After completion of the sewer, the City may require an infiltration or exfiltration test, whichever is decided by the City Engineer to be most practical at the time of completion. The infiltration shall not exceed 500 gallons of water per inch of pipe diameter per mile of sewer in a twenty-four hour period. Exfiltration shall not exceed 500 gallons of water per inch of diameter of pipe per mile of sewer in a twenty-four hour period based on a two foot minimum head. The maximum infiltration and/or exfiltration may be lowered by a note on the plans, special permit or in the general specifications of the City. This test shall be made by the contractor at his expense under the supervision of the City Engineer.
