The Western Cape Government Department of Human Settlements appointed Lukhozi for the design and implementation of a R54m sewage diversion contract.  Lukhozi provided Civil, Structural, Electrical and Mechanical Engineering , Environmental and Project Management services.

The project commenced in November 2016 and was commissioned in November 2019 and comprised the upgrading of the Nooiensfontein Sewage Pumpstation and the construction of a new sewage rising main​ ​which diverts flow from the Zandvliet WWTW to the Bellville WWTW.

The key features of this successful project include:

  • The pumping facility includes a new grit trap, screening facility and pumpstation with an upgraded pumping capacity of 100 l/s;
  • The pumping facility is located in a flood plain and with shallow ground water levels;
  • The pumpstation is 10m below the ground level with a dry well / wet well configuration
  • The 6km long 355mm diameter rising main was laid in densely populated areas dealing with many existing services;
  • The rising main required the installation of two 1m diameter microtunnels approximately 60m long beneath the R300 dual carriage highway and railway tracks.

Below are a few photos of the completed installation.
