In 2007, the 80th Texas Legislature amended Section 13.146 of the Texas Water Code to require each retail public utility that provides potable water service to 3,300 or more connections to submit a water conservation plan to the Texas Water Development Board no later than May 1, 2009. On April 27, 2009, the City Council adopted a City Water Conservation Plan and approved submission of the plan to the Texas Water Development Board.
As part of the Water Conservation Plan the city has implemented a Water Conservation Program. This program is being implemented in stages throughout the following year to include such initiatives as the year-round allowable hours for landscape watering, toilet replacement voucher program and water usage audits.
