The drainage of this group of houses is as follows:—The four
houses in F Road drain separately into the common pipe B to C, and
the two houses in A Street drain separately into the common pipe A
to C. At the point C both these common pipes are received by a Y
junction and continued by a single main pipe passing under the corner
house into the public sewer F Road at D.
It will be admitted by all that the common pipe B C is a single
private drain pipe under Section 19 of the Public Health Acts
Amendment Act. By the decision in the Wood Green case, the
common pipe A C is a sewer. But what is the character of the pipe
C D? Does the single private drain enter the sewer A D at C, or
does the sewer A C enter the single private drain B D at C? It
must be remembered that the point of union is a common Y junction,
so that the pipe C D is as much a continuation of the one as of the
other. The Court of Appeal cases do not aid in the elucidation of this
query.
(3) Five houses, all belonging to different owners, drain into a
chamber at the rear of the middle house and thence by a main pipe
passing beneath the middle house into the sewer in the road as shown
in the sketch.
