What is a Natural Swimming Pool?
A natural swimming pool, also known as a natural swimming pond or organic pool, is a type of pool that uses plants and biological filtration instead of traditional chemicals to keep the water clean. These pools are designed to mimic natural bodies of water and provide swimmers with an eco-friendly and chemical-free swimming experience.
Key Features and Components
Natural swimming pools consist of three main zones: the plant zone, regeneration zone, and swimming area.
- Plant Zone
- The plant zone is where aquatic plants are strategically placed to help filter the water naturally.
- These plants absorb excess nutrients from the water, preventing algae growth and keeping the water clear.
-
Examples of common aquatic plants used in natural swimming pools include water lilies, marginal plants (plants that grow at the edge of shallow waters), submerged underwater plants, and floating plants.
-
Regeneration Zone
- The regeneration zone acts as a built-in biological filter area.
- It contains gravel or other porous materials that provide surface area for beneficial bacteria to grow.
-
These bacteria help break down organic matter in the water through aerobic digestion processes.
-
Swimming Area
- The swimming area is where individuals can enjoy crystal-clear water without harmful chemicals like chlorine.
- This area should be deep enough for diving but also include shallower areas for lounging or children’s play.
Benefits of Natural Swimming Pools
There are numerous benefits associated with opting for a natural swimming pool over conventional chlorinated pools:




- Chemical-Free Experience: Natural pools eliminate exposure to chlorine which can cause skin irritation and respiratory problems in some people.
- Support Biodiversity: By using native species in your plant selection process you’re creating habitats suitable for local wildlife populations such as birds frogs etc…
- Lower Maintenance Costs: While initial construction costs may be higher than traditional pools,
natural ponds typically have lower long-term maintenance expenses. - Environmentally Friendly: Natural swimming pools use natural filtration systems, reducing the environmental impact associated with conventional pool chemicals and water treatments.
How Does a Natural Swimming Pool Work?
A natural swimming pool relies on circulation and filtration systems that work in harmony with nature to maintain clean and healthy water for swimmers.
Circulation and Filtration System
- Role of Plants in Water Purification
- The plants in the plant zone act as natural filters by absorbing nutrients from the water, depriving algae of their food source.
-
The roots of these plants provide surface area for beneficial bacteria to grow, further aiding in water purification.
-
Use of Beneficial Bacteria
- Beneficial bacteria play a crucial role in breaking down organic matter through aerobic digestion processes within the regeneration zone.
- These bacteria convert harmful substances into less toxic compounds, contributing to overall water quality.
Maintenance Requirements
To ensure optimal functioning of a natural swimming pool, regular monitoring and maintenance are essential:
-
Regular Monitoring of Water Quality
- It is important to regularly test pH levels and adjust them accordingly using environmentally friendly products if needed.
- Maintaining proper pH levels ensures healthy aquatic life while preventing growth problems such as algae blooms or murky waters.
-
Cleaning and Pruning Plants
- Plant care involves periodic cleaning, pruning dead leaves & stems removing excess debris etc… This helps keep your pond looking its best while also optimizing nutrient uptake efficiency by plants themselves leading ultimately cleaner clearer H20s!
-
Managing Algae Growth
- Although aquatic plants help control algae growth naturally,
excessive algae can still occur especially during warmer months or when nutrient levels are unbalanced.. - In these cases,a range effective solutions exist including algaecides mechanical removal backwashing adjusting nutrient ratios lighting modifications…
- Although aquatic plants help control algae growth naturally,

Designing and building a natural swimming pool requires careful planning to ensure the pool integrates well with its surroundings and functions efficiently.
Site Selection and Preparation
-
Sunlight Exposure
- Choose a location that receives adequate sunlight for optimal plant growth.
- This helps create an ecosystem where plants can thrive while providing shade for swimmers during hot summer days.
-
Soil Conditions
- Conduct soil tests to determine if any amendments or modifications are necessary prior to construction.
-
Soil composition affects water quality, plant health, and overall stability of the pool structure.
-
Size and Shape Considerations
- Determine the appropriate size and shape based on available space requirements as well as personal preferences.
- Natural swimming pools can be designed in various shapes such as rectangular, kidney-shaped, or free-form depending on individual aesthetic choices.
Construction Process
Building a natural swimming pool involves several key steps:
- Excavation and Shaping
- The first step is excavation where the desired shape is carved out of the ground using heavy machinery like excavators or bobcats..
-
It’s important to remove all rocks roots other debris before lining your hole with geotextile fabric & underlay materials such rubber liners PVC etc…
-
Installation of Liner or Concrete
- After excavation,
the next step depends on whether you’re opting for a liner-based system (using flexible rubber liners)
or concrete construction where walls floors formed by pouring cement into pre-set forms….
- After excavation,
3.Building Plant And Regeneration Zones




The plant zone should contain varying depths (for different types of aquatic plants),
while regeneration zones should have gravel beds porous substrate supporting beneficial bacteria growth…
4.Choosing Appropriate Plants And Aquatic Life
When selecting aquatic life it’s crucial choose species native your area this ensures they’ll adapt successfully their new environment without posing threat local ecosystem.
Maintenance and Care Tips for Natural Swimming Pools
To keep your natural swimming pool in top condition, proper maintenance is key.
Water Quality Management
