Non-sewered commercial plumbing applications

This information is designed to assist you with the preparation of the required documentation for a plumbing application for a non-sewered commercial site, so that it may be assessed in a timely manner.

Please note, applications missing information may experience processing delays.

The timeframe for a plumbing application on a non-sewered commercial site is 10 business days for preliminary assessment.

A site inspection is required as part of the assessment of the application. If access to the property cannot be gained due to a locked gate or dogs, please advise us when lodging the application so that a time can be booked for the inspection.

Alterations or additions to existing structures
