A letter was recently sent out regarding backflow testing requirements. Due to an addressing issue, every customer in district 83 and 84 received a notice (see map attached). To clarify, only customers with a pool, irrigation system, or private well that is directly connected to the West Columbia water service will need to complete the annual test of the backflow preventer. A separate letter is going out to those customers. Please disregard the original letter dated July 1, 2020.
