OWTS Professional Registrations Expiring

Registered/Licensed Onsite Wastewater Treatment System (OWTS) Professionals are required to complete continuing education and renew their registration before the end of a three-year registration period.  The list below includes professionals whose registration/license has recently expired.  Note that the list will be updated regularly.  However, for a short time the list might include a professional’s name even after the individual renewed their registration during the brief grace period allowed. You may request that an OWTS professional show identification and/or proof of registration or contact the Onsite Sewage Program to confirm current registration status.
