Natural Swimming Pond Design Solutions in Riverside, CA

Natural swimming pond design in Riverside, CA combines recreational swimming areas with biological filtration and aquatic plant ecosystems, offering a chemical-free alternative to traditional pools for environmentally conscious homeowners.

How Do Natural Swimming Ponds Work?

Natural swimming ponds use separate swimming and regeneration zones where aquatic plants and beneficial bacteria filter water without chlorine or harsh chemicals.

The swimming zone is kept open and clean for recreation. The regeneration zone surrounds or adjoins it and is planted with water lilies, rushes, and submerged vegetation. These plants absorb nutrients and support microorganisms that break down organic waste naturally.

Water circulates between zones via pumps and gravity flow. Mechanical skimmers remove surface debris, while biological processes handle dissolved contaminants. The result is clear, safe water maintained by a balanced ecosystem rather than chemical additives.

What Plants Are Best for Filtration?

Best filtration plants include rushes, reeds, water lilies, and submerged oxygenators that absorb excess nutrients and provide habitat for beneficial microbes.

Rushes and reeds thrive in shallow marginal areas and filter nitrates from runoff. Water lilies shade the water surface, reducing algae growth by blocking sunlight. Submerged plants like hornwort and anacharis release oxygen and compete with algae for nutrients.

Plant selection depends on climate and water depth. Native species adapt best to local conditions and require less maintenance. A diverse plant mix creates a resilient ecosystem that self-regulates water quality throughout the year.

For ongoing care, homeowners can explore pond maintenance services that preserve ecosystem health and water clarity.

Can You Swim Year-Round in Riverside?

Riverside's mild winters allow extended swimming seasons, though water temperatures may require heating or seasonal use depending on personal comfort preferences.

Natural swimming ponds can be enjoyed from late spring through early fall without supplemental heating. Some owners install solar panels or heat pumps to extend the season. The pond's biological system remains active year-round, even if swimming pauses during cooler months.

Unlike chlorinated pools, natural ponds do not require winterization or chemical shutdown. Plants may go dormant, but the ecosystem continues to function at a slower pace, ready to ramp up again when temperatures rise.

What Zoning and Permitting Apply in Riverside?

Riverside County requires building permits for swimming ponds, including site plans, setback compliance, and safety features such as barriers or fencing to meet local codes.

Permit applications typically include pond dimensions, depth specifications, and filtration system details. Setbacks from property lines and structures must be observed. Safety barriers prevent unsupervised access and meet pool safety ordinances, even for natural ponds used for recreation.

Working with experienced designers familiar with Riverside regulations streamlines the approval process and ensures your swimming pond meets all legal and safety requirements from the start.

Columbia Water Gardens designs natural swimming ponds that blend recreation with sustainable water management. Our team handles permitting, construction, and planting to create a beautiful, chemical-free swimming experience. Request your consultation by calling 888-713-7771.

It’s that time of year for Spring Cleaning again! Every year our staff at Columbia Water Gardens goes to work in the Spring cleaning ponds and waterfalls. Why do we choose to do this in early Spring? There are many great reasons, but overall, we have found that performing a spring cleaning this time of year has been met with great success. Here’s what’s happening in your pond right now. The biology is very slow due to the cold water. That means all the sludge and winter decomposition from leaves and other organic matter isn’t being consumed by beneficial bacteria. This sludge is a food source for algae. The kind of algae that creates “pea soup” water conditions and string algae. Algae is also less active in cold water – just like your ecosystem. Large plants are not consuming nutrient, algae (a plant) is not consuming nutrient, it’s all very quiet. Then, like it always happens every year, we have a couple of cold snaps and spring weather is on us in Southern California. This happens like clockwork somewhere in the middle of February. This spring weather warms up your pond and wakes up your ecosystem fast. Your ecosystem is hungry, and the more nutrient there is in the pond, the faster your plants grow. All of them, including algae. So, why do we clean the ponds before this happens? It’s simple. Cleaning the pond removes the food source for the algae, thereby starving it out. Here’s how this happens… As the larger plants like water lilies and other plants wake up for the spring they are hungry with a larger appetite than algae, and they consume the tiny bit of nutrient that’s left after the cleaning, thereby eating more food than algae can. This is great for your pond’s health, the entire ecosystem, and of course your koi. Maintaining optimum water quality this time of year gives you the upper hand for the rest of the year. Finally, deferred maintenance creates a greater problem, it costs more to clean, and puts your pets at risk. And if your pond was cleaned since July of last year, it still needs a spring cleaning. Getting in the habit of having us clean your pond in the spring is the best thing you can do for your pond. Here’s what we do: Columbia Water Gardens will provide the following 14 point service: 1. Drain water feature 2. Set up quarantine for your fish (if applicable) 3. Drain, Rinse & Pond Refill 4. Pond Sludge Rinsing and Draining 5. Pressure wash rocks & gravel from the waterline up 6.

We charge $150.00 per man, per hour, for cleanings with a 2 person crew. Cleaning time includes setup and cleanup. This covers overhead costs like equipment, labor, tools, etc. Bare minimum for pond cleanout, pondless waterfall cleaning or fountain cleaning if 2 hours or less is $600.00. Acid baths require muriatic acid to try and clean up hard water or overly chlorinated stains on rock. Acid baths are not a guarantee solution, but in some cases help and are an additional charge. Please consider the Ion Gen to eliminate string algae and the Automatic Dosing System. These two products combined with proper filtration provide stunning results.
