SYSTEMS PERSPECTIVE ON CHARACTERISING RESILIENCE IN URBAN WATER MARKETS

SYSTEMS PERSPECTIVE ON CHARACTERISING RESILIENCE IN URBAN WATER MARKETS

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.

Review of the Hill End Water and Sewerage Scheme

Review of the Hill End Water and Sewerage Scheme

The township of Hill End was established during the 1880s due to the discovery of gold in the area and in 1967 part of the town known as the historical village of Hill End was proclaimed as a historical site. Hillend is located about 70 km northwest of Bathurst and 69 km south of Mudgee.

Rainwater harvesting and systems thinking for a better world – release of YouTube Channel

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.

Dr Peter Coombes is speaking on the economic advantages of decentralised water and stormwater management at the Rainwater Harvesting breakfast at 7:30 am on Wednesday 27 February 2019 at the Parramatta Novotel.

Tone Wheeler, Principal of Environa Architects will be discussing how architects are, and believe we should be, responding to these challenges. 

Lord Mayor Andrew Wilson will be speaking on the Parramatta Environmental Sustainability Strategy 2017

Australia city face escalating challenges of population growth, economic development, decline of ecosystems and climate change. A number of new urban housing challenges have emerged, and western Sydney is experiencing all of them.

Systems Analysis of Water and Sewage Services, Costs and Prices

Systems Analysis of Water and Sewage Services, Costs and Prices

Bottom up systems analysis of urban water resources and market mechanisms for pricing water and sewage services
Presentation Peter J Coombes, Michael Barry and Michael Smit at the HWRS 2018 conference in Melbourne at 11:00 am on Tuesday 3 December 2018. Consumers in the Greater Melbourne region pay uniform fixed and variable tariffs for utility water and sewage services. Removing fixed tariffs creates substantial reductions in water demands and improvements in water security to 2050 at a net present value of $8.6 billion. A full usage tariff regime was seen to increase water efficient behaviours and reveals improvements in household welfare.
