(A) A water main shall be laid at least ten feet horizontally from any existing or proposed drain or sewer line. However, should local conditions prevail which would prevent a lateral separation of ten feet, a water main may be laid closer than ten feet to, or in the same trench as a storm or sanitary sewer provided the main is laid in a separate trench or on an undisturbed earth shelf located to one side of the sewer and at such an elevation that the bottom of the water main is at least 18 inches above the top of the sewer.
(B) If it is impossible to obtain proper horizontal and vertical separation as stipulated in this section and § 50.096, both the water main and sewer shall be constructed of mechanical-joint, ductile-iron pipe and shall be pressure-tested to assure watertightness before backfilling.
