DWC stands for Double Wall Corrugated pipe. It's commonly used in drainage and sewage systems because of its durability and flexibility. The double wall design provides extra strength, and the corrugated exterior allows for easy installation and flexibility in tight spaces. It's often made from high-density polyethylene (HDPE) and is resistant to corrosion and abrasion.

DWC (Double Wall Corrugated) pipe has several highlights:
1. *Strength and Durability*: Its double-wall construction provides excellent strength and durability, making it suitable for various applications, including drainage, sewerage, and cable protection.
2. *Flexibility*: DWC pipes are flexible, allowing for easy installation even in challenging terrains without the need for extensive jointing.
3. *Corrosion Resistance*: They are resistant to corrosion, which extends their lifespan and reduces maintenance requirements.
4. *Lightweight*: Despite their strength, DWC pipes are lightweight, making transportation and handling easier.
5. *Cost-effective*: The combination of durability, flexibility, and corrosion resistance makes DWC pipes a cost-effective solution over their lifespan, as they require minimal maintenance and replacement.
6. *Variety of Applications*: They are used in a wide range of applications, including stormwater management, sewage systems, telecommunications, and electrical cable conduits.
