The Massachusetts Water Resource Authority serves a total of 61 communities in Massachusetts. Out of these 61 communities, 16 receive only water service, 15 receive only sewer service, and 30 receive both water and sewer services from the MWRA.

This image represents the communities served by the MWRA. More information can be seen by visiting the MWRA at their web page.

This makes for a total of about 2.5 million people being served by the MWRA. This also includes 870,000 households and 5,500 businesses. However, in some communities, MWRA is not used as the primary water or sewer service. Nine of the 61 communities use the MWRA as a partial water supplier, meaning that they receive part of their water from the MWRA and other water from another source. Two communities only use the MWRA as a back-up supply in case of emergencies. If their own water supplier was to fail, they would rely on the MWRA for their water services.

While the MWRA currently serves approximately 2.5 million people, they do have a carrying capacity of approximately 2,747,252 million people (based on current figures). This is the maximum amount of people that they can serve based on the maximum amount of water that they can use each day. As the population throughout Massachusetts rises, the population served by the MWRA gets closer to its carrying capacity. As this point is reached, the MWRA will have to consider what will need to be done in order to continue service to its communities. These considerations might involve having the communities cutback on their water usage. This will allow for more people to be served. Another consideration would be to think of the sources where the water comes from and how more sources could be used to provide water to these communities.

Many important factors will need to be considered as the population served by the MWRA rises. These factors might affect the service provided to the communities in both positive and negative ways.
