A private sewage disposal system shall not be made operable until the installation is completed and approved by the Plumbing Inspector. He shall be allowed to inspect the work at any state of construction, and, in any event, the owner shall notify the Plumbing Inspector when the work is ready for final inspection and before any underground portions are covered. The inspection shall be made within 48 hours of the receipt of notice by the Plumbing Inspector.
At such time as a public sewer becomes available to a property served by a private sewage disposal system as provided in § 165-4, a direct connection shall be made to the public sewer in compliance with this chapter, and any septic tanks, cesspools and similar private sewage disposal facilities shall be abandoned, drained and filled with suitable material.
