Umgeni Water is a regional water authority in the Kwa-Zulu Natal Province of South Africa. Umgeni Water’s main concern is the provision of bulk water to the cities of Durban and Pietermaritzburg and their surrounding areas. As a bulk supplier, Umgeni Water operates and is responsible for major dams, waterworks, pipelines and other water supply infrastructure. Umgeni Water Process Evaluation Facility (PEF) was built in 1992, for the provision of innovative solutions to the challenges in water and wastewater treatment by:

  • designing and evaluating systems using emerging technologies and testing their appropriateness to local conditions including rural potable water supply
  • engaging in collaborative applied research with both national and international water research organs for advancing and sharing knowledge in water and wastewater treatment
  • building research capacity in the water industry through provision of a conducive and stimulating centre of excellence at the PEF.

PEF also collaborates with academic institutions and other water authorities both nationally and internationally. Umgeni Water has been in the forefront of research on the application of membranes for sludge dewatering, and potable water and wastewater treatment. It has been intimately involved with universities in the development of crossflow woven fibre membranes for waterworks sludge dewatering, capillary ultrafiltration membranes and microfiltration for household water treatment systems. PEF is currently in the initial stages of piloting household systems in rural communities.

In addition, PEF recently investigated: high-rate clarification in potable water treatment, upflow direct filtration for potable water treatment, small water systems for rural water application, process control using particle counting, biological removal of Fe and Mn from ground water, fluoride dosing for small water treatment systems, and operational strategies for the cost-effective use of ozone in potable water treatment.
