For manholes five (5) feet in diameter, add an additional fifteen (15) seconds and for
manholes six (6) feet in diameter, add on additional thirty (30) seconds to the time
requirements for four (4) foot diameter manholes. For all manholes deeper than
twenty -five (25) feet, the Engineer will determine the applicable minimum elapsed
time.
D. If the manhole fails the test, necessary repairs must be made and the vacuum test and
repairs must be repeated until the manhole passes the test.

inspection, an additional fee of $75.00 will be due. This must be paid prior to the
time of the follow up inspection.
5. Property owners are herby advised that the County Board of Health regulates the
operation and maintenance of pri vote sewage disposal (septic) systems. The
County Ordinance provides in part that, upon connection to a public sewer, a
septic tank shall be abandoned and filled with earthen material in a safe and
sanitary manner. Please contact the appropriate Count y Board of Health for
further information.
