The Ontario Onsite Wastewater Association (OOWA) is a provincial not-for-profit organization dedicated to promoting the value of onsite and decentralized wastewater management through education, improved standards of practice, and advocacy for sound policies.

Use OOWA’s Registered Professional Program directory to find local septic system installers, designers, haulers, and other professionals. Members participating in the RPP have committed to earning a special designation that requires ongoing education and skills training specific to the onsite wastewater industry.

Hiring a qualified and registered septic professional is essential to the successful installation of your system. Always ask for your professional’s Building Code Identification Number (BCIN) to verify their credentials.

When requesting quotes or estimates, make sure they are detailed and transparent. Ask for specifics such as the materials and soils to be used, and whether services like electrical work are included.
