(A) Neither the township nor any other person shall connect any public sewer or system of public sewers to any county sewer, or to any township sewer which is connected directly or indirectly to any county sewer without first obtaining a permit therefor from the county and no other person, other than the township shall connect any public sewer or system of public sewers to any county sewer or to any township sewer without first obtaining written approval therefor from the township. Each connection permit shall show the location and extent of the work, information regarding the owner, the contractor, and the engineer, and any other pertinent information as shall be determined to be necessary. The county permit shall be obtained from the office of the County Agency at G-4610 Beecher Road, Flint, Michigan, from which a fee will be charged by the county except where the connection is made to verify the results of an infiltration test.
(B) A test for water infiltration and air pressure testing of the public sewer or system of public sewers shall be performed by the owner or contractor, after completion thereof, in accordance with the procedures established by the County Agency. When the party has determined that the sewer or system meets the following requirements for maximum infiltration and air pressure testing, then he or she shall arrange for the results of the tests to be verified by the County Agency. Ground water infiltration at any time shall not exceed 250 U.S. gallons per inch of pipe diameter per mile of sewer per 24-hour period. Air pressure testing limits shall be as found in County Standard Specifications. It shall be the responsibility of the township or other party constructing the sewer or sewer system to make whatever corrections may be necessary to the same to meet the infiltration requirements prior to using the county sewers or the township sewers to which connection is made. If, in the opinion of the County Agency, ground water conditions at the time of the test would not provide a conclusive test of the extent of infiltration, then an exfiltration test shall be required. If an exfiltration test is determined to be necessary, the maximum exfiltration rate shall be the same as that permitted for infiltration.
