Groundwater Exploration and Drilling
Water is life and at Near Surface, we specialise in finding and developing sustainable groundwater sources that communities, industries, and governments can rely on.
Our groundwater services cover the full cycle, from exploration to supply:
- Exploration & Assessment – Hydro-census surveys, hydro-chemical testing, geophysics, and site characterisation to identify the most viable water sources.
- Borehole Siting & Drilling – Precision siting and professional drilling using advanced techniques suited to diverse geological conditions.
- Pump Testing & Yield Analysis – Determining sustainable borehole capacity and developing operational guidelines.
- Equipping & Infrastructure – Complete borehole installations, including pumps, monitoring systems, and fittings for long-term reliability.
- Water Quality & Treatment – Comprehensive water testing and customised treatment systems to meet potable and industrial standards.
With decades of expertise, we deliver affordable, technically sound, and dependable groundwater solutions from rural supply schemes to large-scale industrial applications.
Groundwater Monitoring
Safeguarding groundwater resources is critical for public health, environmental protection, and long-term sustainability. We provide end-to-end monitoring and management solutions that empower clients to make informed decisions about their water resources.
Our services include:
- Monitoring Borehole Installation – Strategic placement of observation wells for continuous groundwater level and quality assessment.
- Water Quality Analysis – Regular sampling and laboratory testing for chemical, biological, and physical parameters.
- Contamination Transport Modelling – Advanced simulations to track and predict contaminant movement in complex geological settings.
- Groundwater Risk Assessments – Identifying and managing potential threats from agriculture, mining, landfills, and wastewater facilities.
- Regulatory Compliance – Designing monitoring programmes aligned with South African and international environmental standards.
- Groundwater Database Development – Creating customised, client-specific databases that centralise monitoring data, streamline reporting, and support data-driven resource management.
By integrating field monitoring, laboratory testing, advanced modelling, and data management, we deliver actionable insights that protect groundwater quality and ensure its sustainable use.
Groundwater Modelling
Understanding how water moves underground is key to sustainable management, contamination control, and resource planning. We use advanced modelling tools to simulate complex groundwater systems and provide clients with actionable insights for decision-making.
Our groundwater modelling expertise includes:
- Numerical Groundwater Flow Simulation – Predicting aquifer behaviour under different pumping and recharge scenarios.
- Contamination Transport Modelling – Tracking pollutants in dual-porosity and fractured systems to design effective remediation strategies.
- Surface Water–Groundwater Interaction – Assessing exchanges between rivers, wetlands, and aquifers to optimise water use and protect ecosystems.
- Riverbank Filtration Studies – Evaluating the natural filtration process along riverbanks for sustainable drinking water supply solutions.
- Saline Intrusion & Mixing Models – Identifying risks in coastal aquifers and planning mitigation strategies.
- Water Quality Monitoring & Data Integration – Incorporating field data into models for accurate calibration and long-term management.
By combining scientific expertise, field data, and cutting-edge modelling platforms, we help clients optimise groundwater use, safeguard quality, and plan infrastructure with confidence.
Geotechnical Engineering
Every successful infrastructure project begins with a solid understanding of the ground it is built on. Our geotechnical engineering services provide the insight and assurance needed to design and construct safe, resilient, and cost-effective structures.
Our expertise covers:
- Drill Management, Logging & Sampling – Accurate subsurface data collection to characterise soil and rock properties.
- Pipeline Route Investigations – Detailed assessments to optimise routes and reduce construction risks.
- Foundation Studies – Geotechnical evaluations for reservoirs, water storage tanks, pump stations, and other infrastructure.
- Groundwater & Flooding Risk Assessments – Identifying potential risks to safeguard communities and assets.
- Construction Material Testing – Evaluating soils, aggregates, and materials to ensure compliance with engineering standards.
- SHEC (Safety, Health, Environment & Community) Management – Integrating sustainability and risk management into every project phase.
With our multidisciplinary team and advanced investigation methods, we provide reliable data and practical solutions that help clients minimise risks, control costs, and build-construct with confidence.
