Aerobic septic system maintenance and cleaning procedures: maintenance Guide for Fine bubble aeration septic systems. This ATU system article series provides designs and products for aerobic septic treatment units (ATUs) for onsite waste disposal, also called fine bubble aeration systems. We address aerobic septic system design, features, inspection, repair, and maintenance. Product sources are also listed.

Homeowners can reduce the operating cost of any septic system by conserving water use. An aerobic system retrofit may also extend the life of a drainfield - but be sure to read the caveats described in the next section on using an ATU to extend drainfield life.
Maintenance of Aerobic Septic Systems - How to Care for An ATU
You can reduce problems with your ATU and extend the system life by performing basic maintenance. Also see ATU Suppliers.

An aerobic system might be retrofitted to a conventional septic system in an attempt to extend the life of a conventional drainfield. Also, adding aeration or oxygen to a septic system may boost aerobic bacterial action in the biomat, improving the drainfield function. But it's not quite that simple.
We would look closely at any proposals to make this "improvement" to a conventional septic system. One reader wrote that their installer wanted to simply install an aerator in the original one-compartment septic tank. Our opinion was that unless a settlement chamber or tank outlet filter were installed the result of aeration and agitation in the primary single-chamber septic tank would be to push suspended solids out into the drain field where it would be clogged quite rapidly.
While there are a number of interesting pre-packaged advanced wastewater treatment systems on the market, a web search (in 2005 and again in 2006) does not turn up much on installation, operating, or repair costs. The manufacturers argue that each site is unique so installation costs vary. OPINION: we suspect that as with any costly but necessary product, some vendors just don't want to give the bad news up front. When we collect more explicit septic system failure and maintenance cost data we will post it at this website.
