A septic tank takes raw sewage in, allows the solids to settle (sludge) and allows the remaining liquid to flow into the surrounding soil by means of a soakaway. Scum on the surface is also prevented from leaving the tank. Microorganisms in the anaerobic environment in the tank digest the sludge and... scum. The system consists of several stages, supply to the tank, the tank itself and the soak field.

Yemen remains the world’s worst humanitarian crisis with staggering levels of humanitarian need. Eighty per cent of the population – 24.1 million people – need some form of humanitarian assistance. Economic decline, restrictions on imports, shortages of foreign exchange and liquidity, and fluc...tuations in the value of the currency continues to put millions of people at risk of famine. Key assessments remain blocked, complicating efforts to adjust programmes based on the latest evidence. This makes it difficult to know with certainty whether there are large pockets of unmet needs across the country.

The Guideline for Disinfection and Sterilization in Healthcare Facilities, 2008, presents evidence-
based recommendations on the preferred methods for cleaning, disinfection and sterilization of patient-
care medical devices and for cleaning and disinfecting the healthcare environment. This docume...nt
supercedes the relevant sections contained in the 1985 Centers for Disease Control (CDC) Guideline for
Handwashing and Environmental Control. 1 Because maximum effectiveness from disinfection and
sterilization results from first cleaning and removing organic and inorganic materials, this document also
reviews cleaning methods. The chemical disinfectants discussed for patient-care equipment include
alcohols, glutaraldehyde, formaldehyde, hydrogen peroxide, iodophors, ortho-phthalaldehyde, peracetic
acid, phenolics, quaternary ammonium compounds, and chlorine. The choice of disinfectant,
concentration, and exposure time is based on the risk for infection associated with use of the equipment
and other factors discussed in this guideline. The sterilization methods discussed include steam
sterilization, ethylene oxide (ETO), hydrogen peroxide gas plasma, and liquid peracetic acid. When
properly used, these cleaning, disinfection, and sterilization processes can reduce the risk for infection
associated with use of invasive and noninvasive medical and surgical devices. However, for these
processes to be effective, health-care workers should adhere strictly to the cleaning, disinfection, and
sterilization recommendations in this document and to instructions on product labels.

The UN’s SDG Stimulus Plan, which calls for additional liquidity, effective debt restructuring and the expansion of development financing, has the potential to free up significant fiscal space in developing economies. For 52 most debt-vulnerable economies, a 30 percent haircut of 2021 public exter...nal debt stock could lower debt service payments in 2022–2029 by between US$44 billion and $148 billion, depending on the participation of various creditor classes. For all developing economies, a 40 percent “refinancing” of their 2021 bond debt stock to average official creditor rates could amount to a $121 billion savings on interest payments in 2022–2029. Against the backdrop of growing economic and geopolitical fragmentation, this policy brief describes building blocks for exiting the crisis.
