Algoa Reconciliation Strategy Steering Committee Meeting Highlights

Slide Note

The Algoa Reconciliation Strategy Steering Committee discussed various agenda items including NMBM water requirements, drought measures, implementation progress, desalination schemes, and financial implications of interventions. Key projects to support increased water demand were outlined, alongside updates on drought declaration, funding received, and approval for specific projects. The financial implications included costs estimates for operational efficiency, awareness campaigns, water conservation, groundwater schemes, improving older dams, ward boreholes, and desalination plants.

DROUGHT MITIGATIONS Nooitgedagt optimisation & temporary treatment Optimisation: Stanford Rd booster transferring 60 Ml/d. Increase Chelsea Res. zone into Lorraine / Fairview / Charlo. Increase Motherwell Res. Zone into New Brighton / Deal Party. Increase the supply into Uitenhage / KwaNobuhle. Pump station to Despatch Tower. Pump station Chelsea Res to KwaNobuhle

DROUGHT MITIGATIONS Nooitgedagt optimisation & temporary treatment (cont.): Temporary Treatment: Nooitgedagt: 140 Ml/d Treatment & 210 Ml/d Pumping Capacity. 70Ml/d spare pumping capacity. Temporary Treatment Plant at Grassridge Reservoir: Treating of 70 Ml/d spare capacity that can be pumped. Reintroduced 1992 Drought Plan. Pipe interconnections currently being carried out. Sedimentation & disinfection. Water then gravitates to Motherwell pumpstation where it is blended with the remaining 140 from the low level scheme before distribution to customers.

11.2 WC/WDM at NMBM WC/WDM Focus Areas: Zoning Pressure reduction. Meter replacement. Pipe replacement. Leak repairs: Contractor support. Recruitment of additional plumbers (13 recruited in the last 12 months).

11.3 NOOITGEDAGT LOW-LEVEL SCHEME IMPLEMENTATION AND FINANCING Phase2: 99% complete 140Ml/day available since July 2017. Phase3: 30% complete. 2 Major delays: Health & Safety Non Payment Funded from NT and DWS through Amatola Water as per DORA Anticipated completion date February 2020.

11.4 DESALINATION OF SUNDAYS RIVER IRRIGATION RETURN FLOWS. NMBM: Limited Feasibility study conducted. Volumes of water not enough for long term solution. Water to be transferred to western side of Metro where problem/shortage during droughts exists. Huge financial costs associated ( R500M) Awaiting outcomes of the feasibility study by DWS as agreed in meeting before NMBM can proceed.

11.5 RE-USE OF WATER TREATED TO INDUSTRIAL STANDARDS: Fishwater Flats WWTW: Currently limited industrial re-use being utilised especially in the Deal Party industrial area. 110Ml/day Re-use scheme for Coega IDZ planned. 60Ml/day from FWF WWTW 50Ml/day from Coega WWTW. Coega IDZ EIA approval stipulates Re-use of treated water for Coega industrial use. Estimated cost of R600mil. NMBM does not have these funds available.

11.5 RE-USE OF WATER TREATED TO INDUSTRIAL STANDARDS: Coega WWTW: Feasibility studies completed. Potential plant size of 110Ml/day. Plant required for the ultimate full development of the Coega IDZ. Plant broken into industrial and domestic lines due to effluent variances in quality. Motherwell North development and sewer line to support commissioning of plant. Estimated cost of WWTW is R3bil. NMBM does not have these funds available

11.6 GROUNDWATER - COEGA KOP IMPLEMENTATION Coega Kop aquafer is the best possible groundwater potential. EIA approval for 25Ml/day of groundwater abstraction. Implementation: Phase1 - feasibility study complete. Phase2 - Exploration boreholes drilled. Phase3 - Production borehole contract and relevant pipelines commenced. (R55M). Phase4 - Construction of 20M/day water treatment plant to commence within 2019. (R160M).

11.7 SCHEMES & DROUGHT INITIATIVES OTHER GROUNDWATER Water Augmentation: Churchill Dam Kamesh Reservoir Moregrove Fault Drought Augmentation: Borehole drilling to support swimming pools Provision of non potable water points throughout the NMBM 30 Wards @ 3 boreholes each when required.

11.8 DESALINATION SCHEME NMBM 60 ML/D Feasibility study nearly complete and finalised. Site determined through a Multi disciplinary Criteria Method Planned for construction in phases up to 60Ml/day. Estimated cost of R3bil. NMBM does not have the funding available. Funding and procurement model need assistance.

11.9 DESALINATION SCHEME MARINA SEA SALT Marina Salt approached NMBM with possible potable water provision through their construction of a sea water desalination plant. 26Ml/day potentially available for usage. NMBM currently investigating the contractual and legal implications of an agreement between the two parties, Marina Salt & NMBM. Appears that National Treasury / Minister determination is required.
