On 30 January 2026 the Zeekoevlei Yacht Club (ZVYC) and partners issued an “Urgent Demand for Action” to the Executive Mayor of Cape Town, requesting a concrete plan to reopen the Ramsar site due to ongoing sewage flow and health risks. The communication highlighted the impact on over 10,000 young people and community members, demanded accountability for indefinite closures, and criticized the lack of transparency on water quality data.
Unfortunately it seems that the demand may be too late as this situation has been ongoing for many years.
Recent Shutdown Timeline
- September 2020: The vlei was closed on 17 September 2020 to investigate reported pollution incidents.
- July 2021 – February 2022: A major seven-month closure began on 6 July 2021 (some reports state 7 July or 8 July) following significant sewage spills. It only reopened on 25 February 2022 after E. coli levels returned to safer thresholds.
- December 2024 – January 2025: Closed on 13 December 2024 due to elevated blue-green algae. It was briefly reopened on 8 January 2025 after water quality improved.
- December 2025 – January 2026: Closed on 19 December 2025 following a sewage spill that led to high Microcystin levels.
- February 2026: Currently closed as of early February 2026 due to untreated wastewater entering stormwater drains.
While shorter closures occurred between 2014 and 2019, the frequency and duration have escalated since 2021. The City considers E. coli levels above 4,001 cfu/100ml to be an “unacceptable risk”. During the 2021 crisis, levels near the Zeekoevlei Yacht Club reached as high as 980,000 cfu/100ml.
Over the last decade, Zeekoevlei has faced severe environmental degradation, primarily driven by recurring sewage spills and toxic blue-green algae blooms.
Origin and Causes
The pollution stems from a combination of systemic and human factors:
- Infrastructure Failure: Ageing sewer pump stations, breakdowns of critical equipment like Archimedes screws, and frequent pipe blockages.
- Catchment Runoff: Untreated sewage from high-density informal settlements and rapid urbanisation in the surrounding catchments.
- Sediment Accumulation: Decades of nutrient-rich organic sediment on the lake bed foster toxic Microcystis algae blooms.
- System Abuse: Illegal dumping of foreign objects (rubble, tyres, rags) into manholes and the sewer system.
Responsible Parties
- City of Cape Town: Stakeholders and groups like Friends of Zeekoevlei and Rondevlei (FOZR) argue the municipality has failed to maintain infrastructure and lacks urgency in its response.
- Public/Residents: The City attributes many spills to “misuse” of the sewage system through illegal dumping and theft of manhole covers.
Affected Groups
- Clubs: Prominent organisations including the Zeekoevlei Yacht Club and the Alfred Rowing Club have had to indefinitely suspend activities.
- Residents: Local homeowners are often barred from the water due to health risks (e.g., lung infections and skin rashes). Many purchased property specifically for vlei access.
- Events: Major competitions, such as the Sonnet Nationals, have been cancelled or relocated due to unsafe E. coli levels.
Proposals and Solutions
- Dredging: A massive R265 million project is currently underway (the first in over 40 years) to remove over 360,000m³ of sediment from Storm Bay and Home Bay.
- Infrastructure Upgrades: A R200 million tender was recently awarded for refurbishing pump stations, improving screens, and modernising electrical systems.
- Nature-Based Infrastructure (NBI): Plans for the Liveable Urban Waterways (LUW) Programme include creating low-flow wetlands and riparian rehabilitation to treat stormwater before it enters the vlei.
- Catchment Forums: The establishment of the Zeekoe Catchment Management Forum to coordinate community and municipal action.
Economic Impact
- Direct Losses: Water sports businesses report up to an 80% decrease in turnover, leading to staff retrenchments.
- Tourism & Property: Pollution damages international “brand” appeal, with tourists and Olympic-level athletes cancelling training trips. Property values are at risk as the vlei’s primary attraction is lost.
- Investment Return: Economic analyses suggest that for every R1 invested in rehabilitating the catchment, there is a return of approximately R2 in net benefits from avoided damages and safeguarded revenue.
What is Being Done:
The rehabilitation of Zeekoevlei is currently in its most active phase in over 40 years. Below are the specific details on the dredging timeline and how you can support the community-led restoration efforts.
Dredging Project Schedule
The City of Cape Town launched this R265 million project in June 2025. It is expected to last approximately 26 months in total.
Phase 1: Storm Bay (In Progress):
- Goal: Removal of 207,000m³ of sediment.
- Status: As of December 2025, over 93,000m³ (nearly 45%) has been cleared.
- Operating Hours: To speed up progress, a noise exemption permit allows work from 06:00 to 19:00, Monday to Saturday, until December 2026.
Phase 2: Home Bay (Upcoming):
- Timeline: Expected to begin following the completion of Storm Bay (likely mid-2026).
- Duration: Estimated to take 14 months to remove 157,000m³ of sediment.
- Methodology: A floating suction dredger pumps sediment via a 4.3km slurry pipeline to drying ponds at the Cape Flats Wastewater Treatment Works.
Get Involved: The FOZR “Green Team”
The Friends of Zeekoevlei and Rondevlei (FOZR) is the primary community body working to restore the vlei’s ecological integrity.
The Green Team’s Mission: This community-based team focuses on maintaining litter traps, clearing invasive vegetation, and conducting “strike clean-ups” to intercept waste before it enters the water.
How to Join:
- Email: Contact the chair directly at FOZRchair@gmail.com.
- Volunteer Applications: You can also apply through the City of Cape Town Nature Volunteer Program, specifically requesting placement at the False Bay Nature Reserve (Zeekoevlei Section).
- Stay Updated: Follow their Official Facebook Page for announcements on upcoming weekend clean-up events and the annual AGM, typically held at the Zeekoevlei Yacht Club.
Annual Weir Draw-Down
Regardless of the dredging, the annual draw-down usually occurs in April/May. The weir is opened to lower water levels by 1.2 metres, allowing the vlei to be “flushed” by winter rains. This is often the best time for volunteers to assist with manual litter removal from the exposed banks.
Zeekoe Catchment Management Forum:
The Zeekoe Catchment Management Forum (ZK-CMF) was formally inaugurated in June 2024 to serve as a collaborative bridge between City officials and civil society.
For the most up-to-date 2026 engagement, you can reach out through the following channels:
City of Cape Town (Catchment Management):
- Contact Person: Chrystal Frantz (Corporate Services: Area South).

- Email: Fred.Monk@capetown.gov.za.
- Phone: 021 444 8788.
Forum Leadership: The forum is currently chaired by Liz Day, with Xoli Fuyani as vice-chair. They represent the interests of environmental experts and the community in discussions with the City.
Online & Community Channels
- Official Website: At the time of writing the zeekoeCMF.org.za web site was unavailable.
- Social Media: Follow the Zeekoe Catchment Forum Facebook Page for announcements regarding public meeting dates and infrastructure workshops.
- General Inquiries: The City’s Water and Sanitation branch also monitors water@capetown.gov.za for feedback regarding catchment management guidelines.
Meeting Details
- Location: Meetings are historically held at the Athlone Wastewater Treatment Works Auditorium, though some sessions may move to locations closer to the vlei.
- Participation: The forum is structured to include City officials (from CSRM and Environmental Management), NGOs (like FOZR), and local resident associations. As a collaborative platform, it is open to those who are “passionate about the Zeekoe Catchment” and willing to engage in long-term policy and oversight.
