The Elderville Water system was started in 1967 as a co-op corporation with only 394 water services. The system has grown to more than 3,032 water service connections with 2,740 active members. Our water comes from the City Of Longview and from water wells that we have established. At Elderville Water Supply we take our responsibility to provide quality, reliable drinking water to our customers seriously. We've been doing so for the last 45 years. Since the first pipe was laid in 1967, we've been dedicated to improving infrastructure and supply, whether it meant building plants to service a growing community, replacing pipe to strengthen aging systems, or drilling new wells.
