Rand Water | Integrated Annual Report 2025

MANUFACTURED CAPITAL Our Manufactured Capital represents the physical, material, and infrastructure assets that enable Rand Water to deliver on its mandate of supplying quality water reliably to our customers. It encompasses the vast network of treatment plants, pumping stations, pipelines, reservoirs, and related infrastructure that forms the backbone of our operations. Continuous investment in the maintenance, upgrading, and expansion of these assets is essential to sustaining uninterrupted water supply and meeting the growing needs of the communities we serve.

We have a distribution network of over 3,500 km of large diameter pipelines, feeding 60 strategically located service reservoirs. In the 2024/25 financial year, Rand Water supplied an average of 4 574 Mℓ/d of potable water to our consumers, up from the previous financial year of 4 554 Mℓ/d . The Peak day demand is 5 161 Mℓ/d achieved in October 2024, compared to 5 168 Mℓ/d achieved in March 2024. 5 199 Mℓ/d is the highest Peak day demand achieved so far. Rand Water primarily draws raw water from the Vaal River System. Two (2) river stations (Zuikerbosch and Vereeniging) abstract, purify and pump into the network some 98% of the water supplied to our customers. About 90% of this water is further pumped by four (4) booster stations situated on the southern side of the Witwatersrand ridge, namely Eikenhof, Zwartkopjes, Palmiet and Mapleton. Customer supply as follows: • Zuikerbosch/ Vereeniging direct – southern Gauteng and northern Free State (localised), in addition to supplying to all booster pumping stations. • Eikenhof – Western and north-western Johannesburg, the West Rand and greater Rustenburg. • Zwartkopjes – Central Johannesburg and a high-lying portion of the East Rand. • Palmiet – Eastern and northern Johannesburg, large parts of Tshwane, and western portions of Ekurhuleni. • Mapleton – Central and eastern parts of Tshwane and Ekurhuleni, and selected areas in Mpumalanga. INTEGRATED APPROACH TO INFRASTRUCTURE DEVELOPMENT INFRASTRUCTURE DEVELOPMENT PLAN The Infrastructure Development Plan (IDP) serves as a high-level strategic roadmap that identifies future project requirements. It is informed by ongoing condition assessments, performance monitoring, and demand and capacity analysis, which guide both renewal needs and augmentation requirements. The IDP is reviewed and updated annually to provide a five-year outlook for planned projects. From this, a structured programme of renewals and augmentations is developed, supported by a consolidated master schedule of existing and new projects. This process enables the preparation of a reliable five-year capital expenditure (Capex) estimate. INTEGRATED EXECUTION PLAN Rand Water has adopted the Integrated Execution Plan (IEP) approach to accelerate project delivery and ensure beneficial use after completion of each package. The aim is to combine projects into a single contract to eliminate dependencies on completing other contracts, as is currently the case. These larger packages are designed to attract service providers with higher CIDB grades, ensuring strong financial capacity, proven reputation, and the expertise required to manage complex projects. Projects will also be delivered through a turnkey approach, appealing to high-calibre contractors with specialised knowledge.

Rand Water plans to implement R46 billion over the next five (5) years to meet the objectives set out in the IDP.
