If you thought direct potable reuse (DPR) permitting looks like indirect potable reuse (IPR) permitting, you’re right — but it’s ✨a lot more.✨
Check out our new DPR Permitting Roadmap, which brings together all of the permitting requirements from California’s DPR regulation into a concise, easy-to-use sheet.
🔑Key features of the roadmap:
- Six key deliverables required for a DPR permit application
- Multiple supporting documents
- An “implicit” requirement for pilot or demo testing
- Expanded requirements compared to IPR
As the pioneering agencies move forward with DPR in California, we’re helping them navigate this complex new framework. Reach out to our Potable Reuse Regulatory Lead, Anya Kaufmann, to learn how we can support your project!

BIG NEWS! California approved its regulations for Direct Potable Reuse yesterday, only the second state in the US to do so. This is the final piece of the potable reuse regulatory suite in California that now has regulations for all forms of potable reuse (both indirect and direct potable reuse).
Congratulations to the State Water Resources Control Board, WateReuse California, and the water reuse industry as a whole for all the hard work to get us to this point. Trussell is proud to have been involved in this process through our research and engagement with DDW on behalf of water agencies and WateReuse California. We are excited to continue helping our clients pursue DPR under this new regulatory paradigm.
For those of you interested in learning more about what DPR looks like in California, please see our new cheat sheet of the core requirements for DPR. Reach out if you have any questions or want additional help planning, permitting, designing, testing, or operating a DPR project.
