Aerobic System Service and Sanford's homes
Sanford has about 13,983 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 Sanford itself; they serve it from Kissimmee, Orange City, Orlando and other towns. 4 of the 5 also offer septic repairs; our listing for Liberty Septic LLC doesn't include it. One states 24/7 service on their own website.
