Ark. Code Ann. § 14-234-105: Alteration despite zoning regulations

Any municipality maintaining facilities in an area zoned subsequent to the construction of the facilities may add to, alter, expand, or change the facilities upon the land now used for those purposes, or upon lands immediately adjacent thereto, without regard to the zoning regulation for the area if the operating authority of the waterworks system deems the action necessary for the proper operation of its system.
