The North Carolina Board of Irrigation Contractors' was established by legislation which became effective January 1, 2009. The board oversees the licensing of Irrigation Contractors in North Carolina. The purpose of licensure is to protect the public health, safety and welfare and to promote the efficient use of water. The new licensure law comes into full effect on June 30 2009.

According to the recently enacted licensure law, no person shall engage in the practice of irrigation construction or contracting, use the designation 'irrigation contractor,' or advertise using any title or description that implies licensure as an irrigation contractor unless the person is licensed as an irrigation contractor. All irrigation construction or contracting performed by an individual, partnership, association, corporation, firm, or other group shall be under the direct supervision of an individual licensed by the Board.
