Average Pond Construction Cost in Memphis, TN
In 2025, the average cost to build a residential pond in Memphis typically falls between:
- $15,000 – $22,000 for small to medium decorative ecosystem ponds
- $22,000 – $30,000+ for large, custom ecosystem ponds
- $30,000 – $50,000+ for premium koi ponds with filtration, lighting, and landscaping
These are general ranges. Your project cost will depend on a few key factors.
What Affects the Cost of a Pond in Memphis?
1. Size and Depth
The bigger and deeper the pond, the more excavation, materials, and filtration it needs. A small backyard water feature (6×8 feet) might cost under $7,000, while a 15×20-foot koi pond with depth for fish and aquatic plants could reach $20,000 or more.
2. Type of Pond
- Decorative/Fountain Ponds – Smaller, aesthetic, often under $10k
- Ecosystem Ponds – Natural balance of fish, plants, and filters; mid-to-high range
- Koi Ponds – Deeper, with advanced filtration; higher-end projects
3. Materials and Filtration System
Premium rock, liners, and advanced filtration systems (especially for koi ponds) increase both performance and price.
4. Landscaping & Add-ons
Want bigger waterfalls, upgraded lighting, walkways, or landscaping around your pond? These enhancements can raise the final bill by several thousand dollars.
5. Site Conditions
Hard soil, existing structures, tree roots, or grading challenges can all affect labor costs during excavation.
Why Memphis Pricing is Unique
Memphis’s warm, humid climate is ideal for backyard ponds—but there are also local considerations:
- Clay-heavy soil means extra care during excavation
- Spring and summer storms call for smart drainage planning
- Local wildlife (think raccoons and herons) may require protective features for koi ponds
That’s why working with a local expert who knows the Memphis terrain matters.
Pro Tips to Budget for Your Pond Project
- Start with a Consultation – At Memphis Water Gardens, we offer on-site consultations to give you realistic pricing and ideas for your space.
- Plan for Filtration & Future Maintenance – Don’t skimp on the filtration system—especially for koi or ecosystem ponds. It’ll save you thousands long-term.
- Add Features in Phases – If you’re on a budget, consider starting with the essentials and upgrading later—like adding a waterfall or lighting next year.
- Consider Permits & Utility Marking – Most Memphis residential pond builds don’t require permits, but utility marking is a must (and usually free via 811).
- Protect Your Investment – Ask about maintenance plans to keep your pond healthy year-round. Algae, debris, and pump issues are common but avoidable.
