SWR Drainage System
WorldFlow SWR (Soil, Waste & Rainwater) pipes and fittings form a complete above-ground drainage system for modern buildings. Manufactured to IS 13592, they carry soil, waste, and rainwater quietly and reliably — with high impact strength, UV stabilisation for exposed stacks, and chemical resistance for everyday household effluents.
The system is available in both pasting (solvent) and ring-fit (rubber seal) variants, with a full range of bends, tees, traps, and cowls, so every stack and branch on the drawing can be built from one matched product family.
High impact strength for site handling and service
UV-stabilised for sun-exposed external stacks
Smooth bore prevents blockages and build-up
Resistant to household chemicals and effluents
Ring-fit joints absorb thermal movement
Quiet drainage performance in high-rise stacks
SWR Drainage System
A building's drainage has to work silently, every day, for decades — and stay sealed through seasons of expansion and contraction. WorldFlow SWR systems are engineered exactly for that duty.
The smooth inner bore keeps waste moving without build-up, while UV-stabilised material lets external stacks face the sun without becoming brittle. Ring-fit joints with EPDM seals accommodate thermal movement and make maintenance simple.
With a complete family of pipes, bends, tees, traps, and cowls manufactured to IS 13592, the entire drainage drawing can be executed with components that are made for each other.
