Intracep has filed an extensive patent application for permeable reactive weir (PRW) technology. This innovative surface water treatment technology is a small concrete dam with multilevel fish passage built in. Like traditional surface water weirs, PRWs create step pools that settle particulates and oxygenate the water. Unlike traditional weirs, the PRW removes pollutants (including thermal) and provides fish passage.

After nearly a year of research and design, the PRW technology is now patent pending.
