Rand Sandton Engineering provides end‑to‑end water resources engineering services that integrate hydrology, hydraulics, environmental science, climate resilience, and infrastructure planning. Our approach ensures that water systems are sustainable, reliable, and capable of supporting long‑term socio‑economic development—particularly in regions facing increasing climate variability, rapid urbanisation, and growing demand for water security.

We work across the entire water cycle, from catchment to consumer, delivering solutions that balance engineering feasibility, environmental protection, and institutional capacity.

Water Supply and Sanitation Planning

We design and implement sustainable water supply solutions that ensure reliable access to safe, clean water for communities, industries, and public institutions. Our work spans the full project lifecycle from resource assessment and system planning to engineering design, optimization, and long‑term management. We support clients in developing resilient water infrastructure that responds to growing demand, climate variability, and operational constraints.

Our expertise includes water source development, treatment system design, distribution network modelling, non‑revenue water reduction, and the integration of smart technologies for efficient monitoring and management. Through evidence‑based planning and practical engineering solutions, we help deliver water systems that are affordable, resilient, and aligned with national and international standards for public health and sustainability.

We help governments and utilities plan and implement reliable, inclusive, and sustainable water and sanitation systems.

Expertise includes:

  • Water demand forecasting and supply planning
  • Non‑revenue water (NRW) reduction strategies
  • Rural and urban sanitation planning
  • Wastewater collection and treatment system design inputs
  • Water safety planning and risk assessments
  • Utility performance improvement and capacity building

Our solutions strengthen service delivery and support long‑term operational sustainability.

Hydraulic Engineering and Water Infrastructure Design

We provide engineering design inputs for water supply, stormwater, and hydraulic systems that are efficient, resilient, and cost‑effective.

Hydrological Modelling

We apply advanced hydrological modelling to understand water movement, predict system behaviour, and support resilient water resource planning. Our work helps clients assess flood risks, evaluate catchment responses, optimise water supply systems, and design infrastructure that can withstand climate variability and extreme events.

Our expertise includes rainfall–runoff modelling, floodplain and river flow simulations, groundwater–surface water interaction analysis, and scenario testing for climate change impacts. By combining high‑quality data, robust analytical tools, and local context, we deliver reliable insights that inform policy, engineering design, and long‑term resource management.

River and Dam Engineering

We provide specialised engineering services for the planning, design, assessment, and rehabilitation of river systems and dam infrastructure. Our work supports safe water storage, flood management, hydropower development, and the long‑term resilience of critical water assets.

Our expertise spans hydrological and hydraulic analysis, dam safety evaluations, sediment and erosion management, spillway and outlet works design, and the rehabilitation of aging or high‑risk structures. We also support river restoration, channel stabilization, and ecosystem‑sensitive interventions that balance engineering performance with environmental integrity.

By integrating advanced modelling, field investigations, and international best practice, we help clients develop river and dam systems that are safe, efficient, and sustainable over their full operational life.

 

Our capabilities also include:

  • Design of water supply systems, pumping stations, and reservoirs
  • Stormwater management and urban drainage design
  • Flood control structures (levees, retention basins, culverts)
  • Dam safety assessments and rehabilitation planning
  • River engineering and channel stabilisation

Our designs incorporate climate‑resilient standards and international best practice.

Hydrology and Catchment Management

We apply advanced hydrological modelling and watershed analysis to support sustainable water resource planning.

Urban Hydrology

We provide urban hydrology solutions that help cities manage stormwater, reduce flood risks, and build climate‑resilient infrastructure. Our work focuses on understanding how rainfall interacts with the built environment and designing systems that safely convey, store, and reuse water in dense urban settings.

Our expertise includes stormwater modelling, drainage network design, flood risk assessment, sustainable urban drainage systems (SuDS), and nature‑based solutions that enhance urban resilience. By integrating engineering analysis with environmental and urban‑planning considerations, we support cities in creating safer, greener, and more sustainable water management systems.

 

Our expertise includes:

  • Catchment and watershed assessments
  • Surface and groundwater interaction studies
  • Hydrological modelling (rainfall‑runoff, flood routing, drought analysis)
  • Water balance studies and resource availability assessments
  • Sedimentation analysis and erosion control planning
  • Integrated catchment management strategies

These services help clients understand water availability, manage risks, and plan for long‑term resource sustainability.

Flood Risk Management and Disaster Resilience

We integrate engineering, climate science, and risk analysis to reduce vulnerability to floods and extreme weather events.

Capabilities include:

  • Flood hazard mapping and inundation modelling
  • Flood risk assessments for infrastructure and communities
  • Early warning system design inputs
  • Nature‑based flood mitigation solutions (wetlands, riparian buffers)
  • Climate‑resilient flood management strategies
  • Emergency preparedness and disaster risk reduction planning

These services help clients protect lives, infrastructure, and economic assets.

Water Policy, Governance, and Institutional Strengthening

We assist governments and water authorities in developing policies, regulatory frameworks, and institutional systems that support effective water governance.

Capabilities include:

  • Water policy development and regulatory reform
  • Institutional capacity assessments and strengthening plans
  • Water pricing, tariff modelling, and economic analysis
  • Stakeholder engagement and participatory water governance
  • Monitoring and evaluation frameworks for water programmes

Our work strengthens institutions and supports sustainable, equitable water management.
