It required a whole of Australia response and was unprecedented, meaning we needed new ways of managing water. This study included desktop research, raw water characterisation and a pilot plant trial.Sydney Water developed a process model and advanced process optimisation to correlate raw water characteristics with filter performance and chemical dosing.At the same time Sydney Water, in partnership with SUEZ and Veolia, completed extensive pilot plant trials to identify the coagulation regime for raw water which is difficult-to-coagulate.Sydney Water completed catchment to customer (strategic) and operational system risk assessments to identify the bottlenecks at the WFPs production capacity, which helped to inform the planning studies.Engaging expert consultants in the water industry, Sydney Water completed a Process Capability Assessment (PCA) for each WFP. State governments undertook various projects to maintain supply to metropolitan areas, including the building of desalination plants. Dr Luke Mosley of the Environmental Protection Agency discusses water quality risks in the lower River Murray and lakes associated with the extreme drought.There are many signs of improvement, but we are just at the start of the journey to return the river to health and a sustained effort is needed to ensure we have a healthy, working river for the future.The Department for Environment and Water acknowledges Aboriginal

In Toowoomba, residents voted down a plan to add recycled sewage to the water supply.In 2018 much of Australia was again in drought but, while severe, it was not as prolonged as the millennium drought — the longest dry spell in post-colonial history, with nine consecutive years of low autumn rains, crucial for the southern cropping season.The book based on this timeline can be ordered through your bookstore or from the usual online stores. DOC fractions (Very Hydrophobic Acids (VHA), Slightly Hydrophobic Acids (SHA), Charged Hydrophilics (CHA) and Neutral Hydrophilics (NEU)), were correlated with water true colour and filter performances (Figure 5 and 6).Sydney Water, with catchment manager WaterNSW and research partner UNSW, were awarded an ARC Linkage grant in 2015 to better identify the raw water components impacting on floc strength and treatability, develop early warning monitoring systems for these components, and identify their sources.Sydney Water, in partnership with TRILITY Pty Ltd and NSW Public Works, completed a detailed study on treatability of high colour combined with low turbidity raw water at Macarthur and Nepean WFPs. Kangaroos invading Australian cities as drought worsens. 2010. Connell, D., and Grafton, R.Q. Data analysis of raw water from two sources, Nepean and Macarthur, showed that true colour increase in raw water following drought break rain is mainly due to the organic fractions (Table 1), and hence it is used as a surrogate parameter to reflect organic matter in water (Data analysis of true colour and VHA fraction of raw water, and Nepean WFP’s dual media filters run time and unit filter run volume (UFRV) found that, true colour of raw water is correlated with VHA fraction of DOC (Figure 6) and increase in VHA concentration or DOC caused decrease in filter performance by significantly reducing filter run time and UFRV (Figure 5).
The risk assessment identified short term improvement opportunities to reduce the treatment risk for high colour raw water. Mercer, D., Christesen, L., and Buxton, M. 2007.
