The Water Authority operates and maintains a regional water delivery system capable of delivering 900 million gallons of water per day. Building and operating the large-scale infrastructure required to meet the region’s water needs now and in the future requires careful planning and technical expertise. The Water Authority uses a sophisticated approach to cost-effectively build, operate, maintain and secure its water facilities as an integrated system.
