ATTENTION BOSTON WATER AND SEWER COMMISSION CUSTOMERS You may have noticed some changes in your most recent bill from Boston Water and Sewer Commission. As of April 1, 2024 BWSC customers will now see three separate line-item charges on their bill, for water, sewer, and stormwater. Now, paying for stormwater separately will lower the sewer rate while showing the charges attributed to stormwater activities for the property. This is a more equitable way to fund improvements for the stormwater system because everyone pays for the service they use. Here are key highlights of the bill: Stormwater charge will be $8.98 per month for each Equivalent Residential Unit (ERU) attributed to the property. All property owners with more than 400 square feet of impervious area will be billed. 60% of residential households will see a reduction in their overall bill. The 30% discount extended to seniors and disabled residents will automatically apply to the new stormwater fee. Credits and grants are available for customers who implement green infrastructure measures on their property.
