Innovations in Wetland Management: Revitalizing Zandvlei with Weed Harvesters

Zandvlei, a wetland region near Cape Town, is set to undergo a significant transformation with the arrival of a specialized weed harvester by November 2023. This marks the beginning of a new era in wetland management, as three vessels are set to be delivered by 2025. Rietvlei is scheduled for a weed harvester delivery in February 2024, and a second vessel for Zandvlei is slated for the 2024/25 financial year.

Weed Harvesters Improving Water Quality and Navigation in Wetlands

These specialized machines, which operate like boats with underwater blades, cut and collect aquatic plants, improving water quality and navigation in the wetlands. In Zandvlei, the harvester will target pondweeds and remove algae build-up in the marina, ultimately enhancing the environmental health of the wetland and boosting the local leisure economy around the vlei.

Mayor of Cape Town Visits Paarden Island Factory

During his visit to the Paarden Island factory, Mayor Geordin Hill-Lewis expressed his enthusiasm for the project’s progress. The vessel is on track for a November debut on Zandvlei’s waters, with the hull currently being welded and construction commencing shortly. The mayor has high hopes for the future of wetland management in Cape Town, describing a vision of “cleaner, environmentally healthy waterways” with the best days for local vleis ahead.

Warranty and Maintenance Service Plan

The new weed harvester for Zandvlei comes with a warranty of at least 24 months, and the maintenance service plan covers 2,000 working hours, including all services and routine maintenance costs, labor costs, and parts. The City’s Fleet Management Department is closely monitoring the project to ensure timely delivery, conducting regular site inspections and keeping a close eye on all aspects of the project.

Combining Mechanical and Manual Weed Removal

While mechanical weed harvesters will play a significant role in improving the wetlands’ environmental health, the City’s Environmental Management Department also utilizes Expanded Public Work Programme teams for manual weed removal when necessary. However, this manual labor is subject to water quality and safety constraints.

Community Engagement and Collaboration

The City’s Deputy Mayor and Mayoral Committee Member for Spatial Planning and Environment, Alderman Eddie Andrews, expressed his gratitude to the local residents and Zandvlei Protected Area Advisory Committee for their continuous support. In November last year, the City of Cape Town earned the prestigious Wetland City accreditation, recognizing the exceptional measures taken in protecting Cape Town’s wetlands and ensuring their benefits for residents.

Alderman Andrews emphasized the importance of community engagement and collaboration, stating that the City is “always looking for innovative plans to resolve challenges, maintain, restore, and preserve our wetlands.” The arrival of the weed harvester in Zandvlei and subsequent deliveries to Rietvlei and other areas represent a significant step forward in achieving this vision. These state-of-the-art vessels promise to not only enhance the environmental health of the region but also create new opportunities for leisure and economic growth for local communities.
