Austin Water is engaged in aggressive water conservation and climate programs aimed at reducing water use and addressing the water-energy nexus, while continuing to provide reliable and sustainable water and wastewater service to customers. The programs include: mandatory watering restrictions; installation of renewable energy at plants and facilities; and implementing employee ideas to save energy in operations – all while dealing with the worst drought since the historic drought of the 1950s.
