Sec. 9.

(a) Water mains shall not be located within ten (10) feet measured horizontally from the outside edge of the water main to the outside edge of any existing and proposed sanitary sewers or storm sewers (sewers), unless the water main and the sewers comply with the following:

(1) The water main and sewers must cross with the water main and sewers separated by a minimum of eighteen (18) inches measured vertically from the outside edge of the water main to the outside edge of the sewers.

(2) The crossing specified in subdivision (1) must be at a minimum angle of forty-five (45) degrees measured from the center lines of the water main and sewers.

(3) The conditions specified in subdivisions (1) and (2) must be maintained for a minimum distance of ten (10) feet from either side of the water main as measured from the outside edge of the water main to the outside edge of the sewers. All sewer pipe joints within this ten (10) feet distance must be compression type joints.

(4) All sewer pipe must be marked to identify it as a sewer pipe wherever a point of crossing with a water main pipe occurs.

(b) A shorter separation distance than that specified in subsection (a) is allowed if the following is conducted within the separation distances specified in subsection (a):

(1) The sewers are joined with compression type joints and meet all water main requirements as described in sections 8 and 17(a) of this rule.

(2) The water main and sewers are not in contact.

(c) Water mains shall be separated from existing and proposed aboveground or underground storage tanks and their distribution devices containing or potentially containing hazardous materials, petroleum products, or waste materials by a distance of twenty-five (25) feet horizontally measured from the outside edge of the water main to the outside edge of the tank or distribution device and shall not cross such tanks or distribution devices.

(d) Water mains shall be separated from the following existing and proposed potential sources of contamination or damage (sources) by ten (10) feet measured horizontally from the outside edge of the water main to the outside edge of the source and shall not cross such potential sources:

(1) Aboveground and underground storage tanks containing materials other than those under subsection (b) or potable water.

(2) Sewage or septic treatment equipment and septic tank absorption field trenches, lift stations, and grave sites.

(e) No water main shall be within eight (8) feet of a sanitary sewer manhole, a storm sewer manhole, or a drainage grate support structure as measured from the outside edge of the water main to the outside edge of the sanitary sewer manhole, storm sewer manhole, or drainage grate support structure.

(f) Water mains shall be separated from existing or proposed landfills by fifty (50) feet measured horizontally from the edge of the water main to the outside edge of the waste boundary of an existing or proposed landfill. In addition, water mains within three hundred (300) linear feet of the outside edge of a waste boundary of an existing or proposed landfill shall be constructed of nonpermeable materials. Water mains shall not cross or pass through the waste boundary of an existing or proposed landfill.
