Sewerage & Drainage

Upgrading urban water supply systems is rapidly changing the texture and increasing the volume of the wastewater generation. The storm water volume is also increasing very fast due to seamless urbanization. Such modernization demands for advanced products, for improvement of all components, especially underground collection infrastructure for wastewater as well as stormwater Management. Alcorr DWC PE pipe is a tailor made Product to tide over any impasse in this regard. The System Components of S&D Projects are crystallized as:

  • Catch pits
