The mayors of Houston, Dallas and Austin told lawmakers on Tuesday that they support a proposed $2 billion fund to finance water projects across the state and would like to see less red tape and more conservation efforts.

Houston Mayor Annise Parker told the House Natural Resources Committee that she supports using money from the Rainy Day Fund to create a water development bank that would help local authorities build new water projects and finance conservation efforts. Houston has invested in numerous water projects and delivers 495 million gallons a day to 470,000 customers.
