Watermaster Amphibious Multipurpose Dredger excels alone in the tasks that are conventionally handled with multiple separate machines. With its versatile selection of quickly changeable attachments, the Watermaster can do all shallow water work from dry ground up to the depth of six meters.

Watermaster’s own state of the art Dredging Cutter Pump is an essential part of the Watermaster concept. Together with the Integrated Watermaster Operating System (IWOS) It enables 50 % to 100 % more effective pumping time compared to traditional machinery. Submersible pump allows working in very shallow waters or even from the dry land. It includes two cutter crowns for different kinds of soils and an integrated vegetation cutting knife system. The maximum pumping distance is 1,5 km. Watermaster is fully amphibious also when operating with the Dredging Cutter Pump.
Large Work Area Maximizes Productivity (IWOS)
Steady independent anchoring with four stabilizers. The most efficient backhoe dredging depth is 0–4,5 meters. Several attachments available: 600 liter bucket with teeth, 700 liter bucket without teeth, clamshell bucket.
600 L Bucket
700 L Bucket Without Teeth
Watermaster's rake attachment is a 2,75-meter wide tool for removing trash and vegetation – both floating and rooted.
Two attachments are available for piling work; the Piling bucket for wooden piles and the vibratory piling tool for both metal sheets and wooden piles. Watermaster grabs the piles from the side and can thus handle longer piles.
Shallow water work has traditionally been divided between excavators and conventional cutter suction dredgers. Excavators have been used for the more shallow and narrow parts and conventional dredgers for deeper and wider areas.The Watermaster Amphibious Multipurpose Dredger single-handedly covers all shallow water work from dry ground up to the depth of 6 meters. Watermaster is specifically designed and certified for both water work and for working from the land side.Suction dredging, excavating, raking and pile-driving - all applications cost-effectively with one versatile machine.Do more with less by using multipurpose Watermaster technology.
WATERMASTER COVERS THE WHOLE SHALLOW WATER AREA FROM 0 TO 6 METERS DEPTH
Watermaster can independently move, anchor and work in the whole shallow water area from dry ground to 6 meters depth. Traditionally same work area requires many machines and assisting units.
WATERMASTER IS A MULTIPURPOSE DREDGER
Watermaster excels in suction dredging, excavating, pile-driving and raking. Watermaster’s work efficiency and anchoring stability is in a class of its own thanks to the smart Watermaster operating system (IWOS).
WATERMASTER IS FULLY AMPHIBIOUS
Watermaster is a fully amphibious vessel that does not only float, but truly masters the water. It is self-propelled and can travel considerable distances in water to reach the work site (max. speed 4 knots). On dry ground Watermaster has the ability to walk. Watermaster is stable, safe and tested.
WATERMASTER IS SPECIFICALLY DESIGNED AND CERTIFIED FOR SHALLOW WATER WORK
Watermaster is fully capable and certified for working safely both in water and from land side. The design is approved by Bureau Veritas. Each Watermaster is inspected by a maritime authority.
The truly amphibious Classic V offers an unseen combination of mobility and heavy duty dredging capacity. New Aquamec innovations take Watermaster to a new performance level in soft soil, hard soil and urban dredging. After years of research, development and thorough testing, the Watermaster Classic V is now ready.
+50 % Dredging Capacity. Same Size
Classic V completes projects faster
It would be easy to increase dredging capacity by growing the size and weight of the dredger, but at the same time you would lose the excellent mobility, which is the key feature of an amphibious multipurpose dredger.
The challenge has been to increase dredging capacity while keeping the dredger compact, mobile and robust at the same time. Watermaster Classic V combines power and functionality in a unique way.
The size of Watermaster has stayed basically the same (20 tons) since the first generation Classic I, but the dredging capacity has nearly tripled. The difference compared to Classic IV is +50 %.
Urban Dredging Concept
Slice and pump the soil containing trash
- The innovative Watermaster Urban Dredging Concept, includes patented technology.
- Enables suction dredging at debris-filled urban sites where only excavation work was previously possible.
Hard Soil Dredging Concept
Loosen and pump the hard soil
- New cutter crown for hard soil. New, more powerful hydraulic motor for more cutting force.
- Watermaster has reached a new capacity level in hard soil dredging.
