Facility Modules

Purdue University Facility Filter Unit in Las Canas, Dominican Republic
    An interdisciplinary service-learning class was initiated at Purdue University in the Fall 2012.  Its objective was to design, build, and implement community-scale water treatment systems for communities in a developing country. For the foreseeable future, target communities will be in the Dominican Republic (DR).  Work on this project has involved coordination with Aqua Clara International and with the DR principals of the Safe Water Institute and local members of  Rotary International who have been helpful in identifying potential target communities and in connecting the project team to community leaders in the DR.
    Based on communications with project partners, the town of Las Canas, DR was selected as the location for a pilot system.  It is anticipated that the lessons learned in implementing the system at Las Canas will allow for other, similar systems to be designed, built, and implemented in other communities in the DR, and perhaps in other countries.
    This new system, which was constructed at the Ana Julia School in Las Canas, was designed to provide safe water to children and teachers at the Ana Julia School, and to allow residents of Las Canas to purchase safe water at an affordable price.
    The students and their faculty advisors started this project in August 2012 with the idea that the first system (the Las Canas system) would be a pilot effort, in the sense that they plan to use the lessons learned in Las Canas to inform design and implementation of similar systems for other communities in the DR.  This interdisciplinary service-learning class will be continued in the

Water tanks as installed at the Ana Julia School.  Water that has passed through the sand filter and the microfiltration system is directed to these two tanks.  Chlorine is added as liquid chlorine bleach to each tank.  As such, finished water is produced in a batch mode of operation.

Schools of Managua, Nicaragua 

In October of 2013, a team of ACI traveled to several parts of Managua to install 13 Facility Units in 12 schools thanks to the help of World Wide Christian Schools. The largest school was in an area called Tipitapa. ACI built two Facility Filter Units in two different areas which supplies 3000 students with potable water.

The Ranch – Los Alpes, Leon, Nicaragua

The Eco-lodge Rancho Los Alpes near Leon in Nicaragua is an active conference center and also serves as the base camp for Aqua Clara Teams working in the area.  As with many locations in the country, the ranch has no potable water.  The well that serves the ranch is contaminated with e-coli and other bacteria from sources including waste from area farm animals.   Electricity in the area is limited and somewhat unreliable.  The ranch must pump water from the well into a holding tank mounted on the roof of one of the ranch buildings.  The water is then piped to the ranch buildings for use in showers, laundry, livestock and landscape plant watering.  To relieve the ranch staff of the need to transport potable water a two-filter .02 micron hollow fiber bank was fabricated and installed by ACI team members from Nicaragua and the United States during May 13-26, 2012 .

Because the water at the ranch has very low turbidity year round the filter installed used a 15 micron cartridge filter in place of the normal sand bed filter to precondition the water.  To provide filtered potable water to the ranch the team tapped into existing water piping that ran near the kitchen.  The filter bank was fabricated and a support structure was constructed from local lumber. A line of filtered water was piped into the ranch kitchen to a faucet in the sink area.   To prolong the filter operation, the hollow fiber filters must be cleaned by back washing daily with potable water.  Drain lines were installed so that water from cleaning the hollow fiber filter cartridges is used to irrigate landscape plantings in the area.  Finally, ranch staff were trained on how to perform the valving manipulations required for the daily hollow fiber filter backwashing.

 Installed Facility Filter by ‘Hope For the Masai’ in Tanzania

After a training performed by Paul Kaufman, in February of 2014, our partnered on-the-ground NGO in Tanzania, ‘Help for the Masai’, installed a Facility Filter Unit in the rural town of Orbili.  It is located in South Masai land and is very rural.  The filter is placed in a school/community center that was built by a local Masai NGO called MAPED.
