CWIS TA-Hub (2021) SANIMAS - Final Report Independent Evaluation of SANIMAS Model as an Approach for Providing Decentralised Sanitation
According to RPJMN 2020–2024 figures, in 2018 almost 75 percent of the Indonesian population has access to improved sanitation nationally. This includes almost 7.5 percent classified as safely managed sanitation services based on Sustainable Development Goals (SDGs) 2030 definitions. These figures are impressive considering the low base of sanitation coverage with which the country has been evolving from.

EPA (2006) Ultraviolet Disinfection Guidance Manual for the Final Long Term 2 Enhanced Surface Water Treatment Rule
Interest in using ultraviolet (UV) light to disinfect drinking water is growing among public water systems (PWSs) due to its ability to inactivate pathogenic microorganisms without forming regulated disinfection byproducts (DBPs). UV light has proven effective against some pathogens, such as Cryptosporidium, that are resistant to commonly used disinfectants like chlorine. The United States Environmental Protection Agency (EPA) developed the Long Term 2 Enhanced Surface […]

Reed, B., Bevan, J. (2014) Managing hygiene promotion in WASH programmes
Managers of water, sanitation and hygiene (WASH) programmes normally acknowledge that people need to behave in a hygienic manner to protect water supplies and ensure that sanitation facilities are used properly. However, promoting hygienic behaviour differs from the construction of infrastructure, with indicators of progress being less concrete. This means campaigns need to be planned and carried out in a suitable manner. A number of studies […]

The proposed chapter addresses a comprehensive overview of the history and future outlook of ultrafiltration/microfiltration (UF/MF) membrane for desalination water pretreatment. Known theories on UF/MF membrane formation from phase inversion (Dr/wet) systems can be prolonged to define the consequences of high or low molecular weight additives. Also, direct material reengineering and surface modification for high-performance anti-fouling of UF/MF membranes are also highlighted. Before the modern […]
