Electricity was installed in 2012 at Brother Paulin, clearing the way for Tek4Kids to install a water purification system for the students. Tek4Kids installed eight batteries to power the water system, which pumps 1000 gallons of city water each week through the cistern and increases the pressure used to push the water through the cistern.
In 2012, Tek4Kids mounted two distribution tanks and two treatment tanks on the roof of Brother Paulin. It took several men to hoist the tanks to the roof of the school. In 2014, a water jug fill station was added for students to take clean water home to their families in an effort to stop the spread of waterborne diseases.
