Where a public sewer is available and accessible in a street,
alley, easement or thoroughfare to a building or premises abutting
thereon, the liquid sewage wastes from any plumbing system in said
building shall be discharged into the public sewer unless otherwise
prohibited, except that where a place of residence is so located that
a gravity connection from the plumbing above the first floor thereof
to the street sewer is not possible or such place of residence is
located more than 150 feet from the nearest public sewer, a separate
sewerage system may be maintained which otherwise complies with City,
county or state health laws, codes or regulations. Immediately after
the construction of a sewer connection every sewage tank, cesspool
or privy vault shall be emptied, cleaned, disinfected and filled with
clean mineral soil, rock or gravel. Where a public sanitary sewer
is not accessible, a building permit shall not be issued without submission
of a copy of the written approval of the Westchester County Commissioner
of Health, indicating that the premises may be adequately sewered
by a separate sewage disposal system. The further approval of the
Common Council of the City of Rye is required for such separate disposal
systems. In addition thereto there shall be an annual inspection of
all private sewage disposal systems by a contractor duly approved
by the Westchester County Commissioner of Health on all properties
bordering on all watercourses, including Long Island Sound, Milton
Harbor and all tributaries thereto, and wherever else directed by
the Sanitation Committee of the Common Council. A written certificate
of such inspection shall be submitted to said Committee for such action
thereon as it may direct.
