New York State Design Standards for Intermediate Sized Wastewater Treatment Systems

The New York State 2014 Design Standards for Intermediate Sized Wastewater Treatment Systems provides design engineers with guidance on how to design wastewater treatment facilities to comply with State SPDES regulations. This manual is a reference for both the Private/Commercial/Institutional (SPDES) General Permit, as well as individual permits for sanitary waste.

The New York State Design Standards for Intermediate Sized Wastewater Treatment Systems (PDF 4.4 MB). This edition of the Design Standard is intended to incorporate newer technology, as well as provide more design and installation guidance for wastewater treatment facilities. Many valuable comments were received during the public notice period and are incorporated into the updated sections, as appropriate.

This 2014 Design Standard is applicable for municipal, private, commercial and institutional SPDES wastewater permits. The 1988 Design Standard will remain in effect as the design guidance for the Private Commercial and Institutional General Permit, i.e. SPDES General Permit 0-05-001. When that general permit is re-issued, the 2014 Design Standard will be the applicable design guidance for that permit.
