2021 Lenten Snapshots

During the 2021 Lenten season, we’ll share the work of the Sisters of Notre Dame de Namur from around the world. We hope you in turn will share their work with your family, friends, students and faculty. If you are interested in the Lenten Handout, please click here. Click here for the Lenten prayer card.


After extensive discussion with experts in water treatment, we realized that the current ultraviolet technology alone is insufficient. Without further treatment, the water is officially considered non-potable, but accomplishes the critically important step of supplying water for treatment.

Last year, the decision was made to develop a standard prototype using ultrafiltration as the primary technology for pathogen removal, followed by ultraviolet exposure.

The ultrafiltration unit specified for the Sisters’ communities is the Antunes VZN-520H. This unit has the advantage of providing ultrafiltration for pathogen removal while retaining trace minerals that are essential to maintain human health. The unit is simple and robust, which are essential qualities for service in Congo.

The first system will be installed at Lemfu. If the system is deemed successful, it will be fabricated and deployed at all of the Sisters’ sites in Congo.

The Lemfu site was chosen for several reasons:

  • It has a small hospital.
  • It has primary and secondary schools with many students who reside in dormitories.
  • It is the closest site to the capital of Kinshasa with good road access.
