Credit Interpretation Request - Use of Reclaimed Water To minimize the amount of potable water use within the facility, Building 510 facility has been designed to utilize reclaimed water provided by West Basin MWD and the City of Torrance to serve all of the project's flushing waste water and irrigation needs. West Basin MWD have advised Honda that Reclaimed Water should be available to the site in time for the building being completed in May 2007. American Honda is working closely with West Basin MWD and the City of Torrance to expedite this process and ensure that the Reclaimed Water connection is made in line with this schedule. The facility is currently under construction and the plumbing scheme is approved and being installed to include the use of reclaimed water, and both West Basin MWD and the City of Torrance are fully involved in this process. Despite American Honda's obvious commitment to using Reclaimed Water, there are a number of City logistical issues that may delay the actual Reclaimed Water activation date beyond the proposed occupation of the building. These primarily relate to achieving the following City of Torrance approvals: 1.The civil engineering works required to make the final branch connection from the reclaimed water main to the site. This would involve civil work on what is a major street and the City is concerned about the traffic impact, which may drive the schedule for this work. 2.The City of Torrance Plumbing and Reclaimed Water Inspectors have the final say as to when the Reclaimed Water supply. To minimize the risk associated with these approvals, both of which are outside of American Honda's direct control, American Honda are ensuring that both West Basin MWD and the City of Torrance have been fully involved in both the design and installation of the reclaimed water system. To support this CIR, we have additional documents from American Honda, West Basin MWD and The City of Torrance, confirming their commitment to providing the reclaimed water supply to the building, which can be provided if necessary. Can you please confirm that it is acceptable to take credit for the use of Reclaimed Water within our LEED NC 2.1 submittal even though final activation may occur after the building's initial occupation.
Update October 20, 2016: See the updated “Water Use Reduction Additional Guidance” document for new guidance on applying seawater or municipal wastewater to v2009 Water Efficiency credits.
Original ruling October 2, 2006
To meet the intent of this credit provide a contract signed by both parties, indicating that this water will be provided within a one year period from the LEED submittal. Submittal documents must also indicate required infrastructure for the use of this water and state that the local jurisdiction has approved the use of the volume of water for this project.
