Professional Experience
GIS Technician
Rand Water (Johannesburg, South Africa)
Aug 2021 – Present
• Provide GIS support for water infrastructure projects including pipelines, valves, and meters.
• Generate elevation profiles using DEMs to compare pipeline route options based on slope and construction feasibility.
• Designed and implemented a spatial database for the Planned Shutdown team integrating project data, infrastructure types, incidents, and census data.
• Developed a web-based application for tracking and reporting pipeline shutdowns, improving planning, response, and public communication.
• Provide data management and map production to support engineering teams.
Key Projects:
• Pipeline Elevation Analysis: Extracted Z-values from USGS DEMs using QGIS to assess slope on three proposed pipeline routes. Advised on final route selection based on gradient and cost implications.
• Planned Shutdown System: Designed a structured database with linked spatial and project attributes, integrated with a web map to optimize maintenance workflows and public notices.
Key Project Impacts:
• Reduced pipeline design costs by recommending optimal route using slope analysis from DEM-derived Z-values.
• Streamlined shutdown response coordination through custom GIS database and web dashboard integration.
• Supported rural infrastructure planning by independently capturing and managing spatial data in unaddressed communities.
• Designed and maintained spatial databases for water infrastructure, integrating technical and census data to support engineering and planning decisions across multiple departments.
