As part of its ongoing efforts to improve wastewater system management, SAUR recently used Pronal’s OTR inspection chamber test inflatable pipe plug. This project aimed to optimize leak testing operations on inspection wells, ensuring greater safety and operational efficiency.

Initial contact

SAUR, a key player in water management, needed to improve the watertightness of its inspection wells. Traditional methods were cumbersome, costly, and increased the risk of leaks. These constraints affected the reliability of the tests and compromised environmental safety.

Faced with this challenge, SAUR looked for a simpler and more effective solution. The company turned to Pronal, a specialist in sealing solutions, to find a high-performance alternative.

The Pronal solution, the OTR inflatable pipe plug

Pronal offered its OTR inflatable pipe plug, a sealing solution specifically designed to meet SAUR’s needs. This inflatable pipe plug, lightweight, and flexible plug integrates easily into sewer networks, allowing for quick and efficient leak tests. Made from high-quality materials, the OTR plug ensures optimal safety and enhanced durability.

Key results

The adoption of the OTR inflatable pipe plug transformed leak testing at SAUR. Thanks to its simplicity, technical teams quickly embraced it. One of the main benefits observed was a significant reduction in leakage risks, ensuring better network control. Processes were optimized, allowing tests to be carried out more quickly with fewer resources. Intervention safety also improved, reducing risks associated with handling heavy and complex equipment.
