Septic Permit

​On-Site Sewage Systems are regulated by the Municipality of Chatham-Kent under the Ontario Building Code Act. The Municipality issues permits and inspects all sewage systems with a daily design flow of less than 10,000 litres per day.


Septic Permit Requirements

A septic permit is required for new construction, existing system tank replacement and when lines are added or lengthened.

It is a requirement that on-site sewage systems be designed and installed by licensed professionals qualified by the Ministry of Municipal Housing & Affairs. You may install and repair your own septic system, though you will still require a permit and inspection from the Building Department. 

Submit your completed worksheet, your signed and completed application and your site plan (details below), to ckbes@chatham-kent.ca. Please note, the largest we are able to print is 11" x 17" paper size. Larger drawings will need to be dropped off at Chatham Civic Centre or mailed.
