Apple grantee Gravity Water prepares the following era of water stewards in Vietnam
With its modern, 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 remains to be and tranquil. Households of farmers are sprinkled alongside its banks, coexisting with this expansive physique of water. Their livelihoods rely upon the sources it supplies, together with shrimp and freshwater fish, and when the pure streams coming off the mountains above will not be sufficient — particularly within the dry season — the lake’s water itself.
However in a spot so lovely with water seemingly so ample, many locals have come to comprehend that the water is just not protected. 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 barely good to the folks if they’re good to the water.
“If we soiled the water, our water god will hit us in a adverse method,” 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 preserve the water sources clear.”
In lots of cases, sustaining the standard of the water is out of the lakeside communities’ fingers. 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 college Hương’s son attends, international clear water group Gravity Water has put in its modern rainwater harvesting system to supply the academics and college students — lots of whom reside within the college’s dormitories from Monday to Saturday — a climate-resilient clear water supply. In 2023, Apple awarded Gravity Water a grant to deliver protected, clear water to 131 colleges 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 akin to Hòa Bình province displays the breadth of the efforts.
Utilizing a human-centered design strategy, Gravity Water companions with every college to find out their distinctive challenges and construct the proper resolution for them. This strategy permits the colleges to have full possession by counting on the familiarity of their current water storage system and the automation Gravity Water’s intervention supplies.
“Weekly, we’ve 5 installations, and we get excited as a result of we get to go to each college, and each college is totally different,” says Phan Viet Dung, Gravity Water’s venture supervisor in Hòa Bình, who grew up within the province. “Transportation, the gap among the many colleges, and the situations of the infrastructure are all so totally different. So at some colleges, they lack instruments, and in others, the water provide is unstable. Now we have to ensure that it doesn’t matter if the water supply is secure or unstable — the college has clear water accessible on a regular basis.”
Hòa Bình, which is assessed as having a subtropic monsoon local weather, experiences two distinct seasons. On the peak of the dry season, which generally lasts for one to 2 months between October and April, the province faces extreme drought. The summer time months deliver heavy rains, some years totaling upward of 45 inches. As seen all through probably the most densely populated components 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 growing in frequency in probably the most weak communities, additional polluting accessible water sources. However Gravity Water hopes to shift the notion of heavy rain as a local weather menace, to one among its finest options.
“Our philosophy is that rainwater has the flexibility 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 is just not new to Vietnam; it’s one of many world’s oldest applied sciences. I’ve gone to colleges which have bamboo items minimize in half gathering water off of roofs into totally 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 sensible meters to watch ranges of groundwater use and what’s collected from rainfall, Gravity Water is making certain colleges can have a dependable water supply year-round. The system is totally automated, counting on the water degree sensors to find out when to supply water — and from which supply — to the college’s kitchens, loos, and dormitories the place the scholars bathe and wash their garments. The group can also be coaching the college’s administration on find out how to monitor the college’s water consumption month to month. The academics then take that monitoring a step additional into their school rooms, modeling good water stewardship and hygiene practices within the college students’ every day classes and nonacademic actions.
“Now we have a whole lot of classes to show children right here find out how to use the water correctly,” says Hà Thị Dự, Vay Nua’s vice principal. “As a result of they reside right here, they’ll study that it takes effort and time to have clear water.”
“For us as college students, every of us needs to be liable for our water provide,” says Bàn Thiên Anh, a seventh-grade scholar 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 wash the loos, so we’ve to discover ways to use water effectively. For instance, we solely get water once we are thirsty, and we’ve to complete it. We should always not waste it on the flawed 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 college’s nurse, Liên is liable for the kids’s well being and wellness.
“The kids are joyful on a regular basis, they usually have a whole lot of vitality,” says Liên. “Yearly, I’ve packages to show youngsters find out how to deal with themselves and find out how to preserve good hygiene. However there are a whole lot 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 kids right here, concerning 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 are going to use that water to clean the dishes or do one thing else afterward. So we ensure that we will reuse water.”
“We’re adults, so we’re conscious of the connection between our security, our well being, and the setting,” says Phạm Thiên Nam, Hiền Lương’s principal. “Now we have a saying in Vietnamese that we eat cooked meals and boiled water. We would like 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 house, entry to consuming water might 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 not afford bottled water or family filtration programs. Rainwater harvesting throughout the heavy monsoon season is one nature-based, cost-effective option to bridge the hole.
“We remodel the drawback to a bonus, so we’ve extra water to fill in Gravity Water’s tanks and the college’s tanks,” says Chu Thanh Hoa, Gravity Water’s nationwide director in Vietnam.
Past Hòa Bình, Gravity Water has initiatives world wide to additional scale its rainwater harvesting expertise as a climate-resilient resolution for colleges and probably the most weak communities. In Nepal, its programs are offering over 60 communities within the Kathmandu Valley with entry to wash water. In Taipei, Taiwan, the group helps 48 colleges and the town run its operations off rainwater. In Malaysia, Gravity Water’s expertise is offering one other 50 colleges entry to protected consuming water. And in Mexico, it’s partnering with Isla Urbana, a neighborhood rainwater harvesting firm that builds city, rural, and faculty rain programs. With every of those initiatives, Gravity Water is gathering real-time information to measure affect and monitor the effectiveness of its system.
By 2030, Gravity Water plans to deliver protected, clear water to 1 million constructions by quite a lot of initiatives and partnerships at colleges, 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 setting.
“Local weather resilience is strengthening folks’s relationship and understanding of their pure sources,” 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 deliver this training program to youngsters to assist them truly see their water use, see the rainwater harvesting, and get enthusiastic about it. And perhaps that’s going to alter habits as a result of whereas they’re washing their fingers, 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 considering on how we will create options to assist have a greater relationship with our surroundings.”
