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
