The directors may invite the legislative body of any municipality within the district to designate a representative to serve as an associate director to advise and consult with them on all questions of programs and policy which may affect the property, water supply or other interest of the municipality. The board of directors may appoint, as they deem necessary, advisory committees to assure the availability of appropriate channels of communications to the board of directors, to persons affected by district operations, and to local, federal, state, regional and interstate special-purpose districts and agencies responsible for community planning, conservation commissions, zoning or resource development activities. The district shall keep the advisory committees informed of its work, and the advisory committees shall submit recommendations from time to time to the board of directors.
