Southern Region Waste Resource Authority (SRWRA)

SRWRA is a joint initiative between the Cities of Onkaparinga, Marion and Holdfast Bay (Constituent Councils). It was established in its current form, on 6 December 1998 and is responsible for providing and operating waste management services on behalf of these councils.

SRWRA’s detailed historical timeline


Councils of Brighton, Happy Valley, Marion, Noarlunga and District Council of Willunga and Meadows establish Southern Region of Councils (SROC).


On September 16, Pedler Creek Waste Disposal Depot is opened for receipt of waste.

1992 - 1994

Energy Developments Limited (EDL) and Southern Region of Councils (SROC) enter discussions and reach an agreement for the operation of a landfill gas power generation project.

1996 - 1997
  • Councils of Happy Valley, Noarlunga and Willunga combine to become the City of Onkaparinga.
  • Councils of Brighton and Glenelg combine to become Holdfast Bay.
  • Southern Region of Councils (SROC) resolves to change its name to SRWRA – members are City of Onkaparinga, Marion and Holdfast Bay.
  • Don Donaldson is the Chairperson.
  • Energy Developments Limited’s (EDL) landfill gas power generation project becomes operational.
  • SRWRA is established as a regional subsidiary, providing a cost-effective waste management role that meets strict environmental and community standards. A charter is established that sets out governance arrangements for the Authority.
  • Two representatives from each council join the board, and Mark Booth is the Chairperson.
  • We establish an operator’s agreement with Cleanaway to manage the landfill.
  • Pedler Creek Disposal Depot is now called the Southern Region Waste Disposal Depot (SRWDD).

A visitor’s boardwalk is constructed to provide tour groups with a safe way to visit our site. It is opened in September by the Hon. Robert Brokenshire.

  • With the new boardwalk in place, we begin to host educational tours for school students, university students and Council groups.
  • We plant 3,000 seedlings on the old, covered landfill cells and Les Perry is SRWRA’s Operations Manager.
  • The state government announces a commitment to Zero Waste to Landfill and Alternative Treatment Technologies. In light of this, Cleanaway and SRWRA begin to examine alternative waste treatment technologies.
  • SRWRA Board begins the process of evaluating the provision of domestic waste management services on a regional basis.
  • To date 53,000 trees have been planted on the SRWRA site.
  • The Energy Developments Limited (EDL) power station is generating around 2,900kWh and supplying electricity to approximately 3,000 homes and businesses. This equates to saving 9,857 tonnes of greenhouse gas per year.
  • A public drop-off area is established so that families can bring their waste to the facility.
  • SRWRA and Cleanaway continue to collaborate, and a Memorandum of Understanding (MoU) is established to assess the viability of introducing an Alternative Waste Treatment (AWT) system. The MoU includes plans for treating 80,000 tonnes of household waste per year. New technology is expected to deliver diversion rates of 80% and expand the landfill site.
  • In March 2004, SRWRA promotes the establishment of the ‘Waste Policy Forum’, a broad-based policy forum for southern Adelaide. This is supported by the Cities of Onkaparinga, Marion, Holdfast Bay, West Torrens, Unley, and Mitcham and aims to explore ways of advancing an integrated approach to manage the waste hierarchy.
  • Cleanaway begin using an innovative lining system, called Geo Composite Lining (GCL), for Cell 2 construction. Approximately 10mm thick, it provides a permeability rating comparable to around one metre of clay, therefore extending the life of the cell.
  • Three thousand more trees and shrubs are planted for site screening, and six new landfill gas wells are installed in Cell 2 by Energy Developments Limited (EDL).
  • SRWRA initiates a full ground water investigation to provide a comprehensive map of groundwater location on-site. This enables reference when planning future site works.
  • Brian Carr is appointed Chief Executive Officer.
  • The Waste Policy Forum is established with SRWRA as the facilitator.
  • SRWRA begins a detailed planning process to establish key objectives and core strategies intended to ensure business viability and achieve environmental, social and economic goals. SRWRA also begins setting aside funds for post closure liabilities.
  • On-site trials are conducted by Cleanaway to test easily sorted material and the type of products that may be extracted from the Commercial and Industrial stream. Over a 12-week period, 3,778 tonnes of material are processed, with a diversion rate of approximately 25% (938 tonnes) achieved. Predominant products were metals, hard plastic, timber, green waste, and concrete.
  • Cleanaway begins investigation into the construction of a new landfill cell (Cell 3).
  • Rock is crushed and screened on-site to provide a specific sized material for a drainage blanket in the new landfill cell.
  • We receive approximately 200,000 tonnes of waste materials, with 938 tonnes of recyclable material being removed from the waste stream in a trial basis.
  • Southern Region Waste Disposal Depot is renamed ‘SRWRA Landfill Operation’.
  • A stakeholder Perception Survey is undertaken by SRWRA. The following key areas are identified:
    • increased diversion of waste
    • slow filling of landfill to prolong the life of the site
    • priority use of landfill for Member Councils
    • the risk of contamination of surrounding environment
    • strong support for investment in additional waste infrastructure and at recycling and green waste treatment.
