Wastewater Treatment Plants with SPDES Permits in New York

A dataset of wastewater treatment facilities operating under New York State Pollutant Discharge Elimination System (SPDES) permits. It is published by data.ny.gov and includes facility names, permit numbers, design flow rates, and precise geolocation data. The dataset is actively maintained, with updates recorded as recently as April 2026.

Use Cases

• Mapping facility locations using the 'Longitude' and 'Latitude' columns for spatial analysis.
• Analyzing treatment capacity distribution by 'County' or 'City' based on 'Average Design Hydraulic Flow'.
• Tracking regulatory compliance by linking 'Facility Name' to its specific 'SPDES Permit Number'.
• Categorizing plants by their discharge type using the 'Ground or Surface' and 'Plant Type' fields.

Strengths

• Includes precise geospatial coordinates ('Latitude', 'Longitude') for mapping.
• Contains specific operational details like 'Average Design Hydraulic Flow' and 'SPDES Permit Number'.
• Published by an authoritative government source (data.ny.gov).

Limitations

• Key metadata like row count, file size, and license are consistently missing across all platforms.
• The temporal coverage of the data itself (e.g., permit issue dates) is not specified.
