Learn how to build a natural swimming pool in order to create a cooling summer retreat for your homestead.

Whether you like to practice your dolphin dives or lounge away the day on a raft, swimming is one of summer's perfect pleasures. With a minimum of materials and without an arsenal of chemicals, you can build an idyllic water oasis right in your own back yard and thwart summertime's sultry dog days.

Though fairly common in Europe, natural swimming pools (like the one pictured above in an Austrian family's backyard), are in their infancy in the United States. Ask most American swimming-pool contractors to build a backyard pool and chances are they'll roll out a long list of goods, including rebar, gunite, fiberglass, chlorine and an energy-sapping filtration system. But in recent years, a few builders and a growing number of homeowners have learned how to build pools without relying on a mass of manufactured materials and chemical additives. They've found it's possible to construct pools that are more about building with nature and blending into the natural landscape. Natural swimming pools use gravel stone and clay in place of concrete or fiberglass, and aquatic plants instead of harmful chemicals and complicated mechanical filtering systems. The plants enrich the pool with oxygen, support beneficial bacteria that consume debris and potentially harmful organisms, and give habitat to frogs, dragonflies and other water life. The result is a beautiful, ecologically diverse system that is relatively inexpensive to construct. (A natural pool can he constructed for as little as $2,000 if you do it yourself, while conventional pools can cost tens of thousands of dollars.) Natural swimming pools require no harmful chemicals, are fairly low-tech, and once established call for only a modicum of management. You won't have to drain the pool each autumn. Except for topping it off now and then, you'll fill the pool only once.

Dig It: Creating a Natural Swimming Pool by Hand

The cheapest and most ecologically sound way to build a swimming pool is simply to hollow a hole in the ground. You can make your pool as shallow or as deep as you want, but the key is to make sure the sides slope: Otherwise the soil will cave in. The ratio should be a 1-foot vertical drop for every 3 horizontal feet. "It's not a bathtub effect, but more like a soup bowl," says Tom Zingaro, partner with Denver-based Blue Lotus Designs, a pool-and pond-architecture company. One of the main reasons traditional swimming pools are constructed with a steel framework is to ensure the walls stay vertical and perpendicular to the bottom surface of the pool. Construct a pool with sloping sides and you'll eliminate the need for any steel reinforcement.

Zoning Your Pool

Reserving at least 50 percent of your pool's surface area for shallow plants, either at one end or in a ring around the sides, eliminates the need for chlorine and expensive filters and pumps. You'll want to separate the swimming area of your pool and the filtration area, or plant zone (see the illustration in the image gallery). A rim within an inch of the water's surface keeps plants in their place but allows water from the swimming area to move to the plant zone for filtering, As water passes through the fibrous root structure of the plants, bacteria concentrated on the plants' roots act as a biological filter, removing contaminants and excess nutrients in the water. Decomposer organisms, also found in the plants' root zones, consume the bacteria, effectively eliminating underwater waste buildup.

Inside the plant zone, the water should get steadily deeper, reaching a maximum depth of 18 inches near the swimming zone. The outermost 6 inches of the plant zone will be 2 to 3 inches deep, providing a home for taller aquatic plants. Submergent and floating vegetation occupy the deeper area.

Besides cleaning the water and making your pool beautiful to behold, the shallow plant zone warms the water quickly and provides habitat for frogs and many invertebrates. They'll appreciate the shallow water for breeding grounds and repay the favor by eating mosquito larvae.

Natural Pool Filtration

The water needs to circulate continuously for the plants' roots to cleanse the pool. You also may need to aerate the water so the water organisms' oxygen needs are met. (Without adequate oxygen, your pool could become stagnant, harboring odoriferous anaerobic bacteria.)

