OchriO Johannesburg Water About Us Banner
 » Water and Sanitation » Networks


We provide water and sanitation services to areas stretching from Orange Farm in the South to Midrand in the North, Roodepoort in the West and Alexandra in the East.

The entity operates within the six regions mentioned below, with ten network depots and six wastewater treatment plants:

  • Region A: Midrand/Ivory Park/Diepsloot/Kya Sand
  • Region B: Rosebank/Randburg/Emmarentia/Greenside/Melville/Northcliff/Parktown
  • Region C: Roodepoort/Constantia Kloof/Northgate
  • Region D: Doornkop/Dobsonville/Protea Glen
  • Region E: Alexandra/Wynberg/Sandton
  • Region G: Orange Farm/Ennerdale/Lenasia

The entity supplies 1,574 megalitres (Ml/day) of potable (fit to drink) water per day. The water is procured treated from Rand Water and then gets distributed by Johannesburg Water.  The water complies with the SANS 241:2015 national drinking water standards and Johannesburg Water is Blue Drop Certified.

Wastewater gets collected and reticulated via 11,786 km of wastewater network and 37 sewer pump stations where 973 Ml/day of sewage is treated, this process is done at our six wastewater treatment works of which two are biogas-to energy plants which are responsible for converting methane gas to energy.

The entity has a water network of 11896 km, a sewer network of 11 413 km and six wastewater treatment plants with a combined replacement value of approximately R50 billion. The challenge the entity is facing is that 46% of our asset base has been eroded implying only 53% remaining useful.

In response to our ageing infrastructure, JW has commenced with an Infrastructure Renewal Plan (IRP) which is aimed at increasing the renewal rate from 1% to 3.5% to eliminate backlogs. About R1 billion per annum is required to maintain our plan.
329 km of water mains has already been replaced against the target of 900km with the balance being planned for future. Similar plans are in the process for sewer, wastewater treatment works and for electro-mechanical plant.
