Regarding target setting questions for blue water, grey water, and a facility's reduced absolute water use; Do meters for domestic vs. industrial water uses need to be separated? If so, is there a time deadline that facilities need to meet?

If the facility does not have separate meters for industrial and domestic use, in such scenarios estimation methods can be used for reporting. The calculation methodology should be clearly defined and supported by verifiable data. Tracking domestic and production water use separately can help facilities further identify specific areas for improvement and conservation efforts. It recommended that the facility should install separate meters for tracking industrial and domestic water use separately, but if they are not able to do so, it is recommended for them to answer no to the question on separating it as per domestic and production and set targets and baselines for the total water use.
