How to Integrate Sewer and Drainage Inspections into Your Asset Management Strategy

Effective asset management is crucial for municipalities and utility providers to ensure the long-term sustainability and functionality of their sewer and drainage systems. Integrating inspections into your overall asset management strategy is essential for identifying potential risks, preventing costly failures, and extending the life of your infrastructure. In this post, we’ll guide you through the steps of incorporating sewer and drainage inspections into your asset management approach to maximize system performance, including:

• Assessing your current inspection practices
• Leveraging technology for more efficient inspections
• Creating a risk-based inspection schedule
• Integrating inspection data with asset management software

Assess Your Current Inspection Practices

Before integrating inspections into your asset management strategy, it's important to evaluate your existing inspection practices. Understanding how frequently inspections are conducted, the methods used, and the data collected will allow you to identify areas that need improvement.

Proposed Steps in Assessment:

• Review inspection frequency and consistency – Identify how often your inspections are performed and whether they cover all critical areas of the sewer and drainage system. Regular, consistent inspections ensure that no assets are overlooked.
• Evaluate the quality of data collected during inspections – Determine if your current data collection methods capture all relevant information about the condition of your assets, such as pipe deterioration, blockages, or collapses.
• Identify gaps in current inspection practices – Look for areas in your system that might not be getting enough detail or attention, such as infrequently inspected segments of the catchment or assets that are harder to access.
• Determine how well inspection results are being integrated into decision-making processes – Ensure that the data collected from inspections is used effectively to inform maintenance schedules, repair priorities, and capital investments.

By assessing your current practices, you can set a baseline for future improvements and align inspections with your organisations asset management goals.  

A sample case study is with Greater Western Water & VAPAR: Greater Western Water in Australia faced challenges with inspection data and insights into their sewer network condition. Greater Western Water utilised VAPAR.Solutions to assess nearly 40 km of inspection footage using AI. This automated process provided more accurate, standardised condition data, helping Greater Western Water identify gaps in their current inspection practices. By integrating this data, they were able to rationalize almost $2M in capital works estimates and improved their decision-making for maintenance and repair priorities. 

Leverage Technology for More Efficient Inspections

Technology plays a significant role in streamlining sewer and drainage inspections. By integrating tools such as CCTV (Closed Circuit Television) cameras, sensors, and AI-powered platforms, you can gather accurate data faster and more efficiently.

Technologies to Consider:

• CCTV Cameras – These cameras are inserted into sewer lines and provide real-time footage of underground infrastructure. They can detect issues like blockages, cracks, and leaks that may not be visible from the surface, enabling more accurate diagnostics.
• Robotics – Drones and robotic crawlers can navigate areas that are difficult or unsafe for human inspectors to reach. They provide high-resolution imagery and data without the need for extensive labor, making inspections safer and more efficient.
• AI and Machine Learning – AI-powered software can automatically analyze inspection data, identifying trends and potential risks. This reduces human error and speeds up the inspection process by highlighting areas that need immediate attention.

Incorporating these technologies not only improves inspection accuracy but also reduces time and labor costs, making your asset management strategy more cost-effective.

The case of Townsville City Council using VAPAR’s platform is a great example. Townsville Council needed a faster, more efficient way to assess the condition of their 1,200 km wastewater network. By leveraging VAPAR’s AI-powered platform, they were able to quickly process and analyze CCTV footage, identifying over 9,500 pipe defects and prioritizing assets in need of urgent repair.

In just 8 weeks, Townsville identified over 20 high-risk assets requiring immediate attention, enabling them to develop a detailed rehabilitation plan, thereby reducing time and labor costs for future inspections  

This shows how integrating advanced technologies like AI and CCTV cameras can streamline the entire inspection process, making it more accurate and cost-effective.

Create a Risk-Based Inspection Schedule

Not all sewer and drainage assets require the same level of inspection frequency. By prioritizing high-risk areas and assets that are more prone to failure, you can allocate resources more effectively and focus on the sections of your system that need the most attention.

Steps to Develop a Risk-Based Schedule:

• Identify high-risk areas based on historical data – Use past inspection records and failure history to pinpoint areas that have a higher likelihood of problems, such as locations with frequent blockages, cracks, or previous repairs.
• Use inspection data to determine which assets are most vulnerable – Analyze collected data to assess which parts of your system are aging or degrading more rapidly. These assets should be inspected more often to prevent major failures.
• Create a tiered inspection schedule – Establish different levels of inspection frequency, with high-risk areas receiving more frequent checks, while lower-risk sections are inspected less often. This ensures that resources are used where they are most needed.
• Adjust your schedule based on new data – As new data is gathered through inspections, adjust the schedule to keep it current. This flexibility ensures your approach remains proactive and responsive to real-world conditions.

A risk-based approach ensures that critical assets are always prioritised, reducing the likelihood of unexpected failures.

Integrate Inspection Data with Asset Management Software

One of the most effective ways to integrate inspections into your asset management strategy is by using specialized asset management software. These platforms allow you to collect, store, and analyze inspection data, ensuring it is accessible to decision-makers and teams responsible for maintenance.

Benefits of Asset Management Software:

• Centralizes all inspection data for easy access – Asset management software provides a single platform where all inspection reports, videos, and sensor data are stored. This eliminates the need to search multiple sources and ensures everyone is working with the same information.
• Automates reporting and tracking of maintenance activities – The software can automatically generate reports, track when inspections were last conducted, and alert you when maintenance is due. This helps keep the system running smoothly without missing important maintenance windows.
• Provides insights and trends that can improve long-term asset planning – Over time, the software can analyze trends in asset performance and deterioration, offering data-driven insights that inform your long-term capital planning and budgeting.

By centralising your data, you can ensure that every inspection contributes to a clearer understanding of your system’s condition, guiding maintenance and capital investment decisions.  

A perfect sample of this is how VAPAR has partnered with platforms like Info360 Asset to streamline this process. Their platform allows data collected from CCTV inspections to be fed directly into asset management software. This integration centralizes all inspection data—videos, reports, and metadata—into one platform, ensuring that teams have easy access to accurate and up-to-date information.

This integration helps asset owners make informed decisions, prioritize repairs, and optimize budget allocation by providing a clearer view of their sewer and drainage networks. For more details on how VAPAR integrates with platforms like Info360, you can check out their information here.
