An example from Viet Nam

UNICEF Viet Nam\Truong Viet Hung


In rural Viet Nam, 20 per cent of the population still do not have access to basic drinking water services, leading to leaving children vulnerable to diarrhea, dysentery, typhoid, and other water-borne diseases. Following Cambodia’s example, Viet Nam has invested in the production and distribution of ceramic filters to address the issue of water access, particularly in rural areas. Led by the Ministry of Agriculture and Rural Development (MARD), the National Centre of Rural Water Supply and Sanitation (NCERWASS) and UNICEF, a public–private partnership among various stakeholders was formed to test the production of ceramic filters at the pilot location in the southern province of An Giang.

Since the project's inception, over 31,000 ceramic filters have been sold on the market and over 3,200 ceramic filters have been distributed by UNICEF and its partners to schools, households, and commune health centres. On February 2018, the ceramic filter also passed quality tests administered by the National Institute of Occupational and Environmental Health under Viet Nam’s Ministry of Health. Plans are currently underway to establish a second production site and advocate for the ceramic filter production partnership model to other private businesses on the one hand and to ensure access to safe water to rural households at an affordable price.

Additionally, more than 1,139 ceramic filters are being distributed to drought/saline water intrusion-affected households in Mekong River provinces (Soc Trang and Ben Tre) to ensure access of safe water to the drought-affected households. Also, to contribute to COVID-19 prevention and control, 2,000 households, 781 schools, and 124 commune health centers have received ceramic filters for accessing
safe drinking water.
