Columbia Water Gardens is led by Carl Petite — a former Master Certified Aquascape Contractor (held for nearly a decade), Aquascape Business of the Year (2014), #2 contractor worldwide (2015), three-time global Top 20, active Atlantic-OASE Pro Contractor, and published author in POND Trade Magazine. Now free from Aquascape's exclusivity terms, we engineer living water features using the best products from any manufacturer — today specializing in Atlantic-OASE systems.
Past and present certifications earned through years of advanced training, global ranking, and a portfolio of living water features across Southern California.
A former designation: Carl held Aquascape's elite Master Certified Contractor designation for nearly a decade — the highest tier of certification awarded by the world's largest water feature manufacturer, requiring advanced ecosystem hydraulics training, biological filtration mastery, and a multi-year portfolio of installed living water features. He is no longer a certified Aquascape contractor and is not bound by their exclusivity terms, leaving Columbia Water Gardens free to build with the best products from any manufacturer — including the Atlantic-OASE systems we specialize in today.
Awarded Aquascape's Business of the Year in 2014 — the company's top global corporate honor — selected from thousands of certified contractors worldwide for excellence in craftsmanship, business operations, and customer satisfaction.
Ranked among the Top 20 Aquascape contractors in the world three separate times, peaking at #2 globally in 2015 — a recognition of installation volume, quality, and industry leadership measured against every certified builder on the planet.
Currently an active Atlantic-OASE Pro Contractor — the manufacturer's professional installer tier authorized to build and service systems backed by the exclusive 3-Foot Tape Measure Clear Water Guarantee, including FiltoClear, BioTec ScreenMatic², and ProfiClear filtration with AquaMax pumps and Bitron UV clarifiers.

Read real feedback on our Google Business Profile from homeowners across our service territory.
"Columbia Water Gardens transformed our vineyard estate into a living work of art. The koi pond they built looks like it has been here for a century — every boulder placed with intention, the water crystal clear without a single chemical. Our prized koi have never been healthier. Truly museum-grade craftsmanship."
"We replaced our sterile chlorine pool with a Natural Swimming Pond and it is the best decision we've made for our De Luz property. The water is silk-soft, the regeneration wetland blooms with native plants, and our kids swim in chemical-free living water every day. The team's biological engineering is unmatched."
"The pondless waterfall Columbia built on our La Cresta hillside sounds like a genuine Sierra mountain brook. They engineered the hydraulics so there is zero standing water — safe for our grandchildren and pets — and virtually no maintenance. The dry-stacked granite looks like a natural geological outcropping. Breathtaking."
"Our mid-century modern courtyard now features a hand-carved basalt column fountainscape that anchors the entire property. Even in 115-degree Palm Springs heat, the auto-fill and oversized reservoir keep it running flawlessly. Columbia understood desert hydraulics better than anyone we interviewed."
"Their weekly maintenance service is true resort-level care. The team shows up like clockwork, tests the biological balance, manages our koi feeding rate, and keeps the water magazine-cover clear. We never lift a finger and our pond has never looked better. Worth every penny for hands-off luxury."
"Bi-weekly service has been exactly the right cadence for our desert waterfall feature. Reliable, discreet, and meticulous — they clear the skimmer vaults, check the auto-fill, and leave everything pristine. Columbia treats our feature like their own. Genuinely the best service company we've worked with in the valley."
"Our koi pond had been neglected for years — green water, sludge, failing pumps. The Columbia cleanout crew safely housed our fish, pressure-washed every boulder, replaced the biological filtration, and restarted the ecosystem. It looks better than the day it was built. They brought it back from the dead."
"From the 3D hydraulic design review to the final stone placement, Columbia Water Gardens executed our Natural Swimming Pond with the precision of fine architecture. It is the centerpiece of our entire estate. Living waterfront is exactly the right phrase — we feel like we're on permanent vacation."
"The cascading stream Columbia built masks the road noise on our property entirely. The sound changed how we experience our patio — it's now our favorite room in the house, outdoors. Their mastery of acoustic engineering and water flow is genuinely artistic."
"I trust Columbia completely with our prized Nishikigoi collection. Their weekly visits include fish health evaluations, water testing, and biological adjustments that keep the ecosystem perfectly balanced. Our koi are thriving and growing beautifully. Professional, knowledgeable, and deeply passionate about their craft."
"The stacked slate urn fountainscape Columbia designed for our entry courtyard is an architectural sculpture, not a fountain. The gentle water melody greets every guest. They sourced stone with extraordinary grain and color variation. It elevates the entire front of our home."
"After a bad experience with another company's cleanout, Columbia reset everything to master standards. Transparent flat-rate pricing, no surprises, and meticulous biological restart. Six months later the water is still crystal clear with zero intervention on my part. They earned a customer for life."
