Factors including size, shape,
appearance and anticipated
drainage requirements need
to be taken into account in
planning e昀昀ective drainage
solutions. Design is usually the
responsibility of consulting
engineers familiar with the
昀氀oor construction, 昀氀oor 昀椀nish,

International regulations and
local building codes must be
observed for all sanitary and
other drainage installations so
it is recommended these are
considered as the 昀椀rst step.
As a matter of good practice
drains should be considered
for any location where
water is supplied or where
surface drainage must be
accommodated.
To prevent foul air from
entering a building a trapped
gully may be used and various
types are available Bell, Bottle,
P and S. In other cases a nontrapped gulley may be used
with a trap installed in the
drain line.
