How to verify an address

Use the source trail before relying on a filing route

  1. 1

    Identify the water provider from the property’s water bill, DPH inventory, or the state Exclusive Service Area map.

  2. 2

    Open the utility guide when available and check its review date, testing cadence, accepted form, and submission method.

  3. 3

    Confirm property-specific requirements with the utility before the appointment; hazards, device type, and deadlines can differ.
