Solids Removal

A new product range will be replacing our standard Jetting, Suction and Air Lift Dredge. More details will be released shortly.

Jetting Dredge

The Jetting Dredge (previously the SlurryRat) removed semi-compacted mineral slurries. May be deployed in hazardous environments.

Suction Dredge

Built for soft sludge wastewater plants, the Suction Dredge (previously the SludgeRat) allows for effective and efficient removal of non-compacted / soft organic sludges.

Maintaining water quality means highly efficient operating conditions. Thus, having a reliable and clean water source will result in lower running costs and prevent negative environmental incidents. From slimes management to mineral recovery and process water management, we have worked with it all. 


Heavy Industry

Preventing contamination and the escape of toxic effluents from mineral processing and refineries, into our waterways and oceans is undoubtedly crucial.  We have worked on many projects, in particular, final process ponds managing byproduct concentrates prior to ocean outfall and discharge points.


Municipal Wastewater

Correctly treating and managing our sewage systems can be a complex process but the final outcome is always the same. Above all we need to kill harmful bacteria and viruses, but we can also recover valuable nutrients and water in the process. UAT has successfully completed hundreds of sludge management projects in this market.


water and Sediment

In order to enable safe and stable operations under a range of conditions, keeping your site contaminant free should be a top priority. With expertise in pit and tailings management in both water and sediments, we can solve any problem.

Uncontaminated water is an essential factor in both crop and livestock production, in addition to fostering better performance and growth. Common applications for UAT products have been in the sectors of BioDiesel production, Abattoirs, Feedlots, Wineries and Piggeries.


Resource Recovery

The importance of resource recovery should not be understated. From recycling to recovering valuable minerals, this process often returns far more than the cost of implementation. Platinum, gold, copper, zinc and lead recovery are just a few materials we have recovered.

Power generation

Management of cooling water and separation of flyash and fine sediments through the production of electricity from coal fired power stations is a continuous challenge. We have provided solutions to both power stations as well as cooling tower owners and operators.


Oil & Gas

Contaminated water is a natural byproduct of oil & gas. In general, managing heavy brines during drilling and extraction of gas or settling ponds at an oil refinery demand extremely high levels of compliance and safety. Our products have been successfully supplied and utilized in these industries.



Additionally, we have supplied oxygenation and sludge recovery systems into the pond based aquaculture market. We can supply cost effective solutions to help you achieve better pond health, better production and improve your effluent discharge.

What our clients say

Our Council has been using the assistance of UAT and the Sludge Rat machine to help resolve our settled sludge removal needs in ponds and lagoons on various occasions over past years. It has proven to be a cost effective and efficient way of shifting or removing sludge. I would certainly recommend anyone with sludge problems to contact and trial what UAT has to offer as a very worthwhile exercise. They have shown us very good customer service and I hope UAT prosper into the future.

Ray Collins

Water & Sewer Coordinator, Byron Council

The SlurryRat proved a great piece of technology which solved a critical problem for sediment management at our Kwinana refinery. I would highly recommend it to others.

Rick Benjamin

General Manager, Tronox

Over the past 3 years, the UAT SludgeRats® have provided an excellent solution to the Water Corporation of WA in providing a very competitive & cost effective solution to the desludging of remote wastewater sludge lagoons and ponds. Whilst there are exceptions, the SludgeRat is the Water Corporations preferred technology and method to remove sludge online from large numbers of ponds scattered across our area of operations throughout the state of Western Australia.
