Quality Pond Construction & Care Services in Concord
A pond changes how a Concord backyard gets used through the long inland summer. Water moving over stone cools the air near the patio, and the yard becomes somewhere to sit in the evening rather than somewhere to look at through a window. That shift matters more here than in the cooler parts of the East Bay.
California Aqua Pros has designed and built custom ponds and water features across the Bay Area since 1993. Greg and Marlo Purkey founded the company on the idea that a water feature should look like it belongs to the site rather than like it was dropped into it. Every project starts with a visit to the property and a conversation about how the family actually uses the space.
Concord summers regularly push past ninety degrees, and that heat is the single biggest factor in how we engineer a koi pond here. Depth protects fish when surface temperatures climb, filtration has to be sized for the higher biological load that warm water creates, and shade from planting or a well-placed boulder keeps the water column stable. We are Diamond Certified and hold a Master Aquascape Contractor designation, both grounded in decades of building in exactly these conditions.
The heavy clay soil common through the Ygnacio Valley and the older neighborhoods near Todos Santos Plaza is the other consideration. We build with flexible EPDM liner rather than rigid fiberglass shells, because clay moves seasonally and a rigid shell eventually cracks against it. Homeowners who want moving water without managing a fish population often choose pondless waterfall construction, where the reservoir sits underground and the surface reads as a dry streambed between cycles.
Once a pond is in, keeping it healthy is straightforward with the right support. Our pond maintenance service covers seasonal cleanouts and water quality for clients who would rather enjoy the feature than manage it. You can see finished work across the region on our featured projects page.

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.
Backyard Renovation
Imagine stepping outside into an outdoor living space designed around your family and the way you want to spend your time. We renovate backyards into cohesive sanctuaries, weaving water features, native plantings, and natural stone into one balanced design. Artistry and technical precision guide every project from concept to completion.
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 Concord
Concord is the largest city in Contra Costa County, and its housing stock reflects the decades it grew through. Post-war tract neighborhoods sit alongside larger-lot development in the hills toward Crystyl Ranch and the Ygnacio Valley corridor. Todos Santos Plaza anchors a downtown that has kept a real center of gravity, and the Mount Diablo foothills rise directly to the east.
That range of lot sizes and eras shapes how we approach a design here. An older tract yard with a flat rectangle of lawn calls for a different pond than a sloped hillside parcel with established oaks. Concord homeowners tend to be practical about what they want and clear about how they plan to use the yard, which fits the way we work.
We also build throughout the neighboring communities of Clayton and Walnut Creek. If you are in Concord and thinking about a pond or water feature, we would like to hear what you have in mind.
Frequently Asked Questions - Concord Remodeling
How does Concord's summer heat affect a koi pond?
Concord regularly sees stretches above ninety degrees, and warm water holds less dissolved oxygen while raising the biological load on the filter. We address this with depth, so there is a cooler layer for fish to hold in, with filtration sized above the minimum, and with circulation that keeps the whole column moving. Shade from marginal planting or a strategically placed boulder helps stabilize temperature through the hottest weeks.
Will clay soil cause problems for a pond in Concord?
Clay soil is common through Concord and it moves with seasonal moisture, which is why we build with flexible EPDM liner rather than a rigid fiberglass shell. The liner accommodates that movement instead of resisting it. We also pay close attention to how the excavation is backfilled and compacted so the edges stay stable over years rather than settling unevenly.
Do ponds attract mosquitoes in a hot inland climate?
A properly built pond does not. Mosquitoes need still water to complete their cycle, and a pond on continuous circulation with a skimmer and BioFalls filtration never gives them that. The moving surface is actively hostile to larvae. In practice a healthy pond reduces the mosquito pressure in a yard, because any standing water that was there before gets replaced by water that is always in motion.
Can a pond work in a standard Concord tract backyard?
Yes, and a good number of our Concord projects are exactly that. A rectangular flat yard is straightforward to work with, and the design usually focuses on creating a natural-looking edge and enough elevation change to give the water somewhere to fall from. We size the feature to the space so it reads as generous rather than crowded.
What is the best time of year to build a pond in Concord?
Fall and spring are the easiest windows, mainly because working through peak summer heat is harder on the crew and on new plantings. That said, we build year round and a summer installation is entirely workable. Starting in fall means the pond has settled and the planting has established before the following summer, which is when you will most want to be using it.
