  Cost-effective and Appropriate Sanitation Technologies, India

Sulabh International Social Service Organisation, a pioneering non-governmental organisation in promoting environmental sanitation since over three decades within India and abroad, established an affordable, appropriate, indigenous and culturally acceptable solution to safe sanitation. The system is

never out of commission, can be built with locally available materials, easy to maintain and has the potential for up-gradation. The approach has also combated the problem of manual scavenging.

  Water Purification and Bottling, India
The Byrraju Foundation, a non-profit organization, has embarked upon providing safe drinking water conforming to WHO standards to the villages in the State of Andhra Pradesh, India. The Foundation separates ‘safe drinking water for everyone’ from the rest of the water supplied through Rural Water Supply Scheme in the villages, by treating the water in a small plant with appropriate and effective technology, which produces 1000-2000 liters of pure drinking water in one hour. This water is free from harmful bacteria and other impurities and is delivered in 12-litre HDPE food-grade Cans at a user charge of approximately US$ 0.04 at Plant with which the unit can function on a sustainable basis and is affordable to the common man.
  Simple Solution for Drinking Water makes a Big Difference, Indonesia
The people in Jakarta, Indonesia no longer have to boil water for drinking. A new and easy-to-use water treatment solution, "Air Rahmat" meaning "Gift Water," gave a breakthrough in water purification technology. The system decontaminates water for drinking, and reduces health risks. A common 19-liter bottled water costs one U.S. dollar while a 100-milliliter bottle of Air Rahmat, is enough to treat approximately 660 liters of water. The average amount spent in a month by a household of four members is less than 50 cents.
  Rainwater Harvesting – A Viable Option, Kathmandu Valley, Nepal
UN-HABITAT in partnership with the Government of Nepal and local NGOs initiated a programme to build capacities on Rain Water Harvesting (RWH) system and to disseminate, demonstrate and promote RWH technology in Nepal. A Rainwater Harvesting Promotion Programme was launched in five municipalities of Kathmandu Valley and Banepa Municipality in January 2006, which aimed at familiarizing people with this simple technology of tapping nature’s gift and popularize its use at the household, community and municipal levels and thereby provide a supplementary water source to the people.
  Removable Technology for Arsenic and Microbiological Contamination, Nepal
Kanchan Arsenic Filter (KAF), a household water filter, provides a sustainable solution to the arsenic and microbial contamination of drinking water in Nepal. The design of KAF is optimized based on the socio-economic conditions and predominance of arsenic content in the regions. Studies have revealed high user acceptance, financial sustainability, excellent technical performance. The users and NGOs in Nepal consider the KAF is the best among all the available household arsenic filters.
  Water Treatment Systems at Household level, Nepal
The Municipal water supplies in Nepal rarely chlorinate to an adequate level and bacterial contamination in tap water is common, resulting in a high incidence of water-borne diseases. Common practices are simply to cover the water vessels to protect the water from contamination. Boiling, filtering and using chemical disinfectant are the commonly used techniques in the households. These treatment systems have limitations. Raising awareness of the issues and promoting household water treatment options or point-of-use drinking water treatment play a vital role in ensuring access to safe and clean drinking water.
  Big Results from Small Solutions: Decentralized Wastewater Management, the Philippines
Tourism contributes significantly to the economy of Liloan, a costal town in the province of Cebu, the Philippines. When water pollution due to poor sanitation threatened the tourism industry, ADB provided assistance to eradicate the problem, through demonstration activities and grant for the Water Sector. A decentralized wastewater treatment facility was established using local technology. The results were outstanding and financially promising. The coastal waters have become clearer and contamination has completely receded.
  Technology Turns Water Weakness into Strength, Singapore
Singapore was water-dependent on Malaysia prior to its independence in 1965. Singapore’s innovative interventions have made the country self-sufficient after its independence by combining frontline technology with demand management. The NE Water, produced from the recycling of the used-water and supplied as drinking water in bottles, has not only gained wide support and acceptance of the Singaporeans, but it has also kept the unaccounted-for water low. The desalination plant is capable of producing daily potable water at 46 U.S. cents a liter to Singapore’s four million citizens.
