A septic tank works by holding wastewater long enough for solids to settle (sludge) and oils/grease to float (scum). A three-chamber design improves this process through staged treatment:

Located above each chamber to allow for inspection and desludging (typically 500mm-600mm). Directs incoming wastewater into the first chamber without

When executing this design on-site, keep these tips in mind:

The three stages allow for higher sedimentation, leading to significantly reduced suspended solids entering the soakaway.

Are you working on a residential or small commercial plumbing project? The septic tank is the heart of any on-site sewage disposal system. While single-chamber tanks exist, a offers superior effluent quality and solids retention.
