				  small enough to be cleaned and returned to service in 1 day, two or more cells
				  are required.
b. The "red water"
				  filter shall have sufficient capacity to contain, above the level of the sand,
				  the entire volume of wash water produced by washing all of the production
				  filters in the plant, unless the production filters are washed on a rotating
				  schedule and the flow through the production filters is regulated by true rate
				  of flow controllers. Then sufficient volume shall be provided to properly
				  dispose of the wash water involved.
c. Sufficient filter surface area should be
				  provided so that, during any one filtration cycle, no more than 2 feet of
				  backwash water will accumulate over the sand surface.
d. The filter shall not be subject to
				  flooding by surface runoff or flood waters. Finished grade elevation shall be
				  established to facilitate maintenance, cleaning and removal of surface sand as
				  required. Flash boards or other non-watertight devices shall not be used in the
				  construction of filter side walls.
e. The filter media should consist of a
				  minimum of 12 inches of sand, 3 to 4 inches of supporting small gravel or
				  torpedo sand, and 9 inches of gravel in graded layers. All sand and gravel
				  should be washed to remove fines.
f. Filter sand should have an effective size
				  of 0.3 to 0.5 mm and a uniformity coefficient not to exceed 3.5. The use of
				  larger sized sands shall be justified by the designing engineer to the
				  satisfaction of the state health officer.
g. The filter should be provided with an
				  adequate under-drainage collection system to permit satisfactory discharge of
				  filtrate.
h. Provision shall be
				  made for the sampling of the filter effluent.
i. Overflow devices from "red water" filters
				  shall not be permitted.
j. Where
				  freezing is a problem, provisions should be made for freeze protection for the
				  filters during the winter months.
k. "Red water" filters shall comply with the
				  common wall provisions contained in §177 of this Part, which pertain to the
				  possibility of contaminating treated water with unsafe water.
