BAT Installer Certification Program


The MOWPA Installation of On-site Wastewater Treatment Systems Certification Program educates and trains practitioners in the use of the best practices for installation of onsite wastewater treatment systems.  The goal of this program is to set industry standards on installation and discuss the various treatment and distribution technologies currently available.  The fundamental message of this training is that through proper installation practices on-site systems are a permanent and effective part of the Maryland’s wastewater infrastructure.  This Course is based on CIDWT’s Nationally recognized Installer Training program and satisfies Maryland Department of the Environment’s requirements and core objectives for installation of BAT systems.  Installers should check with local permitting agencies to determine if you additionally need a local installer’s license or local installer certification.

This 2-day program addresses all general aspects of proper installation procedures of on-site systems and will be instructed by Eddie Harrison of MOWPA and Steven Krieg and Josh Flatley of MDE.  This course is specific to installation only and will not certify you to perform Operation or Maintenance on BAT systems.  Inspectors and Designers of on-site systems are encouraged to also attend this course.  This course will be submitted to theMaryland Board of Environmental Health Specialists (15 CEU’S) The Board of Professional Engineers has also recognized MOWPA as an approved training organization for contact hours.

Attendees receive the following materials:

  • CIDWT’s Comprehensive Installer Manual
  • Helpful and detailed Installation Checklists
  • Study material and example problems
  • MOWPA Certificates will be issued based upon completion of the course and passing the examination and Certification Cards will be issued by MDE
