Should persons or property be threatened by a sudden, unforeseen impairment in the quantity or quality of water available, so that it becomes necessary to obtain a new water supply or increase the existing supply and a permit cannot be obtained because city offices are not open, a well may be constructed, deepened or reconstructed without a permit. All work done under such emergency conditions shall comply with the requirements of this chapter. In all such cases, the person who caused the work to be done shall, within forty-eight (48) hours after such work is begun, excluding weekends and holidays, file a statement with the health officer indicating the reason for the emergency work. The health officer shall inspect the well and order the person who caused the emergency work to be done to perform such other and further work, if any, as shall be necessary to bring this well into conformity with the requirements of this chapter. The terms of such an order shall be deemed permit conditions within the meaning of Section 13.16.140. (Prior code § 7767)
