Before fresh water can be made safe for human consumption it must go through a treatment process eliminating bacteria and any other elements deemed unsafe to drink. How does such a process occur and why is it relevant to us? We’ve written about the use of Deep Trekker remotely operated vehicles and pipe crawler systems in storm water systems, sanitation pipes, and water storage basins. A ...

When your inspection task is to survey a critical pipeline for leaks, nothing is more satisfying than trusting your technology to predict the leak location and then standing by as the client excavates the area to find a flow of water within one meter of exactly where you said it would be. The above-described "leak-where-predicted" recently happened with the City of ...

Every water system typically consists of piping networks that distribute water from a source or storage reservoir to the end users. This frequently requires miles of piping mains along with pumps systems and controls that all have to be monitored and controlled somehow. Whether this control is to regulate pressure, a level or a flow, this usually will require some form of a ...

Increasing pressure loss in the pipeline is often caused by scale corrosion or product fouling of the internal surfaces. This condition slows transmission and distribution capacity, and can require more than just routine maintenance if it remains unaddressed. Interior corrosion, fouling and leakage in pipeline systems will adversely impact bottom-line operations. ...
