| Trappies sewer rehabilitation to reduce pressure on existing sewer network | <p>This major project will rehabilitate a 3,1km section of the Trappies sewer, running from Nazli Street to Hammond Street.<br></p><p>Due to the pipeline's location, where traditional open-trench methods are not feasible, trenchless technology will be used. The project will repair the aged sewer line, restoring it to optimal functionality and allowing high sewage volumes to flow without the frequent failures currently being experienced, especially during heavy winter rains when the sewer system is flooded due to stormwater ingress. </p><p><span></span></p><figure class="subtopic-fullsize-img"><img class="responsive" src="https://resource.capetown.gov.za/cityassets/Media%20Images%202/Trenchless%20technology%20being%20used%20at%20the%20site%20Trappies%20Sewer%20Rehabilitation%20Project%20site%20work.jpg" alt="" style="width:1900px;" /></figure><strong>Update on the Trappies Sewer Rehabilitation Project</strong><p></p><p>A service provider has been appointed to facilitate the rehabilitation on the 900mm diameter pipe segment, which runs from the Lourens River Sewer Pump Station to Fagan Street, down Joubert Street and De Villiers Street, up until Main Road. </p><p>Currently the design and works project documentation are being finalised for work to commence immediately after the tender process is concluded. Work on site is anticipated to begin towards the end of October 2024, with a construction period of approximately 12 to 14 months. </p><p>Unfortunately, multiple service disruptions are an ongoing challenge in the area. The City is conducting emergency repairs where pipe bursts and sewer collapses occur, in an effort to minimise the impact while the long-term rehabilitation project is being implemented.</p><p>This past week the following incident was attended to:</p><p><strong>Corner of Thompson and Fagan Street</strong></p><ul><li>Emergency repairs began on a collapsed sewer on Wednesday night (21 August) when the appointed contractor prepared the site to connect a new six-metre long pipe at the corner of Thompson and Fagan Streets. Pipe installation was successfully completed on Thursday, 22 August 2024.</li><li>First the line was isolated by inserting a balloon in the manhole near the work area. Sewage was then over-pumped to the furthest manhole, to prevent sewage flow into the section where the pipe was connected.</li><li>Early on Thursday morning, the contractor encountered high volumes of water inside the main 900mm diameter sewer pipe, causing interconnected upstream sewer network pipes to overflow. Further investigations are under way to identify the sources of this water.</li><li>By Thursday evening, the new pipe was successfully connected and all affected streets were cleaned.</li><li>Today, Friday, 23 August 2024, the contractor is backfilling the trench.</li></ul><p>'While the City has robust plans to address the challenges of ageing infrastructure, it's important to note that many sewer blockages and overflows can be prevented through responsible behaviour. Illegal stormwater-to-sewer connections and the disposal of rags, electronics and building rubble into the sewer system puts undue strain on the entire network, exacerbating these issues. </p><p>'Our collective and collaborative efforts in reporting incidents and reducing blockages can reduce the frequency of sewer collapses and overflows,' said the City's Mayoral Committee Member for Water and Sanitation, Councillor Zahid Badroodien.</p><p><span><figure class="subtopic-fullsize-img"><img class="responsive" src="https://resource.capetown.gov.za/cityassets/Media%20Images%202/Concrete%20boulders%20removed%20from%20the%20sewer%20network.jpeg" alt="" style="width:1069px;" /></figure></span>The Water and Sanitation Directorate is providing regular updates on the progress of repairs in the affected areas and is committed to continuing engagements with the community.</p><p>Details of the next community meeting will be communicated to residents once logistics are finalised.
