MINING WATER PROJECTS

Water is one of the most critical resources within the mining industry. From exploration and mine development through production, mineral processing, closure, and rehabilitation, effective water management directly influences operational efficiency, environmental compliance, production continuity, and long-term sustainability. Mining operations must continuously balance water supply requirements with increasingly stringent environmental regulations governing water use, discharge, and resource protection.

Thwalokuhle provides specialised water infrastructure, treatment, recovery, and management solutions tailored specifically to the mining sector. Our multidisciplinary team combines expertise in process engineering, water treatment, mechanical systems, electrical and instrumentation engineering, fabrication, automation, and project execution to deliver integrated water solutions that support mining operations throughout the asset lifecycle.

Our experience includes mine dewatering systems, bulk water supply infrastructure, process water treatment plants, tailings water recovery systems, wastewater treatment facilities, acid mine drainage treatment, pump stations, pipelines, storage infrastructure, and water reuse systems. These solutions help mining companies secure reliable water supplies, minimise environmental impact, optimise water consumption, and maintain regulatory compliance.

A key area of focus for Thwalokuhle is the treatment and beneficiation of Acid Mine Drainage (AMD). Across South Africa and the broader African mining sector, AMD remains one of the most significant environmental and operational challenges facing mining companies. Traditionally viewed as a liability requiring treatment and disposal, AMD contains a substantial recoverable water resource that can be transformed into a valuable operational asset through the application of appropriate treatment technologies.

Our philosophy extends beyond compliance-driven treatment. We develop integrated mine water recovery solutions that convert contaminated mine water into reusable process water, industrial utility water, dust suppression water, and environmentally compliant discharge streams. By combining advanced treatment technologies with practical engineering solutions, we assist mining companies in reducing freshwater demand, improving environmental performance, lowering operating costs, and enhancing long-term water security.

As water scarcity, environmental accountability, and operational efficiency become increasingly important across the mining industry, Thwalokuhle assists clients in developing sustainable water strategies that improve resource utilisation while supporting safe, responsible, and profitable mining operations.

02 STANDARDS

REGULATORY STANDARDS

Standard 01

National Water Act (Act 36 of 1998)

The National Water Act governs the use, protection, management, and conservation of South Africa’s water resources. Mining operations are subject to strict controls relating to water abstraction, storage, treatment, discharge, and environmental protection.

Standard 02

Water Use Licence (WUL) Requirements

Most mining activities require Water Use Licences to regulate water-related activities including abstraction, storage, diversion, dewatering, discharge, and waste management. Our engineering solutions are developed with full consideration of licence conditions, monitoring obligations, discharge limits, reporting requirements, and environmental compliance requirements.

Standard 03

Mine Health and Safety Act (MHSA)

Water infrastructure forms an essential component of mine safety management. Dewatering systems, process water systems, pipelines, storage facilities, and treatment plants must be designed and maintained to protect workers and mining operations. Thwalokuhle incorporates safety-by-design principles, risk mitigation measures, operational safeguards, and maintainability considerations into all mining water projects.

Standard 04

ISO 14001 – Environmental Management Systems

Our water treatment, recovery, and reuse systems support environmental management objectives by reducing freshwater consumption, improving discharge quality, minimising environmental risks, and promoting responsible water stewardship.

Standard 05

ICMM Water Stewardship Principles

Thwalokuhle develops water management solutions aligned with recognised sustainability principles, supporting responsible resource utilisation and long-term environmental performance.

Standard 06

Global Industry Standard on Tailings Management (GISTM)

Tailings storage facilities require careful water management to ensure safe operation, environmental protection, and long-term stability. Our water recovery, pumping, monitoring, and treatment solutions support responsible tailings management practices.

Standard 07

Occupational Health and Safety Act (OHSA)

Water treatment plants, pump stations, pipelines, and associated infrastructure must be operated safely to protect workers and surrounding communities. Safety considerations are integrated throughout engineering design, construction, commissioning, operation, and maintenance activities.

3. Services

Thwalokuhle designs and installs mine dewatering systems incorporating borehole pumps, sump systems, transfer pump stations, pipelines, reservoirs, and automated control systems that effectively manage water levels while protecting mining operations.

Our treatment solutions ensure that process water meets operational requirements while reducing scaling, corrosion, equipment wear, and production interruptions.

Thwalokuhle develops integrated AMD treatment and water recovery solutions that address both environmental obligations and operational water requirements, applying neutralisation, clarification, filtration, membrane treatment, and polishing processes tailored to each mine water stream.

We conduct detailed mine water recovery studies that evaluate water chemistry, treatment technologies, operational costs, reuse opportunities, and long-term sustainability objectives.

Our services include abstraction systems, pipelines, reservoirs, pump stations, storage facilities, and distribution networks designed to ensure uninterrupted water availability in remote operations.

Thwalokuhle designs recovery systems that capture, treat, and return water to the process, reducing freshwater demand and improving sustainability.

04OUR TECH

Technology

RO

Reverse Osmosis (RO)

Reverse osmosis is widely applied within mining operations to remove dissolved salts, sulphates, metals, and other contaminants from process water, wastewater, and acid mine drainage streams.

UF

Ultrafiltration (UF)

Ultrafiltration provides effective removal of suspended solids, colloidal particles, bacteria, and organic contaminants and is frequently used as pretreatment for reverse osmosis systems and water recovery applications.

Lamella

Lamella Clarifiers

Lamella clarification technology provides efficient solid-liquid separation while minimising plant footprint requirements.

Dosing

Chemical Dosing Systems

Chemical treatment is essential for pH correction, coagulation, flocculation, metal removal, sulphate reduction, scale control, and disinfection. Thwalokuhle designs automated dosing systems that optimise performance while reducing chemical consumption.

Pumps

High-Capacity Pumping Systems

Our pumping systems are designed to maximise reliability, energy efficiency, and operational flexibility for long-distance and high-head transfers.

Monitoring

Real-Time Water Quality Monitoring & SCADA

Continuous monitoring provides visibility into treatment performance and compliance. Systems include sensors, telemetry, alarm management, and remote operational control.

Tailings

Tailings Water Recovery Technologies

Modern recovery technologies enable the extraction and reuse of valuable process water from tailings facilities, improving sustainability while reducing freshwater demand and operating costs.

GIS

GIS and Digital Asset Mapping

GIS platforms provide accurate asset mapping and support maintenance planning, operational management, and infrastructure expansion projects.
