AHD celebrated world water day in 15 villages / areas and AHD Nadi filter promoted during awareness and training in 15 villages. about 375 Nadi filter units promoted in poor communities to have access to safe and clean drinking water at household level
Association for Humanitarian Development (AHD) is a non governmental organization established in December 2001-2002 & registered under societies Act XXI of 1860 on May 17th 2003, with the major objective to work for peace, justice, harmony, and equality through participation of the most disadvantaged and marginalized communities for the sustainability. AHD has initiated several livelihood and development programs by targeting rural women & children. The major accomplishment in this regard, is the introduction of Bio-Sand Water Filter (BSF) / Nadi Filter in 36,000 families Sindh & Pakistan to provide access of poorest communities to safe drinking water. AHD’s BSF Project is known as Nadi Filter (local name), because Nadi (a mud pot, 32-34 inches tall) is commonly used by local community in household for water storage purposes .
The innovation made with major objective of using limited available resources, particularly commonly used mud pots for water storage (such as; Nadi) in rural household for filtration that could sustained itself, without any external interventions. In support of this initiative, project by following participatory approach, focuses on mobilization of communities, formation of community groups, construction, installation & maintenance of filter and follow-up trainings in use of the filter, safe water practices & hygiene and sanitation.
Nadi filter technology project supported by national & international donors: Misereor Germany, UNEP-APFED, ADP & Oxfam GB, CDP Govt. of Sindh, Global Giving, & individual donors. Under the project AHD has installed more than 36,000 Nadi filters during the past 8 years 2006-2015, providing life-sustaining water to more than 360,000 people, who are living in rural communities now drinking clean and safe water at their household level.
Nadi Filter (Bio Sand Water Filter / BSF)
Bio-Sand Water Filters (BSF) are a technological adaptation of the centuries old slow sand filtration process. It is not a newly developed technology, several commercial and community-scale implementations exist in different countries. The largest use of BSF technology has been in the humanitarian arena. But in coastal areas of Sindh, it is first time to take such initiative at household level by AHD. Technology and method exist to bring improved water and sanitation practices to even the most remote areas. It’s an affordable, sustainable household technology, proven to be very effective in improving the quality of water to make it safe for drinking, cooking, bathing, and cleaning.
The average cost of a Nadi filter, which normally serves a household of 8-10 people is only Rs 1,000-1,500/=. That includes the cost of material, installation, transportation, the cost of training on the filter operation/maintenance and important health and hygiene education. BioSand Filters remove 95.0 to 99.0% of organic contaminants, including bacteria, viruses, protozoa, worms, and particles. Safe water produced by the filters is free of discoloration, odor, and unpleasant taste. The most common home-based models can produce between 5 to 10 liters of water per hour but Nadi filter can produce 30 to 40 liters of water per hour.
