Questions this answers
2 · best fit firstFor an authority demonstrably resolved through the responsible-entity AUTHORITY_NAME record, the 2022 CWNS files associate that authority by CWNS_ID with infrastructure explicitly classified as FACILITY_TYPE='Treatment Plant'. This directly supports a regulator-attributed wastewater-treatment infrastructure responsibility/activity classification at facility grain. It is not a NAICS or SIC classification and does not establish legal ownership, day-to-day operation, current status, every activity of the authority, or private-industrial treatment coverage; retain the raw facility type, responsibility relation, survey vintage, and resolution limits.
EPA's standing nationwide 2022 CWNS files can be joined by CWNS_ID: POINT_OF_CONTACT identifies the single responsible entity and its AUTHORITY_NAME; FACILITY_TYPES identifies records whose FACILITY_TYPE is Treatment Plant; FACILITIES supplies facility name, owner type, and date last modified; and PHYSICAL_LOCATION supplies wastewater-infrastructure address and NAD83 coordinates. For an authority resolved by exact name and geography, this provides a dated regulator-observed footprint of treatment-plant infrastructure for which it is the responsible entity. It does not prove legal ownership, operator status, current operation, brand affiliation, private-industrial treatment coverage, or a complete enterprise footprint; preserve facility grain, 2022 survey vintage, row date, relationship basis, and name-resolution limitations.
