Job Description

Job Purpose
The Water/Sanitation Engineer designs, implements, and maintains water supply, wastewater treatment, and stormwater management systems to ensure public health, environmental compliance, and sustainable resource use. The role addresses South Africaxe2x80x99s water scarcity challenges through innovative engineering solutions.Key Responsibilities
1. Water Supply Systems

• Design potable water networks (pumping stations, reservoirs, pipelines) per SANS 10252.
• Optimize water loss management (NRW reduction strategies).
• Model hydraulic systems using EPANET, WaterGEMS, or InfoWorks WS.

2. Wastewater Management

• Plan sewerage systems (gravity/pressure sewers) compliant with SANS 1200-L.
• Design wastewater treatment plants (activated sludge, MBR, anaerobic digestion).
• Implement effluent reuse systems for industrial/agricultural applications.

3. Stormwater & Flood Control

• Develop drainage masterplans using SWMM, PCSWMM, or HEC-RAS.
• Design SUDS (Sustainable Urban Drainage Systems) for flood mitigation.
• Conduct culvert/bridge hydraulic analyses.

4. Regulatory Compliance

• Secure water use licenses (WUL) from DWS per NWA (National Water Act).
• Ensure Blue Drop/Green Drop certification standards for municipal systems.
• Monitor effluent quality against DWAF discharge limits.

5. Project Execution

• Supervise construction of water infrastructure (pipelines, WTPs).
• Manage operation & maintenance (O&M) contracts for municipal systems.
• Lead community engagement for sanitation behavior change programs.

Required Qualifications

• BEng/BSc in Civil/Environmental/Chemical Engineering.
• Professional Registration:

• ECSA PrEng
