All septic connections shall be made with SDR 35 gasketed sewer
pipe. Other rigid pipe of similar quality may be used only with prior
approval of the Building Inspector or Code Enforcement Official.
When replacing an existing sanitary system component, the component
being replaced must be installed in accordance with 10 NYCRR Appendix
75-A and the most current Nassau County Department of Health standards
to the extent practicable. If remaining structures on the property
are constructed of stacked cesspool block, all block structures must
be properly abandoned and replaced as above.
[Amended 9-20-2023 by L.L. No. 2-2023]
A. All new or substantially improved residential structures shall include
the installation of a new sanitary system.
(1) For
new or substantially improved structures constructed under building
permits issued prior to October 1, 2023, new conventional sanitary
systems may be installed or existing systems may be utilized only
if they conform to 10 NYCRR Appendix 75-A and the most current Nassau
County Department of Health standards and were legally installed within
the last 10 years.
(2) For
new or substantially improved structures constructed under building
permits issued on or after October 1, 2023, new IA Sanitary Systems
must be installed.
Where on-site conditions of existing structures do not allow
for conformance to required clearances and/or setbacks, such clearances
and/or setbacks for new on-site systems may be modified only with
prior approval of the Building Inspector or Code Enforcement Official.
All new sanitary system installations constructed on or after
the effective date of the enactment of this article shall be inspected
and approved by the Building Inspector or Code Enforcement Official.
In instances where, in the opinion of the Code Enforcement Official,
spatial constraints, soil composition or other site conditions prevent
the installation from conforming to generally accepted practices,
the Code Enforcement Official may require alternate design and certification
by a duly licensed design professional.
