Walipini Water Management System
A Sustainable Approach to Underground Growing Structures
VIDEO DEMONSTRATION
Innovative Waterproofing Strategy
Our redesigned system eliminates microplastics while maintaining full functionality:
- Natural bentonite clay liner (5-8mm) as primary barrier
- Compacted clay layer (15+ cm) as secondary barrier
- Self-sealing technology with 75+ year lifespan
- Extremely low permeability (10^-9 cm/s)

Natural Protection System
SYSTEM LAYER VIEW
Our coir fiber protection layer offers multiple benefits:
- 100% natural coconut fiber mat (500+ g/m²)
- Protects bentonite membrane from damage
- Allows water passage to drainage system
- Naturally antimicrobial properties
- Made from renewable waste resources
Advanced Drainage System
Our PEX-based system minimizes microplastic impact:
- PEX perforated pipes with coconut fiber wrapping
- 5-10 times less microplastic shedding than HDPE
- Superior flexibility for soil movement
- Excellent freeze-thaw resistance for Danish climate
- Two-stage microplastic control system

FILTRATION PROCESS
Multi-stage filtration for hydroponic water:
- Primary Filter: Coconut fiber filter (20-30μm)
- Secondary Filter: Optimized soil matrix in vegetable sacks
- Research confirms soil can filter 80-99% of microplastics
- Enhanced with biochar and mycorrhizal fungi
- Complete protection cascade from source to harvest