Water can be channeled from your pump into your plant zone through the use of PVC tubes. (Zingaro recommends using flexible PVC in cold climates.) In any climate, bury the tubing in the soil about 18 inches deep. Underwater aeration, which uses less energy than constructed waterfalls and circulates water more effectively, involves diffusing air at the pool's bottom. You can build your own aerator, using an air compressor (1/4-horsepower for a pool smaller than an acre) and high-strength tubing that connects to a diffuser. The diffuser (see "Pool Equipment Sources" at the end of this article), which bubbles air through the water, rests in the deepest part of the pool, where swimmers are not likely to damage it. Connect a brass manifold to the compressor to regulate the air pumped into the pool. Don Schooner at Inspired By Nature, an Ohio-based, pond-and-lake-restoration company, suggests aerating the pool four to eight hours a day: in the morning, when oxygen demand is greatest, and again in the evening. Place your aerator, pump and skimmer in a plastic container, such as a bucket or large plant container, and put a steel-mesh filter mat over the top, to keep debris out of your equipment. Expect to pay $1,000 to $1,200 for a quality underwater aeration system.

Some folks use skimmers hooked up to an additional small pump, to suck off floating undesirables. While these devices are not essential, you might want to consider purchasing one if leaves or seeds from nearby trees and shrubs are likely to litter your pool. The skimmer removes detritus that would otherwise sink and contribute to algae growth.

Installing pumps and compressors can be a tricky business because you're running electrical devices near or in water, You'll want to connect electrical hardware to your home power supply through a buried conduit. Do not run your power through an extension cord. Hire a skilled electrician who will ensure the safety of the system.

Sealing Your Natural Pool

Once you've dug the hole for the swimming pool and the plant zone, you have a couple of options, depending on your soil conditions, to make sure the pool holds water: You can apply a layer of bentonite clay to seal the soil or lay a synthetic liner. Bentonite is usually the cheaper option, averaging 35 cents per square foot. Liners can cost 25 cents to $1 per square foot, depending on their composition and weight.

Bentonite works as a glue, bonding with the soil particles and preventing pool water from seeping into the ground. Some soils may contain enough clay that simply compacting the pond bottom will enable it to hold water. Talk to local pond builders to find out for sure. But beware: Bentonite doesn't bond well with sandy soil. Particularly sandy soil can require up to 12 pounds of bentonite per square foot, as opposed to 6 pounds in clay-rich soil. Bentonite also can be troublesome when the surrounding soil is very dry. In arid climates, Zingaro recommends bentonite be applied beneath a plastic liner that is woven or textured on the bottom. This liner keeps the bentonite from shifting. In more humid climates, bentonite can be applied directly to the soil. Before treating your pool with bentonite or any other clay powder, thoroughly compact the soil. You can do this with a lawn roller or a plate compactor. Then, while wearing a mask, spread a 2- to 3-inch layer of bentonite powder along the pool sides and bottom. Pack it down with a tractor or plate compactor. Then apply another foot of quality topsoil and compact again.

If you choose a liner, select one made of ethylene propylene diene monomer rather than PVC. EPDM is a synthetic rubber twice as expensive as PVC, but it's worth the extra cost. It has protection from ultraviolet rays, and unlike PVC remains flexible in cold weather. If your soil has a lot of rocks or roots, select a 45- or 60-millimeter liner. You can use a 30-millimeter liner if your soil is very sandy and smooth, and if you and your guests aren't likely to tear holes in a liner while frolicking in the pool. Before laying your liner, compact the sod and cover it with a layer of sand or an absorbent material such as old carpeting or newspaper. Newspaper is a good option: When wet, it bonds to the liner, providing extra protection if the liner develops a small hole.

After the bentonite clay or a liner is installed, cover the bottom of the pool with 4 to 5 inches of gravel. The gravel provides a habitat for beneficial bacteria, which help biodegrade leaves or other natural materials that sink to the bottom of your pool. Make sure you use clean gravel. Fill a 5-gallon bucket with a spigot with some of the gravel you intend to use. Open the spigot and run water through the gravel. If the water comes out dirty, you need to clean the gravel (a taxing, water-wasteful process) or find another source. Expanded shell aggregates and other manufactured gravels are likely to be clean enough to use in your natural pool. In addition to lining the pool with gravel, many people opt to build cobblestone steps for access into and out of the pool. A cantilevered dock built out over the water also provides an easy way to get in and out of the pool, and helps protect the pool's sides.

