On-site Sewage Management Systems

If you live in a dwelling house that is not connected to the main sewer, then chances are your yard contains an on-site sewage management system (OSMS). If this is the case, then you have a special responsibility to ensure that your system is working well.  The two most common on-site sewage management systems within the Upper Lachlan Shire are septic tanks and aerated wastewater treatment systems (AWTS).

The following brochures explain how these systems work and provide tips for ensuring the systems work effectively.
