• Field Tests: In-situ sampling and on-site geochemical assessments to validate laboratory findings.
• Geochemical Modelling: Predictive modelling of water–rock interactions, contaminant transport, and long-term drainage quality using advanced geochemical software.

Our Waste Classification Services Include:
• Waste classification in accordance with South African legislation, including the National Environmental Management Act (NEMA) and the National Environmental Management: Waste Act (NEMWA).
• Classification of waste streams in line with the National Norms and Standards for the Assessment of Waste for Landfill Disposal and the National Norms and Standards for Disposal of Waste to Landfill.

WATER CONSERVATION AND WATER DEMAND MANAGEMENT (WCWDM)
We assist clients in:
• Optimising available water to meet operational requirements efficiently
• Exploring alternative water sources, such as groundwater, rainwater harvesting, and treated effluent
• Restoring polluted water to a quality suitable for industrial, agricultural, or municipal use
• Implementing WCWDM strategies in water-stressed areas, ensuring compliance with DWS regulations

Our Water Conservation & Demand Management Services Include:
• Water Balance Assessment and Calculations: Comprehensive evaluation of water inputs, outputs, losses, and recycling potential to optimise usage.
• Water Conservation and Water Demand Management (WCWDM): Development of strategies and programmes that reduce water consumption, improve efficiency, and ensure sustainable supply.
• Water Saving Strategies: Identification and implementation of practical measures to minimise water wastage and improve operational water efficiency.
• Water Availability and Supply Assessments: Technical evaluations of current and future water supply options, including source reliability and climate variability considerations.
• Water Demand Management Plans: Detailed, actionable plans that quantify water requirements, establish reduction targets, and integrate with environmental management programmes (EMPr/EMS).
