On many hillsides around Lima, water doesn't come from a tap. It arrives by truck, gets stored at the bottom of the slope and then has to be carried up the steps, bucket by bucket, several times a week. For families without a connection to the city network, every liter takes time, money and physical effort. That is the problem clean water and sanitation projects are built to solve.
These projects bring water closer to homes, create safe bathrooms and reduce the daily burden that missing infrastructure places on families.
In this article, you will learn why water and sanitation are so closely tied to health and opportunity in hillside communities, how two real community-led projects in Peru and Ecuador worked, and what engineering and architecture students can learn from this kind of infrastructure.
Many families in Lima's human settlements live outside the reach of the public water system. In communities like these, residents often depend on private water trucks. As we covered in our article on the eco-bathroom solution in Lima, families in water-scarce areas may pay up to 12 times more for water than residents of well-served neighborhoods, and its quality is not guaranteed.
Even when water arrives, it still needs to reach homes built high on steep slopes. That means hauling heavy containers uphill on unstable paths, a task that is especially hard for children, older adults and anyone with limited mobility.
Without safe bathrooms or a sewage connection, keeping homes and schools hygienic is much harder. Poor sanitation is linked to the spread of disease, and children are especially affected when their schools lack proper facilities. You can read more about the hygiene facilities in schools that help students stay healthy and in class.
Water and sanitation are also connected to land rights. In many settlements, families need legal recognition of their land before they can request public utilities like water and electricity. Permanent community infrastructure, like the staircase built in 2 de Diciembre, can support those efforts.
Safe Homes Movement is powered by MEDLIFE, which has worked alongside communities in Peru and Ecuador on water and sanitation for years. Two projects show how this work unfolds when communities lead.
In 2017, residents of the 15A1 and 15C communities in Villa María del Triunfo, a district in southern Lima, asked for help moving water from the bottom of their hill to the top. MEDLIFE and the communities signed an agreement: MEDLIFE provided materials for the pump system, and community members set it up together.
The solution combined several elements:
Community members connected the pumps to the tanks and checked the system along the way. The result: families no longer need to carry heavy buckets up steep steps several times a week.
In the highland community of Galte Yaguachi, in Ecuador's Guamote region, children had no bathroom at their school. They had to walk to a nearby day care center or ask neighbors. Through the community's own work, a new set of sanitary bathrooms was completed, giving students proper facilities of their own.
Where a sewage connection isn't possible, eco-bathrooms offer another path. These facilities don't need a connection to the city water system, use little to no water and can repurpose waste, for example as compost.
For students in civil, environmental or sanitary engineering, these projects turn classroom concepts into decisions with real consequences. Working under the guidance of local engineers, students can see:
Projects change based on what each community prioritizes, so the type of build varies from trip to trip. Whatever the project, students always work alongside residents and under the supervision of local architects and engineers.

You can learn how students take part in these projects on our development service learning trip.
Clean water and sanitation projects show how infrastructure shapes health, time and opportunity. They also show what community-led engineering looks like: local professionals leading the technical work and families owning the result.

They are community infrastructure projects that improve access to safe water and hygienic sanitation. Examples include water pumping and storage systems, distribution lines to homes, and bathrooms for schools and families.
An eco-bathroom is a sanitation facility that doesn't need a connection to the city water system. It uses little to no water and can turn waste into compost, which makes it useful in water-scarce communities.
Yes, when a community has prioritized that kind of project. Students work alongside residents under the supervision of local engineers, who lead design and technical decisions.
