Innovative Water Reuse Technology
Water reuse is the future. With climate change, population growth, and other issues facing us today, we must look toward recycled water to meet our needs. Carollo Engineers has long been a leader in engineering water reuse systems.
Our Water Reuse Projects include
- Tertiary treatment system design for reuse
- Advanced treatment design for potable reuse
- Potable reuse pilot and demonstration facility design, operation, and public outreach
- Regulatory, permitting, and funding support
- Reuse planning and feasibility studies

Helping communities expand their water supply
Water reuse relies on safe and effective technologies to treat and recycle available water without irresponsibly mining for limited resources. To consistently remain ahead of the curve, our in-house water research group monitors new reuse and treatment technologies and engages leading scientists, engineers, and regulators who keep us abreast of any changes that might affect our solutions in the near- or long-term. As a result, our reuse projects produce more than 40 billion gallons of reclaimed water each year. This water is used to irrigate crops, enhance parks, cool power plants, replenish and recharge our groundwater reservoirs, and much more.


The ABCs of Water Reuse
Carollo’s ABCs of Water Reuse is an illustrated guide that makes complex water reuse concepts simple, clear, and accessible to everyone. Co-developed by water industry experts and communication professionals, it provides technically accurate explanations in everyday language supported by vibrant graphics and relatable metaphors. Utilities, agencies, and educators can use the resource to start conversations at community meetings, support elected officials with confident messaging, and engage audiences through tours, school programs, and public events. By bridging the gap between technical detail and public understanding, the ABCs of Water Reuse empowers communities to recognize the value of recycled water and build support for sustainable solutions that make the most of every drop.