To finish the edges of your pool, run a plate compactor around the perimeter. This will help with soil erosion, but it's not enough to guarantee dirt won't fall into your pool. One option is to edge the perimeter with rocks, flagstone or wood planking. Better still, plant right next to the edge and let the plants stabilize the perimeter, says Martin Mosko, principal architect with Marpa and Associates, a Boulder, Colorado-based landscaping company. Plants work not only to anchor the soil, but create a natural setting for an old-fashioned, swimming-hole effect. Mosko says if you use plants instead of stone, choose plants that thrive in wet soil or make sure the water level is at least a foot below the pool's edge so the perimeter plants don't become waterlogged.

Natural Pool Construction: Concrete Options

If you prefer a more conventional pool shape, consider construction with cement or Rastra block, a material manufactured from cement and recycled foam plastic. Less eco-friendly than gravel and stone, these systems still can reduce chemical and energy usage by using plant-based filtration systems rather than mechanical filters and chlorine to clarify the pool water.

Pouring a concrete pool can be tricky. You have to have the right mix and the right density to prevent cracking. Because of the intricacies involved in concrete pouring, Zingaro advises against do-it-yourself concrete pool construction. If you're experienced in concrete work, he offers the following tips: Use an 4-1 ratio mix of portland cement and sand, and cover the compacted soil with fiber mesh, a rubber liner, old carpeting or newspaper, to provide a stable surface for the concrete to adhere. After the concrete is poured, trowel on a 1/8-inch coat of stucco to waterproof the pool, since concrete is porous.

An alternative to concrete is Rastra block. These blocks are 10 feet long, 15 or 30 inches high, and 10 or 14 inches thick. Made of recycled polystyrene and cement, they weigh a fraction of concrete: Two people easily can set 10-foot sections into place. Kenton Knowles of Global Homes in Baldwin City, Kansas, built a 16x32-foot pool out of Rastra for about $1,600 in materials.

To build a Rastra-block pool, excavate a hole just larger than the pool's dimensions to allow for ample workspace. Most people choose to construct a pool 5 feet deep. For the bottom, either pour a concrete slab or cover the bottom with a rubber liner. Then line the bottom with gravel. Make sure to install a drain and backflow preventer. Lay one section of Rastra block along the edges of the slab, securing the Rastra to the pad with rebar. Fill the Rastra blocks' cavities with concrete. As the concrete flows from block to block, the structure is tied together. An expanding foam sealant is used between courses and at all joints to hold the blocks in place. Knowles recommends waterproofing the blocks by troweling on two coats of stucco. Backfill the space between the sides of the pool and the Rastra block with soil. You can finish the perimeter with stones laid from the top of the blocks out into the surrounding area, or you can grow plants to the edge of the blocks.

Prepare for Planting Around Your Natural Pool

Once your pool is constructed, you'll need to prepare the plant zone with 3 to 6 inches of soil. Choose your soil with care as soil can carry various contaminants. Avoid harvesting soil from areas where animal excrement is prevalent, such as in dog runs or from grazing areas. Select soil that's free of organic matter, which would rot underwater. You can have a lab test soil samples for potentially pathogenic bacteria. To find a laboratory in your area, contact your state's health department. once soil, gravel and hardware are in place, you can fill the pool. Disturb the soil as little as possible and let the pool rest for a week before installing plants. During this time, you can test your hardware to make sure it works.

Selecting Plants for Your Pool Area

Be sure to choose plants suited to your climate. Your best bet is to obtain your plants from a native-plant supplier. Check the phone book and Internet for local sources. Home and garden centers also carry more aquatic plants now that backyard ponds are growing in popularity. End-of-the-season sales can save you money. Several mail-order nurseries also specialize in water-garden plants. (See "Pool Construction and Design.")

