Business continuity and maintaining effective water and wastewater services

Unprecedented droughts, bushfires and water quality extremes. Now unprecedented pandemics…. What next? What would happen if your operations team were unavailable? Do you have a plan in place to ensure business continuity and maintaining effective water and wastewater services?

2020 Frontline Regional Water Challenges

The last few weeks have presented extremely challenging water quality conditions for large parts of NSW due to the unprecedented combination of drought, bushfires and flooding. These impacts are likely to continue to impact water quality in catchments for a number of years. Hunter H2O continues to provide technical and on-site operational support assistance for councils across NSW to help resolve and manage challenging water quality and treatment issues.

Over the course of these events we have identified a number of common issues outlined in our 2020 Frontline Regional Water Challenges document.

Hunter H2O Sustainability Policy

The Hunter H2O 2025 Strategy for an agile and sustainable Hunter H2O is supported by our four strategic pillars: Being Customer Connected; Compelling Employee Experience; Our Market Edge and Sustainable and Agile. These pillars map out our transition to a customer connected, more agile and sustainable organisation. Through our strategy execution Hunter H2O is committed to continually reviewing and improving sustainability practices.

We recognise the importance of the United Nations Sustainable Development Goals and strive to meet the intent in whatever way we can.

Hunter H2O Inclusion and Diversity Policy

At Hunter H2O we value diversity of thought and experience and believe that our inclusive and collaborative culture contributes to our success. We are a diverse workforce that reflects contemporary, multicultural Australia. We celebrate and promote this diversity as a strength of our business.

Hunter H2O primary service area information sheets:

High iron, high co2 groundwater – a difficult combination

Aqwest engaged Hunter H2O (Formerly Hunter Water Australia) to review pH correction and water stability options, to raise the current lower pH levels to the target of 7.6 and reduce CO2 levels to 15 mg/L. A paper by Clara Laydon.

Utilising modelling projects to consolidate system data – a knowledge management exercise

Hunter H2O (Formerly Hunter Water Australia) have developed several systems to not only compile and consolidate the knowledge in an accessible, understandable format, but also to allow the client to utilise this knowledge for other projects and as general reference tools.

Ozone-enhanced particle removal in drinking water treatment

High residual particle counts in filtered water have implications for potential breakthrough of protozoan particles such as Cryptosporidium and Giardia. A pilot plant study utilising dual media filters was conducted to investigate a number of techniques for enhancing particle removal from settled water through filtration. These included use of filter aid polymer, increased coagulant dose and ozonation. While applying a filter aid polymer and/or increasing the coagulant dose was found to result in significant reductions in the residual particle counts, the most dramatic effect was achieved when the settled water was dosed with a combination of ozone and filter aid polymer. A paper by Yaode Yan.

Energy management “It is not about going to the gym”

Implementation of energy management is in many ways analogous to how people treat going to the gym. We know it’s good for us, we know we should be doing it and we all have the best intentions to do it. Getting started is the hardest part. Organisations behave like people when it comes to energy management. A paper by David Bowerman.

Swan hill wtp ‘poolifier’ – ozwater14

This paper details the application of water treatment design and operating principles in the design of temporary structures to enable coagulation, flocculation and settling in the swimming pool; describes the construction and commissioning of the equipment; details the operating performance achieved; and describes the challenges and obstacles faced and resolved in providing a temporary but robust and reliable process for clarification using a structure not intended for water treatment purposes. A paper by Dr Craig Jakubowski and David Girwood

Ozone and biological filtration for algal metabolite removal in australian waters

This presentation was delivered by Dr Craig Jakubowski and Dr Yaode Yan at OzWater 14 as part of Ozone day. The presentation outline is as follows:

  • Treatment methods for removing algal metabolites
  • Ozone and biological filtration for drinking water treatment in Australia
  • Pilot plant case study
  • Full-scale upgrade case study

The water and wastewater knowledge management system, developed by operators for operators

Paper based operations and maintenance manuals have been produced as the traditional method for delivering plant information. However they are often ‘left on the shelf’ and the original investment spent on these documents declines over time as the information becomes out of date.

This paper outlines how Hunter Water Australia (HWA) developed a knowledge management system (KMS), a ‘one stop shop’ where all aspects of plant operation are fully integrated and accessible in a timely manner. The benefits being how the KMS has improved training, operational consistency and has provided an extension of the quality management system to field operations.
