Apple grantee Gravity Water prepares the following era of water stewards in Vietnam
With its revolutionary, climate-resilient rainwater harvesting and filtration expertise, Gravity Water is offering over 38,000 college students in Hòa Bình province with a clear water supply
Snaking round Đà Bắc district in northern Vietnam’s rural Hòa Bình province, Hòa Bình Lake continues to be and tranquil. Households of farmers are sprinkled alongside its banks, coexisting with this expansive physique of water. Their livelihoods rely on the assets it supplies, together with shrimp and freshwater fish, and when the pure streams coming off the mountains above aren’t sufficient — particularly within the dry season — the lake’s water itself.
However in a spot so lovely with water seemingly so considerable, many locals have come to comprehend that the water isn’t secure. In some Dao households, an ethnic minority group that migrated to Vietnam as early because the twelfth century, a perception is handed down from one era to the following {that a} water deity — or a rain god — is simply good to the folks if they’re good to the water.
“If we soiled the water, our water god will hit us in a detrimental means,” says Trần Thị Lan Hương, an administrator on the native Vay Nua Major and Secondary Boarding Faculty for Ethnic Minorities, the place her son Màn Xuân Phûc attends second grade. “So we attempt to maintain the water sources clear.”
In lots of cases, sustaining the standard of the water is out of the lakeside communities’ palms. With out correct filtration, groundwater retrieved from broken wells is contaminated with calcium and different metals, whereas the streams working off the mountains are diverted or polluted in on a regular basis agricultural practices — like irrigating rice fields and elevating cattle — earlier than they proceed down the mountain. And within the dry seasons, the streams can gradual to nothing greater than a trickle.
On the faculty Hương’s son attends, world clear water group Gravity Water has put in its revolutionary rainwater harvesting system to supply the academics and college students — a lot of whom dwell within the faculty’s dormitories from Monday to Saturday — a climate-resilient clear water supply. In 2023, Apple awarded Gravity Water a grant to convey secure, clear water to 131 faculties in northern Vietnam. This collaboration is related with Apple’s water technique to deal with water availability, water high quality, and water accessibility in its provide chain world wide. Making use of confirmed applied sciences to advance water entry, sanitation, and hygiene (WASH) in areas equivalent to Hòa Bình province displays the breadth of the efforts.
Utilizing a human-centered design strategy, Gravity Water companions with every faculty to find out their distinctive challenges and construct the fitting resolution for them. This strategy permits the faculties to have full possession by counting on the familiarity of their present water storage system and the automation Gravity Water’s intervention supplies.
“Weekly, we’ve got 5 installations, and we get excited as a result of we get to go to each faculty, and each faculty is completely different,” says Phan Viet Dung, Gravity Water’s mission supervisor in Hòa Bình, who grew up within the province. “Transportation, the gap among the many faculties, and the circumstances of the infrastructure are all so completely different. So at some faculties, they lack instruments, and in others, the water provide is unstable. Now we have to make it possible for it doesn’t matter if the water supply is secure or unstable — the varsity has clear water out there on a regular basis.”
Hòa Bình, which is classed as having a subtropic monsoon local weather, experiences two distinct seasons. On the peak of the dry season, which usually lasts for one to 2 months between October and April, the province faces extreme drought. The summer season months convey heavy rains, some years totaling upward of 45 inches. As seen all through essentially the most densely populated elements of the world additionally located within the subtropics, rainfall is each a necessity for nature and life to thrive, but in addition one thing to worry: Extreme flooding and landslides are rising in frequency in essentially the most susceptible communities, additional polluting out there water sources. However Gravity Water hopes to shift the notion of heavy rain as a local weather risk, to one in all its greatest options.
“Our philosophy is that rainwater has the power to essentially shift the needle in water entry for the individuals who want it most,” says Danny Wright, Gravity Water’s government director, who based the group in 2016. “Rainwater harvesting isn’t new to Vietnam; it’s one of many world’s oldest applied sciences. I’ve gone to varsities which have bamboo items reduce in half gathering water off of roofs into completely different tanks. Now we have an enormous alternative to scale our expertise and affect in these rural communities.”
By connecting a big weatherproof water tank to a collection of good meters to watch ranges of groundwater use and what’s collected from rainfall, Gravity Water is making certain faculties may have a dependable water supply year-round. The system is totally automated, counting on the water stage sensors to find out when to supply water — and from which supply — to the varsity’s kitchens, loos, and dormitories the place the scholars bathe and wash their garments. The crew can also be coaching the varsity’s administration on the best way to monitor the varsity’s water consumption month to month. The academics then take that monitoring a step additional into their lecture rooms, modeling good water stewardship and hygiene practices within the college students’ every day classes and nonacademic actions.
“Now we have a variety of classes to show youngsters right here the best way to use the water correctly,” says Hà Thị Dự, Vay Nua’s vice principal. “As a result of they dwell right here, they will study that it takes effort and time to have clear water.”
“For us as college students, every of us needs to be chargeable for our water provide,” says Bàn Thiên Anh, a seventh-grade pupil at Vay Nua. “That is the dry season, and we don’t have sufficient water from the supply within the streams. At occasions, we don’t have sufficient water to scrub the loos, so we’ve got to learn to use water effectively. For instance, we solely get water after we are thirsty, and we’ve got to complete it. We must always not waste it on the mistaken functions.”
At Hiền Lương Major and Secondary Faculty located on the financial institution of Hòa Bình Lake, the place one other Gravity Water system has simply been put in, Hà Hồng Liên leads a morning train routine throughout one of many college students’ 15-minute breaks from classes. As the varsity’s nurse, Liên is chargeable for the youngsters’s well being and wellness.
“The youngsters are comfortable on a regular basis, they usually have a variety of vitality,” says Liên. “Yearly, I’ve packages to show youngsters the best way to maintain themselves and the best way to preserve good hygiene. However there are a variety of college students at break time, they usually play and they’re thirsty. Earlier than Gravity Water, I used to be very involved about my very own well being and the youngsters right here, relating to the standard of the water.”
“Even academics have to make use of water rigorously,” Liên continues. “If we use water to clean the greens, we’ll use that water to clean the dishes or do one thing else afterward. So we make it possible for we will reuse water.”
“We’re adults, so we’re conscious of the connection between our security, our well being, and the surroundings,” says Phạm Thiên Nam, Hiền Lương’s principal. “Now we have a saying in Vietnamese that we eat cooked meals and boiled water. We wish the children to study the identical factor, in order that they not solely have the information but in addition can preserve their very own security.”
Whether or not at college or at residence, entry to ingesting water will be pricey within the communities throughout Hòa Bình, 70 % of that are populated by ethnic minorities incomes lower than $4 USD per day who can’t afford bottled water or family filtration programs. Rainwater harvesting throughout the heavy monsoon season is one nature-based, cost-effective solution to bridge the hole.
“We remodel the drawback to a bonus, so we’ve got extra water to fill in Gravity Water’s tanks and the varsity’s tanks,” says Chu Thanh Hoa, Gravity Water’s nationwide director in Vietnam.
Past Hòa Bình, Gravity Water has tasks world wide to additional scale its rainwater harvesting expertise as a climate-resilient resolution for faculties and essentially the most susceptible communities. In Nepal, its programs are offering over 60 communities within the Kathmandu Valley with entry to scrub water. In Taipei, Taiwan, the group helps 48 faculties and town run its operations off rainwater. In Malaysia, Gravity Water’s expertise is offering one other 50 faculties entry to secure ingesting water. And in Mexico, it’s partnering with Isla Urbana, an area rainwater harvesting firm that builds city, rural, and college rain programs. With every of those tasks, Gravity Water is gathering real-time knowledge to measure affect and monitor the effectiveness of its system.
By 2030, Gravity Water plans to convey secure, clear water to 1 million buildings by quite a lot of tasks and partnerships at faculties, with public infrastructure, and even in households. As extreme climate occasions proceed, and extra populations are impacted in each developed and creating international locations, the group is optimistic a couple of future that retains communities related to their surroundings.
“Local weather resilience is strengthening folks’s relationship and understanding of their pure assets,” says Wright. “For the following era of scholars and the folks inheriting this planet, understanding the significance of saving water is so crucial. We’re actually excited to convey this training program to youngsters to assist them really see their water use, see the rainwater harvesting, and get enthusiastic about it. And perhaps that’s going to vary habits as a result of whereas they’re washing their palms, they may say, ‘Hey, if I flip this faucet off, perhaps that line tomorrow goes to be decrease.’ And that’s what we’re actually hoping to do: encourage crucial pondering on how we will create options to assist have a greater relationship with our surroundings.”
