GO₂ Water is an environmental solutions company with patented, commercially-proven processes for treating wastewater and for recovering bioenergy, nutrients, and water for reuse while operating within a carbon-neutral ecological footprint.  Our innovative and unique technology has a forty-year operational history and has been placed at municipal and industrial facilities to meet U.S. EPA discharge standards at less than half the investment and one-third the operational costs of conventional wastewater treatment technologies.

GO₂ Water offers design, design-build, and turnkey solutions employing a technology that has been scientifically proven and thoroughly documented during decateds of rigorous testing, study, and improvement at UC Berkeley and at dozens of field sites under the names "Advanced Integrated Wastewater Pond Systems" and "AIWPS^® Technology," now branded as GO₂ Ponds. 

The GO₂ Water Difference

Conventional wastewater treatment is extremely capital- and energy-intensive, with high construction, maintenance, and operation budgets, large labor requirements, high carbon emissions, and daily production of sludge. Sewage sludge is infectious and is typically disposed of in a landfill, where its further decomposition results in the emission of methane, a potent greenhouse gas.

In contrast, GO₂ Water’s technology is carbon-negative and recovers energy through an optimal method of in-pond methane fermentation and biogas collection, and through biofixation of carbon dioxide into microalgae used in the process.  Because all the organic solids in the wastewater are anaerobically digested and converted to biogas, there is no sludge accumulation and thus no sludge handling or disposal necessary, which is virtually unique in the wastewater treatment industry. 

Also unique is our engineered use of microalgae to photosynthetically oxygenate the water and remove nutrients.  Whereas most aquatic plants release their oxygen to the atmosphere, algae release oxygen directly into the water through solar-powered photosynthesis.

Known in the scientific literature as Advanced Integrated Wastewater Pond Systems® (AIWPS®) and being newly branded as GO₂ Ponds, our method is a biomimetic technology that uses a series of ponds engineered to mimic the same environments and the same biological and chemical processes that nature itself uses to treat water contaminated with organic wastes and nutrients.

We are proud to present GO₂ Ponds as the most sustainable wastewater treatment, energy and nutrient recovery, and water reclamation technology available.  The advantages and economy we offer over existing technologies will allow us to play a key role in improving and extending sanitation throughout the world at significant savings.

The Unsustainable Way: Conventional wastewater treatment is costly, energy-intensive, releases greenhouse gases, produces infectious sludge for disposal in landfills, and is effected in tanks that last only about 20 years:

GO₂ Water's solution for wastewater treatment is better by every measure!
