How to Find Your New Jersey Water System
Before you can trust any water-quality claim, confirm the exact system serving your address.
Short answer: Check your water bill for the provider name, then confirm it in the NJDEP Drinking Water Viewer by searching your system name, county, and municipality until you find a matching Public Water System ID (PWSID).
Who this is for: any New Jersey resident, renter, buyer, or landlord who wants to identify their water provider before reading a report or requesting service.
New Jersey context
New Jersey has municipal systems, municipal authorities, investor-owned utilities, regional systems, and noncommunity systems, and boundaries frequently cross municipal lines. Some towns are served entirely by one system; others have multiple systems serving different neighborhoods. Your town's name is a starting point, not a confirmation.
Step-by-step
- Check your water bill or landlord/property records for the provider's name.
- Go to the NJDEP Drinking Water Viewer and search by system name, county, and municipality.
- Confirm the system ID (PWSID) and that the mapped service area includes your address.
- Note the system's official name exactly as listed — you'll need it to find the correct CCR.
- If you can't find a match, contact your municipality or local health department for help identifying your provider.
What the official source says
NJDEP's Drinking Water Viewer is the authoritative statewide tool for identifying public water systems and their service areas in New Jersey. It is updated by NJDEP directly, so always treat it as more current than a search engine result or a third-party site.
Common mistakes
- Assuming your town's name is also your system's name
- Using an old bill from a previous resident or owner
- Stopping at the first system that comes up in a general web search instead of confirming in the Viewer
When professional help is appropriate
If you cannot determine your system after checking the Viewer, your municipal clerk's office or local health department can typically confirm it directly.

What if two systems seem to serve my town?
This is common in New Jersey. Confirm which one maps to your exact address in the Drinking Water Viewer rather than assuming based on your neighbors or a general town-level search.
