Learn About Water Issues - Join a Tour!

The Falmouth Pond Coalition organizes educational tours to increase understanding of issues affecting fresh and saltwater ponds, rivers, estuaries, and bays in Falmouth. Among the sites we visit are the Massachusetts Alternative Septic System Test Center in Mashpee. Please contact us at falmouthpondcoalition@gmail.com if you are interested in either of these tours or if you have other educational sites to recommend. 

Saving our Waters by Installing Eco-Toilets and Urine Diversion Devices

Keeping urine out of our ponds, rivers, estuaries, and bays will do more to protect our waters than anything else we can do, including banning the use of fertilizers, installing Innovative/Alternative (I/A) septic systems, limiting road runoff, etc. Eco-toilets that divert urine or incinerate waste are a great option. Check out these links for the Wostman Eco-Flush and the Cinderella Comfort. Please contact falmouthpondcoalition@gmail.com for more information.

Volunteers Build Detailed Database Of Pond Health Throughout Falmouth


Three women each raised their hands to their brows, blocking the sun as they looked out over Cedar Lake where they watched a contractor spread an herbicide in the water from a boat. It is a special kind of herbicide, both they and Falmouth Pond Coalition founder Kim Comart said, one specifically designed to kill one pesky and invasive plant: fanwort.


One of the women, Joyce L. Bock, whose home offered the perfect vantage point for viewing the contractors’ work, said it probably got into the waterbody when someone dumped their home aquarium out into the water. Now, it has taken over a substantial portion of the lake and when it blooms white flowers over the surface of the water, she said it looks like a meadow. The contractors were being paid with funds raised by neighbors of the pond for the first phase of a project years in the making, she said. The immediate plan is to rid half of the lake of fanwort. The other half will be funded in the second phase, although Ms. Bock did not know when that phase will be approved.

Water Quality Advocates Want To Make UD Project Less Restrictive


A urine-diversion study is on the horizon and the Falmouth Water Quality Management Committee has wrestled with the details of how it might work, specifically whether homeowners participating in a pilot project would have to swap out all their toilets for urine-diverting devices.


Members discussed the topic during their meeting on May 22, two days after the select board approved an agreement with the Massachusetts Alternative Septic System Test Center for a urine-diversion feasibility study.


The study, funded with $80,000 in American Rescue Plan Act (ARPA) funds, will address unanswered questions about a potential town-funded urine-diversion pilot project. The three-year project would gather data from up to 75 participating households to measure the effectiveness of the practice and give the Massachusetts Department of Environmental Protection information on whether urine diversion is a technology that could effectively replace expensive innovative/alternative septic systems.


Urine diversion is a wastewater management method in which urine is collected instead of being flushed down the toilet. Nitrogen and phosphorus are nutrients found in human pee, so diverting urine from the waste stream lowers the amount of those nutrients that can make their way into the town’s estuaries. That would help the town meet state requirements for Falmouth and other Cape Cod towns for reducing nitrogen in local watersheds in coming years.

Two Birds With One Tiny House - Editorial


The town is facing two major problems, and the solution to one often exacerbates the other: wastewater and affordable housing. Unless a development is on the town sewer, opposition to affordable housing (whatever other motives may be in play) can legitimately be grounded in the fact that more toilets will further degrade our coastal ponds.


But a possible route to increasing rental housing stock without environmental damage exists: tiny houses and accessory dwelling units with urine-diverting toilets.

Falmouth Moves Forward With Study To Answer Questions About Urine Diversion Pilot


The select board this week approved an agreement with the Massachusetts Alternative Septic System Test Center for a urine diversion feasibility study. 

The study aims to provide answers to questions Town Meeting voters had about a urine-diversion pilot project, when they decided not to approve it last month. The four-year pilot project would gather data from up to 75 participating households to measure the effectiveness of the practice.

Town’s Freshwater Ponds Get A Vote Of Support – Letter -- April 26, 2024


It was fitting that this past Monday, Earth Day, the select board approved six candidates for the newly established Freshwater Ponds Advisory Committee. Their votes represented a major milestone and expression of support for Falmouth’s 75+ freshwater ponds.


The committee will help raise awareness of the importance of protecting our freshwater ponds and will work with our town manager and select board to integrate pond protection strategies into Falmouth’s strategic plan. By doing so, the committee will help affirm the responsibility of the town government to actively engage in freshwater pond protection.

Falmouth Adopts Resolution Recognizing The Rights Of Nature


The select board this week made Falmouth the first community on the Cape and one of only a half-dozen municipalities in the nation to adopt a resolution recognizing that humanity is a part of nature, is responsible for nature’s care and should recognize nature as having the right to exist, persist, regenerate and be restored.


The resolution acknowledges Cape Cod’s unique landscapes—from its coastlines to its aquifer—and establishes the global climate change problem and an ever-increasing need to address the crisis.

Town Management Takes Reins On Urine-Diversion Project

Falmouth town staff are working to resolve questions hanging over a proposed urine-diversion pilot project after the finance committee last week said it would recommend indefinite postponement of the idea at April’s Town Meeting.The plan is to bring the article back with all questions answered by the November Town Meeting.

Town manager Michael Renshaw told the select board during its meeting on Monday, March 11, that staff began meeting with Article 22 petitioners—Hilda Maingay, Earle Barnhart and members of the Falmouth Pond Coalition—after the finance committee said it had many unanswered questions concerning the program. Committee members generally said they supported the premise of the article, but they needed their questions answered. Mr. Renshaw said he and the assistant town manager plan to take the lead on making sure that all the details of the project come together for November’s Town Meeting.

Falmouth Water Quality Committee Endorses Urine-Diversion Pilot

The water quality management committee officially recommended that the select board support a citizens petition article that would fund a urine-diversion pilot project. The committee and its partners have been planning this pilot for months, and Town Meeting members will vote on whether to appropriate $1.9 million for the project in April.

Putting Urine To Work For Us 

By Hilda Maingay and Earle Barnhart 

Most of the nitrogen and phosphorus in our wastewater that pollutes our ponds and estuaries comes from one concentrated source: urine. A full 80 percent of the nitrogen in the wastewater is from urine, but urine is only 1 percent of the volume of residential wastewater—120 gallons per person per year. If that urine is diverted from the waste stream and collected, it will not go into the environment and pollute downstream ponds and estuaries. But if Falmouth does a urine-diversion pilot project and diverts the urine of 100 people from 50 homes, the question arises, “What do you do with that urine?”

Falmouth Select Board Creates Committee To Champion Town's Fresh Water Ponds 

The Select Board voted this week to create a new freshwater ponds advisory committee, tasked with finding solutions to pollution that is stifling freshwater quality across Falmouth.


This committee will be the first of its kind in protecting the town’s freshwater ponds. Town Manager Michael Renshaw suggested the select board appoint five committee members when it interviews prospective candidates at a future meeting. The board will vote on committee members once residents have had the opportunity to see the advertisements and apply to volunteer.
