A. Sewer Force Mains: Sanitary sewer force mains are not permitted to be constructed over water mains. Force mains constructed parallel to water mains must have the required separation as given in Section 8-1-22 regardless of construction. When sanitary sewer force mains must cross under water mains, special approval of the County Health Department is required in advance. (Ord. 487 N. S., 4-1-1991; 1996 Code)
B. Sewer Main Crossing Water Main: Where a sanitary sewer main must cross over a water main, it should cross at a ninety degree (90o) angle, if possible, and the length of sewer pipe shall be centered on the water pipe so the sewer joints are the maximum distance from the water pipe.
C. Pressure Testing: In pressure testing new water mains and/or sanitary sewer mains, special attention should be given to those areas where the lines are in close proximity. (Ord. 487 N.S., 4-1-1991)
D. Special Circumstances; County Review: The basic separation requirements given are for the normal conditions found with sewage collection lines and water distribution mains. More stringent requirements may be necessary for special circumstances such as water mains buried deeper than normal, unstable soil conditions, high ground water, etc. These situations must be reviewed with the County Health Department and the Public Works Director in advance.
