HPWA is a 501(c)(3) charitable organization.


HPWA was established in 2007 as a volunteer neighborhood association within the state-designated "Herring River Watershed Area of Critical Environmental Concern" (ACEC). We focus on the total environment and the health of all the water in our watershed – from the groundwater we pump and use in our homes, to the water in ponds and streams that we enjoy for recreation, to that used by animals and wildlife in our neighborhood.  

HPWA is a member of the Watershed Action Alliance of the Southeastern Massachusetts.

What We Do

  • Sample and analyze pond water, establishing a long-term record of its quality.
  • Sample storm water runoff.
  • Educate residents about the crucial role they play in using water responsibly and preventing its pollution.
  • Study water flow in and out of our ponds.
  • Promote boating safety.
  • Sponsor numerous membership meetings each year in which we report on our work and discuss topics of general interest, e.g. area history, local bird life, herring migration, storm water runoff mitigation. 
  • Publish a newsletter a few times a year.
  • Elect ​officers and an executive committee that sets policies. We also have working subcommittees. 


All of our activities are based on the work of VOLUNTEERS supported by dues, private contributions, grants, and collaborations with organizations, the towns of Plymouth and Bourne, and the state.




We are always welcoming new members. Contact us to join, volunteer, or donate.