Sedges (Carex) and rushes (Scirpus), both aquatic plants, make great emergent vegetation for your pool's perimeter. You can also consider lesser cattails (Typha angustifolia) and aquatic irises, though be sure to ask which varieties won't overcrowd other plants. Pickerel weed (Pontederia cordata), arrowhead (Sagittaria) and water primroses (Ludwigia) are all contenders for the shallowest areas of your pool. Be sure to include submergent plants such as common waterweed (Elodea) and hornwort (Ceratophyllum) for their high oxygen output.

In water 6 to 18 inches deep, plant a mix of floating, submergent and emergent plants. Water lilies (Nymphaea) adapt to any depth, so use them liberally. Floaters, such as pondweeds (Potamogeton) and common duckweed (Lemna minor), drift freely on the surface and quickly cover the surface of the plant zone.

Before you make plans to tromp off to the nearest country pond and gather up a truckload of greenery, wait! Before collecting a single plant from the wild, know the laws protecting wetlands and their plants. if you do collect, be careful to guarantee the health of the wetland by selecting only a few samples from larger populations. Consider rescuing plants from a threatened site. Perhaps a new corporate headquarter's construction is going to destroy your favorite frog hollow. Contact the company to see if it will allow you to rescue the imperiled plants and maybe a few amphibians.

Once you've purchased your plants, you can plant them in the filled pool. Stick to a plan, grouping plants according to height and type. Place your plants into the soil, anchoring them, with plenty of gravel.

How to Control Algae in Your Natural Pool

Pond owners have been battling algae the mighty green menace — for eons. Algae compete with plants for nutrients and light, but spring algae blooms often decline as soon as water lilies and other plants emerge to shade the water. Promote plant growth and deter algae by adding plants and eliminating phosphorous to maintain a lower pH (5.5 to 6.5). The easiest remedy, and the least risky to your aquatic ecosystem, is to add more plants, which will out-compete the algae for nutrients. A second option is to monitor the pool for phosphorus. Fertilizers and urine are the two major sources of this nutrient, so make sure your pool is free of nutrient-rich runoff and remind everyone to use the bathroom before swimming. You can also increase your aeration schedule to stimulate more biological activity.

Enzymes, bacteria, acids and other strange brews have been offered as magic bullets for obstinate algae. Introducing additives to your pool may be an interesting scientific experiment, but it won't necessarily improve the pool you've invested plenty of time and money in. Beware of salesmen hawking their grand variety of miracle algae cure-alls. Remember: Your pool is a dynamic, living ecosystem. Adding synthetic chemicals probably will not bring it back into balance.

Natural Pool Maintenance

Removing plant litter in spring and fall will help maintain the long life of your natural pool. Keep your water level constant, and be prepared to add water as needed. inexpensive test kits, available in garden centers, will allow you to monitor your pool's nutrient levels, alerting you to problems.

In addition to maintaining the pool's biological health, check the mechanical systems annually. Wipe diffusers with vinegar to remove deposits, check air hoses for cracks and obstructions, and examine all connections to the pumps. Given these precautions, your pool should provide you cool pleasure for years to come.

Natural Pool Protection

Do you need to be concerned about cultivating potential pathogens in your pool? While it's true aquatic plants do not remove all contaminants from the water — and pools constructed of dirt, concrete or rubber liners don't necessarily keep bacteria at bay — the probability for contracting a serious disease from your natural swimming pool is low. Dr. Michael Beach of the Centers for Disease Control and Prevention says even chlorine-treated swimming pools can fall prey to fecal coliform contamination, which is responsible for problems such as cryptosporidiosis, a parasite that can cause diarrhea and stomach cramps. Keep babies and pets out of the waters to avoid contaminating your pool with fecal coliform. If you're uncertain about your natural pool's water quality, have it tested.

