Marine outfalls public participation report now on the City’s website <p>The Minister will now take the public participation inputs into account in considering appeals to her Department's granting of permits for the City's marine outfalls. This process was necessary as the Minister is deciding the appeals some eight years after the permits were applied for. The Hout Bay permit was issued  in 2019. The Green Point and Camps Bay permits were only issued in December 2022. </p><p>'The City thanks every person who made a submission during the 60-day comment period. There is a clear public desire which is aligned to the City's strategic objectives to improve the treatment of the effluent currently discharged at the outfalls. </p><p>'A City-commissioned scoping study has already been completed in 2023 on future alternatives for the treatment of effluent currently discharged from the three marine outfalls, including the associated costs per proposal. In the interim, the City is focusing on short-term options for refurbishment, replacement, and maintenance to extend the lifespan of existing treatment infrastructure.</p><p>·        'Overall, the City is making major investments to improve wastewater treatment and upgrade sewers, to the benefit of inland and coastal water quality, with a 226% increase in the overall infrastructure budget, from R2,3bn in 2022/23 to R7,8bn in 2025/26. </p><p>·        'Future alternatives to marine outfalls effluent will be captured in the City's longer-term capital investment programme based on the outcome of further feasibility and environmental impact studies,' said Councillor Zahid Badroodien, Mayoral Committee Member for Water and Sanitation.</p><p>The public participation on the permits for the three outfalls ran for 60 days from 18 September - 18 November 2023, including opportunities to make submissions and attend six community engagement sessions. </p><p>A total of 1 979<strong> </strong>comments were received regarding the marine outfalls, all of which were categorised and responded to in detail. </p><p>Treatment quality was rated as the biggest concern, with 54% of all comments received highlighting this as the main reason for objecting to the marine outfall discharge permits for each of the three outfalls. </p><p>Comments on treatment are most commonly related to technology and methods, indicating a clear call to improve quality with better technology. Around a third of comments (31%) also related to improving processes in relation to the management and administration of outfalls. </p><p>·        The City has three marine outfalls which have been functioning for between 31 to 47 years: Camps Bay marine outfall (1977), Hout Bay marine outfall (1993) and Green Point marine outfall (1993). </p><p>All three of these outfalls are operating in accordance with their original design to dispose of screened effluent, with the Green Point and Hout Bay marine outfalls both receiving Green Drop Awards in 2022. </p><p>  The City continues to engage the DFFE to improve outfall operations, with the Department endorsing the City's suggestion to amend the terms of reference of the City's existing Section 80 Advisory Committee so that it operates as a Permit Advisory Forum (PAF) to monitor ongoing compliance.</p><p>The City is further sharing sampling data with the DFFE covering the range of constituents listed in the current outfall permits, and is engaging the Minister to align the permit outfall volumes to the design capacity of the outfalls in the current appeals determination process.</p><p>In total, 95% of Cape Town's wastewater is discharged from WWTW, compared to 5% from the three outfalls. Coastal outfalls are a global practice which is guided by local engineering and environmental pollution legislation and guidelines.</p><p><strong>Outfalls: Future alternatives</strong></p><p>A number of short, medium and long-term objectives were put forward in the study for the City's consideration in the recent scoping study on future alternatives regarding marine outfalls. The options are subject to budget availability and the outcome of further feasibility and environmental impact studies still to be undertaken:</p><p><strong>Short-term option: </strong></p><p>1.     Refurbishment of the existing marine outfalls infrastructure including pump stations, at an estimated capital expenditure cost of approximately R100 million. </p><p><strong>Medium-term options:</strong></p><p>1.     Extend the marine outfalls area to exclude the environmental protection area. Outfalls are currently located offshore, discharging beyond the intertidal zone, which could potentially be extended much further (for example, the Camps Bay outfall is currently 1 300m offshore, which can be extended 11,6km further offshore). </p><p>2.     Develop and construct the first phase of a new wastewater treatment works (WWTW), adjacent or in the vicinity of the existing marine outfalls.  </p><p>Both options together have a projected cost of between R2 billion and R3 billion in capital expenditure. </p><p><strong>Long-term options: </strong></p><p>1.     Construct pump stations and pipelines to convey wastewater to existing WWTWs and undergo extensive construction to extend the conventional facilities. This option could be aligned to medium-term option one and is estimated at a cost of R6 billion to R8 billion of capital expenditure.  </p><p>2.     Construct phase two of a comprehensive, new WWTW adjacent or in the vicinity of the existing marine outfalls, at an estimated cost of R2 billion to R3 billion (provided that medium-term option two is completed). </p><p>3.     Construct a comprehensive WWTW in phases, which is adjacent or in the vicinity of the existing marine outfalls comprising of primary treatment (approx. R3 billion), secondary treatment (approx.  R2 billion) and tertiary treatment (approx. R1 billion). </p><p> </p><p><strong>End</strong></p><p> </p><p><br></p>2024-03-11T22:00:00ZGP0|#1d539e44-7c8c-4646-887d-386dc1d95d70;L0|#01d539e44-7c8c-4646-887d-386dc1d95d70|City news;GTSet|#62efe227-07aa-45e7-944c-ceebacca891dGP0|#e457aab0-a4d3-4345-aed4-968da5c20de4;L0|#0e457aab0-a4d3-4345-aed4-968da5c20de4|Marine;GTSet|#2e3de6c1-9951-4747-8f53-470629a399bb;GP0|#2d9d26f8-fc9c-42a9-8fb2-4688d58c4173;L0|#02d9d26f8-fc9c-42a9-8fb2-4688d58c4173|Public participation10
