Tek4Kids began building the pump house and the roof to the existing cistern with the help of our local construction crew in 2010. Piping was routed from the cistern into the pump house and through the water purification system. This system filters and chlorinates the impure water by means of a chlorine generator using ordinary salt and electrolysis powered by a 12 volt battery. The system has been purifying water for 1 1/2 years and it provides between 500 and 1000 gallons of water for the school every day. The school children are also able to bring jugs of clean drinking water home to their families. Since schools are often the heart of communities, this is an enormous help to a huge number of people. For the families of St. Therese Montessori School, this is often the only affordable possibility to obtain safe drinking water. Because of the existing water purification systems a German non-profit has installed a bathroom facility and Tek4Kids is currently providing water for this system.
