Every day, 120 students and nine staff members at Mwanziu Primary School face a water crisis. They have two water options, but neither provides sufficient or safe water to meet their daily needs.

"The school suffers from inadequate water availability due to the region's hot and dry climate, which forces students to carry water from home when the rainwater tank runs out of water. The school can only sprinkle the dusty and bare classrooms once in a while because the water is not enough. The water brought from home has also caused water-related infections like stomach upset and hygienic infections such as ringworms. Some pupils also fail to come to school when there is no water to carry from home. The latrines in the school are barely cleaned and have a bad odor, which has created an unconducive learning environment," shared Field Officer Alex Koech as he described the difficulties at Mwanziu.

Students collect water from various unprotected sources near their homes and haul it to school over dangerous rocky and hilly terrain, leaving them exhausted when they arrive. This time-consuming activity usually takes over an hour, which means students miss valuable learning time in class.

"The pupils bring water from home when the water in the rainwater tank is depleted. They mostly draw water from scoop holes or earth dams that are unprotected. The water is not clear with an unpleasant taste and smell," continued Alex.

Students carry their water jugs back and forth to school.

Collecting the water is a burden, but consuming the water they've collected leads to a whole new set of problems. The water is often contaminated, causing students and staff members to suffer from water-related illnesses that steal their time, health, and focus.

"The pupils often complain of stomach upsets and have to be sent home for treatment, and this is exactly what happened last week when one of the pupils had stomach pains," said Alex.

"Last week, one of our pupils complained of stomach pains, and we had to send her home to seek treatment. This happens often, and it is very sad because the pupils have to miss classes for the rest of the week. The pupil has to miss out on classwork, and in the case of a teacher, they will not come to teach until they get better," said 55-year-old teacher Alice Kailu.

"The rainwater tank cannot hold enough water for all of us during the several months of drought. The hot and dry climate also reduces the water supply in the scoop holes found in the local seasonal river. The students have to carry water from home every day when coming to school. Sometimes, we are unable to cook food for them when there is no water. The learners are also forced to use latrines that have an unpleasant odor," Alice continued.

But Alice hopes the school can benefit from a water solution and turn things around. With water access, she is confident that student's academic performances will improve and their learning environment will be much improved.

She concluded, "Living things require water to thrive, and the success of this school depends on water availability."

Steps Toward a Solution

Our technical experts worked with the local community to identify the most effective solution to their water crisis. Together, they decided to construct a rainwater harvesting system.

Rainwater Harvesting System
A rainwater collection system consists of gutters that channel rainwater effectively into large holding tanks. Attached to buildings with clean, suitable roofing, these systems are sized according to the population and rainfall patterns. Water can be stored for months, allowing for easy treatment and access.

Handwashing Stations
Alongside each water source, we install two gravity-fed handwashing stations, enabling everyone at the school to wash their hands. Handwashing is crucial for preventing water-related illnesses within the school and community. Student “health clubs” maintain the stations, fill them with water, and supply them with soap, which we often teach them how to make.

School Education & Ownership
Hygiene and sanitation training are integral to our water projects. Training is tailored to each school's specific needs and includes key topics such as proper water handling, improved hygiene practices, disease transmission prevention, and care of the new water point.

To ensure a lasting impact, we support forming a student health club composed of elected student representatives and a teacher. These clubs promote hygiene practices schoolwide and keep handwashing stations well-stocked. This student-led model encourages a sense of ownership and responsibility.

Safe water and improved hygiene habits foster a healthier future for the entire school.

Project Updates


April, 2026: Mwanziu Primary School Rain Tank Complete!

Your contribution has given access to clean water for the Mwanziu Primary School in Kenya, thanks to the completion of their 104,000-liter rain tank! Additionally, we installed handwashing stations and trained students and staff on sanitation and hygiene practices. Together, these components will unlock the opportunity for these students to thrive!

