In 1981 Grand Prairie Water Users Association was formed and over the next five years contracts, easements, loans and construction of the system took place. In October 1986, water was made available to 600 customers in rural northeast Lonoke County. The Grand Prairie Water Users Association grew over the next 23 years to see an increase from the 2 groundwater wells and ½ million gallon per day treatment facility to 8 groundwater wells and three treatment facilities with an overall capacity of 2.5 million gallons per day. Over the last 23 years the customer base has increased from the original 600 customers to 2,350.

The Bayou Two Water System was developed in 1987 and was originally intended to be part of the Grand Prairie Water System; however, due to financing challenges the two systems were unable to start as one. Grand Prairie provided management service to the Bayou Two system from 1994 to 2006. The Bayou Two Water System customer base increased from the original 350 customers to 1,550.

In 2006, the Bayou Two system merged with Grand Prairie forming the Grand Prairie Bayou Two Public Facilities Board with a total customer base of 3,900. Bayou Two’s water source had previously been through Jacksonville Water but since the merger lines were connected to eliminate the purchase of water from Jacksonville. Water rates between the two systems are expected to levelize in January of 2010. To ensure the Grand Prairie Bayou Two customers have a continuing viable source of water, we have been working over the past 16 years to develop the Lonoke/White project that will bring surface water to this area from Greer’s Ferry Lake.

In 2012, Grand Prairie Bayou Two Public Facilities Board became Grand Prairie Bayou Two Public Water Authority.
