In May 2016, an agreement was reached between the LGA CWMS Subsidy Fund and the Department of Health & Welfare (DHW) to share costs in updating and revising the CWMS Design Criteria Documentation that is made available to all parties involved in the design, construction and maintenance of CWMS systems across South Australia.
This decision to jointly review and rewrite the design criteria was important because;
- The existing documentation was outdated and needed to include the nationally adopted WSSA Code.
- A number of compliance and regulatory requirements had changed.
- Consultants lacked clear understanding of certain elements of the codes particularly relating to Hybrid Schemes.
- The existing Code needed to reflect contemporary views and practices associated with collection, treatment and reuse of wastewater for the benefit of communities.
The CWMS Management Committee engaged Wallbridge Gilbert Aztec (WGA) to undertake the revision under the direction of a qualified working party comprising:
- Richard Gayler/Mike Meachan - LGA CWMS Committee
- Tony Farror/Nina Allen - DHW
- Nathan Silby - Wallbridge Gilbert Aztec
A Draft Consultation document was completed in February 2017 and presented to the LGA CWMS Management Committee for consideration and feedback.
The CWMS Management Committee approved distribution of the Draft CWMS Criteria to:
- WARDA (a CWMS Cluster alliance within WIA specifically dedicated to CWMS)
- Relevant State Regulatory Bodies
- Selected (experienced and qualified) Local Government STEDS Councils (i.e. Barossa, Mt Barker, Alexandrina etc.)
The Draft Design Criteria Document was issued to the relevant affected parties seeking comment and input in December 2017 and a follow up workshop was held at the offices of DHA on 5th February 2018. Further feedback was gathered following this workshop.
The working party received 11 written submissions raising a total of 269 individual comments in respect to the draft CWMS Criteria.
Submissions were received from:
- Mid Murray Council
- Alexandrina Council
- Adelaide Plains Council
- Mount Barker Council
- Factor UTB
- Alano Water
- Tonkin Consulting
- HDS Consulting
- The Office of the Technical Regulator
- The Department of Health & Welfare
- TAFE SA
All feedback was considered and where materially important, incorporated into the final version of the South Australian Community Wastewater Management System (CWMS) Design Criteria.
The South Australian Community Wastewater Management System (CWMS) Design Criteria is now available for all parties involved in the design, construction and maintenance of CWMS systems across South Australia.
