Where utility bills are not available (such as in a leased property), we estimate based on internal estimation intensities by building type. These estimation intensities are calculated annually based on actual data. We use the same boundary in calculating water withdrawals as in our greenhouse gas emissions calculations. Water is withdrawn from municipal sources (except for a small amount of rainwater) and discharged to municipal sewer systems. Water consumption is equal to water used for irrigation. Data for groundwater and rainwater are sourced from meter readings for the systems in place. Potable water is defined as water treated to levels that meet state and federal standards for consumption. For BAC, this includes all water except grey water used for irrigation, untreated groundwater, and reclaimed water. Water values are recalculated back to the base year when a change to a prior inventory would result in a change in water values of 0.5% or greater. Therefore, prior year values shown in the current year of this report may not match the values published in prior reports. Baseline water stress is determined according to the WRI Aqueduct Water Risk Atlas tool.
