This paper provides an overview of some key observations from the research program into the quality of water supply from rainwater tanks conducted over the last decade. The research journey provides some key insights into water quality processes in rainwater tanks and highlights the need for continuing scientific endeavour to replace myths and agendas with facts about this important water source.
Dr Coombes has spent more than 30 years dedicated to the development of systems understanding of the urban, rural and natural water cycles with a view to finding optimum solutions for the sustainable use of ecosystem services, provision of infrastructure and urban planning.
Utilising mixed methods of defining joint probability of catchment and coastal flooding to increase certainty and utility of flood risk analysis Peter J Coombes and Robert Swan presenting at the Hydrology and Water Resources Symposium HWRS2024 on Tuesday 19 November...
New Journal paper from Peter J Coombes explores the influence of regulation, legislation and monopoly processes on preference for utility supply side infrastructure. The effects of price regulation and preference for utility supply infrastructure on Australian urban water utilities and urban water markets are considered by examination of historical data and models of the future of a case study of the Greater Sydney and Melbourne regions. Interesting read in the context of requests to double water bills and limit user pays pricing
The Essential Rainwater Harvesting Course was created by Peter Coombes of Urban Water Cycle Solutions (https://urbanwatercyclesolutions.com) and Michelle Avis of Verge Permaculture (https://vergepermaculture.ca). First recorded in 2020, a large majority of the course is now being released, for free, on YouTube as part of our shared mission to educate and spread information on rainwater harvesting as widely as possible.

Benefits, costs and enabling conditions to achieve ‘water for all’ in rural and remote Australia. I am honoured to announce the publication in Nature Water of our multidisciplinry research collaboration into an important challenge of access to good quality water in rural and remote communities.
Urban flood risks, water law and insurance: The intersection of emerging science, practice and authority By Professor Peter J Coombes Published in Precedent issue 178 - September/October 2023, Journal of the Australian Lawyers Alliance This article discusses the...
Results from two decades of accumulated big data and systems analysis of Greater Melbourne and Sydney was investigated to develop insights into the resilience of each city. The key resilience parameters are distributed water sources and conservation in an urban water market, household welfare, government policy and regulation, pricing strategies, total dam storage and supply of desalinated water. These parameters have different levels of impact and significance across the two cities. Further studies are needed to better define the attributes and benefits of these parameters.
