Swimming Ponds and Natural Pools in Alhambra
We build Recreational Ponds used for swimming
What is a Swim Pond?
California Waterscapes designs and builds custom swimming ponds and natural pools for clients throughout Alhambra. Also known as “recreation ponds” or “natural swimming lakes,” these large, eco-conscious ponds are tailored for both leisure and aesthetics. We can construct your pond in any size, depth, or shape you envision, every detail is customized.
Optional Upgrades For Swim Ponds
We offer a range of optional enhancements to elevate your swim pond experience:
- Additional UV sterilizing filtration
- Increased depth for swimming
- Step entries or beach-style access
- Flagstone base instead of gravel
- External pump solutions for better flow
How Are Swim Ponds Filtered?
Our filtration system mirrors traditional pools, minus the chemicals. We use an all-natural approach that keeps your water clean and balanced.
The mechanical filter (or skimmer) removes debris like dust and leaves from the pond surface.
The biological filter uses beneficial bacteria to naturally purify the water. Unlike chlorine-based pools, our method harnesses the power of nature. For larger ponds, we incorporate a wetland filter, offering powerful, sustainable filtration.
How much do Swim Ponds Cost?
The cost of swimming ponds and natural pools in Alhambra typically ranges from $50,000 to $200,000, depending on features, size, and filtration. Large-scale water features designed to resemble lakes may cost $250,000 or more.
Are Swim Ponds Cheaper Than Traditional Pools?
Yes. On a per-square-foot basis, swim ponds and natural pools are generally more affordable than conventional pools. Our natural construction methods simplify the process and reduce the need for heavy materials and intensive labor.
How We Design & Build Ponds
We focus on crafting ponds that feel like they’ve always been part of the landscape. Using natural boulders, plants, gravel, and a flexible liner, we shape each project to reflect an organic, untouched aesthetic.
Our builds include:
- Rubber liner from PondGuard Aquascape
- Curved edges framed by boulders and plantings
- Gravel or optional flagstone base
- Integrated filtration built into the pond itself, no exposed equipment
Do I need fish in my Swim Pond?
Fish enhance the health of your pond and help control algae naturally. While not mandatory, we recommend adding fish or even small minnows to support the ecosystem.
