The SFPUC Direct Potable Reuse demonstration team was honored by a visit from an old friend, Dr. Eberhard Morgenroth from the Swiss Institute of Technology. Eberhard, with colleague Miriam Hacker, first listened and learned about SFPUC's industry leading decentralized water reuse efforts, then turned the focus to decentralized potable water reuse. While not lacking water supply in Switzerland, they are dedicating their time to innovative online monitoring systems for water quality confidence, something vital to potable water reuse efforts. Looking forward to continuing the collaboration!
