The East Cherry Creek Valley Water and Sanitation District (District) is constructing a 10 MGD brackish water reverse osmosis project to provide a new renewable water source to a portion of the southeast metropolitan Denver that is currently served exclusively from deep non-renewable groundwater. The District evaluated several concentrate disposal alternatives including discharge to the local POTW, direct surface water discharge, evaporation basins, deep well injection and zero liquid discharge. Objections from local agencies, regulatory issues and costs ultimately resulted in the District selecting a combination of brine minimization and deep well injection as the concentrate disposal approach for the project.
