Waste Water Treatment IndustryAccording to American Waterworks Association industry database, there are approximately 876,000 miles of municipal water piping in the United States, while the sewer system consists of 16,400 publicly owned treatment facilities that release 41 billion gallons of wastewater per day.

The total annual direct cost of corrosion for drinking water and sewer systems is $36 billion, which includes the costs of replacing aging infrastructure, leaks, corrosion inhibitors, external coatings due to sun or heat exposure, and cathodic protection. PVC coated conduit systems, like those from Calbond, can be integrated within a system and protect the workings of the WWTP from corrosive damage. Calbond offers a complete line of PVC coated conduit, fittings and conduit accessories for the protection of electrical conduit systems in highly corrosive environments.

  • The corrosive environment of the mining industry limits the lifespan of the processing equipment and as a result, decreases production and endangers the lives of employees within the mine
  • Aerobic and anaerobic microorganisms present in mining water also contribute to the extremely corrosive environments. Aerobic species produce sulfuric acid, making the environment very acidic. Anaerobic microorganisms reduce sulfate and sulfides by using available hydrogen and producing hydrogen sulfide (H2S)
  • PVC coating is available on galvanized rigid steel and aluminum conduit
  • UL® Listed and NEMA RN-1 compliant with no exceptions
  • UL6 Listed with both zinc and PVC as primary coatings, providing two layers of corrosion protection
  • UL PVC adhesion performance tested (DYJC E226472), where conduit is sequentially subjected to air oven conditioning exposure test and resistance salt spray (fog) and adhesion test of ANSI/UL6
  • Specially formulated urethane internal coating provides the longest available product lifecycle
  • Proven to provide corrosion protection at a fraction of the cost of stainless steel conduit
  • Broadest product offering for corrosion protected conduit systems
