Mission Statement

The WaterJet Technology Association (WJTA) was created in 1983 at the 2nd U.S. Water Jet Conference, held on the campus of the University of Missouri-Rolla (now called the Missouri University of Science and Technology), by members of the waterjet industry acting in concert with university and government officials. The major impetus to the creation of the Association was to provide a means of service and communication within the industry, as epitomized by the biennial waterjet conferences.

Formal objectives of the Association have been adopted as follows:

  1. To provide a means of cooperation between government, industry, university, and research institutions on all matters of fluid jets and industrial vacuuming, including applications in jet cutting, industrial cleaning, and other uses in the manufacturing, mining, construction, and process industries.
  2. To foster domestic and international trade of products and services relating to waterjet cutting, waterjet cleaning, and industrial vacuuming.
  3. To promote in general the interests of the waterjet application and industrial cleaning industries, including the establishment of recommended practices.
  4. To promote the mutual improvement of its members and the study and advancement of the arts and sciences connected with waterjet cutting and industrial cleaning.
  5. To further these stated purposes, the WaterJet Technology Association may promote and conduct demonstrations for the general public or private organizations; disseminate information on fluid jet technology through newsletters, booklets, clinics, meetings, lectures and educational programs; make awards; and engage in any other activities not enumerated herein that are designed to further the art and science of fluid jet technology and to promote its use.

In regard to the third objective, it should be noted that:

  1. At the 3rd U.S. Water Jet Conference held on the campus of the University of Pittsburgh in May of 1985, the Association adopted the first Recommended Practices for the Use of Manually Operated High Pressure Water Jetting Equipment.  The waterjet Recommended Practices are reviewed and updated periodically.  The last revision and update was done in 2013. In 2011, the manual was retitled Recommended Practices for the Use of High Pressure Waterjetting Equipment.
  2. Recognizing that many industrial cleaning contractors combine high-volume air-moving with waterjetting, the WJTA in August 2007, adopted the first Recommended Practices for the Use of Industrial Vacuum Equipment.  The Recommended Practices for the Use of Industrial Vacuum Equipment are reviewed and updated periodically. The last revision and update was done in 2013.

The WaterJet Technology Association (WJTA) was formed in 1983 at the Second U.S. Waterjet Conference in Rolla, Missouri, when the WJTA founders saw a need for an association to serve the rapidly evolving technology of high and ultra high pressure waterjetting in its many applications.

The WJTA founders set a number of goals: to promote safety, to provide a means of industry communications, to foster trade, and to keep members up-to-date on the ever evolving art and science of high pressure waterjet technology. For thirty years WJTA has provided a forum for the leaders and innovators in the industry to pursue these goals and has grown into a world-class trade association.

The Industrial & Municipal Cleaning Association was added in 2009 to provide a forum for WJTA members with an active interest in high pressure cleaning and industrial vacuuming technology. The addition of the IMCA expanded the scope of the WJTA to include technologies used in conjunction with waterjets in industrial and municipal applications.

After hosting biennial WJTA Conferences since its formation, WJTA-IMCA hosted the first Expo in 2010 drawing parties from the US and abroad to Houston for the only dedicated high pressure waterjet tradeshow in the world.

Throughout its history, WJTA-IMCA has continued to push for safe working practices in the industry. Recommended Practices manuals have been published for operating waterjetting equipment (since 1985) and industrial vacuum equipment (since 2007) and are constantly being updated with new information and guidelines.

WJTA-IMCA is the leading trade association for the waterjet and industrial/municipal cleaning industries in North America, and has members around the world.

Industry sectors served by WJTA-IMCA include, but are not limited to:

  • Waterjet cutting and manufacturing technologies
  • Waterjet cleaning and field services (waterblasting and hydroblasting)
  • Waterjet coatings removal and surface preparation
  • Waterjet concrete removal/hydrodemolition
  • Industrial and municipal vacuuming
  • Industrial cleaning and maintenance
  • Hydro-Excavation, Vacuum Excavation, Tunneling, and Mining
  • And other fluid-jet technologies and applications (including drilling, rock cutting, demilitarization, and more)

Enhance Safety

WJTA-IMCA is dedicated to promoting safety in the industry by publishing safe operating guidelines, distributing safety information, fostering communications in the industry, hosting conferences and seminars, and more.

Facilitate Communication

WJTA-IMCA’s Conference and Expo are essential forums for sharing and developing ideas to further waterjet technology. Additionally, members have access to a directory of contacts in the industry and the WJTA-IMCA Jet News and website are essential sources of news and updates. 

Foster Trade

Although based in North America, WJTA-IMCA has active members around the world who develop, manufacture, sell, and use waterjetting equipment. Through events, communications, and networking WJTA-IMCA is a vehicle for fostering domestic and international trade.

Promote the WaterJet Industry

As one of the most versatile technologies around, high pressure waterjetting remains underutilized in some key applications. WJTA-IMCA works to promote the safe use of waterjet technology in all its applications.

Primary activities of WJTA-IMCA include:

  • Development of safety guidelines and reference materials
  • Organizing the WJTA-IMCA Expo, a tradeshow for the high pressure cleaning industry
  • Hosting the WJTA-IMCA Conference, with cutting edge research papers from innovators in academia and industry
  • Advocating the safe use of high pressure waterjetting technology
  • Distributing information on new developments in the waterjet industry
  • And more
