University Students in La Paz Create Innovative Device That Measures Water Pollution

Five Unifranz students formed the group ViewGreenTec two years ago and have competed in various national and international technology competitions.

Five Bolivian university students created an innovative device that measures water pollution in a precise and rapid way, allowing the monitoring of water quality in springs, rivers, and lakes. The project was born with the aim of protecting public health and has received awards in national and international technology competitions.

The developers—Ronald Choque, Daniel Escobar, José Félix Sarmiento, Aaron Huanca, and Kevin Apaza—are senior systems engineering students at Franz Tamayo University (Unifranz) in La Paz.

After forming the group ViewGreenTec two years ago, they have competed in various national and international technology contests, where they won first place.

“The project emerged due to the need for information on water quality, because the water from the springs is pure, but as it travels (through some cities) it gets polluted, and it is used for animals, washing clothes, and other purposes, which affects public health,” Choque told EFE.

How the Device Works

He explained that the device collects samples and sends them via radio frequency to a station where all the information is received. This data is stored in a database, processed, and filtered so that accurate data is eventually published on a mobile app.

The analyzed water data—such as pH level, humidity, turbidity, and amount of waste detected—is published on a cellphone. Based on this information, the app confirms that the water is “not suitable” for consumption.

The Beginnings

Daniel Escobar told EFE that they built the prototype several years ago, and the first versions “absolutely” required power from computers and other devices. It also operated using wooden containers, which caused moisture.

“Now it runs directly on rechargeable, non-polluting batteries, and we’ve also managed to cover long distances. The device no longer needs the internet; the radio frequency sends the data,” said Escobar.

ViewGreenTec’s work has already had its first impacts. Data showing that the water from a stream near the municipality of Viacha, in the highlands of La Paz, was “not suitable” for consumption was presented by local residents to the municipal government. As a result, municipal authorities carried out a cleanup of the area.

Looking Ahead

José Félix Sarmiento noted that “while it is a small-scale device,” the future goal is for the project “to become professional, creating more complementary modules that can be adapted to rivers, rain, and more extreme environmental conditions.”

Aaron Huanca shared that the device won first place at a technology fair organized by Unifranz, as well as in a NASA Space Apps Challenge held in the city, which motivated them to refine the device. The group also ranked among the top entries in an international competition.

This device is part of Franz Tamayo University’s integrative projects, in which students must propose initiatives based on socially impactful solutions using new technologies and teamwork.

The five developers hope to eventually establish ViewGreenTec as a company, generate impact at various levels of Bolivian society, and are also working on other devices to measure ultraviolet radiation and air pollution.