I live in Upstate New York. My girlfriend and I just bought a house in Salem, NY, and we have our hearts set on building a natural swimming pool. One of our concerns as we begin the planning process of our pool is...what do we do in the winter? Aside from the obvious need to drain any water from the pump and plumbing, do we need to remove the plants from the natural pool? I would imagine that the water will freeze several feet in depth depending on the severity of the winter. Any thoughts on our concern? Thank you in advance for your replies...

My friends were always telling me about the benefits of salt water in a pool. The important benefit to me is that saltwater is way eco friendly and less corrosive to the skin. Frankly, I didn’t like monitoring my chlorine maintained pool that often, so I did something about it and looked more online for saltwater alternatives to a swimming pool around my area in Davie. Miami Pool Tech provided me with an immediate solution when I skimmed through their website. They were ready and willing to install, renovate and recheck at my convenience as soon as I got unto them. After hiring their team of pool attendants, my new saltwater pool was frequently checked and maintained crystal clear. For more of their eco-friendly installation services, look them up on

I have a spring fed natural pond with a run off babbling brook that leads down to wetlands below. I would love to be able to swim in it, but it is very murky, and has snapping turtles. Any advice on making it safe on a budget? I'm sure it would include lots of gravel, which is only 1/4 mile away, but I'm worried about snappers and snakes.

7/24/2013 3:29:40 PM

rainie.flores.7you are obviously an advertiser for your swimming pool company that pushes chemicals! This is Mother Earth News, we do not want chemicals :) The point of natural swimming pools is too avoid all the toxic chemicals getting on and in our bodies. Now that you have made your comment, go elsewhere!!

7/20/2013 3:57:34 AM

I live in Punjab Pakistan where we have 5 seasons.Mild and short winters 2 - 2.5 months. Minimum temperature never go below zero . Spring feburary to early april. Then summer hot dry spell mid april to june end . Temperatres hit 48 c degrees. Then rainy season July and August ( temp 34- 38)  and finally autumn. 

I want to put a natural pond on my  farm  covering 2500 to 3000 sq feet of area. Water to fill the pond will come from a tube well. We will pump the water from the ground, pour it in the pond and take it out to irrigate the land. Hence every week water will be recycled. 

1.Do we need to aerate the water ? If so can it be done without using a pump or electric devise.

2. Most side of the pond have gentle slope planned except one side perhaps 30 feet long where we want a sharp fall 45 degrees. Can this be done without reverting to concrete??

7/16/2013 10:24:33 AM

A very nice post with some great images! But I have a question about "Establish your plant beds around the outside perimeter to naturally filter and clean your pool", how exactly do the plant beds around the pool naturally filter and clean it?

I mean don't you need to use pool chemicals and a proper pool filter/pump like those sold at and many others? I was hoping to build my own inground swimming pool, but that's the only bit that put me off, not know if it would cost more to due to having to install a filter and pump system to keep it clean, but you are saying that the plants around the pool can do this, how?

The problem with a modern pool, is you are bathing in a toxic gas chamber... A natural pool or pond is no worse than water skiing in a lake, not much danger of contracting some disease because the water is balanced. Just do not drink it, but then again who drinks water from a public pool? The chemicals in it will wipe out your immune system. At least the lake or pond will not do that!

We do not put our faces  under water though.we have less skeeters on the pond because we have fish, dragonflies and bats. My property is fenced and i have never had a gator but always count my ducks first LOL If one is missing then Ill look for a gator! It isnt for everyone,obviously you cannot apply oils to your skin and if you do not want fish nibbling,frogs hopping and sand between your toes it isnt for you. But if we were at the beach just minutes away we would worry about sharks and jellyfish !

Do you want a swimming pool or a pond? If it's a swimming pool, I don't think there will be all that much "natural" about it. If it's a pond you want, then natural is the only way, using only nature's resources to kep it clean and wholesome. We used to jump into pools along with the frogs, bugs and other critters, and never got sick, injured, or anything else. It was probably because we had immune systems built up from just such activities, but in today's sterile society, that would not be wise, I guess!

