Project schedule: Construction of 2C commenced, completion by March 2014. Phased completion following implementation of water reconciliation study and funding availability Progress / Challenges The mining houses did not want to sign the off take agreements (citing that the water was too expensive); TCTA could not obtain funding from the capital market because of this, TCTA already had committed funds on the projects because of the detail design already 90% complete National Treasury had to fund the revised directive to implement Phase 2C (pipeline from the De Hoop dam to Steelpoort) Phase 2C important as the De Hoop dam is almost completed. Facilitation process amongst stakeholders to agree on the BDS configuration. Still a possibility of off budget funding when facilitation process is completed. 30 April 2012

Luvuvhu River Government Water Scheme: Nandoni Steel Pipelines Project schedule: The Lukalo-Lambani, NN20B and NR6 bulk lines to the north of Nandoni Dam and Xikundu Weir respectively will be completed by end of October 2012. The construction of the Vuwani bulk pipeline has been split into three contracts. The contractors established the site in June 2012 and the work will be completed by May 2013. The Valdezia bulk pipeline, is being constructed by DWA Construction: North and will be completed by April 2013. Progress/Challenges Updated water demand figures are significantly higher than the previously estimated, requiring larger pipe diameters . Approval for roll-over of R200 incl vat has not yet been received from National Treasury. Risks or challenges Possible delay with supply of pipe materials Cash flow of emerging contractors Labour/Industrial action/strikes or go slows Compliance with stringent environmental conditions Local Water distribution Infrastructure to be implemented by Local Authorities Decisions required: None Project description: Construction of the five new pipelines to complete Nandoni bulk distribution system and to replace problematic GRP pipelines, including the Valdezia Pipeline Reasons for under-spending in the 2011/2012 year : The budget of R203 million was allocated before the design had commenced. The appointment of the professional service provider who is responsible for the design and construction supervision was finalized during February 2012, which impacted on the completion of the designs and caused a significant delay. The pipe diameters had to be changed because of the higher water demands due to the later design options (previously 2010 and now 2025). The project was accelerated by awarding the construction of the pipeline to three different contractors. Province: Limpopo Jobs impact: About 300 jobs Projected cost to completion: R750,1 million Project Scope: This project includes new steel pipelines for Xikundu Distribution Scheme and Nandoni Distribution Scheme

Dam Safety Rehabilitation Programme (DSRP) The Klein Maricopoort Dam near Zeerust and Rust de Winter Dam near Hammanskraal was successfully completed in the fourth quarter to bring the total number of dams completed to four for the financial year. Various rehabilitation design projects are carried out using internal staff and progressing well. Numerous projects are promoting labour intensive methods and maximising job creation. Slow procurement processes are hampering progress where DWA Construction is involved. Shortage of staff doing rehabilitation design internally is delaying progress. Non appointment of consulting engineering PSPs are delaying implementation of various projects. Non appointment of mechanical term contracts are delaying implementation of various work. Unavailability of as-built drawings increases the possibility of variations on contracts
