How to verify an address
Use the source trail before relying on a filing route

Identify the water provider from the property’s water bill, DPH inventory, or the state Exclusive Service Area map.
- 2
Open the utility guide when available and check its review date, testing cadence, accepted form, and submission method.
- 3
Confirm property-specific requirements with the utility before the appointment; hazards, device type, and deadlines can differ.
