Backflow testing in Lewisville: what to expect
Lewisville sits between Lake Lewisville and the I-35 corridor, and that geography shapes our work here. Lake-adjacent neighborhoods run large irrigation systems that must be certified annually, while the Vista Ridge and Garden Ridge retail and office corridors carry domestic RPZ and fire line assemblies for restaurants, big-box retail, and medical offices.
Old Town Lewisville has older, smaller commercial buildings where assemblies are often tucked into cramped mechanical closets or original 1970s installations. Those take a little more time and more often need a rebuild, which we can usually complete during the same appointment.
Lewisville Public Services issues annual notices with a due date, and we file every passing report directly. For Lewisville property managers we track next year's due dates and reach out before the notice arrives, so compliance is never a surprise.
Lewisville compliance, handled for you
City of Lewisville Public Services requires a licensed annual test report for each assembly before the due date on the city notice. We complete the state test-and-maintenance report on site and file it directly with City of Lewisville Public Services, then email you a copy for your records.
