Optimized Water Resources Management Using the IWRET Tool

Showcasing a new tool for optimal water management strategies

In October 2018, Urban Water TMU officially launched the Integrated Water Evaluation Tool (IWRET)!

The IWRET is an online tool that is freely accessible! The tool is meant to assist decision makers in selecting the optimal water management system on a precinct by precinct basis.

The IWRET Tool takes into account the networks of buildings, their intended usage, and associated infrastructure in each neighbourhood to predict water/energy balances and nutrient recovery for various scenarios (including climate change and population growth). The tool provides decision makers with output parameters in order to enable reduction in wastewater generation, potable demand, energy consumption, and other evaluation criteria (both quantitative and qualitative).

The IWRET Tool is the product of a multi-year research project led by Urban Water TMU researchers Darko Joksimovic and Vladimir Nikolic and Waterfront Toronto’s Aaron Barter supported by a grant from the Federation of Canadian Municipalities. The City of Toronto, the Toronto and Region Conservation Authority, and the Ministry of Environment and Climate Change were partners on this grant and formed a steering committee to guide its development.

Additionally, Urban Water TMU hosted two consultations with municipal water managers, developers, conservation authorities, and consultant engineers to incorporate their insights and feedback into the tool.
