We improve access to clean water by promoting and distributing point-of-use household water treatment products.
Our household water treatment programs improve water quality where they are needed most, and integrate water programming with hygiene and sanitation interventions when possible.
Household water treatment improves the quality of drinking water by using chlorine-based solutions that are effective, easy-to-use and inexpensive. We distribute three different chlorine products: safe water solution (liquid), chlorine tabs and Procter & Gamble’s Purifier of Water (powder).
Safe Water Solution
Safe water solution is a dilute sodium hypochlorite (chlorine) solution used to disinfect water at the household level. One capful of solution treats about 20 liters of water, about the size of most containers used to obtain and store water. The solution is easy to use and extremely inexpensive — a bottle typically costs less than thirty cents to protect a family of six for one month.
We market and distribute safe water solution in 18 countries and have become the largest distributor of the product in the world. The solution is locally manufactured, providing business and wages for the local private sector, improving sustainability of the program and reducing production costs. The product is most commonly distributed under the brand names Waterguard or Sur’Eau.
Water Treatment Tablets
Chlorine tablets are water purification tablets that have an effervescent base comprised of pharmaceutical and food grade compounds. Each tablet treats 20 liters of water and can be sold in small quantities (typically strips of ten individually sealed tablets), allowing consumers with minimal disposable cash to afford safe drinking water for their families. As a tablet is dissolved, chlorine is released, disinfecting the water and preventing water-borne diseases. Chlorine tablets are most commonly distributed under the brand name Aquatabs.
P&G Purifier of Water
Developed by Procter and Gamble (P&G) in collaboration with the Centers for Disease Control, the P&G Purifier of Water is a robust household water treatment technology. The product is a powder packaged in 4 gram sachets. Each packet treats 10 liters of water. Using the combined process of disinfection with calcium hypochlorite and flocculation with iron sulfate, the product kills bacteria and viruses and removes turbidity (dirt) and parasites. This is the same technology utilized by municipal water treatment facilities, and is also effective in removing cysts, arsenic and pesticides like DDT. Because of the product’s efficacy in visibly removing dirt and chlorine-resistant parasites from water, we often target P&G Purifier of Water to people living with HIV/AIDS and to those drinking turbid surface water.
Making a difference
In collaboration with the local government in Myanmar, USAID, Procter and Gamble (P&G) and PSI celebrated the launch of an innovative partnership to deliver over 10 million sachets of P&G Purifier of Water.
