Hilde Maingay and Earle Barnhart of the Green Center in Hatchville have argued and are still arguing that the use of sewer systems and treatment plants to deal with wastewater is not only energy-intensive, which contributes to climate change, but also expensive. Eco-toilets, or composting toilets, are neither energy-intensive nor expensive, they argue. Further, eco-toilets capture a valuable resource in the way of fertilizer.
It’s a tough sell on the Cape, where sewers are the go-to technology and innovative septic systems the runner-up. Eco-toilets are simply too radical an idea.
