Project Description
This tea stall is designed to be portable, sustainable, and adaptable, making it functional both on land and water. Built with traditional materials like bamboo, jute, and clay, it blends cultural authenticity with modern sustainability.
• A feature of this stall is its rainwater harvesting system. The sloped tin roof channels rainwater into a filtration unit made of gravel, sand, and charcoal. The purified water is then stored in a clay tank beneath the counter, providing a self-sufficient water source for making tea and washing utensils.
• Additionally, the stall incorporates a gray water treatment system.Wastewater from washing cups and dishes passes through a bio-filtration unit with sand, gravel, and aquatic plants, which naturally clean the water. This treated water can be reused for cleaning or watering plants, reducing water waste.
• This tea stall unique is its ability to float during floods. The base is designed with buoyant bamboo rafts or recycled plastic barrels, allowing it to stay operational even in waterlogged areas. This makes it a resilient business model, especially in flood-prone regions.
• Designed for easy dismantling and reassembly, the stall can be transported to different locations as needed. It serves not just as a tea shop but also as a symbol of sustainability, combining traditional craftsmanship with eco- friendly innovation to create a self-sustaining, climate-resilient business.