"Having reliable water in our school will really improve many things for me. Before the tank was built, we used to carry water from home every day, and sometimes I would feel very tired before lessons even started. The water we brought was often from scoop holes or earth dams, which were not clean and could make us sick. Now that we have enough safe water in school, we can drink clean water, wash our hands, and stay healthy. It makes me happy knowing that I will no longer have to carry water to school, and I can use that time and energy to focus on my studies," celebrated 14-year-old Joel.

Teachers were just as excited as the students about the new rain tank on campus!

"Having reliable water at school will greatly improve our pupils’ well-being and give them more time and energy to focus on their education. They will no longer have to carry heavy jerrycans from home or miss classes due to water-related illnesses. With a clean and healthy environment, learners will attend school regularly and concentrate better in class. When children are not distracted by basic needs like water, they can dream bigger, work harder, and have a better chance of achieving their goals," shared 58-year-old teacher Leonard Musili.

Rain Tank Construction

First, we held a meeting with all parents and the school’s headteacher to plan the project. The parents agreed to collect construction materials, such as sand, rocks, and water. We complemented their materials by delivering the expertise, tools, lumber, metal, cement, and a gutter system.

This tank holds a whopping 104,000 liters, as rainfall is rare in Southeastern Kenya. The more water the tank can store during the seasonal rains, the more water will be available for the students throughout the dry months!

Constructing this large rain tank is much like building a concrete house. First, we leveled the ground for foundation excavation. Next, we laid alternating layers of rocks and mortar up to seven feet high for the tank's outer walls. With such sturdy construction (the walls are three feet thick!), the tank will stand for a long time.

We built a reinforced concrete column in the center of the tank to support the roof and prevent it from collapsing. We plastered the walls inside and out with waterproof cement and installed guttering into the tank. Finally, we installed the roof of the tank, made of iron sheets and timber with vents to allow rainwater into the tank from the gutters.

Field Officer Alex Koech shared his view: "The progress made through the construction of the 104,000-liter rainwater-harvesting masonry tank and the hygiene training clearly shows that the school and its community are moving in a positive and sustainable direction. The water project has addressed one of their biggest challenges—water scarcity—which had previously affected health, hygiene, and learning. Now, with access to reliable and safe water, pupils no longer have to carry water from home or miss school due to water-related illnesses. This will greatly improve attendance, cleanliness, and the overall learning environment."

"The dedication and unity shown by the parents during construction—gathering materials, fetching water, and offering labor—demonstrate a community that values education and is willing to work hard for its children’s well-being. The school’s leadership is also visionary, with plans to start a vegetable garden, plant trees, and improve classroom floors using water from the tank. These initiatives show that the school is thinking beyond immediate needs and is focused on long-term development and sustainability," he continued.

Handwashing Stations

We delivered three new handwashing stations in time for training. Each new station has three taps, allowing nine students to wash their hands simultaneously.

School Education

We trained on health, hygiene, and sanitation topics. These included student health club activities, disease prevention, personal hygiene, and handwashing. We also covered topics such as water hygiene, latrine hygiene, and soap-making.

Thirteen-year-old Esther shared her favorite part of the training. "The most interesting topic for me was personal hygiene. I found it very important because it taught me how small daily habits—like washing hands at the right times, keeping our bodies and clothes clean, and trimming our nails—can help prevent many diseases. Before the training, I didn’t know that germs spread so easily through dirty hands and unclean environments. I learned that by practicing good personal hygiene, I can protect myself and others from sicknesses that often cause students to miss school. This topic made me realize that being clean is not just about looking neat, but also about staying healthy and strong."

"This training has completely changed how I think about hygiene. I now understand that hygiene starts with me and that every person has a role to play in keeping our school and homes clean!" declared Esther.

Thank you for making all of this possible!

Project Type

For a rainwater collection system, we build gutters around a building with good, clean roofing to channel rain where we want it. From there, the water falls through a filtered inlet pipe into a high-capacity storage tank, the size of which is based on population and average rainfall patterns. In the tank, water can be stored for months, where it is easily treated and accessed. Learn more here!
