For many years various methods have been available to treat sewer infiltration and inflow (I/I) disease. However, because of ineffective diagnoses, expensive treatment of part of the system has often failed to provide relief, and sewer
I and I remains chronic.
What You Can't See Can Hurt You!
Like humans, utilities rely on their circulation system. Maintaining that system means discovering small defects before they become large ones, and finding large ones before they become gross failures.
CCTV misses any defect without clear visible evidence. Because of the way joints, service connections and manhole connections are constructed, CCTV can't see most of the defects. It also can't see leaks that only occur during rainstorms when the pipes are full. CCTV inspection is a time-intensive process that relies on the potentially fallible judgment of field operators and video interpreters. Incomplete or unreliable data often result in inappropriate, ineffective and expensive rehab with no guarantee of success. Diagnosing pipes with CCTV is like relying on a cardiologist without an electrocardiograph. What this patient needs is a better instrument that leaves nothing to the imagination.
With so many miles of pipe to diagnose and treat, early detection and rehab prioritization are critical capabilities. Which begs the question: Why do so many municipalities still heavily rely on CCTV for diagnosis?
If You've Got The Money, Honey, I've Got The Time!
Sewer flow monitoring will quantify I/I. However, it is like knowing a patient has a fever - There is something wrong, but where? And the results of flow monitoring take several months, or years to fully develop in order to reach any conclusion. Consequently, although Billions have been spent on flow monitors, I/I has a source, and locating it has largely fallen to the lot of CCTV inspection and smoke testing. This is a little like restricting a doctor to only using a stethoscope for disease diagnosis. It is very a effective method for some diseases but not all. A targeted diagnostic tool, the equivalence of blood tests and microscopes in medicine, is required to provide the critical information of where the pipes defects are, before the I/I disease can be treated cost effectively.
Hope is abundant, but money isn't; And there are several infrastructure issues we need to address in this Country.
