A natural swimming pond works by using biological filtration and aquatic plants to maintain clean, clear water without chemicals. Natural swimming ponds typically have a swimming area and a regeneration zone filled with gravel and plants that filter impurities and absorb excess nutrients.
Water is circulated through these zones using pumps or gravity, allowing beneficial bacteria to break down organic matter and prevent algae growth. The plants oxygenate the water while their roots provide habitat for microorganisms that help purify it. A well-designed system maintains a natural balance, reducing maintenance while keeping the water safe for swimming.
