The CPOW OWTS Design Course is a completely updated course that was developed in response to the growing needs for a Colorado-specific, comprehensive, design course. The course is a hybrid of online modules, created by both CPOW and NOWRA, followed by a two-day, in-person classroom instruction with a field component. *The online modules are to be completed prior to attending the in-person portion.* The course presents science based principles of design, while including practical applications using the Colorado Department of Public Health and Environment Regulation 43 On-site Wastewater Treatment Systems requirements. In addition to being a useful course for Designers, other industry professionals, such as Regulators, Installers, and Service Providers can benefit from the course. There will be an exam at the completion of the course. A passing score is required to receive a CPOW completion certificate.

THIS COURSE IS BEING HELD BOTH IN-PERSON AND ONLINE THROUGH ZOOM.
*For those attending Online, a webcam is required for taking the Online Exam at the end of the 2-day course for Certification.*

The NAWT OWTS Inspection Standards class is a nationally recognized Onsite Wastewater Treatment System (OWTS) class developed to provide training, education, testing and certification for individuals conducting OWTS inspections for property transfers, system functionality and county or homeowner association requirements. The course covers the newly adopted NAWT OWTS Inspection Standards and helps guide the inspector through the inspection steps with the goal of arriving at a conclusion for each component and an overall conclusion for the system. The NAWT level of inspection is the Operations Level. All parts and components are assessed, and their condition and deficiencies are identified. This is the generally accepted course that state and county health departments use for their certification requirements for individuals operating as OWTS Inspectors.
*Starting in January 2026, all NAWT Inspector Certificate holders will be required to re-take the 2-day Course and Exam for Certification, to cover the new materials and standards. Individuals that received their initial Certification or renewed their existing Certificate in 2025 will have until January 2028 to complete the new course materials and re-take the exam for Certification*

Friday, October 16th – The Installer 2 session is a continuation from Installer 1 with more advanced subject matter for the OWTS Installer. Beginning with an overview of site and soils analysis to help understand the complexity of the soil treatment area as an OWTS component, the course material will look deeper into the techniques and materials necessary for OWTS Installation. The course will also take a broader look at dosing and aerobic systems, their components, and how to ensure proper installation and dosing of these types of systems. In addition, sections will cover the complex components and installation techniques for drip irrigation systems. Completion of the course will provide participants with the knowledge of what is involved be a professional and competent OWTS installer.
