Don’t Turn A Blind Eye To Corrosion: Using The HydraSnake To Spot Early Signs of Damage.

How to determine the condition and serviceability of distribution mains

With water and wastewater pipelines rapidly ageing across North America, the risk of sudden leaks and burst failures are higher than ever. Between 2012 and 2018, pipe breaks saw a 27% increase in occurrence, causing millions of dollars in damage, repair costs, and significant disruption to local communities. Partnering with an experienced analysis team like PICA Corp to perform regular condition assessments of your lines is one of the best ways to stay on top of the health of your pipes, as well as to avoid the headaches and misfortune that come with a sudden failure.

The PICA HydraSnake

PICA’s inventory of tools include leading solutions like our HydraSnake. As the world’s first field-proven in-line inspection service,  with access to water mains through hydrants, the HydraSnake offers exceptional capability for evaluating corrosion wall losses on cast and ductile iron water distribution mains. Designed to provide a direct measurement of wall thickness for the full length of the main, the HydraSnake is able to sense graphitic corrosion, pitting, and erosion with remarkable accuracy.

Versatile and Convenient

The HydraSnake is self-contained and crafted to easily navigate tees and elbows, continuously recording wall thickness as it travels through the pipe. Advantages of this technology include:

-Proactively identify problem spots before leaks occur

  • Extend the life of your pipeline and enhance your options for rehabilitation
  • Prioritize pipe replacement
  • Provide baseline survey data
  • Access to the main provided via hydrant (no excavation required)
