Quality Pond Construction & Care Services in Brentwood
A custom pond changes the way you use your backyard. The sound of moving water, the movement of koi near the surface, the way the whole space settles into something quieter and more alive. That shift is what pond construction in Brentwood delivers when it is done right.
California Aqua Pros has been designing and building custom water features across the East Bay since 1993. Greg and Marlo Purkey started the company with the belief that a backyard pond should feel like it belongs in the yard, not installed over it. Every project begins with a conversation about how you use your outdoor space and what you want it to feel like. From there, we design a system that holds up over years of use, not just the first season.
Most of our Brentwood projects fall into one of a few categories. Koi ponds are the most requested. A proper koi pond requires more than a liner and some rocks. The filtration has to support the fish load, the depth needs to protect fish through summer heat, and the edges should look like they grew there. We are Diamond Certified and hold a Master Aquascape Contractor designation, which means we build to a standard that actually reflects how a pond ecosystem functions.
For homeowners who want the presence of water without the full commitment of a pond, pondless waterfall construction is often the right answer. The reservoir sits underground, the waterfall and stream run on a recirculating pump, and there is no standing water to manage or worry about. Families with young children often prefer this configuration. We also design and build fountainscape installations for smaller spaces or entry gardens where a naturalistic pond would feel out of scale.
Water gardens take a different approach, centering on aquatic plants, natural filtration, and the quiet visual of a pond that looks more like a pond in the wild than a constructed feature. These work especially well in Brentwood yards with morning sun and afternoon shade, where lilies and marginal plants thrive and the water stays naturally clearer.
Once construction is finished, keeping the system healthy is the ongoing work. Our pond maintenance team handles routine service on a scheduled basis, covering filter cleaning, water chemistry, aeration checks, and seasonal adjustments. You enjoy the pond. We keep it running.

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 Brentwood
Brentwood sits at the eastern edge of Contra Costa County, where the subdivisions along Sand Creek Road and Balfour Road give way to open agricultural land and the channels of the Delta. It is a community that has grown quickly over the past two decades while holding onto the open character that drew families here in the first place. Large lots, generous setbacks, and a lifestyle that spends real time outdoors define the neighborhoods we work in along Marsh Creek Trail and throughout the 94513 ZIP code.
California Aqua Pros has served Brentwood since the early years of our operation. We have built on newer properties in developments along Lone Tree Way and on older parcels where the yard has been a project for years. The East Bay warmth here, the long outdoor season, and the access to good well water in older areas all shape how we approach a Brentwood build.
We also serve the surrounding communities in this corridor, including our neighbors to the west in Danville. If you are in Brentwood and ready to put water in your yard, we know this area and we are ready to start the conversation.
Frequently Asked Questions - Brentwood Remodeling
What size yard do I need for a koi pond in Brentwood?
Most koi ponds start at around 8 by 11 feet with a minimum depth of 24 to 30 inches. Brentwood lots tend to give us room to work with, which means we can often go larger and incorporate a waterfall or stream feature. Smaller yards are better suited to a compact koi pond or a pondless water feature. We give you honest sizing guidance during the site visit based on what your yard actually supports.
How long does pond construction take?
A standard residential pond in Brentwood takes one to two weeks from excavation through final fill and planting. Larger builds with multiple waterfall tiers, extensive rock work, or custom filtration systems may run two to three weeks. We provide a clear timeline before we start and communicate any changes as the project moves forward.
Can koi live outdoors year-round in Brentwood?
Yes. Brentwood’s climate is well-suited for outdoor koi year-round. Winters are mild enough that koi slow their metabolism and stop eating actively but do not need to be moved indoors. Summer heat is the bigger variable. A properly aerated and filtered pond at adequate depth keeps dissolved oxygen high enough to protect fish through the hottest weeks.
Do HOAs in Brentwood have restrictions on water features?
Restrictions vary by neighborhood association. Communities along Balfour Road and newer developments off Lone Tree Way often have active HOAs with aesthetic guidelines. We recommend reviewing your CC&Rs before we begin the design process, and we can walk you through what to look for so there are no surprises during or after construction.
What does pond maintenance involve after the build?
A well-built pond with proper filtration needs consistent but manageable attention. Skimmer baskets need clearing every week or two, filter media gets rinsed monthly, and water chemistry should be checked periodically. Our pond maintenance team handles all of this on a scheduled service plan so you can enjoy the pond without managing the system yourself.
