Sewer Line Testing

Sanitary Sewer Acceptance Testing:  Sanitary pipelines ranging from 4″ to 72″ are tested as a whole pipe by plugging each pipeline end, pressurizing the space and measuring any air loss.  Joint testing may be utilized in larger diameter pipe.

Storm Sewer Acceptance Testing:  Storm pipelines ranging from 4″ to 72″ are joint tested by placing a circular steel supported bladder at each joint and testing each joint separately.  Fiber glass reinforced polymer mortar pipe may be tested by joint testing or as a whole pipe.

Leak Locating:  Leak location is actually a series of small line acceptance tests. Two inflatable balls are connected and pulled through the pipe 25 feet at a time to find a leak. An air test is run each time the balls are stopped. When a section fails, the contractor is notified so that they can either check the services at the point of failure or dig up the line to find where the leak is occurring.
