I am working on a project that is installing reclaimed/recycled water lines to the project, with the goal to offset 60% of irrigation water with recycled water. However, the local water service currently does not have the capacity to provide reclaimed water to the site. This service may become available in the next few years, but a definitive time frame has not yet been given.

Can we still claim the 60% potable water use offset for the purposes of the irrigation credit? Is there a specific time frame that project needs to actually be provided with recycled water (i.e. within 2 years of operation?)
