Municipalities, in consultation within their respective principal authorities, should consider establishing a discretionary on-site sewage system (i.e. septic system and holding tank) maintenance inspection program under the Ontario Building Code, and extending the education and awareness program specified in 6.2.1- CW to the balance of the Wellhead Protection Areas where on-site sewage systems are moderate or low drinking water threats.

The principal authority for Part 8 of the Ontario Building Code for each of the municipalities should also provide notice of whether or not a discretionary sewage system (i.e. septic system and holding tank) maintenance inspection program(s) will be established, including the applicable areas and a rationale for the decision, by February 15 of the year following implementation.
