Introduction

In recent years, natural swimming pools have gained popularity as an eco friendly alternative to traditional swimming pools. These pools use natural filtration systems, often incorporating aquatic plants, to maintain clean and healthy water without the need for chemicals. Building a natural swimming pool can be a rewarding DIY project, but it requires careful planning and execution. Here's a comprehensive guide on how to build a natural swimming pool, covering everything from site selection to maintenance.

Benefits of Natural Swimming Pools

Natural swimming pools offer several advantages over traditional pools:

• Eco Friendly: They eliminate the need for chlorine and other chemicals, making them safer for both humans and the environment.
• Cost Effective: While the initial setup might be costly, long term maintenance costs are significantly lower.
• Aesthetic Appeal: The integration of plants and natural surroundings creates a beautiful landscape feature.
• Health Benefits: Swimming in chemical free water can be healthier for skin and hair.

Steps to Build a Natural Swimming Pool

1. Site Selection and Design

When choosing a site for your natural swimming pool, consider the following factors:

• Leaf Fall: Avoid areas under trees to prevent excessive leaf litter in the pool.
• Shading: Ensure the pool receives adequate sunlight to maintain water temperature and plant health.
• Drainage: Plan the pool's location to prevent runoff from the surrounding area entering the pool.

Design your pool with a simple shape, such as a box or oval, to facilitate construction and maintenance. Consider the size and depth based on your needs and available space.

2. Excavation

Excavate the site according to your design, ensuring the sides slope to prevent soil collapse. A common ratio is a 1-foot vertical drop for every 3 horizontal feet. This approach eliminates the need for steel reinforcement.

3. Soil Preparation and Liner Installation

After excavation, prepare the soil by laying a layer of clay or gravel to serve as a base for waterproofing. This layer should be about 30 cm thick and cover the entire bottom of the pool.

Install a liner to ensure the pool is leak free. This can be a rubber liner or a concrete slab, depending on your preference and budget.

4. Filtration System

Natural swimming pools rely on biological filtration, which involves using aquatic plants to clean the water. Allocate at least 50% of the pool's surface area for a plant zone. This area should be separated from the swimming zone by a rim that allows water to flow into the plant zone for filtration.

5. Plant Selection and Planting

Choose plants that are suitable for water purification, such as cattails, water lilies, and submerged aquatic vegetation. These plants help remove contaminants and excess nutrients from the water.

Prepare the plant zone with a layer of soil, ensuring it is free from contaminants. Plant the selected aquatic plants in this zone once the pool is filled.

6. Construction and Sealing

If using a Rastra block or similar material for the pool walls, secure them with rebar and fill the cavities with concrete. Use expanding foam sealant between courses and at joints to ensure watertightness.

For a more natural look, finish the perimeter with stones or allow plants to grow up to the edge of the pool.

7. Final Touches and Maintenance

Once the pool is constructed, fill it with water and allow it to settle for a few days before planting. Regular maintenance involves monitoring water quality, pruning plants, and ensuring the filtration system is functioning properly.

Tips for Building a DIY Natural Pool

• Keep It Simple: Avoid complex designs that might complicate construction and maintenance.
• Use Natural Materials: Opt for materials like gravel and clay instead of concrete when possible.
• Avoid Deep Pools: Shallow pools are easier to maintain and safer.
• Choose the Right Plants: Select plants that are effective for water purification and suitable for your climate.

Conclusion

Building a natural swimming pool is a rewarding project that combines eco friendliness with aesthetic appeal. By following these steps and tips, you can create a beautiful and sustainable swimming environment in your backyard. Whether you're looking to reduce your environmental footprint or simply enjoy a healthier swimming experience, natural swimming pools offer a compelling alternative to traditional pools.
