City of Edmonton - Kennedale Storm Basin
The Kennedale storm basin covers a significant portion of Edmonton’s storm system and as a result, even relatively small storm events deliver high volumes of runoff and pollutants. To mitigate the effect of these pollutants, the City of Edmonton has constructed an artificial wetland capable of treating various pollutants found in stormwater. Previously, all of Edmonton’s stormwater management facilities had been built primarily for flood prevention.

City of Ottawa - Quantitative Microbial Risk Assessment
The City of Ottawa has been a leader in the application of QMRA for optimizing drinking water treatment and enhancing water safety. QMRA (Quantitative Microbial Risk Assessment) is a newly developed tool that evaluates the microbial risk in an individual water system in terms of annual risk of illness for the population.

City of Ottawa -
Woodroffe Acoustic Fiber Installation
On January 14, 2011, Ottawa experienced a massive watermain failure impacting approximately 80,000 residents. This was the second recorded failure along that line but this failure was approximately 500 m north.
The ultimate renewal strategy included replacing 1 km of main (incorporated the most deteriorated sections), the installation of Acoustic Fiber Optic (AFO) Cable (PURE Technologies) and transient monitoring along the single feed length (5.1 km).

Halifax Water - Central DMA/PMA: Flow Modulated Pressure Control
Halifax Water adopted the AWWA/IWA Water Loss Methodology in 2000. Since that time, Halifax Water has reduced its Infrastructure Leakage Index (ILI) from 9.0 to 3.0, resulting in a reduction in system inputs from168 to 130 million litres per day.

Metro Vancouver - Co-Digestion Pilot Project
The Annacis Island Wastewater Treatment Plant (WWTP) is the largest secondary treatment plant in British Columbia and serves a population of more than 1 million residents. A $2.6 million co-digestion full-scale pilot project has been built at this plant to enable the direct feed of high-strength organic wastes along with sludge, settled from sewage treatment facilities, into the existing anaerobic digesters to generate biogas and increase energy production at the WWTP. The project was completed in April 2011 and is now fully operational.

Ontario Clean Water Agency - New Technology to Boost Energy Efficiency
In early 2011, the Ontario Clean Water Agency (OCWA) saw an opportunity to make a difference in a Northern Ontario community. The OCWA-operated wastewater treatment plant in the Township of Black River-Matheson was facing some challenges. It was not working at its maximum capacity – operating at higher than normal costs and the oxygen transfer efficiency of the installed course bubble aeration system was relatively low.
With the aeration system upgrade, Black River-Matheson was able to convert the wastewater treatment plant into an energy-efficient one.

Regional Municipality of Durham - Polybutylene Water Service main stop locates using a CCTV Camera
In 2009, the Region of Durham received $9,980,000 from the Infrastructure Stimulus Fund (ISF) for the replacement of 2,000 polybutylene connections. In order to comply with the funding time constraints, a faster method to find these main stops was needed.
The Region of Durham currently examines sanitary sewers and sewer laterals, and inspects water reservoirs with CCTV cameras, which sparked the interest in examining a watermain with the same technology

Windsor Utilities Commission - SCADA Innovation
The Windsor Water Treatment Complex is one of the most technologically advanced in Canada, thanks to recent innovative Supervisory Control and Data Acquisition (SCADA) and wireless technology investments.
The current SCADA infrastructure (similar to most SCADA architecture installations in various industries) was at the end of its useful life and vulnerable to single points of failure. For example, if the system and had lost an input/output (I/O), such as the one running the chlorine dosing pumps, the SCADA system would fail to meet the regulatory requirement and result in an adverse water quality incident.
