York Region Developer-Led Inflow and Infiltration (I/I) Reduction Program

In urban planning and infrastructure, water management plays a pivotal role in ensuring sustainable development. Municipalities and land developers constantly seek innovative solutions to manage wastewater efficiently while minimizing the environmental impact.

In this context, York Region’s Developer-Led Inflow and Infiltration (I/I) Reduction Program emerges as a groundbreaking initiative that addresses these challenges head-on. This case study explores how the program revolutionized sewage water management through advanced techniques and collaboration.

Project Description

York Region partnered with Civica Infrastructure Inc. to tackle the pressing issue of inflow and infiltration in the sewage system. Inflow and infiltration refer to unwanted water entering the sewer system, causing inefficiencies and potential overflows. By addressing these issues, the York Region aimed to enhance its sewage water management capabilities.

Our team embarked on a comprehensive mission, employing a range of innovative techniques. Extensive flow monitoring through a network of over 120 flow monitoring stations and 50 rain gauges allowed for accurate data collection. This data-driven approach laid the foundation allowing us to develop new sanitary flow models and optimize I/I reduction measures.

The program introduced pioneering methods such as standard, wet, and dry CCTV sewer inspections, along with smoke and dye testing. These techniques enabled us to perform a thorough inflow and infiltration inspection, identifying problem areas and informing targeted remediation efforts. The project also involved extensive stakeholder communication, including engaging with local municipalities and residents, ensuring seamless collaboration throughout the process.

Relevance of Experience

York Region’s I/I Reduction Program showcases the importance of environmental monitoring and data analysis in achieving effective wastewater monitoring. By integrating cutting-edge tools and methodologies, such as storm sewer and sanitary sewer capacity analysis, the program set new standards for inflow and infiltration reduction.

Our expertise in mapping, reporting, and risk assessment contributed significantly to the program’s success. The approach included defect remediation analysis and cost-benefit assessments, ensuring optimal resource allocation. The project exemplified the critical role of resident engagement and communication in achieving successful outcomes, highlighting the need for a robust stakeholder communication plan.

Lessons Learned

The York Region project provided us with invaluable insights into the intricacies of inflow and infiltration reduction:

• Active and consistent communication with stakeholders was crucial, as engaging regional authorities, local municipalities, and residents fostered collaboration.
• Stakeholder signoffs at multiple checkpoints were vital for success, facilitating effective remediation works and minimizing disruptions.
• Offering a warranty period on private property works boosted stakeholder satisfaction and trust.
• The program highlighted the need for municipal incentives to promote innovative techniques:
  • Incentives for testing new products and methods can drive future I/I reduction efforts.
  • Encourages continuous improvement in water management practices.
