Our Mission Statement

Changing Lives… One At A Time.  Improving Human Life Through Improving Water Treatment…

The goal of the Water Technologies Training Institute is to produce the best trained reverse osmosis and advanced water treatment technicians in the world. Current water treatment training programs and in-house training on location are failing to keep up with the growth of demand. There are few places where in two semesters and with no previous degree requirement individuals can obtain outstanding, high-paying jobs. It’s also hard to imagine many other fields with more job security because the need for clean, pure water will never diminish! It’s only growing and growing fast.

About WTTI

Water Technologies Training Institute (WTTI) was founded in 2008 by David H. Paul, Inc. This unique hybrid online/on-site program prepares students for a career in advanced water treatment.  Since 1988, David H. Paul has been the world’s leader in providing high-tech water treatment training and currently consults with treatment facilities all over the world.

Our History

In the mid-1970s,  David Paul, founder and president of David H. Paul, Inc., was part-time faculty at a branch of New Mexico State University, which became San Juan College, located in Farmington, NM.  He loved teaching but needed a master’s degree to be a full-time instructor.  While completing his master’s in microbiology, David began working at the San Juan Generating Station twenty miles west of Farmington.  His first job was as a “bottom-of-the-ladder” water treatment operator. Over the next six years, that facility designed and constructed one of the most complex high-tech water treatment systems in the world which functioned with zero liquid discharge meaning zero water pollution.

 All water treatment training at the plant had to be created in-house, because no training existed anywhere on the new reverse osmosis water treatment technology.  David recognized this opportunity and formed David H. Paul, Inc. (DHP) dedicated to training existing water treatment personnel on the new membrane water treatment technologies.

It became clear that advanced water treatment was growing rapidly and that water treatment professionals in every industry needed an in-depth training program.

Over a four-year period (1992-1996) DHP created a 4,000 page water treatment correspondence program that taught people already in the industry what they needed to know to understand high-tech water treatment.  The demand for trained professionals was growing tremendously.  In 1998 San Juan College and DHP partnered on presenting the first-ever on-campus industrial water treatment program.  This was a four-semester program from which a graduate could earn an Associate of Applied Science degree in Industrial Water Treatment.

This course of study used DHP’s Water Treatment Certification Program as the curriculum and added to it a hands-on training component with real reverse osmosis units. DHP partnered with three other colleges around the country to offer similar training programs. The rapid changes in water treatment technologies in the early 2000s required a complete overhaul of the on-campus program.  DHP’s new computer-based training was incorporated into the new program, now known as the Reverse Osmosis Technician Program (ROTP).

ROTP was created for the following reasons:

  • College programs could not meet the demand for trained professionals which continues to escalate dramatically
  • Business owners were requesting programs for effectively training their employees
  • Potential students across the U.S. were demanding an online program in reverse osmosis water treatment  that would also offer hands-on training
  • Most companies are looking for professionals trained specifically in water treatment operations and do not require a degree for these jobs
  • The demand for professional water treatment specialist is growing exponential
