3-22.214.171.124 On Government installations, where in-place sanitary sewer is to be
incorporated into the project, it may be advisable to conduct a television inspection of
the sanitary sewer to verify its serviceability for the proposed project. If the line is not in
serviceable condition, its replacement or rehabilitation will be required. The Using
Service and USAR Installation will determine who is responsible for that work.
Government installation public works utilities may not have implemented or budgeted for
sanitary sewer utility maintenance or upgrade in all areas of the installation. Verification
of the sewer serviceability, and implementation and funding of repairs is required.
3-126.96.36.199 Sanitary sewer servicing OMS/AMSA facilities and wash platform will require
oil/water and grit separation. This is accomplished by installation of separate structures
within the sanitary system. Coordination with the mechanical discipline is required to
determine if the separator structures are to be installed within the building footprint or
outside the building.
3-188.8.131.52 Certain regions are using mechanical water and contaminant separators and
the local Regional Readiness Command environmental and construction coordinators
should be consulted.
3-184.108.40.206 Water mains include the on-site building services for domestic and fire
protection purposes from the building(s) to the water main system stub or connection
point. Interior looping of the system for fire protection may be desirable.
3-220.127.116.11 Water main sizing for fire protection purposes will be based upon flow and
pressure requirements for on-site hydrants and building fire suppression systems. It is
recommended that the fire protection main be no smaller than 8 in (200 mm) diameter,
and the standard hydrant lead no smaller than 6 in (150 mm) diameter. On-site water
storage reservoirs and/or fire booster pumps may be required for sites located in areas
of low system pressure.
3-18.104.22.168 Verify with local fire protection, utility and building officials whether
independent domestic and fire feeds external to the building are required, or if a single
feed can be separated inside the building. The requirements for indicator valves will be
verified with local building and fire protection officials, or with Government installation
fire departments and public works directorate.
3-22.214.171.124 In general, on-site fire protection and water supply system valves, hydrant
spacing, and sizing shall be in accordance with UFC 3-600-01. Preferred water main
pipe materials are corrosion-resistant materials such as PVC pipe, or ductile iron pipe
with corrosion protection and cathodic protection, if required. Pipe sections and bedding
shall be designed to withstand applied loads. Crossings of critical internal roadways,
which should not be disturbed or open cut in the future, will utilize a casing around the
underlying utility pipe.
3-126.96.36.199 Fire hydrant flow tests on the supplying water utility system should be
