Today, 35.8% of the world’s population still lacks access to any proper sanitation facilities.
That’s why in 2015, the world’s leaders agreed to strive for access to adequate and equitable sanitation and hygiene for all by 2030 as part of the United Nations Sustainable Development Goals. That means more than three billion extra people will need access to a toilet.
But if we solve this problem with the flush toilets we’re used to in the West, we will have a whole new water access and sanitation problem on our hands.
From toilets to treatment
The invention of the flush toilet, or water closet, in 1596 ended open defecation and transferred excreta outside of homes for the first time. This was certainly a good thing in the short term, but today the flush toilet probably stands as one of the most unsustainable innovations in human history.
Think about it. Why would we want to increase the liquid volume of a potentially harmful substance – human waste? Most of the waste water that flush toilets create – more than 80% worldwide – ends up going directly back into the environment. No treatment, no use, just a lot of open sewers.
With the invention of flush toilets, the volume of waste created when humans go to the bathroom increased almost 20-fold. To deal with this new level of waste, we invented waste-water treatment plants. The aim of these sewage treatment systems has traditionally been to provide clean effluent that can be put back into the ecosystem.
Scientific Name: Alternanthera philoxeroides A native of South America, alligatorweed was inadvertently introduced to Southeastern U.S. in the late 1800s. Its white flowers are clover-like and bloom a summer. Most commonly found floating in mats along the water’s edge, alligatorweed also grows immersed and even terrestrially. Its opposing leaves are lance shaped, 1-2 inches long, […]
Do you know where the water that flows into a storm drain goes? This water does not go to a treatment plant but flows directly into our streams, lakes, and rivers. Many people poor oil, paint, yard waste, and other pollutants into the storm drain because they think the water will be treated before […]
RiverLink and MountainTrue have developed informational kiosks for each river access point along the French Broad River Paddle Trail with a grant from the North Carolina Recreational Trails Program. Each kiosk focuses on historical and natural features of the river, as well as paddle trail information including maps and boater resources. These kiosks aid users and […]
