Optimising Environmental Compliance and Safety with Advanced Drainage Flow Monitoring

By monitoring parameters such as flow, depth, velocity, and water quality, rail operators can prevent infrastructure failures, avoid service disruptions, and ensure compliance with trade effluent consents.

The Importance of Drainage Flow Monitoring

Drainage systems play a vital role in supporting railway infrastructure. Blockages, overflows, or structural damage within these systems can have significant consequences, including the destabilisation of railway tracks.  Such issues can lead to serious incidents like train derailments, which pose a threat to both public safety and the continuity of rail services. Regular drainage flow monitoring helps detect these problems early, allowing for timely interventions that prevent costly and potentially dangerous outcomes.

By measuring key parameters—such as rainfall, flow, and depth—monitoring systems provide valuable data that can be used to assess the condition of drainage networks. This data enables rail operators to identify anomalies, such as unexpected changes in flow rates or water levels, which may indicate blockages, leaks, or structural weaknesses. Addressing these issues before they escalate is essential for maintaining the integrity of railway infrastructure.

Consents to discharge trade effluent issued by the water utility companies also specify non-quality related conditions such a daily maximum permitted discharge volume and hourly permitted discharge flow rates.  Such parameters are important to prevent overloading the local sewer system or preventing surcharging during times of peak flow.

These parameters are affected by day to day depot operations such as vehicle servicing & maintenance, train cleaning either using automated carriage washing plants or within the shed by hand (Hand Bashing), pit cleaning or as is more common these days, due to environmental conditions such as increased rainfall.      

Monitoring discharge volumes and flow rates ensures compliance with consent conditions and highlights situations where a revision to the consented volumes may be required due to changes in depot operations or local conditions.

Enhancing Maintenance through Predictive Monitoring

Predictive maintenance is an essential strategy for ensuring the long-term reliability of railway operations. Drainage flow monitoring forms a critical component of this approach by providing continuous insights into the health of the underlying infrastructure. By tracking changes in water quality and flow over time, rail operators can anticipate potential issues and schedule maintenance activities more effectively.

For example, a sudden increase in water levels or a change in velocity may signal a developing blockage or structural issue within the drainage system. Early detection through monitoring allows for targeted maintenance interventions, reducing the likelihood of unexpected disruptions and minimising the costs associated with emergency repairs.

Component-Specific Monitoring and Analysis

Different components of the drainage system require tailored monitoring approaches. For example, Combined Sewer Overflows (CSOs) located near railway tracks might need more frequent monitoring due to their potential to overflow during heavy rainfall, posing a direct threat to the rail infrastructure. Monitoring the performance of these components through flow meters and water quality sensors helps ensure that they are functioning correctly and that any issues are identified and addressed promptly.
