A 'Grand' challenge

Feature 1 art

Significant population growth in southern Ontario is a major challenge for the future of the Grand River. Most cities located in this watershed rely on the river or wells for their water supplies, and discharge their treated wastewater into the river or its tributaries. Long-term planning in combination with an effective water quality monitoring and assessment program can help predict changes to the river. Targeted monitoring also will provide essential information to optimize the wastewater treatment plants that discharge to the Grand, with the ultimate objective of improving water quality in the river.

 

Resurfacing a reputation

Feature 4 art

For many years, the City of Indianapolis Department of Public Works (DPW) has been finding great value in shotcrete to preserve its large-diameter sewer pipe, especially interceptors. The city has embraced the use of shotcrete for large-diameter sewer rehabilitation projects, and the costs just keep getting lower.

Firm footing

Organizations that are accustomed to measuring and reporting their sustainable practices might soon be adding another calculation to the mix: water footprinting.

A water footprint is a measurement of how much water is used — directly and indirectly — by an individual, a community, or a business.

Virginia prevails at Operations Challenge 2010

Congratulations to Division 1 champions Terminal Velocity and Division 2 champions Team HRSD, both from the Virginia Water Environment Association. Thirty-seven teams competed in New Orleans at the 23rd annual Operations Challenge to see who came out tops in Process Control, Laboratory, Wilo Maintenance, Collection Systems, and Safety events.

Check out the December issue for complete coverage, including a list of all overall and event winners, photos of the competition, and interviews with the competitors.

 

Warming up to new ideas

Energy reduction and conservation are staples of wastewater treatment operations and design. Every treatment plant tries (or should try) to get the most treatment bang for its energy buck. But to take the next step and begin producing energy for plant use takes a shift in perspective.

Read about a strategy that can help plants navigate the path toward reaching the break-even point between energy production and use. Even if the changes you can make fall short of the ultimate goal of an energy self-sufficient plant — at least one plant worldwide has accomplished this — the improvements and innovation made along the way can help to lower energy costs and improve treatment capacity.

Another article considers how to mine heat directly from wastewater. The False Creek Energy Centre in Vancouver, British Columbia, generates about 70% of the total thermal energy demand of its neighborhood. What’s unique is that most of this energy was extracted from the wastewater flowing underneath the neighborhood’s streets.
