practical to maintain a ten-foot separation, the Water Superintendent,
Town Engineer or other duly authorized officials of the Town may allow
deviation on a case-by-case basis, if supported by data from the design
engineer. Such deviation may allow installation of the water main
closer to a sewer, provided that the water main is laid in a separate
trench or on an undisturbed earth shelf located on one side of the
sewer at such an elevation that the bottom of the water main is at
least 18 inches above the top of the sewer.
(3)
Crossings. Water mains crossing sewers shall be laid
to provide a minimum vertical distance of 18 inches between the outside
of the water main and the outside of the sewer. This shall be the
case where the water main is either above or below the sewer. At crossings,
one full length of water pipe shall be located so both joints will
be as far from the sewer as possible. Special structural support for
the water and sewer pipes may be required.
(4)
Exception. The Superintendent of Water, the Town Engineer or other duly authorized officials of the Town must specifically approve any variance from the requirements of Subsections E(2) and E(3) of this section, when it is impossible to obtain the specified separation distances. Where sewers are being installed and Subsections E(2) and E(3) of this section cannot be met, the sewer materials shall be water main pipe or equivalent and shall be pressure tested to ensure water tightness.
(5)
Force mains. There shall be at least a ten-foot horizontal separation between water mains and sanitary sewer force mains. There shall be an 18-inch vertical separation at crossings as required in Subsection E(3) of this section.
(6)
Sewer manholes. No water pipe shall pass through or
come in contact with any part of a sewer manhole.
(7)
Separation of water mains from other sources of contamination.
Design engineers should exercise caution when locating water mains
at or near certain sites such as sewage treatment plants or industrial
complexes. Individual septic tanks must be located and avoided. The
engineer must contact the Superintendent of Water, Town Engineer or
other duly authorized officials of the Town to establish specific
design requirements for locating water mains near any source of contamination.
F.
