In accordance with new state law, the Agency will be contacting you to schedule a hazard assessment to determine if there is a need for a backflow device to be installed at your property.
While the Agency has always conducted assessments, new state law requires the Agency to visit EVERY property & conduct an assessment.
All backflow devices must be installed immediately adjacent to the meter, some backflow devices may need to be relocated.
