CGWA NOC in Bihar: Complete 2026 Guide for Industries via Bhu-Neer Portal

Bihar's industrial base — food and beverage units, cold storages, makhana and agro-processing, and the manufacturing corridors around Patna, Hajipur, Muzaffarpur and Begusarai — runs largely on groundwater drawn from the rich Gangetic alluvium. Bihar is a CGWA-regulated state, so groundwater NOC applications are filed on the national Bhu-Neer portal (cgwa-bhuneer.mowr.gov.in). With the CGWA's 2025-26 monitoring rules, compliance — including piezometers and water audits — has become tighter.

This guide explains who needs a CGWA NOC in Bihar, the thresholds, and the full process, documents, fees and compliance.

Who Needs a CGWA NOC in Bihar?

• Manufacturing units (MSMEs and large factories) across Patna, Hajipur, Barauni, Begusarai and Bihta
• Cold storages, food and beverage plants, dairy, and makhana / agro-processing units
• Group housing societies, shopping malls, hospitals, hotels and educational institutions above the prescribed threshold
• Infrastructure and construction projects drawing groundwater
• Mining and dewatering activities; commercial water-tanker services

Many bulk users crossing roughly 20 KLD of extraction fall within the NOC requirement, while purely domestic and agricultural use is generally exempt.

Gangetic Alluvium & Water Quality

Bihar sits on thick, productive alluvial aquifers, so yields are generally good — but that does not remove the need for a proper hydrogeological assessment or for water-quality diligence. Parts of the Gangetic belt have arsenic and iron issues, making a NABL water-quality report important for both compliance and process safety. CGWA's monitoring regime for the state emphasises real-time oversight: piezometer installation to track water levels and, for large extractors, an annual water audit.

Fees, Validity & Compliance

Central fees apply: ₹10,000 fresh, ₹5,000 renewal, ₹10,000 revival, plus annual abstraction charges by category and volume.
