Quality Pond Construction & Care Services in Antioch

Building a custom pond is one of the most tangible ways to change how you experience your backyard. The sound of running water carries through the yard. Koi become part of the daily rhythm of the house. The water garden draws wildlife, supports an ecosystem, and gives the outdoor space a center that no other landscape feature provides. Pond construction in Antioch is accessible, effective, and holds up well in the local climate when the system is designed correctly.

California Aqua Pros has built custom ponds and water features across the Bay Area since 1993. Greg and Marlo Purkey founded the company on the principle that a water feature should be designed for the specific yard and the specific family, not built from a standard template. Every project begins with a site visit and a real conversation about how you use your outdoor space and what you want it to feel like. From there, we engineer the system to function over years of use before we finalize the aesthetics.

Koi pond construction is the most requested service we provide. A koi pond that holds up over time requires filtration sized to the fish load, depth calibrated to the local climate, and rock work that creates a natural edge without compromising water circulation. We are Diamond Certified contractors and hold a Master Aquascape Contractor designation, which reflects a technical standard developed through decades of specialized work in this region.

For homeowners who want the experience of moving water without the commitment of a full koi pond, pondless waterfall construction is often the right answer. The reservoir is buried underground, the surface reads as a dry streambed or rock feature between pump cycles, and no standing water is exposed. For families with young children or yards where a full pond is not practical, this delivers most of the experience at lower maintenance. We also design fountainscape installations for entry gardens, courtyards, and smaller landscape beds.

A koi pond combined with a waterfall or connecting stream is one of our most popular build configurations. The moving water oxygenates the system, reduces algae pressure, adds audible presence, and creates a design that draws the eye through the yard. These layered builds tend to become the feature the whole yard is organized around.

After construction, our pond maintenance team handles the ongoing work on a scheduled basis. Filter cleaning, water chemistry, aeration monitoring, and seasonal adjustments are all covered. Antioch summers run hot, and consistent maintenance through the warmest months is what keeps fish healthy and water clear.

Pond Construction

Every pond we build begins with your vision and the natural character of your yard. Our team designs custom koi ponds and garden ponds with native stone, aquatic plants, and a balanced ecosystem that keeps the water clear and the fish healthy. The result is a tranquil backyard sanctuary that feels like it has always belonged there.

Pond Maintenance

A healthy pond is a living ecosystem, and our maintenance program keeps yours in ecological harmony year-round. We handle seasonal cleanings, water quality, and the small adjustments that protect your koi and aquatic plants. With our team caring for the details, you get to simply enjoy the water.

Fountains & Water Features

A fountainscape brings the calming sound of moving water to a patio, entryway, or garden without the space a full pond requires. We design and install custom fountains and water features that suit the scale and style of your home. Each one is built for lasting beauty and quiet, dependable operation.

Pondless Waterfall

A pondless waterfall delivers the artistry and sound of flowing water with minimal upkeep and no open pool. Water disappears into a hidden reservoir and recirculates, so you enjoy a natural stream or waterfall feature that fits busy yards and young families. It is one of the most popular ways to bring nature into your backyard.

We renovate backyards into cohesive sanctuaries, weaving water features, native plantings, and natural stone into one balanced design.

Landscape Design

Thoughtful landscape design is the foundation of every outdoor space we create. We plan the flow, plantings, and natural materials so your yard works as a whole, with room for water features, gathering areas, and lush greenery. Our designers blend creative vision with the ecological knowledge that keeps a landscape thriving.

Our History in Antioch

Antioch sits on the southern bank of the San Joaquin River where the Delta begins to fan out toward the bay. Contra Loma Regional Park is minutes from most neighborhoods, the Antioch Bridge connects the community to the North Bay, and the Delta waterways are part of daily life for residents who fish, boat, and spend time on the water. That connection to natural waterways is something a lot of Antioch homeowners carry into how they think about their yards. A backyard pond is an extension of the same impulse.

We have served Antioch as part of our East Bay service territory for many years. The community’s proximity to Discovery Bay, where our operations are based, makes it one of the more natural areas for us to work in. Yards here tend toward the generous side, and the Delta climate creates a long outdoor season that makes year-round enjoyment of a pond realistic without much adjustment.

We also serve the neighboring area of Danville and the broader Contra Costa County corridor. If you are in Antioch and interested in adding a pond to your yard, we are close by and ready to start the conversation.

Frequently Asked Questions - Antioch Remodeling

How does the Delta climate in Antioch affect a backyard pond?

Antioch sits at the western edge of the Delta, which means summer heat combined with the occasional Delta breeze. Water temperature in a shallow pond can spike quickly during hot stretches, which stresses koi and reduces dissolved oxygen. A properly designed pond with adequate depth and continuous aeration handles those conditions well. We design for the local climate from the start.

What is the minimum depth for a koi pond in Antioch?

We recommend a minimum depth of 24 to 30 inches for a koi pond in Antioch. That depth buffer helps keep water temperatures more stable during summer heat spikes. Larger koi or higher fish loads benefit from additional depth, and we discuss the right sizing during the site visit based on how many fish you want to keep.

Can I do a pondless water feature instead of a full pond?

Yes, and this is one of the most popular options we install in Antioch yards. A pondless waterfall or stream feature delivers the sound and movement of water with no standing water exposed at the surface. The reservoir is underground, the system recirculates on a pump, and the feature can be switched on and off easily. It requires less maintenance than a koi pond and has no depth concerns for children or pets.

How long does pond construction take in Antioch?

Most residential builds take one to two weeks from excavation through final planting and fill. Larger projects with multiple waterfall tiers or extensive rock work may run two to three weeks. We provide a clear timeline at the start of every project.

What ongoing maintenance does a koi pond require?

Skimmer baskets need clearing every week or two, filter media gets rinsed monthly, and water chemistry should be checked regularly through the summer. Antioch’s heat makes consistent aeration monitoring particularly important during the hottest months. Our pond maintenance team handles all of this on a scheduled service plan so you are not managing it yourself.
