What We Do in Kolkata
Water engineering built for West Bengal's requirements.
Our Kolkata office at Eco Intelligent Park, Sector V, Salt Lake, supports projects across West Bengal and the eastern states. Many sites here sit on low-lying ground with a high water table and heavy monsoon rainfall, which shapes how tanks are founded, how pump rooms are protected and how much storm buffering a plant needs.
Hospitality and heritage buildings
Kolkata's hotels and older commercial buildings often have to retrofit a treatment plant into an existing structure. MBR and compact STPs suit these sites because they produce reuse-grade water from a small footprint.
Salt Lake and New Town
Sector V and New Town house IT campuses and commercial towers with large daytime sewage loads and a strong case for recycling water into flushing and cooling.
Haldia and the Hooghly belt
Haldia's petrochemical and port-based industries, and older manufacturing along the Hooghly, need ETPs designed for oily and chemical effluent, since discharge to the river is closely watched.
Across the eastern states
Beyond West Bengal, Navbharat Water has delivered plants across the eastern region: STP and ETP for KMV Projects Hospital in Chaibasa, Jharkhand, STPs for L&T Construction in Cuttack and Vedanta FACOR in Odisha, and an STP with WTP for Hyatt Regency Bodhgaya in Bihar.
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. Navbharat Water's Kolkata team handles WBPCB consent-to-establish and consent-to-operate.
