Course Catalogue.

After participating in the course, you will be able to:
• Analyze CSO loads and impacts to better understand how your combined sewer system operates,
   and decide how best to control your CSOs
• Benefit from the experiences of other communities with problems similar to your own
• Increase familiarity with sewer hydraulic models to choose the best model for your system
• Apply the practical knowledge of current state of the art CSO technologies to help design CSO control
   measures and prepare design contracts
• Predict the impact of current and contemplated guidelines and objectives for CSO control on your organization
• Make informed decisions on management and control of your CSOs

Description
Recent changes in the objectives and guidelines for combined sewer overflow (CSO) control, and new approaches to CSO control, make it necessary for individuals responsible for managing and reducing CSOs to learn more about the state-of-the-art in CSO control, including current approaches and technologies, and future trends. This two-day forum is designed to provide you with all of the tools necessary to manage CSOs, including advice on planning, data collection, predictive sewer modeling, proven and emerging technologies, design procedures, operations and maintenance considerations, and contemplated changes to guidelines and objectives. Participating in this forum will improve the quality of your decisions relating to CSO control and bring long term benefits to your organization.

Objective
To familiarize you with proven and practical methods of CSO control, and the latest technological trends to meet new CSO guideline objectives.

Who Should Attend
Municipal engineers, project managers/engineers/technicians for waste water collection and management, water resource engineers, consulting engineers, designers, regulators, environmental services engineers, conservation authority engineers, and other technical persons with responsibility for managing, operating and maintaining combined sewer systems in regional municipalities.

Instructor: Mark Stirrup, Principal Project Manager, Hatch Mott MacDonald
