Design Standards for Intermediate-Sized Wastewater Treatment Systems--Statewide and Lake George Design Standards (2014)
The 2014 New York State Department of Environmental Conservation Design Standards for Intermediate-sized Wastewater Treatment Systems (Design Standards) have been prepared to provide wastewater treatment system design professionals, treatment system owners and operators, and regulators with guidance on the design, operation and maintenance of intermediate-sized wastewater treatment facilities. These intermediate-sized systems serve medium sized facilities discharging to surface and ground waters, cluster housing and other multi-home developments, and POTWs that discharge to groundwater. Excluded are residential systems (individual home septic systems) and large Publicly Owned Treatment Works (POTWs) that discharge to surface waters.
The principal goal of the Design Standards is to provide design criteria for building wastewater treatment systems that protect the water quality of groundwater and surface water. The Design Standards are also intended to aid designers in the preparation of complete project submissions (map, plan and report) and improve the efficiency of project review by regulatory agencies. The updated Design Standards consider energy efficiency and the life cycle costs of the facilities.
The need to update the Design Standards has been heightened by the recent development of many new technologies for the onsite or near site treatment of wastewater. These developments have arisen from special needs, including the replacement of failing systems on limited sized sites, lighter weight construction materials and lower-cost sewage collection and treatment for remote or isolated locations; and special considerations for environmentally sensitive areas.
LAKE GEORGE DESIGN STANDARDS FOR WASTEWATER TREATMENT SYSTEMS
The New York State Department of Environmental Conservation (NYSDEC) is making available for review a draft version of the Lake George Design Standards for Wastewater Treatment Systems (PDF 4.6 MB).
These Design Standards are only applicable in the Lake George Basin for treated sanitary sewage, without admixture of industrial wastes, discharging to groundwater.
