On-Site Sewage Management

Revised OSSM Strategy and Guidelines

The revision of the OSSM Strategy has been completed and adopted by Council. This revised OSSM Strategy will come into effect from 1 February 2018 and after this date the old OSSM Strategy is no longer to be used. A workshop of the revised OSSM Strategy and Guidelines will be held with the local wastewater industry before the Strategy comes into effect. It is optional to use either Strategy from now up to 1 February 2018.  Further information in regard to the workshop will be provided soon.

On-site Sewage Management Systems (OSSMS) are required in all non-sewered areas. There are over 4,000 OSSMS installed in Ballina Shire.

OSSMS include septics, aerated wastewater treatment systems, composting toilets, reedbeds, sand filters, biological filters, membrane reactors and greywater systems.

These systems treat wastewater from premises before applying the effluent to land. Effluent land applications include absorption/evaporation beds or subsurface irrigation.


These factsheets will assist the homeowner, wastewater consultant, plumber & drainer to design, install and maintain the on-site sewage management system.

OSSM Owner Education Booklet

The OSSM owner educational booklet provides information for existing and future OSSM owners on the fundamentals on how to choose an OSSM system, how it works and how to maintain the system. 

Soil Factsheets

The information in these soil factsheets are general in advice and have been obtained from the Victorian Resources Online website, Department of Primary Industries Victoria.  © State of Victoria, Department of Primary Industries 2012 Reproduced with permission.  This information may be of assistance when preparing reports involving soil assessments on properties where it is proposed to install on-site sewage management systems.

Forms and Checklists

OSSM Suitably Qualified Person Application Form (pdf)
If you intend to conduct site and soil assessments, design OSSM systems and/or service Aerated Wastewater Treatment Systems (AWTS) within the Ballina Shire region then you are required to be a suitably qualified person.

OSSM Design Producer Statement (pdf)
This On-Site Sewage Management (OSSM) Design Producer Statement form is to be submitted to Council’s Public and Environmental Health Section, when deemed necessary by Council, for new or upgraded works related to an OSSM system.

OSSM Installation and Minor Alterations Certification Form  (pdf)
This Installation & Minor Alterations Certification Form is to be submitted to Council's Development and Environmental Health Group for the purposes of certifying any minor alterations to the approval to install for new or upgraded works related to an on-site sewage management system (OSSMS).  This form verifies that the OSSM designer has approved the minor alterations.  Any alterations to the approved installation that are not of a minor nature will require an amended application to be lodged with Council.  Examples of minor alterations include - change from reln trenching to slotted pipe, change from distribution box to indexing valve, change of manufacturer from one secondary treatment system to another equivalent, minor relocation of effluent land application area.  Contact the Development and Environmental Health Group for clarification to determine if your situation is a minor alteration.

OSSM Compliance and Commissioning Certification Form (pdf)
This form is to be used for all new & upgraded On-site Sewage Management Systems (OSSM) installations. The certification form is to be filled out by the installer of the OSSM and must be inclusive of the effluent land application arrangements.

OSSM Inspection Checklists

These checklists are a guide and are recommended to be used when a suitably qualified person (ie licenced plumber and drainer) is engaged by the property owner to inspect their OSSM system for satisfactory operation eg sale of property. Further checklists will be developed in the future to cover different types of OSSM systems and installations.

Groundwater Bores Location

To check for the location of the nearest licensed groundwater bores click on the link below to take you to the NSW Waterinfo website:

Drinking Water Catchment Areas - Application Process

To check if a property is within the Drinking Water Catchment Area of the Shire:

  1. Firstly click on the “Overview Map “ to determine where the Drinking Water Catchment Areas are located.
  2. Then select the particular Drinking Water Catchment Map that is closest to where your property is located, for confirmation.
  3. If the property is within the Drinking Water Catchment Area then refer to the Rous Water On-Site Wastewater Management Guidelines for application requirements.

Drinking Water Catchment Maps

Note:  There are four drinking water bore sites within the Shire with a 250m radius catchment protection zone around each bore.  If your property is located within this protection zone and you intend to install a new or upgrade an existing OSSM system then please contact Council to determine the application requirements.

Contact Council's Development and Environmental Health Group if you need further clarification.

Priority Oyster Aquaculture Areas

If you are intending to upgrade or install a new OSSM system, in close proximity to the Richmond River or tributary stream, then you must determine if the property is within the Priority Oyster Aquaculture Area zone of influence.  When a property is within this zone of influence then further OSSM design specifications may be required to ensure that there are no impacts on the Priority Oyster Aquaculture Areas.

The OSSM consultant is to refer to the NSW Department of Primary Industries – Fishing and Aquaculture website for the NSW Oyster Industry Sustainable Aquaculture Strategy and Priority Oyster Aquaculture Area Maps.

The following facts sheets have been created to assist OSSM consultants:
