How a laundry room revolutionized a New Jersey high school

The nonprofit Black Belt Unincorporated Wastewater Projects is installing advanced, three-stage wastewater filtration systems at homes in Lowndes County, Alabama, where effective wastewater treatment options are urgently needed. The nonprofit installs and maintains the systems for $20 per month, using two major federal grants to cover the upfront costs.

As New Hampshire schools debate the presence of police officers stationed in schools, one model they and other states can consider is found at Minnesota Intermediate School District 287. That district lowered in-school arrests dramatically by replacing school resource officers (SROs) with student safety coaches, trained in de-escalation tactics and crisis intervention. While some staff cite safety fears now, school officials say healthier relationships form between staff and students when help, not law enforcement, is the response to problems.

To help those experiencing homelessness, Seattle Public Utilities workers travel around the city knocking on RV doors and asking occupants if they need their sewage tank pumped. Some RVs are broken down and occupants can’t get to a public dump site to dispose of their waste, so wastewater spills have increased over the years. However, since the pilot program was introduced in 2020, the spills from RVs have been cut in half.

After realizing the difficulty that people in South Africa were facing when carrying water back to their communities, two South African engineers devised a machine "that brings all the water back in one trip by rolling it." Users report that while it does not perform well on steep terrain, it can carry much larger amounts of water "effortlessly and in a single trip." So far, 60,000 of these large plastic drums have been sold, but the cost of the machine is often a barrier for those who live below the poverty line.

Clarke County School District in Georgia has 21 public schools that all offer free meals to students, regardless of their financial needs. This is facilitated through a federally-funded program, so even though poverty rates are high in the area, local residents are not footing the bill. While there are still some challenges implementing the program, in general it is received well and allows students to focus on their work and well-being instead of being distracted by hunger.

The Bill Gates Foundation is currently funding a number of organizations that seek to solve the rate of open defecation by creating low-cost toilets that utilize the feces within them. One organization, called Sanergy, operates in 11 neighborhoods across Nairobi and uses a systems-based approach that takes into account financing and maintenance of the toilet as well as selling the waste as fertilizer. Another, called Tiger Toilets in India, uses a septic tank toilet that places worms within the drainage layer who then consume the feces and produce fertilizer to be used or sold.

With little access to clean water, the community in the Nebbi District in Uganda were facing health issues. A new government initiative, however, has changed this reality by implementing a water scheme that utilizes technology to trap water and transport it closer to the community.

In Senegal, emptying your septic taste is expensive business; the two options, hiring someone to shovel it onto the street or paying a high price to the "cartel of 'toilet suckers,'" are not sustainable for residents or public health. To force members of the raw sewage cartel to compete with each other and lower prices, a new call center "auctions" the service by text to individual sellers instead of forcing people to contend with a banded group, and "prices for toilet suckers have come down an average of 7 percent" since the program began.

Across the world, 1.8 billion people have to make a daily decision between either drinking unsafe water or paying exorbitant prices for bottled water. I-Drop Water, a company that has devised purification systems that can be installed at affordable rates in local grocery stores, is working to solve this problem by bringing accessible purified water to people throughout Africa.

Abel Cruz "catches" clouds on his fog net farm to help provide free water for his community in a slum on the outskirts of Lima, where access to water is very limited and costly. While this solution may never compete with large scale and traditional technologies, many argue there is enormous potential for this simple concept in certain, rural areas of the world.
