The document outlines the architecture of smart water systems, presenting case studies from Cape Agulhas, Saldanha Bay, and Bergrivier municipalities to demonstrate benefits such as cost savings and improved billing. It provides a checklist for municipalities to assess their readiness and a cost-benefit analysis comparing ultrasonic smart meters to conventional mechanical meters, while listing funding resources like SIDAFF and the DBSA's Non Revenue Water Programme.

The document outlines the structure of smart water networks and provides evidence from South African municipalities on how sensor-based systems can reduce costs and improve billing. It emphasizes that smart systems must address specific problems and be supported by internal IT capacity to avoid magnifying existing inefficiencies.

The Cape Agulhas Municipality (CAM) has implemented a phased smart water management system to replace manual monitoring of its groundwater sources. By deploying a LoRaWAN IoT network and digitising infrastructure in a pilot town, Suiderstrand, the municipality has achieved significant reductions in operating costs, vehicle travel, and carbon emissions. The project aims to provide a real-time holistic view of the water network to ensure the sustainable management of aquifers and improve service delivery efficiency.

The document assesses the potential for Western Cape businesses to leverage time-of-use (TOU) tariffs through BESS arbitrage, comparing the repurposing of existing systems against new installations. It finds that while upgrading existing BESS offers high internal rates of return (IRR), new installations are more sensitive to tariff escalation rates and investment horizons, with a 15-year outlook generally improving financial performance.

The document analyzes the alignment of water services by-laws in Western Cape municipalities with the 2005 Department of Water Affairs and Forestry (DWAF) model by-law. It identifies gaps in regulatory clarity, highlights specific business risks such as industrial effluent permits and water audits, and notes that municipalities with more recent updates generally provide better certainty for investors and operators.
