Sewerage & Drainage

Evolving urban water supply systems are rapidly changing the texture and increasing the volume of the wastewater generation. The stormwater volume is also increasing due to 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 problems from such occurrences. They can be used in diverse applications and connected with the relevant nodes:

  • Alcorr DWC Pipes: Class SN 8 or SN 4
  • Catch pits: connections through Alcorr pipes
  • Manholes: connections via Alcorr pipes
  • Sewage and Drainage lifting nodes
  • Storage for Storm drainage and run-off (storage systems) to ensure a hydraulically compatible flow for any downstream systems to avoid flooding
  • Rainwater harvesting: Such underground storage is also suitable for rainwater harvesting purposes
  • Irrigation Projects: Non-pressure bulk transport of liquids, using large-diameter DWC Pipes, helps in reducing capital and long-term maintenance costs significantly.

Apart from the DWC PE Underground Sewers / Storm Drains which is a standard Alcorr Product, with user-friendly systems, two of the above components, Manholes, and Flow Attenuation piped storage can also be configured by APEL on demand.
