Nu-Drain uPVC Pipes

Nu-Drain pipes are made as per IS:15328 and marked with ISI mark. These pipes are available in different stiffness classes as given in the table below. In addition to the pipes in 110mm to 315mm sizes with rubber ring type sockets, pipes up to 200mm sizes are available with solvent weld type socket ends. Plain ended pipes upto 250mm are supplied with a separate couplers having unique click ring and rubber-seal design. Only 400mm size pipes are supplied with plain end and solvent weld type couplers. The pipes are available in 3m & 6m lengths.

Nu-Drain pipes are advanced underground drainage solutions designed for efficient and sustainable water management. Manufactured using uPVC, they are lightweight, durable, and resistant to corrosion, chemicals, and biological attacks. Nu-Drain systems are ideal for gravity-based drainage applications in residential, commercial, and industrial projects. Their smooth inner surface ensures superior flow characteristics with minimal blockages. These pipes are easy to install using leak-proof push-fit joints, reducing installation time and cost. Compliant with IS standards, Nu-Drain is a reliable choice for rainwater harvesting, soil waste, and stormwater drainage systems, offering long service life and low maintenance in harsh underground environments.

eco Drain

Eco-drain® pipes are not solid wall pipes but feature a unique structure with multiple “holes” running longitudinally through the wall thickness. This innovative design makes Eco-drain® pipes significantly lighter and more cost-effective than traditional PVC pipes of equivalent stiffness, and far lighter than concrete pipes with similar load-bearing capacity. Their performance and benefits have led to widespread acceptance and usage in several European countries.

Available in sizes up to 400mm, these pipes come with either plain ends or socketed ends equipped with elastomeric rubber rings. Despite their lighter weight, Eco-drain® pipes maintain stiffness and flexibility comparable to solid wall plastic pipes and meet international standards. Depending on the pipe size, they can offer a weight reduction of 10% to 35% compared to solid wall pipes in the same stiffness class.
