• Growing city with approximately 120,000 residents, located 100 km west of Toronto

• Sustainability is a guiding principle of our local growth management strategy

City of Guelph Background

Sustainability and GrowthIdentified as one of Ontario’s places to grow.

Challenges• Assimilative Capacity of Speed River for increased

Wastewater Effluent Loading

• Environmental and Fiscally Sustainable Water Supply

Solution• Guelph’s Local Growth Management Strategy

City of Guelph Strategic PlanGoal 6 - Leader in conservation and resource protection/enhancement

Objective 6.5 - Use less energy and water per capita than any comparable Canadian City

Water Supply Master Plan (2006)• 10% (5,300 m3/day) reduction in average day water use by 2010• 15% (7,950 m3/day) reduction in average day water use by

2017• 20% (10,600 m3/day) reduction in average day water use by

2025

City of Guelph Annual Water Production vs. Population Growth

• Approved by Guelph City Council in May 2009

• Multi-sector approach (Res/ICI/Dev/Municipal)

• 10-year, $20M strategy with goal of reducing average day water use by 8,773 m3/day by 2019

• Accounted for operational and GHG co-benefits

• Reclaimed water and wastewater capacity is estimated to defer need for $44 million in equivalent infrastructure costs.
