Inspection
Sewers are prone to a wide number of constructional and operational problems including open and/or displaced joints, infiltration (the inflow of groundwater into the sewers), exfiltration (the outflow of sewerage into the ground), cracking, fracturing, deformation, collapse and more.
Detecting these deficiencies early allows owners to take steps to ensure further deterioration does not occur and also prevent dangerous fails like sinkholes, blockages and collapses.
CCTV Inspection
With CCTV inspection the process of identifying troublesome sewer conditions before they become problems is more efficient than ever.
Mar-Tech has a full complement of CCTV tools for pipe inspection.

Laser Profiling
The Laser Profiler is used in conjunction with our CCTV inspection system to project a ring of laser light on the interior of a pipeline. Analysis of the projected ring of light allows for measurement of defects, pipe size, lateral diameters, water levels and other features, as well as automatic and precise analysis of pipe ovality and capacity up to 30 times per second.
Deflection Testing
When new PVC, polyethylene, and fiberglass sewer pipes are installed, deflection testing is always part of the process.

Locating
Using a locator and sonde can accurately locate pipeline, manholes, and cables, as well as confirm line continuity and branches, and distinguish between target and other lines. The PDL2 locator used by Mar-Tech has a 512 MHz frequency, and provides fast, accurate depth measurement.
Smoke Testing
Smoke testing is a proven method of effectively identifying inflow (storm/ground water into sanitary sewers), connected roof and basement drains, yard drains, illegal taps, and storm sewer cross-connection. Reducing inflow and infiltration saves the costs of treating ground water at wastewater treatment plants.
The Environmental Protection Agency has advised municipalities to eliminate inflow and infiltration into sewer systems. Smoke testing sewer systems is an effective way to accomplish this goal.
