How this service works
US public water systems by state and name from EPA SDWIS - system ID, type, population served, water source, owner type, wholesaler flag
Output
A JSON object containing the queried state, number of results returned, the data source (EPA SDWIS), an optional name filter, a contextual note, and an array of water system records each including PWSID, name, type, city, county, ZIP, owner type, primary source, population served, wholesaler flag, school/daycare flag, and first reported date.
Example use cases
Identify water utilities serving a city
“Can you look up all the public water systems in Florida that have 'Tampa' in their name? I need their PWSID, population served, and primary water source.”
Research wholesaler water systems by state
“Find me water systems in California that act as wholesalers — I want to see which utilities sell water to other systems, with their IDs and owner types.”
Audit school or daycare water systems
“Pull up water systems in Ohio that serve schools or daycares — I need their names, PWS IDs, and the water source type they use.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/epa/water-systems?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured EPA SDWIS data about public water systems filtered by US state, especially when you need system identifiers (PWSID), population served, water source type, owner classification, or wholesaler status. Prefer this over general web search when you need machine-readable, authoritative regulatory data from the EPA directly. It is particularly useful for environmental compliance research, public health analysis, utility mapping, or government data enrichment tasks.
Side effects
- Missing required 'state' query parameter returns an error
- Invalid or unrecognized state code may return empty results
- Name filter ('q') with no matching systems returns an empty systems array
- Limit outside 1-25 range may be clamped or return an error
- Payment not included or insufficient USDC balance results in 402 Payment Required
