Integrated Water Management

Integrated Water Management: Short-Term Protection & Long-Term Resilience

At Vetiver TT EES Ltd, we recognize that effective water management is the cornerstone of any successful stabilization project. While the Vetiver System (VS) provides a robust, long-term biological solution, managing high-velocity surface runoff during the critical establishment phase is essential to protecting your investment.

Comprehensive Drainage Solutions

We design and implement integrated water management strategies that combine traditional “grey” infrastructure with “green” bio-engineering. Our approach ensures site stability from day one through a phased implementation:

1. Short-Term & Temporary Measures

During the initial growth phase of the Vetiver System, we deploy temporary controls to prevent soil loss during intense rainfall:

• Lined Surface Channels: Utilizing plastic or geotextile linings to safely convey water.
• Erosion Blankets: Protecting exposed soil surfaces until vegetation takes hold.
• Silt Fencing: Managing sediment transport during active construction.

2. Permanent Infrastructure Design

For long-term site resilience, we integrate the Vetiver System with permanent drainage features, including:

• Naturalized Drains: Grass or gravel-lined channels that blend with the landscape.
• French Drains: Subterranean systems designed for subsurface water management and hydrostatic pressure relief.
• Hybrid Structures: Combining VS with gabion rock baskets, concrete drainage, and strategic reforestation with native species.

The Hydrologic Impact of the Vetiver System

Once established, the Vetiver System functions as a dynamic water management tool. By planting hedgerows on a precise contour, the system delivers two primary hydrologic benefits:

• Horizontal Flow Spreading: Concentrated runoff is “broken up” and spread horizontally across the slope, preventing the formation of erosive gullies.
• Infiltration & Recharge: By slowing water to a manageable velocity, the VS promotes natural groundwater recharge. This keeps the landscape fertile during dry seasons and significantly reduces the volume of water contributing to downstream flooding.
