Industrial Water Reuse in Africa: Qualify the System Before You Sell the Equipment

Industrial water is becoming a strategic operating issue across Africa. For equipment suppliers, engineering firms, investors and technology companies, the opportunity is not simply to sell a treatment unit. It is to solve a measurable production problem: unreliable supply, rising water cost, discharge risk or constrained expansion.

JOTS Group is a Ghana based holding company and Africa opportunity entry platform. The following separates verified market signals from our analysis of how a company should qualify an opportunity.

Verified signals: reuse is moving toward investable scale

On 1 August 2025, the World Bank Group’s Scaling Water Reuse report said municipal and industrial reuse could grow eightfold by 2040 to 430 million cubic metres per day, with as much as US$340 billion in potential investment. It also noted that the business case is strongest when wastewater is close to the point of use, including industrial parks.

A concrete African example appears in an IFC disclosure dated 27 August 2025 and updated 19 March 2026. It reports that textile operations at the GDIZ industrial park in Benin averaged about 21,000 cubic metres of water use per month in 2025 and achieved an internal reuse rate of 85–90%. The same disclosure requires monitoring, pre-treatment for higher pollutant loads and fit-for-purpose treatment.

At larger scale, IFC announced on 13 September 2024 a €100 million loan supporting a 219-kilometre pipeline for desalinated water to OCP’s mining and production operations in Morocco. IFC said the pipeline was designed for 80 million cubic metres a year; OCP’s stated 2027 targets included 560 million cubic metres of desalinated-water capacity and 60 million cubic metres of treated wastewater.

JOTS analysis: where the commercial opportunity sits

These facts do not mean every reuse project is bankable. They suggest a growing market for water audits, metering and sensors, modular treatment, pumps and membranes, process redesign, automation, laboratory services, operations support and performance-based maintenance. The strongest offer will usually combine equipment with commissioning, operator training, spare parts and verified water-quality outcomes.

Five questions before entering the market

1. What is the customer’s binding constraint? Quantify downtime, purchased-water cost, discharge fees, permit risk and the value of additional production.

2. What quality is required at each point of use? Cooling, washing, boilers and process water need different specifications. Design from laboratory data and a complete water balance, not from a generic capacity figure.

3. Who owns compliance and residuals? Confirm abstraction rights, discharge limits, sludge handling, monitoring duties and the approvals needed for reuse.

4. Does the commercial model match the customer? Compare an equipment sale with leasing, build-operate-transfer or payment linked to treated volume and quality. Test foreign-exchange exposure and lifecycle costs.

5. Can the system be supported locally? Map consumables, calibration, maintenance skills, response times and spare-parts inventory before promising uptime.

Actionable takeaway

Begin with one site and a paid diagnostic: establish the water balance, test influent and required output quality, define a baseline cost per cubic metre, and propose a pilot with acceptance criteria. Expand only after the technical result and customer economics are verified.
