New Lanseria Wastewater Treatment Works: Access Road

Client: Johannesburg Water/Zitholele Consulting Engineers.

Project description: Detail design for the upgrading of an existing gravel road to surfaced road to provide access to the proposed new Lanseria Wastewater Treatment Works. The section of road to be upgraded is 6.9 km in extent.

Scope of work: Traffic assessment, hydraulic modelling and analysis, stormwater management, culvert design, accommodation of existing services (including major overhead power transmission lines), geometric design, road signage, and obtaining wayleaves for implementation. The project has included several challenges, in particular those relating to a network of powerlines and services within servitudes in close proximity to the footprint of the  road coupled with having Northern Farm a proclaimed nature reserve immediately adjacent to  the road.
