Did you know? An estimated 2.3 billion people lack access to improved sanitation – defined as facilities that hygienically separate human excreta from human contact.  In fact, the World Health Organization (WHO) estimates that nearly 850,000 people in low- and middle-income countries die each year as a result of inadequate clean drinking water, sanitation and hygiene.WHO/UNICEF 2015


In the African nation of Uganda, many people in rural areas and even the outskirts of major cities rely on pit latrines or outhouses as their bathrooms.  Some of these pit latrines serve individual families or a cluster of families.  In the more rural areas they can be used by entire communities. The excrement and contaminated water that gathers in the pits not only produces a foul odor, but also creates a breeding area for flies, mosquitoes, cockroaches and other insects that can infect humans with potentially fatal illnesses.

To address this vital issue, Lonza’s Water Treatment business based in South Africa is teaming up with the NGO Clean Habitat Uganda to provide HTH Scientific® Pit Latrine Sanitizer Tablets for use in treating pit latrines that serve schools, families and communities in two identified areas of Uganda.  The tablets, which are manufactured in Lonza’s calcium hypochlorite facility in Kempton Park, Republic of South Africa, provide multiple benefits:

  • Kill germs that can make people ill
  • Help reduce insect larvae
  • Combat the spread of viruses
  • Reduce bad smells

Health authorities, family members and communities will be instructed in the safe storage and use of the tablets, such as assuring that there is some water  -- such as water that had been used for washing utensils or clothes  -- in the pit before any tablets are dropped in.


Lonza has committed to support the provision of the HTH Scientific® Pit Latrine Sanitizer Tablets and needed financial support for at least three years.  At Lonza, we make products that enhance the quality of life.
