This section is intended to be in conformance with Cal. Administrative Code, Title 22, Division 4, Chapter 16, § 64572. Water mains and sewers shall not be installed in the same trench and shall be separated as required by the state with sanitary sewers always located lower than water mains.
(A) Parallel construction: the horizontal distance between pressure water mains and sanitary sewers shall be at least ten feet measured from the nearest outside edge of each pipe barrel. The horizontal distance between water service connections and building laterals shall be as specified in the Uniform Plumbing Code.
(B) Perpendicular construction (crossing): the bottom of pressure water mains shall be no less than 45 degrees to and at least one foot above the top of sanitary sewers where these lines must cross.
(C) Special provisions: certain local conditions, including, but not limited to, topography and available space, may create a situation where there is no alternative but to install water mains or sewer lines at less than the required separation. In such cases, rigid construction requirements subject to special provisions must be met. These special provisions will be in accordance with the latest State Board requirements.
