Rhode Island Water Treatment

Water Quality in Providence & Central Rhode Island

Most public-water customers in the Providence metropolitan area receive treated surface water originating in the Scituate Reservoir system, while individual taps can still be influenced by service lines and household plumbing.

Communities in This Region

Providence, North Providence, Johnston and Cranston

Where the Water Comes From

Providence Water's source is the Scituate Reservoir complex. The utility treats and adjusts the water before distribution.

Public Water Does Not End at the Main

Service-line material, older plumbing and fixtures can influence tap water. For a lead concern, identify service-line material and use proper testing before selecting treatment.

Private Wells Still Exist

Not every property in central Rhode Island is on public water. URI identifies Johnston and western Cranston among areas where beryllium in bedrock may deserve additional testing consideration.

Common Home Treatment Objectives

Public-water objectives can include chlorine reduction, taste improvement, demonstrated lead reduction, drinking-water RO and hardness treatment when testing shows a need.
