CDM Smith is a leader in tailoring effective, creative reuse programs that incorporate both non-potable and potable reuse into water supply portfolios, while improving water quality and minimizing demands on traditional water supplies.

Advanced water treatment expertise

Our experience includes micro- and ultra-filtration, nanofiltration, RO, UV advanced oxidation, GAC, evaporation ponds, membrane bioreactors and more.

Navigating complex regulatory challenges

CDM Smith utilizes our relationships with regulatory authorities to adapt to evolving and often complex reuse regulations.

An understanding of
industrial challenges

We work with industrial clients to meet water supply and reliability needs, improve water use and reuse efficiency and optimize treatment.

Potable reuse implementation

CDM Smith delivers visionary solutions in potable reuse, through pilots, design and full-scale project implementation, ensuring stakeholder trust.

How does pilot testing optimize water treatment?

Jill Tedder, environmental engineer and water reuse extraordinaire, sat down to share her piloting secrets: pushing the limits of existing technology, why piloting adds value, and what it's like to work on these projects firsthand.
