Falmouth’s Eco-Toilet Incentive Program will establish how much nitrogen eco-toilets can remove from the human waste stream, in order to determine how useful these fixtures will be in reaching the town’s TMDLs.

Homeowners who participate in the voluntary program will receive a $5,000 rebate for the permitting, purchase and installation of eco-toilets to replace all the existing toilets in their home; in addition, they will receive a free septic tank pump-out (a $300 value). In return, the eco-toilet owner must allow regular testing of their septic system by the Barnstable County Department of Health and Environment for up to one year.

Working closely with regulatory agencies, a long-term goal of the program is to determine a nitrogen-removal credit for homeowners or businesses with eco-toilets. A total of 62 installations will be tested in order to quantify a nitrogen removal credit for regulatory purposes.

Costs & benefits

Further, these installations will document the technical details of various models of eco-toilets, both in terms of installation as well as operation and maintenance. This research project will also verify the installation costs and user experience of eco-toilets.

The cost, and practicality of retrofitting existing structures with eco-toilets is critical to an evaluation of whether these toilets are a viable alternative to more traditional wastewater management techniques. This demonstration program is endorsed by the Cape Cod Commission, and the results of this research will be used to quantify the effectiveness of these systems in their “Regional Wastewater Planning Matrix” planning tool.

Numerous installations of eco-toilets in Europe, Scandinavia and Australia have been documented. But Falmouth’s Demonstration Program is unique in that it will include specific measurements and analysis of nitrogen removal. As a result, at the end of the testing period, the town expects to have the experience to handle a range of difficulties encountered in installing and using eco-toilets.
