Biological filtration
A planted regeneration zone keeps water clean naturally, with minimal or no chemicals.
A natural swimming pool uses plants and biology instead of chlorine. WETYR Pools designs off-grid, low-chemical pools that feel like swimming in a pristine spring.
Natural swimming pools pair a swimming zone with a regeneration zone of aquatic plants and biological filtration. The plants and beneficial bacteria keep the water clean, so there is little or no chlorine. Paired with solar power and efficient pumps, a natural pool can run largely off-grid, blending a true ecosystem with a beautiful place to swim.
WETYR Pools handles natural pools as a craftsman-led, design-build team. The people who plan your project are the people who build it and stand behind it, with no quality lost in the handoffs between separate companies. One team, one standard, and one point of accountability from the first conversation through long-term care.
Anyone who has swum in a clear spring, a clean lake, or a mountain stream knows the difference. The water feels different. It does not sting the eyes, it does not dry the skin, it carries no chemical smell, and it leaves you feeling rinsed rather than coated. A natural swimming pool is an engineered way to bring that experience home, into your own backyard, every day of the year.
A natural pool works the way a healthy body of water works in nature. Instead of dosing the water with chlorine, it pairs a clean swimming zone with a regeneration zone, a planted area where aquatic plants, gravel, and beneficial bacteria continuously consume nutrients and keep the water clear. The biology does the job the chemicals would otherwise do. The result is water that is genuinely clean and safe, but soft, living, and gentle in a way a conventional pool simply cannot be.
WETYR Pools designs natural pools for homeowners who want something more thoughtful than a chlorinated rectangle: people drawn to sustainability, to a chemical-free swim, and to a feature that is a living part of the landscape rather than a sterile one. It is the most ecological way to own a swimming pool, and for the right homeowner it is also the most beautiful.
A planted regeneration zone keeps water clean naturally, with minimal or no chemicals.
Solar power and high-efficiency, low-draw equipment let a natural pool run lightly on the grid or off it.
The pool becomes habitat, framed by aquatic plants that change beautifully through the seasons.
No harsh chlorine means water that is gentle for swimmers and the environment.
A natural pool is not a pond you swim in, and it is not a stagnant feature. It is a carefully balanced system with distinct parts, each doing a specific job.
This is the clean, open water you actually swim in: a defined area with the depth, the shape, and the finish of a proper pool. It is kept free of planting so it stays clear and inviting, and it can include steps, ledges, and seating like any swimming pool.
Separated from the swimming area, the regeneration zone is planted with aquatic plants in gravel beds. Water circulates slowly through it, and the plants and beneficial bacteria strip out the nutrients that would otherwise feed algae. This is the living filter at the heart of the pool.
Efficient, low-draw pumps move water between the two zones continuously. There are no harsh chemicals and no aggressive equipment, just steady, quiet circulation that keeps the whole system balanced and the water moving.
Because the regeneration zone is planted, a natural pool becomes part of the garden. The aquatic plants flower and change through the seasons, the feature attracts dragonflies and birds, and the pool reads as a designed pond you happen to swim in.
A conventional pool is an energy and chemical appliance. It consumes electricity for an oversized pump, a steady stream of chlorine and balancing chemicals, and often gas for heating. A natural pool is designed from the opposite direction, to consume as little as possible, which makes it a natural fit for off-grid and low-impact homes.
Because the biology does the filtration work, a natural pool does not need an aggressive, power-hungry pump running long hours. It uses gentle, high-efficiency, low-draw circulation. That modest energy demand is small enough to be met by solar power, which means a natural pool can run largely or entirely off-grid. Paired with solar pool heating to take the chill off the swimming season, the whole feature can operate on sunlight with very little ongoing cost.
WETYR Pools designs the energy system around your goals, whether that is simply a lower utility bill, a meaningful step toward sustainability, or a genuinely off-grid property. The natural pool, the solar power, and the efficient equipment are designed together as one system, so the finished feature matches the way you want to live.
A natural pool is a more sophisticated design than a conventional pool, because it is a managed ecosystem rather than a treated tank. Getting it right takes real expertise, and climate is a central part of that. Heat and strong sun affect plant selection, the size of the regeneration zone, water temperature, and where shade is needed. A natural pool designed without respect for its climate will struggle; one designed with it will thrive.
WETYR Pools designs each natural pool specifically for its site and conditions: the right aquatic plants, the correct ratio of swimming zone to regeneration zone, sensible depth, and thoughtful shading and placement. We size the system so it stays in balance through the warmest part of the year, and we set realistic expectations about how a natural pool looks and behaves, because it is a living feature with seasonal character, not a static blue rectangle.
If you love the idea but are not certain a fully natural pool is the right fit, there is middle ground: low-chemical and hybrid designs that lean on biological filtration while keeping a light conventional backup. We will walk you through the honest trade-offs and design the version that suits your property. As always, the project is presented as a clear, fixed, itemized proposal before any work begins.
Clear answers to the questions homeowners ask most.
Yes. A correctly designed natural pool keeps water clear and safe through biological filtration, where aquatic plants and beneficial bacteria consume the nutrients that feed algae. It is a managed, circulating ecosystem, not a stagnant pond.
They can, with the right design. Heat and strong sun affect plant selection, the size of the regeneration zone, and shading, so the design has to respect the local climate. We design each natural pool specifically for its site and conditions.
Often yes. Because the biology handles filtration, a natural pool needs only gentle, low-draw circulation, which is small enough to be powered by solar. Paired with efficient equipment and solar heating, a natural pool can run off-grid or close to it.
A true natural pool uses little or no chlorine, relying on biological filtration instead. For homeowners who want a backup, we can also design low-chemical and hybrid pools that lean on the biology while keeping a light conventional system in reserve.
It needs different maintenance, not necessarily more. Instead of dosing chemicals, care focuses on the plants, the regeneration zone, and the balance of the system. Our maintenance plans can handle that seasonal care for you.
A well-designed natural pool has moving, circulating water, which does not breed mosquitoes. It does attract welcome wildlife such as dragonflies and birds, which are signs of a healthy, balanced ecosystem.
WETYR Pools provides natural pools to homeowners nationwide, including these communities.
