1. Data Gathering: The assessment begins with a comprehensive inventory of the storm sewer network, including the location of inlets, manholes, and pipe segments. Zoom cameras are used to inspect surface-level features, such as manhole covers and inlet conditions.

2. Remote Inspection: Zoom cameras are the primary tool for remote inspection. These cameras are used to visually assess the condition of above and below ground storm sewer infrastructure, identifying issues like cracks, corrosion, blockages, and structural damage.

3. CCTV Camera Utilization: In some cases, where access is difficult due to depth or obstructions, CCTV cameras will be deployed. These specialized cameras are inserted into the sewer pipes to provide a detailed visual inspection of the underground system. They capture footage to assess pipe integrity, identify obstructions, and detect signs of wear and tear.

4. Data Analysis: The data collected from both the zoom cameras and CCTV cameras are analyzed to create a comprehensive report. The analysis includes identifying structural defects, noting the presence of debris or sediment in the pipes, and assessing the overall condition of the storm sewer system.

5. Defect Classification: Defects and issues were categorized based on their severity and urgency for repair or maintenance. This classification helps prioritize necessary actions and budget allocation.

6. Recommendations: The assessment generates a set of recommendations for repairs, maintenance, and rehabilitation of the storm sewer system. These recommendations are based on the findings and the assessed condition of the infrastructure.

7. Asset Management: The inventory data is then integrated into an asset management system to monitor and track the condition of the storm sewer system over time. This allows for proactive maintenance and long-term planning.

The information and data gathered within the project is invaluable for public works staff, and maintenance crews to assist in making informed decisions about necessary repairs, upgrades, and preventive maintenance measures to mitigate future problems.

In summary, the Storm Sewer Inventory Cleaning and Conditions Assessment project includes an effective evaluation of the storm sewer system. The methodology ensures the continued functionality of the storm sewer networks, reduces the risks of flooding, and enhances the overall efficiency of the urban drainage system.

Background:

The City of Port Colborne prioritizes storm sewer inventory, cleaning, and condition assessments to help prevent flooding, protect the environment, maintain infrastructure, comply with regulations, and ensure public safety and satisfaction. These activities contribute to the resilience, sustainability, and well-being of the community and its natural surroundings.
