Designing a Natural Swimming Pool

Creating a natural swimming pool (NSP) is an innovative way to combine the joys of swimming with the beauty of nature. Unlike traditional pools that use chemicals for sanitation, natural swimming pools utilize biological processes to keep the water clean and clear. They offer an eco-friendly alternative, providing a serene retreat that blends seamlessly with the surrounding landscape. In this comprehensive guide, we’ll explore the essential elements of designing a natural swimming pool, from planning and construction to maintenance and landscaping.


Understanding Natural Swimming Pools

What is a Natural Swimming Pool?

  • Definition: A natural swimming pool is a swimming pool that uses plants and natural filtration systems to purify water without the use of harmful chemicals.
  • Components: NSPs typically consist of two zones: a swimming area and a regeneration area filled with aquatic plants that filter and purify the water.

Benefits of Natural Swimming Pools

  • Eco-Friendly: NSPs reduce the use of chemicals, making them safer for the environment and for swimmers.
  • Aesthetic Appeal: They provide a beautiful, natural-looking landscape that enhances the overall environment of your backyard.
  • Biodiversity: NSPs promote biodiversity by creating habitats for various plants and animals, contributing to a healthier ecosystem.

Common Misconceptions

  • Maintenance: Many people believe that natural swimming pools require more maintenance than traditional pools. In reality, with proper design and setup, NSPs can be quite low-maintenance.
  • Water Clarity: Some think that the water in NSPs can be murky or uninviting. However, with the right plants and filtration systems, NSPs can maintain crystal-clear water.

Planning Your Natural Swimming Pool

Assessing Your Space

  • Location: Choose a location that receives adequate sunlight while ensuring some shade is available for plant growth.
  • Size and Shape: Determine the desired size and shape of your pool based on the available space and intended use (e.g., recreational swimming, relaxation, wildlife attraction).
  • Soil Type: Assess the soil type and drainage capabilities, as this will affect the design and construction of your NSP.

Setting a Budget

  • Cost Estimates: Factor in the costs of excavation, materials, plants, and installation. Natural swimming pools can vary widely in price based on size and complexity.
  • Long-term Savings: Consider potential savings on chemicals and maintenance costs when planning your budget.

Researching Local Regulations

  • Building Codes: Check local building codes and regulations regarding the construction of swimming pools, particularly natural pools, as there may be specific requirements.
  • Permits: Determine if permits are necessary for your project and ensure compliance with local guidelines.

Designing Your Natural Swimming Pool

Choosing the Right Design

  • Types of Pools: Decide between a hybrid pool (part traditional, part natural) or a fully natural swimming pool. Each has its own advantages and aesthetics.
  • Shape and Depth: Design a shape that complements your landscape and provides varying depths for different swimming experiences.

Selecting Filtration and Circulation Systems

  • Biological Filtration: Implement a biological filtration system that utilizes plants and microorganisms to cleanse the water.
  • Water Circulation: Ensure adequate water circulation through the pool to maintain clarity and support the filtration process. This can be achieved through pumps or gravity-fed systems.

Plant Selection

  • Aquatic Plants: Choose a mix of submerged, floating, and emergent plants that will thrive in your climate and support water filtration. Popular choices include:
  • Submerged Plants: Hornwort, Elodea
  • Floating Plants: Water lilies, Duckweed
  • Emergent Plants: Cattails, Reeds
  • Aesthetic Plants: Incorporate plants that enhance the visual appeal of your pool and create a natural oasis, such as ornamental grasses and flowering plants.

Constructing Your Natural Swimming Pool

Site Preparation

  • Excavation: Begin by excavating the area to create the desired shape and depth. Be sure to create a separate regeneration zone for plants.
  • Liner Installation: Use a high-quality, durable liner to prevent water loss and support the structure of the pool.

Building the Regeneration Zone

  • Layering: Create a layered substrate with gravel and sand to support plant growth and biological filtration.
  • Planting: Install your chosen aquatic plants in the regeneration zone, ensuring proper spacing and depth.

Installing Water Circulation Systems

  • Pumps and Filters: Install pumps and filters as needed to maintain water circulation and quality.
  • Natural Features: Consider adding waterfalls or streams to enhance water movement and aeration.

Maintaining Your Natural Swimming Pool

Regular Maintenance Tasks

  • Cleaning: Regularly remove debris such as leaves and algae from the swimming area and regeneration zone.
  • Plant Care: Monitor the health of aquatic plants and trim or replace them as necessary to ensure effective filtration.

Water Quality Management

  • Testing: Test water quality periodically for pH, nutrient levels, and clarity. This will help you determine if adjustments are needed.
  • Balancing Nutrients: Add beneficial bacteria or enzymes to support biological filtration and maintain clear water.

Seasonal Considerations

  • Winterization: In colder climates, take steps to winterize your pool, such as removing plants and lowering the water level.
  • Spring Cleaning: In spring, clean the pool and rejuvenate plants to prepare for the swimming season.

Enhancing Your Natural Swimming Pool Experience

Creating a Relaxing Environment

  • Landscaping: Landscape the surrounding area with native plants, trees, and shrubs to create a serene atmosphere.
  • Outdoor Living Space: Consider adding seating, fire pits, or outdoor kitchens to enhance the overall enjoyment of your natural swimming pool.

Safety Features

  • Fencing: Install appropriate fencing around the pool to ensure safety, particularly if children or pets are present.
  • Non-slip Surfaces: Ensure walkways and surrounding areas have non-slip surfaces to prevent accidents.

Conclusion

Designing a natural swimming pool offers a unique opportunity to create a beautiful and eco-friendly oasis in your backyard. By carefully planning, designing, and maintaining your NSP, you can enjoy a sustainable swimming experience that not only enhances your outdoor space but also supports local ecosystems. With a little creativity and effort, your natural swimming pool can become a beloved retreat for family and friends, providing joy and relaxation for years to come.
