How
can a 3" pipe
carry the effluent for 300 homes?
The minimum
recommended diameter of the SBS™ main
piping system is 75 mm or approximately 3". The
Manning Formula is used to determine the size the effluent
receiving system and is sensitive to design flows and pipe
gradients. As with historic systems, the pipe sizing increases
incrementally with increased design flows. Depending upon the
size and land development pattern, the main pipe sizing will
vary from a minimum of 75 mm to a much larger diameter for
many thousands of total downstream connections. In addition,
the sewer is completely sealer and does not permit infiltration
or other inflows to enter the system.
