SEC. 6-403. - PERMITS REQUIRED.

No well shall be drilled within the City of Fresno by any person without first securing a permit therefor from the Director of Public Works. Before the drilling of any well is begun, the person desiring to drill such well shall pay to the Department of Public Works the amount designated in the Master Fee Resolution, and file a verified statement setting forth the location of the well, the purpose for which the water from such well will be used, and a detailed sketch of the proposed installation. The Director of Public Works shall thereupon investigate the proposed drilling of said well to determine whether the proposed drilling will pollute or imperil the public water supply of the city, and will conform to the requirements of this Code. If the Director of Public Works finds that the drilling of said well as proposed will not pollute or imperil the water supply of the city, and that the location of the proposed well meets the requirements set forth in Section 6-407, he shall issue a permit to drill the well, but otherwise he shall withhold the permit. The fee so paid shall cover the cost of such investigation, and shall not be returned to the applicant whether the permit is granted or refused. Where application for permit is made at the same time for two wells, one a supply well and one a drainage well, both of which are to be located on the same premises, the fee provided herein shall cover both wells. The permit fee is waived for governmental agencies including the county, school districts, and other special districts. (Orig. Ord. 4187; Am. Ord. 5805, 1960; Am. Ord. 6436, 1964; Am.
