Steps
Query https://arcgis.env.nm.gov/server/rest/services/ehb/onsite_wastewater_compliance/FeatureServer with ?f=json first to confirm the live layer list and exact field names before writing any parsing logic
Run a /query against the relevant layer with where=1=1&outFields=* to pull the full schema
Filter by county or facility identifier once you've confirmed the correct field name from the metadata response
Paginate with resultOffset/resultRecordCount to respect the service's maxRecordCount
Request geometry in the service's native spatial reference (NAD83) if you need it aligned with other NM state GIS layers
Known gotchas
This service is less battle-tested in public use than county-level examples — always call ?f=json against the live endpoint first rather than trusting a cached field list, including any list you're handed secondhand
New Mexico's program covers 'liquid waste permits' broadly, which includes septic/OWTS but isn't exclusively septic — filter on a permit-type field once confirmed, don't assume every record is a septic system
No authentication required, but as a smaller state-agency server, build in retry logic for intermittent timeouts
