The Future of Australian Housing Design
Responding to population growth and climate change
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.

Market Mechanisms for Better Stormwater Management

Market Mechanisms for Better Stormwater Management

Peer reviewed publication and presentation by Dr Peter Coombes at Stormwater 2018 conference. Changing the way we think about stormwater management – linking impervious areas to stormwater tariffs. “However, consider the extra motivation this would provide – if we knew we were paying for concrete  – there’d be a real economic benefit to reducing impervious areas and increasing gardens and rainwater harvesting with all the obvious benefits. This is a real shift in our thinking”

This research project builds on previous publications by the author that utilised a Systems Framework of historical big data from government agencies and utilities to identify the water and stormwater benefits of property scale water conservation measures for Australian cities. Bottom up systems analysis is used  quantify the stormwater resources and economic value of  stormwater infrastructure for Greater Melbourne.
