Essential to a healthy, thriving and economically vibrant community is an abundant, reliable supply of water. The RWA plays an important role in meeting the public water supply needs of the region. We provide high quality drinking water to almost 430,000 consumers.
The RWA employs amulti-barrier approach to ensuring water quality. This approach focuses on watershed and aquifer management to protect the quality of our drinking water sources, treatment of the water prior to consumption, maintaining the distribution system which delivers the water to the tap, and monitoring the quality to assure compliance.
We draw most of the water from a series of reservoirs. We also pump water from wellfields. Before water ever reaches your tap, it goes through a multi-step process:
Protect: Our source water protection program focuses on pollution prevention and watershed management. We protect over 27,000 acres of land in the region and manage it carefully. We monitor the quality of the water and all activity on the surrounding land, watching for potential contamination of the lakes and aquifers that are the sources of your tap water.
Treat: Aquifer water is naturally filtered underground. Lake water is treated at our filtration plants. We use chlorine to kill microbes that might cause illness, and we add phosphate to minimize corrosion of pipes and fluoride to prevent dental cavities as required by Connecticut Department of Public Health (CTDPH) regulations.
Distribute: The treated or finished water is delivered to you through a 1,700-mile-long network of pipes, pumping stations and storage tanks. We carefully maintain this extensive network to ensure that high-quality water is available whenever you turn on your tap.
Monitor: Our water testing is stringent. In 2016, we performed more than 110,000 tests on over 10,000 water samples taken from numerous locations throughout our water distribution system, within our water treatment plants and int he lakes and aquifers where the water is stored prior to treatment. These samples are brought back to our state- and nationally-certified laboratory for microbiological testing as well as organic and inorganic chemical testing. The laboratory uses analytical devices as simple as pH meters or as complex as gas chromatographs and mass spectrometers. The results of these tests are compared to more than 175 state and federal standards and are reported to the CTDPH on a monthly, quarterly and annual basis, ensuring that only the highest-quality drinking water is provided to you.
Our pride is built on a heritage of providing service and water quality excellence to the communities we serve. Should you have questions concerning the quality of your water, please call our Customer Care Center at 203-562-4020. Thank you for allowing us to serve you.
