CASE STUDY
ENVIRONMENTAL TECHNOLOGY IN THE DEVELOPING
WORLD
With recent initiatives of ceramic filters in the home and
chlorination at the plant, Communidad Connect urged us to assess
the water quality and effectiveness of their chlorination method of
the town through microbial contamination analysis and residual
levels of chlorine in the drinking water.
THE TEAM
The Yale University team includes: Jaehong Kim PhD.,
Evan Doyle ’17, Eva Albalghiti ’17, Theodore Agbi ’17,
Kamya Jagadish ’16, Adam Sokol ’17, Tanya Shi ’17, Anna
Hagstrom (Graduate Assistant), Stephanie Loeb
(Graduate Assistant).
BACKGROUND
We ventured on a 4 day project based in Los Robles,
Nicaragua intending to use the DelAgua Kit. Los Robles
has taken the issue of clean water head on. The
Brigadistas, 13 women fighting for public health, has
been at the forefront of this fight helping to organise the
water treatment plant that now delivers approximately 2
million gallons of water a month to the community. From
laying the piping system to organising the volunteer
based maintenance of the system, the Brigadistas
alongside the NGO Comunidad Connect has progressed
the issue of clean water.

We chose to use the DelAgua unit for its easy to use and versatile
mobile design. We designed a project that would test water at
various points along the distribution network to assure the
chlorine was effective throughout the network. In order to get
accurate microbial counts from various water samples we not only
varied our sampling points, but also intended to test microbial
counts before and after the planned installation of our new
chlorine injector system.
Finally, to help quantify the efforts of the Brigadistas we aimed to
use the DelAgua unit to understand quantitatively how much safer
the water was to drink after being filtered through local clay and
ceramic filters.
We are all so grateful for the innovations at DelAgua that make
projects like this possible.
