Atom Consulting facilitated a criticality review of the water, sewage treatment and recycling plants for Parkes Shire Council.

The equipment at each plant was reviewed in workshops with Council management and operating staff.

The project outcomes were:


We facilitate quarterly water quality meetings and teleconferences for Council's Drinking Water Management System (DWMS). In each meeting, we review key components of the DWMS including operational and verification data, customer complaints, and any incidents or treatment challenges. The results of these meetings are used to prepare the DWMS annual report, giving Council a greater understanding of their system.

NSW Department of Primary Industries, Urban Water Branch, engaged us to lead the development of the ‘NSW Recycled Water Management System Guidance’. We facilitated a series of stakeholder workshops, developed the guidance document and created a number of supporting fact sheets to help NSW improve the safe use and governance of recycled water.

We were engaged by Coffs Harbour City Council to develop a risk based Recycled Water Management System (RWMS) for their recycled water scheme. Through a process of interview, document review, treatment plant and end-user site inspections, we carried out a gap analysis audit of the system. We also carried out a workshop risk assessment, involving a number of external stakeholders, facilitating the project with appropriate engagement to ensure the best result for the council.

Tamworth Regional Council engaged us to facilitate water quality risk assessments for Barraba, Bendemeer, Nundle and Manilla Water Treatment Plants, as required by the NSW Public Health Act 2010. Our assessment not only assisted the council to meet regulatory requirements, but ensured they were on the front-foot for managing any potential risk or regulatory issues.

We led an intensive tracer study to gather data for use in a hydraulic model and water age study to improve Council’s understanding of the reticulation system. This enabled council to make better decisions to keep their community healthy.

We created a framework to control microbial risks from pipeline repair or renewal for WaterRA. We collected data from water utilities across Australia regarding their pipe break procedures and protocols, in order to develop the framework which would allow for safer management of pipe breaks.
