Introduction

Mining and industrial operations are among the most water-intensive activities, requiring reliable water supply for processes such as mineral extraction, ore beneficiation, cooling, dust suppression, power generation, and domestic use. At the same time, these sectors face increasing regulatory scrutiny, rising water scarcity, and growing expectations for sustainable and responsible water use.

Mining & industrial water management focuses on optimizing water abstraction, minimizing freshwater demand, maximizing reuse and recycling, managing mine water and effluents, and ensuring full compliance with environmental and groundwater regulations.

At Hydrodynamic Modeling Consultancy Pvt. Ltd., we deliver integrated mining and industrial water management solutions that combine hydrogeological investigations, water balance analysis, numerical modelling, and regulatory compliance to achieve operational efficiency and long-term sustainability.

What Is Mining & Industrial Water Management?

Mining and industrial water management is a systematic approach to planning, monitoring, optimizing, and regulating water use throughout the life cycle of a project—from planning and operation to closure.

It addresses critical questions such as:

• How much water is required and from which sources?

• What is the impact of abstraction and dewatering on groundwater and surface water?

• How can freshwater demand be minimized through reuse and recycling?

• How should wastewater and mine water be treated and managed?

• Are operations compliant with CGWA, environmental clearance, and pollution control norms?

Effective water management ensures resource security, regulatory compliance, and cost efficiency.

Key Components of Mining & Industrial Water Management

1. Water Requirement Assessment and Water Balance

• Process-wise water demand assessment

• Source identification (groundwater, surface water, mine seepage)

• Preparation of site-specific water balance diagrams

• Identification of losses, reuse, and recycling potential

A robust water balance forms the backbone of sustainable water planning.

2. Mine Water and Dewatering Management

• Assessment of mine seepage and inflow

• Dewatering impact on surrounding aquifers and wells

• Optimization of mine sump capacity and pumping schedules

• Reuse of mine water for dust suppression, beneficiation, and greenbelt

Scientific dewatering management prevents uncontrolled groundwater depletion and community impacts.

3. Groundwater Impact Assessment and Sustainability

• Hydrogeological and aquifer characterization

• Long-term groundwater level trend analysis

• Radius of influence and impact zone assessment

• Numerical groundwater modelling for mine-life scenarios

These studies support CGWA compliance and sustainable abstraction planning.

4. Water Recycling, Reuse, and Zero Liquid Discharge (ZLD)

• Process water recycling and cascade reuse

• Effluent Treatment Plant (ETP) and Sewage Treatment Plant (STP) optimization

• Treated water reuse for industrial and auxiliary purposes

• Reduction of freshwater intake and wastewater discharge

Efficient reuse directly reduces water costs and regulatory risk.

5. Rainwater Harvesting and Recharge Planning

• Rooftop and surface runoff harvesting

• Managed Aquifer Recharge (MAR) structures

• Mine-void and abandoned pit recharge

• Compliance with recharge obligations under CGWA and EC conditions

Recharge measures enhance groundwater sustainability and regulatory acceptance.

6. Monitoring, Instrumentation, and Compliance

• Installation and calibration of water flow meters

• Telemetry-based groundwater abstraction monitoring

• Groundwater level and quality monitoring networks

• Periodic compliance reporting and audits

Monitoring ensures transparent and defensible water governance.

Role of Modelling in Mining & Industrial Water Management

Numerical modelling strengthens water management by enabling predictive and scenario-based planning.

Applications of Modelling

• Simulation of mine dewatering impacts

• Assessment of long-term groundwater sustainability

• Optimization of abstraction and recharge strategies

• Climate variability and extreme rainfall analysis

Models such as MODFLOW and SEAWAT provide regulators and project owners with science-backed decision support.
