connection that serves other sites.
(b) A campground owner shall determine peak instantaneous demands for
unthreaded convenience water outlets, water-using fixtures in service buildings, and
other water-using facilities served by the campground's water system using the
department's fixture method in the publication entitled "Michigan Criteria for
Subsurface Sewage Disposal," dated April 1994, or using other nationally recognized
methods for determining peak instantaneous demand. The publication may be obtained

bury of 3.5 feet or more than 3.5 feet in areas where the frost line typically extends
below 3.5 feet.
(4) A campground owner shall provide water under pressure to a campsite
occupied by a single sectional mobile home. A campground owner shall ensure that the
water distribution system piping is an adequate size to meet peak demands, as
determined in subrule (2) of this rule, while maintaining a minimum residual pressure
of 20 pounds per square inch.
(5) A campground owner shall ensure that a potable water supply system is
designed, installed, and maintained to prevent contamination from nonpotable water

ground stop and waste valves that have weep holes for use on the waterlines are not
(6) A campground owner shall ensure that any plastic waterline that is used in a
campground is made of a material approved by the department and has a minimum

the pipe, plastic fittings, and solvent cements are approved by NSF (National
Sanitation Foundation) International for potable water supply and bear the NSF
International seal of approval.
(7) A campground owner may locate an unthreaded convenience water outlet on a
site but shall not allow a direct connection of the outlet to a recreational unit.
(8) If a site water connection is proposed, then a campground owner shall also
propose and provide a site sewer connection, a mechanical sewage pump-out
facility, or an agreement with a licensed septic tank cleaner.
(9) A campground owner shall not make or allow an alteration to a
campground water system without prior written approval from the department. "An
alteration to a water system" means the modification of, or addition to, an existing
