Aerobic System Service in Leesburg deals with an aerobic treatment unit (ATU) that needs regular checks of its air pump, alarm and treatment stages.

Aerobic System Service and Leesburg's homes
Leesburg has about 8,371 single-family detached houses, and some homes on septic use an aerobic treatment unit instead of a conventional tank. ATUs rely on an air pump and alarms, so they need regular maintenance visits, not just pumping.
None of the 5 companies listed here has its office in Leesburg itself; they serve it from Clermont, Kissimmee, Lady Lake and other towns. 3 of the 5 also offer septic repairs, useful because aerobic units have pumps, alarms and controls that need repairing over time; our listings for Liberty Septic LLC and Suburban Septic Service don't include it.
