Sewer contractors are the backbone for helping muncipal utilities to make emergency repairs, bid on complex rehabilitation and re-ling projects, and work with outside engineering firms to deliver Sanitary Sewer Evaluation Studies (SSES).
Time is money for sewer contractors, especially if a customer is unhappy with work performed. In the past, contractors or public agency personnel might CCTV a newly renovated pipe as part of their acceptance of a project. Today, more utilities, aware of more stingent requirements to prevent sanitary sewer overflows, are taking a closer look at completed rehab jobs, to ensure recommended repairs are delivering the promised results.
Electro Scan is now becoming the #1 choice of progressive sewer utilities to verify and validate repairs on both sewer laterals and sewer mains. By thoroughly scanning the inside of sewer mains, electro scan is one of the few detection devices that can verify that re-attached service connections in pipe lining projects have no evidence of leakage.
So, why not ensure your project is ‘water tight’ before you leave the job site?

Sewer Relining Companies
Whether first idenfying defects sufficient to warrant reling or as part of your post-rehabiliation certification processes, Electro Scan is the only vendor capable of ensuring that a relining project has achieved the proper seals and elimination of leak potential.
Gone are the days of when outside contractors would be required to run a CCTV camera down a newly relined sewer main and simply give a copy of the video to confirm that all the leaks have been fixed. More and more sewer utilities are finding out that relining projects completed just a few years ago, have even more leaks than before. You can’t see what’s behind the pipe and Electro Scan is the only vendor that can certify your relining project.
Chemical Grout Service Companies
Service companies that specialize in applying chemical grout understand that joints or other defects are not necessarily fixed simply by seeing an internal grout ring. The only way to ensure a seal is by placing the correct amount of grout outside the joint — an area that cannot be seen by visual observation. As a result, it is important, either for service companies to certify their work or to have the municipal sewer utility certify the contractor’s work.
The only solution capable of certifying that chemical grout has been applied correctly, is by using electro scan! So why not verify your work after grouting, with Electro Scan?
