOWO 12000L jet vac combo truck Mauritania
Brand: Sinotruk HOWO

The Sinotruk HOWO 12000L jet vac combo truck is a 25000 kg gross weight vehicle built on a 4x4 or 6x4 chassis for municipal sewer maintenance and drainage operations in regions with limited infrastructure. It combines high-pressure jetting and vacuum suction to clear blockages in underground pipelines, lift sludge from manholes, and transport waste to treatment sites. Designed for use in arid and dusty environments like Mauritania, it operates on unpaved roads and in remote locations where access to water and power is limited. The unit is equipped with a 6000L sludge tank and 4000L fresh water tank, allowing for extended field operations without refilling.

Buyer Profile

Who It Is for

Municipal sanitation departments in developing countries with aging sewer networks
National and city water and drainage authorities responsible for public health infrastructure
Contractors hired to maintain or rehabilitate sewer systems under government tenders
Private waste management companies operating in regions with low infrastructure density
Engineering firms managing large-scale urban drainage projects in remote or arid zones
International aid organizations procuring durable, low-maintenance sewer equipment for field deployment

Operating Problems

Problems It Solves

Blockages in old or collapsed sewer lines that cannot be cleared by standard jetting alone
Lack of water supply at remote job sites requiring a built-in fresh water tank for jetting
Manual labor required to empty sludge from manholes due to lack of vacuum capability
Frequent breakdowns from poor component integration in low-cost combo trucks
Short lifespan of pumps and seals due to inadequate pressure relief and material selection
Long lead times and delayed spare parts availability for imported sewer maintenance vehicles

Where It Works

Application Scenarios

Municipal sewer maintenance teams in sub-Saharan Africa operating on unpaved roads and remote access routes
Water and sanitation departments in arid regions where water supply for jetting is limited
Contractors performing emergency blockage clearance in aging urban sewer systems
Remote industrial sites with no access to municipal drainage or treatment facilities
Emergency response teams clearing blocked storm drains after heavy rainfall or flooding
Public works departments managing large-scale sewer rehabilitation projects with minimal downtime

Engineering

Technical Features

Build Materials

Materials

Mild steel tank shell with 5 mm thickness for durability and resistance to abrasion
Stainless steel float ball for primary shut-off valve to prevent corrosion
Aluminium alloy fittings and piping for reduced weight and improved corrosion resistance
Rubber seals and gaskets on valves and lids for watertight and airtight performance
High-strength steel frame and mounting brackets for chassis integration and load distribution

How It Is Built

Manufacturing Process

Chassis is received from Dongfeng, Sinotruk, or Isuzu and wheelbase verified against tank layout
Tank shell is cut, rolled, and welded with internal clapboards to reduce surge during transport
Sludge and water tanks are pressure tested and leak tested before final assembly
High-pressure pump, vacuum pump, and PTO are installed and aligned with the driveline
Hoses, nozzles, valves, and sight glasses are fitted and tested for correct operation
Hydraulic systems for rear lid and tipping cylinder are installed and calibrated
Body is primed and painted in customer colour with logo applied free of charge
All systems are tested on-site: jetting, suction, vacuum, and dumping functions verified

Testing

Quality Control

Every truck undergoes 100 percent testing before delivery
Pressure and leak tests conducted on both sludge and water tanks
High-pressure and vacuum systems tested under full load conditions
Photos and videos of the finished truck sent to buyer before balance payment
In-house testing for pressure vessel components including over pressure relief and safety valves

Build to Order

Comparison

How It Compares With the Alternatives

Standard vacuum truck with no jetting capability	Cannot clear blockages in hard-packed or collapsed pipes, requires manual intervention
Basic jetting truck without vacuum system	Cannot remove sludge or debris after cleaning, requires separate transport for waste
Used imported combo truck	Higher risk of breakdown, limited spare parts availability, longer repair times

Operating Notes

Use Guide

Confirm chassis type and drive configuration at order stage to match local road and registration rules
Fill fresh water tank only through the designated inlet to avoid contamination
Use the SS float ball to prevent overfilling the sludge tank during suction operations
Engage the sandwich PTO before starting jetting or vacuum functions to avoid driveline damage
Inspect hoses and nozzles before each use for wear or blockages
Drain both tanks and flush the system after use in freezing conditions to prevent damage
