Laterals, pipe inspection/repair

The ES-38 is designed for scanning laterals from 3 to 8 inches in diameter. Using Electro Scan’s proprietary technology, variations of electricity flowing through the pipe wall, associated with distance measurements, are automatically transmitted to Electro Scan’s Smartphone application to record and display defect locations and their relative size. While electricity does not pass through non-metallic pipe walls, it will pass through any defect that can cause water leaks.

Rehabilitation of failing sanitary sewer systems is a high priority for many cities in the United States with major projects under way relining and replacing aging and failing mains.

Failing sanitary sewer systems are confronting American cities of all sizes. Many systems are operating beyond capacity and old underground infrastructure is crumbling with infiltration causing overflows following heavy rains and leaking sewage contaminating groundwater. Many systems are operating under U.S. Environmental Protection Agency consent decrees in which customers ultimately pay for correcting serious deficiencies.

A new self-propelled, all-in-one robotic crawler/cutter/video system for reinstating laterals in newly lined sewer mains has been introduced to the North American market by Cosmic Top Hat, LLC.

Considering the state of the economy, results from Underground Construction’s 12th Annual Municipal Survey reflected surprising optimism among city personnel across the United States. Understandably nervous and cautious about 2009, municipal personnel expect their funding levels to decline somewhat, though still remain near 2008 levels.
