CREW for wastewater operators

Optimize your operations and become part of the climate solution
We know that the first priority of wastewater treatment is meeting requirements for public safety and the environment. We’re here to help you do that — and more.
With CREW, wastewater facilities can surpass compliance and actively demonstrate a commitment to environmental stewardship. Our process streamlines treatment, reduces your carbon footprint, and improves cost efficiency — aligning greater sustainability with a better bottom line.
The result is a solution that benefits your facility, serves your community, and contributes to a better planet.
The CREW solution
Effortless integration
CREW can remove the cost barrier for alkalinity dosing by covering all CapEx and OpEx for first-time dosing or expansion of existing systems.
We can also handle the sourcing, verification, and dosing of soluble calcium carbonate from local providers according to your facility’s specific needs and capacity.
Cost-savings with CREW over traditional chemical treatment.
85%Realize process benefits
By replacing expensive, hazardous, and carbon-intensive chemicals like caustic soda or quicklime, CREW delivers safer, more consistent treatment at a lower cost and lower carbon footprint than standard methods.
Facilities currently using alkaline chemicals achieve significant cost-savings, while those using other methods increase treatment capacity and decrease environmental impact.

End-to-end measurement
Our platform and sensor arrays quantify both the process benefits gained and CO2 removed in real time, generating carbon credits — the next phase of resource recovery in the era of climate change.
With CREW, wastewater facilities can optimize operations and tap into a new source of revenue as they take a step toward decarbonization.
CREW wastewater partners can benefit from:
-
Cost savings
We provide significant savings relative to conventional methods for neutralization, buffering capacity, and alkalinity.
-
Enhanced safety
Our process eliminates risk exposure for operators by replacing conventional, hazardous chemicals for pH control.
-
Efficient compliance
CREW technology provides stable, more consistent biological and nutrient treatment to help facilities meet permit regulations.
-
Climate action
We reduce facilities’ carbon footprint by replacing carbon-intensive chemicals with locally-sourced minerals.

Wastewater operator partners
Our partner facilities worldwide are currently realizing process benefits, gaining cost-efficiency and actively removing carbon from the environment.


CREW technology is sound — their pilots to date have achieved their goals of reducing costs and improving pH and alkalinity management. The technology is safer than existing solutions, removing harmful chemicals like caustic from operations. And the technology is innovative — it’s truly a first-of-a-kind solution that transforms wastewater treatment plants into climate hubs. It’s a paradigm shift for the industry.
