Water Stewardship for Economic Resilience – Updates from the Collaboration in Rosslyn
In South Africa, the NatuReS programme continues to drive efforts to establish a stewardship multi-stakeholder partnership (SMSP) for the Rosslyn Industrial Area (RIA). SMSPs are participatory formats in which the public sector, private sector and civil society develop joint solutions for more sustainable management and use of natural resources. In this context, NatuReS supports the ongoing work in the Rosslyn Improvement District (RID) led by the Capital City Business Chamber (CCBC) towards a more sustainable way of production and improved water efficiency. The goal for the RIA is heading towards an Eco-Industrial Park (EIP) approach. Rosslyn is located in the northern part of the City of Tshwane (Pretoria) and is home to major industries including a concentration of automotive industries and large companies such as BMW, Nissan, South African Breweries, Renault, TATA, and Nampak. More than 200 businesses operate from here and provide employment to more than 20,000 workers.

Assessing the state of water metering
To support measures for improved water security in the RIA, NatuReS contracted the consultancy GITEC, which specialises in digital water and wastewater measurement as well as water resource efficiency. For a week in early August, the partners went on several site visits to discuss solutions for the state of water and wastewater metering and the potential for more resource efficient ways of production. The engagements included the City of Tshwane Municipality as well as nine medium, large, and multinational companies from several sectors active in the RIA, such as automotive, leather processing, packaging, train maintenance, beverages, and feed production.
The City of Tshwane expressed their interest in collaborating around the digitisation of meters for water supply as well as wastewater discharge quality. Since so far, the reading of meters and the assessment of effluent quality happens manually, which is labour-intensive, costly, and time-consuming. On the companies’ side, all meter their water supply and treat it, if necessary, before discharging to the municipal sewer system. While some companies already use digital equipment to assess their water consumption, some expressed interest in adopting such technology.


Wastewater reuse as significant potential for Rosslyn
Beyond metering, all companies are very keen to explore opportunities for water reuse, both internally and with other businesses in the area. Given the magnitude of industrial demand, economically feasible reuse schemes could yield substantial benefits for reliability, cost control, and environmental performance. For example, one company’s treated wastewater could become the process water of another company and does not necessarily need to be of potable quality. This same concept could also be explored for water used for heating and cooling.
This appetite for collaboration illustrates the growing interest in industrial symbiosis, a form of industrial ecology where companies collaborate to exchange resources like materials, energy, and water to reduce waste and improve efficiency. Therefore, NatuReS together with the CCBC, is planning to organise a workshop for interested companies to strategically discuss these topics and develop joint projects.

Water security – a question of economic stability for South Africa
These local-level efforts are particularly important as South Africa faces significant and interlinked natural resource pressures that threaten long-term economic stability and social cohesion. Water, in particular, has emerged as one of the most critical pressure points. Climate change, ageing infrastructure, and mounting demand from both industry and growing urban populations are further exacerbating the already chronic water stress.
Especially the Gauteng Province, home to the administrative capital of Pretoria and the economic capital of Johannesburg, is projected to face serious challenges in the future due to limited water sources and a rapidly growing population. Concurrently, the province is the economic engine of the country contributing to over 34% of South Africa’s total GDP, and accounting for nearly 7% of Sub-Saharan Africa’s GDP. Therefore, ensuring long-term water security is crucial to maintaining this status.
Partnerships to align industrial growth with responsible resource management
These implications have also been understood in Rosslyn, where the seeds of collaboration are already being planted. By bringing businesses, government, and civil society to the same table, the SMSP approach is proving that sustainable water security and industrial competitiveness are not opposing, but mutually reinforcing goals. Building on work happening in the East London IDZ, Rosslyn can demonstrate how South Africa’s economic hubs can successfully align industrial growth with responsible resource management. It is a powerful reminder that a Just Transition is not only possible, but achievable when we act together.
