North Alamo Water Supply Corporation is a legally chartered corporation operating under the laws of the State of Texas for the purpose of furnishing a potable water and wastewater utility service for rural residents of eastern Hidalgo County, Willacy County, and northwestern Cameron County as described in Certificates of Convenience and Necessity Nos. 10553 and 20645 (CCN). The Corporation’s CCN boundary encompasses 973 square miles and either surrounds or is adjacent to 16 cities and/or communities that operate public water systems. The system presently serves more than 44,900 meter connections, which include households, numerous businesses, 24 schools, and six other Public Water Systems, from six surface water treatment plants and one reverse osmosis treatment plant. The 44,900 meter connections represent an estimated population of nearly 180,000. The surface water treatment plants treat surface water conveyed by six irrigation districts. The original source of the raw water is the Rio Grande River. The reverse osmosis treatment plant treats brackish groundwater. Of these meter connections, approximately 2,000 are also served by the corporation’s wastewater system. The corporation’s operating policies, rates, tariffs and regulations are formulated and implemented by a nine-member Board of Directors elected by the members of the Corporation.