5/15/2013 2:40:37 AM

I think it would be best to hire a professional builder or company to buld your swimming pool. It is more convenient, less time consuming, although you may pay an extra amount of money for that, in the long run, it will still save you time and money. Plus you have the assurance of a nice-looking and sturdy swimming pool. -

Around here, we call that a pond, not a swimming pool. Not everyone wants to swim with frogs, worms, leaves and other natural detritus. Not everone has the extra space required to build a swimming hole with gradually sloped sides. If you still need mechanical aeration, then you haven't gained the energy benefit of having no mechanical filtration.

We have built ourselves a swimming pond. It is 23 meters by 14 meters and 2.8 meters deep. It wasn’t complicated to build and required no specialist knowledge. I have set up an internet forum, for people who want to swap ideas about self-building and maintenance. It occurred to me that if you could get a bunch of passionate amateurs to swap their observations then you could end up with a really useful resource. A professional will build a pond and then only visit it at intervals. An amateur will be there all the time, he won't be able to leave it alone, he will notice the smallest change. I am down at our pond checking things out every day; two and three times a day if work is dull.

(will this Work) also I will be adding all kinds of water Plants for natural Oxigination of lake and a 10'W x 1000' Creek and Waterfall that dumps in to Lake While Recirclating water ( good or bad Idea)with water plants and Cat tails as well. Then I will be adding 4-6 Different Species of Trees for Shading of lake as well to provide Air filtration (keeping Bigger Particulates from entering Lake)around 7/8 of the lake and would love to have a Sandy Beach area ( good or Bad). I will be adding Solar and Wind Mills for the powering of the Pumps as well as Some sort of Filter to remove Arsinic from water that naturally Occures in Nevada any Help in this area would be wonderfull. Also The water for the Lake will be Provided from it's Own Well, also in a side note If I Run the well water through a Series of Cisterns Having one with Carbon Media Or other Media and then pump the water to the top of My Creek will that help Neutralize any Contaminants? I have 2 Black Labs as Well and would love to have Ducks and Gees Visit my lake, Do I need to add or Modify the Plants and Fish that I am Planning to have a Sustainable Enviroment? I want To Creat A Living Eco System That My Family and Friends Can Enjoy For Decades To come, There might even Be a Pontoon boat on the Lake as Well. What do you Think, Does this sound like I'm headed in the Right Direction? Oh also I want to add Hydro Electric to the Creek waterfall to Power My Shop through A Battery System. The amount of Volume I will generate is roughly 50 thousand gpm

I am looking into building a natural pool in a summer house in France. I will only be there for 6 weeks in the summer and 2 weeks in the Spring. Would it be possible within that timescale to build a pool? Could I maintain a pool over many years when i'm only there sporadically?. Also - Is there anyone building natural pools in france? Thanks

natural swimming pools could be made at every type of climate. we made this type of pools in europe and australia. For this climate - and also Arizona, Texas .... you have to use special plants. The other important thing is to make a good hydraulic. A lot of people think, that no pump is neccasary. But the warmer the water, the more important is to circulate the water through the plant filter. In canada there is a company in Montreal called "Topia" and in USA there is company in Scottsdale (Arizona) called Supreme pools. Both can help with natural pools

can you put fish in the pool? i want to build a BIG pond for my husband to fish in, but i'd also like to swim in it. we live in hawaii on lava rock; will the bentonite work? Mother responds: People regularly swim in natural ponds that have fish in them. You will have to take into account the waste from the fish in terms of the amount of plant matter that can filter and clean the water, in addition to any food you might feed the fish.

Re: Tony about snakes and such. That's an interesting point you raise. But it's not unique to natural pools. Chlorinated swimming pools often get snakes in them. We have a pool in our community that gets about one a week and even more when it rains because it is adjacent to an agricultural area and has no real effective barriers. This issue has more to do with the access to the area than with the type of pool. If this is a big concern then you'd want to build perhaps tall masonry walls around the pool or something of that nature. Of course they're usually more scared of you than you are of them.
