PROJECT 231080YNB - IMPLEMENTATION READINESS REPORT FOR DEPARTMENT OF WATER AFFAIRS WORLEY- CLIENT REV DESCRIPTION ORIG REVIEW PARSONS DATE DATE APPROVAL APPROVAL Issued for internal review E Deysel N/A 2013-12-13 N/A Page i DR RUTH SEGOMOTSI MOMPATI DISTRICT MUNICIPALITY REGIONAL BULK INFRASTRUCTURE GRANT - IMPLEMENTATION READINESS REPORT EXECUTIVE SUMMARY The study concerns the towns of Bloemhof and Schweizer-Reneke, which are to benefit from the proposed scheme. These towns are situated within the Lekwa-Teemane and Mamusa Municipalities respectively, which are both within the Dr Ruth Segomotsi Mompati District Municipality (DRSMDM) of the North West Province. Schweizer-Reneke‟s population growth and the shortage of water drives this project, thus alternative sources of bulk water supply were sought. The smaller towns of the Mamusa Municipality, namely Amalia, Migdol and Glaudina, have sufficient local groundwater resources to meet the current demands. Bloemhof is also encountering water shortages due to the insufficient capacity and decline of infrastructure, which attributes to the increasing water demand. The primary objective of this report is to illustrate how the proposed Mamusa Bulk Water Scheme meets the prescribed requirements to qualify for RBIG funding. The Dr Ruth Segomotsi Mompati District Municipality is applying for RBIG funding to counter fund the capital cost associated to the project. Schweizer-Reneke was founded in 1888. The town is situated in the Harts River valley on the R34 between Bloemhof and Vryburg. Bloemhof is situated on the Vaal River, roughly 50 kilometres between Christiana and Wolmaransstad, and it was established in March 1866. Both towns‟ economies revolves around agriculture, agriculture related industries and diamond mining. The population of Schweizer-Reneke and Ipelegeng is projected to increase from 64 261 persons in 2010 to 86 391 persons in 2030 or a 35% increase. This brings about an increase in the Average Annual Daily Demand (AADD) of 2 304 mᵌ/d with a total AADD in 2030 of 9 373.2 mᵌ/d. The demand is currently met by two water sources, i.e. the Wentzel Dam as primary supply and the Townlands Borehole Scheme as supplementary source in dry periods. The Wentzel Dam is situated in the Harts River and has a full supply capacity of 6.203 million mᵌ. The 1:100 year stochastic firm yield of the source, with no ecological water release, is calculated at 1.08 million mᵌ. This is the amount of water available for primary water use. The Townlands Borehole Scheme consists of 15 boreholes with a sustainable yield of 1 786 mᵌ/d. These boreholes can only be used when the water level in the Wentzel Dam drops below 4.82 m during the period 1 January to 30 September or below 4.56 m during the period 1 October to 31 December of any year. Page i 2013-12-13 DR RUTH SEGOMOTSI MOMPATI DISTRICT MUNICIPALITY REGIONAL BULK INFRASTRUCTURE GRANT - IMPLEMENTATION READINESS REPORT The population growth of Bloemhof is projected at 20% over the period from 2010 to 2030. This implies that the 2010 population of 29 259 persons will increase to 35 357 persons in 2030. As a result, the AADD is projected to increase from 5 898 mᵌ/d to 7 904 mᵌ/d. Bloemhof's water is abstracted from the Vaal River at the weir near the Bloemhof Dam where the existing abstraction works is situated. Water is conveyed to the existing water treatment works (WTW) in Bloemhof. The existing facilities were commissioned in 1992 and designed for a capacity of 9 600 mᵌ/d serving the projected 2008 population. The abstraction works have abstraction difficulties during drought periods and flood occurrences due to its design. However, the abstraction works at the weir and the WTW are running at full capacity and hence the capacity of these works need to be increased. The current abstraction volumes are approximately 3.3 million mᵌ/annum and the estimated 2030 water demand is 5.37 million mᵌ/annum. The current registered volume is 1.6 million mᵌ/annum, thus application is to be made to DWA for a further allocation volume of 3.77 million mᵌ/annum. The application process is underway. Several options were investigated during the feasibility phase of the project. The preferred and approved option is to provide purified water from the Bloemhof water treatment works (WTW) abstracting water from the weir in the Vaal River near the Bloemhof Dam. This implies that the following infrastructure and facilities be established and/or upgraded: Increase the existing capacity of the abstraction works in Bloemhof by either upgrading the current facility or relocating the facility to the Bloemhof Dam wall Increase the capacity of the WTW in Bloemhof to meet the projected water demand of the area Establish a bulk water supply pipeline between Bloemhof WTW and the Schweizer-Reneke bulk storage facility The intention of the project is to provide basic services to the community, supporting economic growth and developments in the area. The overall project cost is at R 429 440 739.58 (VAT and escalation included). Based on the norms, number of indigents, associated users and enabling economic environment the social component of the project was calculated at 50.5%. The social component of the project amounts to R 216 867 573 (including VAT). An amount of R 16.65 million was approved for the 2013/2014 financial year by DWA and it is expected that the deficit will be funded by DWA in the following financial year.

The current demand of both towns exceeds the capacity of the infrastructure and no further development can take place without the upgrading of the infrastructure. The project is also in line with the strategic planning documentation including the WSDP, and IDP. The current abstraction volumes are approximately 3.3 million m3/annum, while the estimated 2030 water demand is 5.37 million m3/annum. The current registered volume is 1.6 million m3/annum thus application is to be made to DWA for a further allocation volume of 3.77 Mm3/annum. The application was submitted to DWA and awaits approval. The dBAR is in the process of being updated and the expected submission date of the Final BAR to the Department Economic Development, Environment, Conservation and Tourism – North West Provincial Government is January 2014. The submission is being delayed till January 2014 since the DEDECT requested that the public participation be reviewed because of the time elapsed since the first submission. The dBAR can only be submitted with the inclusion of the reviewed public participation process. The Dr Ruth Segomotsi Mompati District Municipality will be the owner of the infrastructure and it is proposed that the operation and maintenance be conducted by the Lekwa-Teemane Municipality for the abstraction works and water treatment works initially. Once the total scheme is completed, negotiations between both Municipalities and Sedibeng Water can commence regarding the overall O&M. Three landowners were consulted for available land for the construction of a booster pump station and elevated tank, the repeater signal station and a second elevated tank. The negotiation process with the landowners is well underway. As soon as an agreement is reach with the landowners, the legal documentation will be drafted and registration of the servitudes will be done according to the National Water Act (NWA) Act 36 of 1998. The existing and proposed extension of the WTW will be located within the existing site boundaries and therefore no land ownership or other legal issues need to be resolved. However, the electricity supply will have to be upgraded. The process is underway with Eskom and Lekwa-Teemane Municipality.
