If you have an existing septic tank then there may be no need to install a full sewage treatment unit. If the septic tank is integral, i.e. does not leak water in or out, then it is possible to include it as part of a three stage sewage treatment unit by adding a septic tank conversion unit . The septic tank becomes the primary settlement tank and you add on the missing biozone and final settlement zone in the form of a small conversion unit. This unit is connected to the septic tank's outlet and the effluent that it discharges is clean enough to go directly to a watercourse with E.A. Discharge Permit or Exemption These units are available as gravity discharge or as pumped outlet discharge if you need a higher discharge level.

There are distinct advantages in placing septic tanks in front of any sewage treatment unit as they intercept all slowly degradable items such as tampons, baby wipes, etc. which can cause problems in some sewage treatment systems.

There are three types of add-on septic tank conversion units.

You can also purchase in-tank adaption units, but we tried these systems and stopped promoting them due to very poor quality effluent and too many emergency call-outs for blocked air lift pipes, overflowing manholes and similar problems. However, we can supply an in-tank conversion unit if specified.
