Event Description

The Intermediate and Advanced School offers courses that are designed to furnish established operators with information needed to better understand treatment processes and to perform their duties in an ever-changing environment. The courses offered at this school include:

  • Intermediate Water
  • Advanced Water
  • Intermediate/Advanced Wastewater 
  • Activated Sludge 
  • Industrial Wastewater

These courses provide opportunities to prepare for the certification exams. However, the courses should not be used as the only study guide for the exams. The conference is NOT affiliated with the Colorado Operator Certification Program Office. The school registration does not include the exam.

RMWEA also offers an annual Fundamentals School focusing on the basics of water and wastewater treatment for new operators. 

Additional Information

Scholarship options are available. Submit the Scholarship Application by April 2nd, 2023. Scholarships covering the tuition for one course of study in the Intermediate/Advanced School will be awarded to applicants employed by a town or municipality water or sewer district serving fewer than 3,300 residents within the Rocky Mountain Region. (CO, NM, WY). Scholarships will be reviewed and awarded based on the size of the community served, location, and level of certification required for that entity by the scholarship review board.

 Water Security and Emergency Response Planning

Advanced Water
This course provides information on new topics facing the water field. The course is not geared toward the operator’s certification testing for certification. The course is geared toward operators with multiple years of experience in the field.

Course Topics:

 Unit Process Optimization

 Emerging Contaminants

 Taste and Odor


 Security/Vulnerability Assessment


 Plant Tours

 Granular Media Filter Operation

 Biological Filter Operation

 GAC Adsorption

 Advanced Oxidation    


 Sanitary Survey and Inspections

 Reservoir Management/Microbiology


 Management/Project Management

Industrial Wastewater
This course trains operators in the safe and effective operation of industrial wastewater treatment plants, with a focus on physical-chemical processes. Emphasis is given to facilities that neutralize acidic and basic water and that remove metals from wastewater.

Course Topics:

 Neutralization/Metals Precipitation

 Air Stripping


 Carbon Adsorption/Ion Exchange

 Clarification Sludge Processes

UV Oxidation

 Math for the Process Operator

 Wastewater Microbiology
