Preserving Potable Water: A Case of Steel Pipe Repair in a Service Reservoir
Water is one of the most vital resources for life, and in the United States, it's processed through thousands of treatment plants before reaching our homes. Once treated, water flows through a complex network of pipes and storage facilities, including service reservoirs. These reservoirs play a crucial role in maintaining steady water pressure and supply, especially in areas with varying elevations. While some are visible as elevated towers, others, particularly in hilly or mountainous regions, are built underground.
Over time, exposure to moisture and oxygen can cause corrosion in the steel pipes and tanks within these reservoirs. This not only leads to leaks but also poses a risk of contaminating the clean, potable water supply. In one such case, an underground service reservoir in the southwestern U.S. faced urgent repair needs due to pitting and leaking in three outlet pipes. About 5% of the piping showed signs of corrosion, with some sections deteriorating along the edges of the concrete tank.
The project required a solution that met NSF-61 standards to ensure the safety of the drinking water. Additionally, the reservoir could only be taken offline for a short period, creating a tight schedule for the repairs. HJ3’s CarbonSeal Steel Pipe Repair System was chosen for its compliance with ANSI/NSF 61 and its proven effectiveness in restoring structural integrity quickly.
The process began with surface preparation using abrasive blasting with NSF-61 approved media. The affected pipes were then patched, primed, wrapped with carbon fiber, and finished with a chemical-resistant topcoat. The entire repair was completed in a single day, meeting the strict timeline while ensuring long-term durability and safety.
HJ3’s CarbonSeal system not only met all regulatory requirements but also restored the pipes to their original strength. This successful repair highlights the importance of timely maintenance and the use of advanced materials in preserving critical water infrastructure.
