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
