Important Factors: Cost To Build A Pond

Important Factors: Cost To Build A Pond






Digging a pond needs vast planning as many professional activities are involved with it. There is no way to ignore a single thing to get your desired pond. Let’s have a look at which things affect pond building costs.


The pond building cost will vary depending on your geographical area. Building a pond in a rural area can be less expensive than in an urban area. Moreover, if the land is flat, it also costs less than a terrain-type land. So you can understand how the pond’s constructional location affects the cost. Here is a short list of pond building costs in the 7 most common USA regions. 

  • Chicago: $2,300
  • Los Angeles: $3,800
  • Texas:  $5,160
  • Boston: $3,200
  • Kentucky: $3,500 
  • Denver: $2,600
  • Miami: $3,100
Region Estimated Cost (USD) Notes
Northeast $15,000 – $40,000 Higher labor costs and rockier soil can increase excavation costs.
Southeast $12,000 – $35,000 Generally softer soil but might require more work on water control.
Midwest $10,000 – $30,000 Soil conditions can vary; generally moderate labor costs.
Southwest $11,000 – $33,000 Abundant rainfall can reduce water-sourcing costs but might require more work on drainage.
West $14,000 – $38,000 Varied terrain and soil conditions; water sourcing can be more expensive in drier areas.
Northwest $13,000 – $37,000 Abundant rainfall can reduce water-sourcing costs but might require more work on drainage.

Soil Type

The cost also varies according to the soil type of the land. Because if the land is flat and the soil is loose, it takes less time and energy to dig the pond. But if your selected land is full of rocky terrain and surrounded by trees, it is tough to dig the pond. If your land has clay-like soil, you have to spend around $200 to $1,200, and for loose soil $150 to $1000 for digging a pond.


Another essential factor is its size. For example, if you want to build a pond on ½ acre of land, then it should be 6-10 feet deep for a swimming pond. You can go for a more shallow pond for other purposes. The ½ acre land means 21780 square feet, and it costs you roughly $2800 to install a pond.


Excavation is the essential step in constructing a pond, and its cost is counted per cubic yard. You have to spend $1.50 to $3.50 per cubic yard to excavate your pond, and here per cubic yard is measured by multiplying the length, width, and depth. 

However, some excavator companies have a per-hour charging rate. Because some types of ponds need some technical grading equipment to dig the pond. If you spend per hour, it may cost you around $1,940.

Retention/Detention Pond $3,000 – $7,000 $1,500 – $3,500
Farm Pond (For Livestock) $2,500 – $5,000 $1,250 – $2,500

Swimming Pond Cost

Swimming Pond Cost

You can compare it to a swimming pool. So this type of pond should be more profound than other ponds. You have to spend at least $50 per square foot to build a swimming pond. Fortunately, this type of pond is easy and simple to maintain. So once you build the pond, you need less cost for its maintenance.

Manmade Pond Cost

Manmade Pond Cost

The manmade ponds are built according to the homeowners’ preference. So there are no specific criteria that reduce its construction cost. This type of pond costs around $100 and $5,000.

Garden Pond Cost

Garden Pond Cost

If you like to cultivate different types of vegetables in your backyard garden, then a garden pond is very useful to irritate the plants. The garden pond is small and costs you less, as you can do the work yourself. You have to cost $150 for small liner ponds and $1,000 or more for large ponds. 

Koi Pond Cost

Koi is one of the famous fish that can live in pond water. So many people cultivate them in a pond. The average cost to build a koi pond is around $5,000 and $6,000. This pond should be a minimum of 3 feet deep; otherwise, the fish won’t live there. 

However, in winter it requires a vast setup like a heating system, generator, filter, etc. As the koi fish can’t tolerate cold weather. You have to invest huge bucks in installing all those things and maintaining them.

Materials-Based Pond Building Cost

Materials-Based Pond Building Cost

You need different types of materials to build a pond. Some common pond-building materials are underlayment, pond liners, bricks/heavy rocks, tubes, pipes, fittings, pumps, filters, skimmers, and aerators. Here, the skimmer and aerator are optional.

Concrete Pond Cost

Concrete Pond Cost

If you want to dig the pond for long-term use, it’s better to use brick or concrete to make it more durable. But as bricks or rocks are very expensive, it costs you approximately $60 to $120 per square foot.

Pond Liners Cost

Pond Liners Cost

You’ll find different kinds of pond liners based on their quality, and the price will vary for this. An average size 12×12 pond liner costs you around $1,000, including material and labor charges. The minimum cost of the pond liner is around $250, whereas the maximum cost is around $6,500.

Some Unique Ideas And Recommendations:

Unique Ideas:

  1. Multi-Functional Pond Design: Think of designing a pond that serves multiple purposes. For example, a section could be dedicated to aquaculture (like growing fish or aquatic plants), while another part could be more recreational (for swimming or paddle boating).
  2. Natural Filtration: Implement a natural filtration system using plants like water lilies, cattails, and water lettuce to keep the water clean, reducing the need for expensive filtration systems.
  3. Integrated Ecosystem: Consider introducing species that benefit each other. For instance, ducks can help control certain pests, while their droppings can provide nutrition for aquatic plants.
  4. Underwater Garden: Create an underwater garden with various aquatic plants. This not only beautifies the pond but also supports aquatic life by providing shelter and food.
  5. Solar-Powered Features: Utilize solar panels to power pond features like aerators, lights, or fountains. This can cut down on long-term energy costs.
  6. Island Creation: If the pond depth and structure allow, consider creating a small island in the middle. This can serve as a unique landscaping feature or even a picnic spot.
  7. Rainwater Harvesting: Integrate a rainwater harvesting system that directs runoff water to the pond, aiding in keeping it filled, especially in drier areas.

Recommendations for Cost Efficiency:

  1. Local Materials: Use locally sourced materials whenever possible. Transporting materials from far away can significantly increase costs.
  2. DIY Aspects: While certain aspects of pond creation should be left to professionals (like excavation), there might be elements, like planting or setting up basic fountains, that you can do yourself to save on labor costs.
  3. Periodic Maintenance: Regularly maintaining the pond can avoid costly repairs in the future. This includes checking for liner damage, ensuring equipment is functioning properly, and monitoring water quality.
  4. Consultation: Before beginning the construction, consult with multiple pond construction specialists. They might offer differing quotes or suggest more cost-effective methods of achieving your vision.
  5. Natural Slopes: If your property has a natural slope, it can be leveraged for the pond’s design, potentially reducing the amount of excavation required.
  6. Pre-existing Water Sources: If there’s already a natural water source on your property, like a stream, consider integrating it into the pond design to reduce the costs of filling the pond.
  7. Comprehensive Planning: Ensure you have a detailed plan before starting. Making changes midway can inflate costs significantly.
