This case study describes the Cape Agulhas Municipality's (CAM) transition toward a "Smart City 2.0" by implementing a smart groundwater monitoring and management system. To replace costly and inefficient manual monitoring of boreholes and reservoirs, CAM deployed a municipal-wide LoRaWAN Internet of Things (IoT) network. The project, piloted in Suiderstrand, uses real-time sensors and variable speed drives (VSDs) to improve resource oversight, reduce operational costs, and lower carbon emissions.

This industry brief by GreenCape examines the financial viability of using battery energy storage systems (BESS) for tariff arbitrage in the Western Cape, South Africa. It focuses on leveraging time-of-use (TOU) tariffs to reduce energy costs by charging batteries during off-peak periods and discharging during peak periods, particularly as the decline in loadshedding has left many existing BESS installations underutilised.

This industry brief by GreenCape reviews water and sanitation by-laws across municipalities in the Western Cape, South Africa. It evaluates the completeness and clarity of these local regulations against a 2005 model by-law, highlighting the implications for businesses—particularly water-intensive industries—regarding fees, audits, industrial effluent, and alternative water sources.

This municipal briefing by GreenCape describes the application of smart water systems—sensor-based networks for real-time data collection and analysis—within South African municipalities. It outlines the technical layers of these networks, provides case studies from Cape Agulhas, Saldanha Bay, and Bergrivier municipalities, and offers a checklist for municipalities to evaluate their readiness for such technology. The document also compares the long-term costs of smart ultrasonic meters versus conventional mechanical meters and lists funding and support resources for water infrastructure projects.

This municipal briefing by GreenCape outlines the implementation of smart water systems in South Africa, detailing their layered architecture, case studies from three municipalities, and a checklist for procurement. It specifically compares the long-term costs and benefits of ultrasonic smart meters versus conventional mechanical meters.
