Rhode Island General Laws Title 46. Waters and Navigation § 46-15-5. Water supply to other states

(a) No municipal water departments or agencies, special water districts, or private water companies shall transport or carry through pipes, conduits, ditches, or canals, the waters of any fresh water lake, pond, brook, river, stream, or creek in this state or any well, subsurface, or percolating waters of this state into any other state for use therein except where the consent in writing of the water resources board has been obtained.

(b) A petition in writing for that consent must be filed with the water resources board accompanied by such plans and documents as the water resources board may require. The provisions of § 45-15-4 shall, so far as practicable, apply to all proceedings to be had subsequent to the filing of the petition as if the petition were one filed pursuant to the provision of § 46-15-4.

(c) The water resources board shall enforce the provisions of this section, and the superior court, by injunction, may, upon an application of the director, prevent any unauthorized diversion or transportation.

(d) Nothing contained herein shall be construed to affect any contracts or other arrangements in existence on September 1, 1990, wherein a municipal water department or agency, special water district, or private water company is supplying to and/or purchasing water from any agency or other entity in another state.
