Water Line Rules

State guide

Rhode Island

Rhode Island has a statewide lead-service-line framework in its Lead Poisoning Prevention Act, and RIDOH now publishes both consumer lead information and a statewide transparency dashboard for service-line inventories. The state law defines the public side as water main to curb shutoff valve and the private side as curb shutoff valve into the building, which matches Providence Water and Warwick utility materials.

Checked against official sources on October 4, 2026. Rules and links change; confirm with the office listed before you act.

Try a ZIP like 30303, “Travis County” or “Columbus, OH”
Who usually owns the water service line
Rhode Island law generally follows a split where the utility owns the line from the main to the curb shutoff valve and the property owner owns from the curb shutoff valve into the building.

Permits for repair or replacement
Warwick’s published rules say the owner’s portion from curb stop to meter is installed and maintained at the owner’s expense by a master plumber licensed by the State of Rhode Island; Providence Water advises customers to contact a licensed plumber for service-line work.
Assistance programs
Rhode Island law says, to the extent funds are available, the Rhode Island Infrastructure Bank shall use IIJA funds to meet eligible private-side replacement cost; Providence Water also says it will replace the public side at no cost when the customer replaces the private side.

What to do next

  1. Check RIDOH’s lead pages and dashboard, then ask your water supplier whether both the public side and private side for your address are classified as lead, non-lead, or unknown.
  2. If your property is in Providence Water territory, review the utility’s ownership and replacement-program pages before hiring a plumber for private-side work.
  3. If you are in Warwick, confirm Water Division requirements and use a Rhode Island licensed master plumber for owner-side service-pipe work.
