This spreadsheet is compiled on a quarterly basis from bills issued to MHC by the town after they read the College's various water meters. The meters are associated with different buildings and measure water consumption. Some buildings have individual meters,w hile some are grouped together (listed at the bottom of the spreadsheet.) The town then sends this spreadsheet to Facilities Management, which forwards the data to the Office of Sustainability for review and archival. The data is uploaded to IDA at the end of each fiscal year.
