The Berg Water Management Area is a constrained system where water requirements are projected to exceed yield by 2019. A hydro-economic analysis indicates that by 2040, the water supply deficit could cost the region over R146 billion and nearly 650,000 jobs annually, with the City of Cape Town bearing the highest opportunity costs. The report identifies systemic failures in current top-down planning and financing, recommending the establishment of a Regional Water Utility and the use of multi-criteria decision tools to prioritize 'smart' water use over first-come, first-served allocations.

The Berg Water Management Area (WMA) faces a projected water supply deficit of approximately 300 million m3 per year by 2040, which could cost the region over R146 billion and 650,000 jobs annually. Current planning systems are fragmented, treating water and economic development as independent variables, and local municipalities often lack the capacity to secure off-budget financing for infrastructure. The brief recommends that the Western Cape Government support municipalities in integrating water planning into Integrated Development Plans (IDPs), advocate for a regional water utility, and employ hydro-economic modelling to prioritise interventions.

The report examines the Berg Water Management Area (WMA) as a 'constrained catchment' where water demand is projected to outstrip supply due to climate change, population growth, and urbanisation. It identifies a misalignment between legislated water allocation processes and economic development planning, noting that water is often treated as an independent variable rather than a co-dependent factor. To address this, the study developed a regional hydro-economic GIS model to forecast water requirements and value the economic opportunity costs of supply deficits, and a Multi-Criteria Decision Analysis (MCDA) tool for the Saldanha Bay Local Municipality to prioritise development applications based on socio-economic outcomes rather than a first-come-first-served basis. Findings indicate that while the City of Cape Town dominates regional economic value, the West Coast municipalities of Swartland, Saldanha Bay, and Bergrivier face the most significant constraints to future development. The report recommends the creation of a regional water utility and the use of the provincial government's Sustainable Water Management Plan (SWMP) as a forum for integrated planning.

The report investigates water constraints in the Berg Water Management Area (WMA) and Saldanha Bay, South Africa. It finds that traditional linear planning—based on generalized growth percentages—fails to account for the 'stepped' water demand of large industrial projects, potentially leading to supply shortfalls between 2017 and 2019. The document argues for a 'smart' allocation model that links water productivity (GDP/jobs per drop) to resource allocation and explores a Water Exchange Network (WEN) to reduce freshwater intake by up to 15% through industrial water cascading. It also highlights that high salinity in the Berg River poses a significant operational cost and production risk to the steel processing industry in Saldanha.

The report details a project to analyze water consumption and economic productivity in the Western Cape to identify constraints to growth. It introduces a conceptual model to determine the "right" water sources, quality, and pricing for specific developments, particularly in Saldanha Bay. The project implemented statistical water accounting and water footprint assessments for the Berg Catchment to establish a baseline for water-economic productivity.
