What should a record log of hydraulic cleaning operations include?

A comprehensive record log of hydraulic cleaning operations is essential for tracking the effectiveness and efficiency of cleaning activities within the sewage system. It should include detailed information on the type and amount of material removed from downstream manholes. This data is critical for assessing the performance of the hydraulic cleaning and for planning future maintenance activities. Monitoring the type and volume of debris collected can help identify problem areas within the system, informing any necessary preventative measures or improvements to cleaning techniques.

While other details such as the amount of rod or cable used and equipment malfunctions may be relevant to operational performance, they do not provide the same level of insight into the system's condition and the success of the cleaning operation. Therefore, focusing on the specifics of what was removed is essential for maintaining the integrity of the collections system and ensuring its long-term efficiency.
