Stormwater Utility Enterprise Fund

In 2023, the Town of Wellesley adopted a Stormwater Utility Enterprise Fund similar to Wellesley’s existing water, sewer, and electric utilities, to more equitably distribute the necessary expenses that are required to meet increasing demands associated with the Town’s stormwater management program. Wellesley is facing federal requirements to reduce the amount of pollution from stormwater runoff discharging to waterways, including substantial phosphorous reduction requirements of runoff into the Charles River. Consequently, the Town must increase investment in stormwater infrastructure management to meet permit obligations.

The purpose of the federal requirements is to reduce the amount of pollution from stormwater runoff discharging into waterways.  Wellesley is in the Charles River Watershed and is required to substantially reduce phosphorous runoff into the Charles River. As a result, the Town must increase its investment in stormwater infrastructure management to meet these requirements.  

Previously these investments were funded through taxes. Starting in FY25, under the Stormwater Utility Enterprise Fund, a fee will be applied to all non-municipal properties including those owned by tax-exempt, non-profit and state agencies.  The stormwater fee is based on the amount of impervious surface on each property. Impervious surfaces are any hard material that prevent stormwater from infiltrating into the ground and include parking lots, driveways, and buildings. 

The Environmental Protection Agency (EPA) considers an enterprise fund to be a best practice to promote and maintain long-term financial sustainability for stormwater activities.  For Wellesley, we believe that a Stormwater Utility Enterprise Fund is a practical and more equitable way to fund and distribute the costs of this important program.

Stormwater Utilities Throughout New England

Communities throughout New England have developed Stormwater Utilities to fund stormwater management goals and/or MS4 Permit Requirements. The graphic below demonstrates Stormwater Utilities adopted in the Northeast as of 2023. The Massachusetts Department of Environmental Protection (MassDEP) maintains a database of stormwater utilities in Massachusetts here
