Since 2001, a private consortium (majority Veolia/Vivendi) has run a 47.5 ML/day plant reclaiming Durban's wastewater to near-potable industrial standard under a 20-year BOOT concession, supplying the Mondi paper mill and SAPREF refinery without municipal capital outlay.

Context

eThekwini Municipality sought to avoid capital outlay for large-scale wastewater reclamation while freeing up potable water supply for other users in Durban, South Africa.

Activities

Durban Water Recycling was awarded via a 1999 tender as a 20-year Build-Own-Operate-Transfer concession; construction began in 2000 and the plant was commissioned in May 2001, producing tertiary-treated, near-potable industrial water at 47.5 million litres/day, monitored against roughly 22 quality parameters. DWR (Pty) Ltd, majority-owned by Vivendi Water (now Veolia) with partners Zetachem, Khulani Holdings, Umgeni Water and Marubeni Europe, financed, built, owns and operates the plant.

Results

The two main industrial customers, the Mondi paper mill and the SAPREF oil refinery, had combined offtake of approximately 37,500 m³/day per a 2004 trade-press report. Total capital cost was reported at around R74 million (~US$5M at the time), financed by the Development Bank of Southern Africa, Rand Merchant Bank, a French government protocol loan and DWR's shareholders.

Conclusions

The frequently repeated claim that DWR cuts Durban's potable demand by about 7% could not be traced to a primary source with a clear publication date, and detailed customer-volume figures mostly date to 2004 with no more recent independent figures found; a 2020 EU Chamber of Commerce South Africa report notes the model has not been widely replicated elsewhere in the country, citing insufficient government buy-in and regulatory obstacles.

Conditions for success

  • Build-Own-Operate-Transfer structure let the private consortium finance and operate the plant without municipal capital outlay, funded through industrial tariffs
  • Two large, geographically adjacent industrial anchor customers (Mondi, SAPREF) provided stable offtake demand

Common failure modes

  • Model has not been widely replicated elsewhere in South Africa, per a 2020 EU Chamber of Commerce report citing insufficient government buy-in, outdated municipal wastewater technology and regulatory obstacles
