In 2012, demand on the MWRA water system was 194.71 million gallons per day, average (mgd/avg).

For comparison:

2011: 196.6 mgd/avg
2010: 204.3 mgd/avg
2009: 194.3 mgd/avg
2008: 205.6 mgd/avg
2007: 219.9 mgd/avg
2006: 211.6 mgd/avg
2005: 259.2 mgd/avg

Based on a detailed analysis of major factors affecting water demand, MWRA projects that system demand will remain well below 300 million gallons per day.

An archive of water system demand data since 2005 is below.
