Why Use DWC?

Advantage of DWC over Conventional piping systems:

  • Socio-environmental:
    Rapid laying of pipe does not disrupt urban and dense city clusters
  • Life Span:
    Time tested globally for 50 years with an extrapolated life graph of 100 years
  • Economical and light:
    Material saving 65% in comparison to plastic smooth wall pipes enables cost savings. Weight of pipe is only 5% of a traditional RCC pipe
  • Flexibility:
    In all types of contour conditions and under critical external surface pressure like in earthquake prone areas
  • Excellent hydraulic properties:
    Manning’s ‘N’ value of the pipe is 0.009-0.010 which also does not deteriorate during the entire life expectancy
  • Tightness:
    Leak proof and no infiltration of ground water even in unfavorable bedding contour
  • Chemical and biologically inertness:
    Deterioration of internal pipe condition on account of Crown Corrosion is non-existent
