SWR Soil, Waste & Rainwater Drainage Systems
Manufactured by Bhardwaj Enterprises, Three Golden Arrows SWR pipes are specifically designed for non-pressure building drainage, waste discharge, and roof rainwater harvesting. SWR systems must endure aggressive household detergents, biological wastes, temperature fluctuations, and structural settling vibrations without ever permitting seepage.
Available in 75 mm and 110 mm diameters (within the confirmed up to 110 mm / 4" boundary), our SWR pipes conform to IS 13592 specifications in both Type A (for rainwater downspouts & ventilation stacks) and Type B (heavy-wall for soil & waste discharge).
Ring-Fit Elastomeric Gasket
Integrated elastomeric sealing ring absorbs thermal expansion/contraction and building vibration while providing an impenetrable 100% leak-proof seal.
Anti-Clog Hydrodynamics
Ultra-smooth non-stick inner walls eliminate grease accumulation, sludge adhering, and root penetrations common in conventional CI or cement drainage pipes.
Detergent & Chemical Immunity
Resistant to laundry bleaching agents, corrosive drain cleaners, organic acids, and sewage gases like hydrogen sulfide (H2S).
UV & Rodent Resistant
Special anti-rodent additives and exterior UV-stabilizers ensure exterior vertical shafts remain intact and free from rodent bite damages.
SWR Specifications: Type A vs. Type B
Three Golden Arrows SWR pipes are produced in standard 3-meter and 6-meter lengths with grooved ring sockets or plain solvent cement sockets:

| 75 mm (2-1/2") | Type B | 3.2 mm – 3.8 mm | Soil & Waste Discharge | Ring-Fit / Solvent Socket |
| 110 mm (4") | Type A | 2.2 mm – 2.7 mm | Rainwater Downspout & Vent Pipe | Ring-Fit / Solvent Socket |
| 110 mm (4") | Type B | 3.2 mm – 3.8 mm | Heavy Soil & Waste Discharge | Ring-Fit / Solvent Socket |
Building Sanitary & Drainage Applications
Specialized soil, waste, and rainwater drainage piping available in 75–110 mm with Ring-Fit rubber ring and Solvent-Fit sockets:
Multi-Story Soil & Waste Stacks
Vertical discharge stacks carrying blackwater from water closets and greywater from bathroom sinks, showers, and kitchen appliances.
Commercial Malls & Office Complexes
Heavy-duty sanitary drainage networks designed for high-frequency public usage, chemical drain cleaners, and grease trap connections.
Vent Stacks & Pressure Relief
Vent stack piping equalizing atmospheric pressure within plumbing traps to prevent water-seal siphonage and expel sewer gas above the roof.
Terrace Stormwater Downpipes
High-volume exterior facade down-takes channeling heavy monsoon rainfall from roof parapets safely into storm drains or harvesting sumps.
