Apple grantee Gravity Water prepares the following technology of water stewards in Vietnam
With its progressive, climate-resilient rainwater harvesting and filtration know-how, 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 upon the assets it gives, 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 ample, many locals have come to comprehend that the water will not be 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 technology to the following {that a} water deity — or a rain god — is barely good to the individuals 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 situations, sustaining the standard of the water is out of the lakeside communities’ arms. With out correct filtration, groundwater retrieved from broken wells is contaminated with calcium and different metals, whereas the streams operating 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 sluggish to nothing greater than a trickle.
On the faculty Hương’s son attends, international clear water group Gravity Water has put in its progressive rainwater harvesting system to offer the lecturers and college students — lots 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 carry protected, clear water to 131 faculties in northern Vietnam. This collaboration is related with Apple’s water technique to handle water availability, water high quality, and water accessibility in its provide chain all over the world. Making use of confirmed applied sciences to advance water entry, sanitation, and hygiene (WASH) in areas reminiscent of Hòa Bình province displays the breadth of the efforts.
Utilizing a human-centered design method, Gravity Water companions with every faculty to find out their distinctive challenges and construct the appropriate resolution for them. This method 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 gives.
“Weekly, we have now 5 installations, and we get excited as a result of we get to go to each faculty, and each faculty is totally different,” says Phan Viet Dung, Gravity Water’s mission supervisor in Hòa Bình, who grew up within the province. “Transportation, the space among the many faculties, and the circumstances of the infrastructure are all so totally different. So at some faculties, they lack instruments, and in others, the water provide is unstable. We have now to be sure that it doesn’t matter if the water supply is secure or unstable — the college has clear water obtainable 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 generally lasts for one to 2 months between October and April, the province faces extreme drought. The summer season months carry 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 concern: Extreme flooding and landslides are growing in frequency in essentially the most susceptible communities, additional polluting obtainable water sources. However Gravity Water hopes to shift the notion of heavy rain as a local weather menace, to one in all its greatest 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 will not be new to Vietnam; it’s one of many world’s oldest applied sciences. I’ve gone to colleges which have bamboo items reduce in half amassing water off of roofs into totally different tanks. We have now an enormous alternative to scale our know-how and impression in these rural communities.”
By connecting a big weatherproof water tank to a collection of sensible meters to observe ranges of groundwater use and what’s collected from rainfall, Gravity Water is making certain faculties can have a dependable water supply year-round. The system is absolutely automated, counting on the water stage sensors to find out when to offer water — and from which supply — to the college’s kitchens, bogs, and dormitories the place the scholars bathe and wash their garments. The workforce can be coaching the college’s administration on learn how to monitor the college’s water consumption month to month. The lecturers then take that monitoring a step additional into their school rooms, modeling good water stewardship and hygiene practices within the college students’ day by day classes and nonacademic actions.
“We have now loads of periods to show children right here learn how 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 must be answerable 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 bogs, so we have now to learn to use water effectively. For instance, we solely get water once we are thirsty, and we have now to complete it. We must 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 answerable for the youngsters’s well being and wellness.
“The youngsters are comfortable on a regular basis, they usually have loads of vitality,” says Liên. “Yearly, I’ve applications to show youngsters learn how to care for themselves and learn how to keep good hygiene. However there are loads 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 lecturers have to make use of water fastidiously,” 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 be sure that we will reuse water.”
“We’re adults, so we’re conscious of the connection between our security, our well being, and the atmosphere,” says Phạm Thiên Nam, Hiền Lương’s principal. “We have now a saying in Vietnamese that we eat cooked meals and boiled water. We wish the youngsters to study the identical factor, in order that they not solely have the data but in addition can keep 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 methods. Rainwater harvesting in the course of the heavy monsoon season is one nature-based, cost-effective approach to bridge the hole.
“We remodel the drawback to a bonus, so we have now 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 tasks all over the world to additional scale its rainwater harvesting know-how as a climate-resilient resolution for faculties and essentially the most susceptible communities. In Nepal, its methods are offering over 60 communities within the Kathmandu Valley with entry to wash water. In Taipei, Taiwan, the group helps 48 faculties and town run its operations off rainwater. In Malaysia, Gravity Water’s know-how is offering one other 50 faculties entry to protected consuming water. And in Mexico, it’s partnering with Isla Urbana, an area rainwater harvesting firm that builds city, rural, and college rain methods. With every of those tasks, Gravity Water is amassing real-time information to measure impression and monitor the effectiveness of its system.
By 2030, Gravity Water plans to carry protected, clear water to 1 million constructions by way of 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 nations, the group is optimistic a few future that retains communities related to their atmosphere.
“Local weather resilience is strengthening individuals’s relationship and understanding of their pure assets,” says Wright. “For the following technology of scholars and the individuals inheriting this planet, understanding the significance of saving water is so crucial. We’re actually excited to carry this schooling program to youngsters to assist them truly see their water use, see the rainwater harvesting, and get enthusiastic about it. And possibly that’s going to vary conduct as a result of whereas they’re washing their arms, they could say, ‘Hey, if I flip this faucet off, possibly 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.”
