Does it make sense to proceed on a path that treats the entire wastewater stream to a level that may be required for discharge to the Gallatin? If a majority of the volume of wastewater is intended to be used for golf course or other irrigation purposes, why would the district go to the expense of treating to further reduce the nutrients that are allowed for irrigation?
Advanced treatment final design is several years out. At that time, a decision will be made as whether to treat all flows through Advanced Treatment or only those flows going to subsurface, or snowmaking, or direct discharge, or some combination of those. The issue with this is that “fit for use” distribution could require multiple distribution pipelines.
