BirlaNu Rainwater Pipes are designed to meet the urgent need for sustainable water management in todayâs context of growing water scarcity. Engineered with precision, these half-cut rooftop drainage pipes and fittings efficiently collect rainwater from roof edges-where water naturally accumulates-and channel it seamlessly for storage or discharge. Ideal for both residential and commercial buildings, BirlaNu Rainwater Pipes help prevent waterlogging and structural damage by channelling rainwater safely away.
