Urban Growth & Sustainability:Implementation challenges & opportunities
The Story in Guelph
Overview of presentation
1. Growth in the Greater Golden Horseshoe
2. Key policy directions
3. Challenges to going further
Growth in the Greater Golden Horseshoe
Growing mid-sized city 100 km west of Toronto
124,000 today; 175,000 in 2031
Sustainability is a key principle of our local growth strategy
• Fastest growing urban area in Canada
• Third fastest growing urban area in North America
• Grow by over 4 million people by 2031
• 1.7 million new households
• 45% longer commuting times
• 42% increase in auto emissions
• More than 1,000 square kilometres of farmland consumed
By 2031 in Guelph
• 54,000 new residents • 31,000 new jobs
Key policy direction
40% of new growth in the built boundary i.e. not green field

Substantial change in the form of growth
From the fringes to the urban growth centre, nodes & corridors
Goals of “Places to Grow” are addressing many global challenges
• Revitalize downtowns • Create complete communities • Provide housing options• Curb sprawl• Protect farmland & green spaces• Reduce traffic gridlock – greater range of
transportation options
Policy Directions in Water, Wastewater, Waste,
Energy, & Biodiversity
• Water Management Master Plan approved
Key policy direction:
Sustainable use of local resources
i.e. no pipeline to Lake Erie
Protection of local resources

• Water Conservation & Efficiency Strategy (being updated)
• Toilet rebate• Clothes washer rebate • Industrial, commercial and institutional
buy backs• Landscape assessment program • Outdoor water use by-law

• Residential Grey Water Reuse Pilot
• Water conservation co-benefits study – energy and GHG co-benefits
• Industrial Benchmarking Exercise – UG/Province– Guelph is a participating municipality
First LEED Platinum Home in Canada Reid’s Heritage Homes
Rainwater harvesting system
Rainwater collected, filtered and stored in a cistern
Supply 3 toilets, washing machine, dishwasher and outdoor irrigation
50% of water consumption in a typical home
• Wastewater Management Master Plan underway
Key policy direction:
Sustainable use of local resources i.e. the river
i.e. no pipeline
Re-use (re-branding)
• Effluent reuse
• Use of biosolids
• Heat recovery
• Optimizationpeople & facility focused

Capital savings in Wastewater
Global challenge – water quality vs cost ($)
• Reduced need for another anaerobic digester – $5 million
• Elimination of the need for a UV system – $ 8 million
• Deferral of Stage 2 expansion for 10 years– $20 million
• Lystek technology• High quality product
• Land application (fertilizer)
• $1.2 million in avoided annual landfill costs
• Reduced carbon footprint
• Increased green power production
• Energy conservation
Advanced Biosolids Treatment
• Waste Management Master Plan approved
Key policy direction: Zero Waste Philosophy
• Waste minimization (corporate leadership)• Waste diversion from landfill
– recycling, reuse, organics – 55% by 2011 65% by 2016 70% by 2021
• Community Energy Plan approved
Key policy direction:Energy use per capita & resulting GHG emissions will be less than the current global average

Increase in population of 54,000
Net reduction in energy consumption (50% less)
Reduction in GHG from 16 to 7.0 tonnes (60% less)
Setting priority to the CEP recommendations
1. Energy efficiency If you don’t need it, don’t use it
2. Heat Recovery If it’s already there, use it
3. Renewable energy If it makes sense, go carbon free
4. Regional & local Invest where it makes utilities sense to avoid duplication
