Dotro G., Langergraber G., Nivala J., Puigagut J., Stein O.R., Von Sperling, M. (2017) Biological Wastewater Treatment Series Treatment Wetlands

Treatment wetlands are natural treatment technologies that efficiently treat many different types of polluted water. Treatment wetlands are engineered systems designed to optimise processes found in natural environments and are therefore considered environmentally friendly and sustainable options for wastewater treatment. Compared to other wastewater treatment technologies, treatment wetlands have low operation and maintenance (O&M) requirements and are robust in that performance is less susceptible to […]

This fact sheet seeks to address potential concerns and barriers regarding LID techniques, compared to conventional stormwater management practices.

WHO (1991) Surface water drainage for low income communities

Many low-income communities in developing countries consider stormwater dra inage to be their most urgent need as far as urban infrastructure is concerned. This is partly because their houses are often built on unsuitable land. In areas sufficiently close to the city centre for the journey to work to be affordable, land prices tend to be beyond their means. The only land they can afford, […]

Bjerregaard, M., Meekings, H. (2008) Low cost drainage for emergencies

Effective drainage is important in emergencies when there is a risk of flooding or there is a risk of poor environmental health conditions developing from standing water, muddy conditions, or erosion. It would not usually be the first priority in the initial stages of an emergency, but should be considered after the immediate water, sanitation and hygiene needs have been met. Sites which have natural […]

Mara, D. D., Sleigh, A., Tayler, K. (2001) PC-Based Simplified Sewer Design

Simplified sewerage is an important sanitation option in peri-urban areas of developing countries, especially as it is often the only technically feasible solution in these high-density areas. It is a sanitation technology widely known in Latin America, but it is much less well known in Africa and Asia. It is the purpose of this Manual to disseminate this technology more widely in the developing world, […]

EPA (2002) Collection Systems Technology Fact Sheet Sewers Conventional Gravity

Sewers are commonly referred to according to the type of wastewater that each transports. For example, storm sewers carry stormwater; industrial sewers carry industrial wastes; sanitary sewers carry both domestic sewage and industrial wastes. Another type of sewer, known as a combined sewer, is prevalent in older communities, but such systems are no longer constructed. Combined sewers carry domestic sewage, industrial waste, and stormwater. This […]

Malambo, D. (2014) Sanitizing Faecal Sludge using Lactic Acid Bacteria in Emergencies

Providing safe excreta collection and disposal in emergency situations has remained one of the most urgent priorities in the disaster relief effort. This is because of the high risk to human health that exposed and unsanitized human excreta pose. With an increase in the frequency and intensity of natural disasters in recent years, humanitarian aid and related organisations worldwide are currently exploring sustainable low cost […]

Ligocka, A., Paluszak, Z. (2004) Capability of lactic acid bacteria to inhibit pathogens in sewage sludge subject to biotechnological processes.

The investigation included 30 isolates of lactic bacteria originating from different sources (composted green materials, EM “Greenland” preparation as well as Lactobacillus brevis and L. plantarum cultures), and the following pathogens: Salmonella sp., Listeria monocytogenes, L. innocua, Escherichia coli, Streptococcus faecium, Staphylococcus aureus, Pseudomonas aeruginosa, Proteus mirabilis and Bacillus cereus. Lactic bacteria were inoculated pointwise and incubated under anaerobic conditions, then covered with a layer […]

González P., M. E. (2014) Sanitising faecal sludge with ammonia (from urea) in the context of emergency situations Master thesis

In an emergency situation, the collection, treatment and disposal of the human excreta and waste in a safe way is one of the biggest challenges to face, regardless the type of disaster. When it comes to faecal sludge management, the traditional desludging methods can often not be appropriate in an acute emergency phase. Consequently, relief organisations aim to apply new and simple approaches and modular […]

Nordin, A., Nyberg, K., Vinneras, B. (2009) Inactivation of Ascaris Eggs in Source-Separated Urine and Feces by Ammonia at Ambient Temperatures

Sustainable management of toilet waste must prevent disease transmission but allow reuse of plant nutrients. Inactivation of uterus-derived Ascaris suum eggs was studied in relation to ammonia in source-separated urine without additives and in human feces to which urea had been added, in order to evaluate ammonia-based sanitation for production of safe fertilizers from human excreta. Urine was used concentrated or diluted 1:1 and 1:3 […]

USAID (2015) Implementer’s Guide to Lime Stabilisation for Septage Management in the Philippines

Local government units (LGUs) just beginning to implement a new septage management program may wish to phase in the program over time. Lime stabilization can be done as a first phase following a disaster and perhaps serve the public and commercial sectors. In the next phase, a municipal or city-wide program to desludge all septic tanks on a regular schedule using treatment technologies besides lime […]

Sozzi, E., Fesselet, J. F., Taylor, H. (2011) Standard operating procedure for the physicochemical treatment of CTC wastewaters

When cholera strikes in a low-income country, the rapid construction and successful operation of specialist cholera treatment centres (CTC) by medical NGOs can significantly reduce the mortality rate. Such has been the case in Haiti. Since cholera struck the eastern part of the island of Hispaniola in October 2010, in the aftermath of a devastating earthquake ten months earlier, Médecins Sans Frontières has operated five […]

Chakraborty I., Capito, M., Jacks, C., Pringle R. (2014) Household-level application of hydrated lime for on-site treatment and agricultural use of latrine sludge

Rural areas of Cambodia have no safe waste management strategies for household latrine waste. Household application of lime (calcium hydroxide, Ca(OH)2) would enable households to treat waste easily on-site and significantly reduce the risk of latrine sludge causing negative impacts on human health and the environment, whilst transforming latrines into incubators of a valuable agricultural additive. Initial investigative work – including human centered design research, […]
