What We Do in Kolkata
Water engineering built for West Bengal's requirements.
Every site has different constraints — raw water quality, discharge destination, available footprint, and regulatory authority. NWPL's Kolkata engineers design for your specific conditions, not a generic template.
WBPCB Compliance
West Bengal Pollution Control Board — What Industries Must Know
WBPCB mandates ETP for all industries discharging into the Hooghly River. Hospitality and residential projects in Kolkata require STP with BOD ≤30 mg/L. NWPL's Kolkata team handles WBPCB consent-to-establish and consent-to-operate.
