New call for tenders – WSUP

Strengthening public finance for urban sanitation services in Mozambique

It is estimated that poor sanitation costs Maputo’s residents over US$ 7.4 million annually as a result of access time lost, premature deaths, productivity losses due to sickness, and health care costs. The majority of the population relies on on-site sanitation, 28% on septic tanks, and 28% on improved latrines. Many of these systems are emptied by mechanical and manual private operators paid for by households themselves, the total value of which is unknown but thought to be significant. The remainder of the population, over 30%, have access to a non-improved latrine. It is this latter section of population that is most negatively and disproportionally impacted by poor sanitation.

In December 2016, a new sanitation surcharge was approved by CMM (Municipal Council of Maputo), with plans for implementation in 2017. WSUP intends to support CMM in the implementation of the surcharge and introduction of eligible sanitation services. CRA (Conselho de Regulação de Águas, the national water and sanitation regulator) and WSUP intend to undertake a 6 month research project to capture learning from the implementation of previous activities in Maputo, and the replication by CRA in Beira and Quelimane. This includes a documentation of the process, an assessment of the sanitation surcharge, regulatory framework agreement and compliance with the agreement (transfers and investments).

Consultancy objective:
The overall objective of this consultancy is to strengthen CRA’s capacity to more effectively and equitably mobilise public finance into urban sanitation services in Mozambique. More specifically, the objectives are:

1. adapt tools and strengthen capacity to model financial cost of delivering sanitation services in urban centres of Mozambique, and
2. strengthen CRA’s regulatory mechanisms, tools and oversight to ensure more effective and equitable sanitation service delivery in Mozambique.

Bids due: Before 23:59 (GMT +2) on 22nd March 2018
Location: Desk and Mozambique
Start date of consultancy: 30th March 2018
End date of consultancy: 18th September 2018

More information and details of how to apply can be accessed on the WSUP website (‘Current research calls’).

Toward a Hygienic Environment for Infants and Young Children: A Review of the Literature – USAID/WASHpals

Toward a Hygienic Environment for Infants and Young Children: A Review of the Literature. USAID Water, Sanitation, and Hygiene Partnerships and Learning for Sustainability (WASHPaLS), February 2018.

 For nearly six decades, the routes of pathogen transmission from human excreta to a new host have been reflected in the seminal “F-diagram” via fluids, fingers, flies, fields (floors, earth, dirt), and fomites (surfaces).

The WASHPaLS project conducted a review of the scientific and grey literature, complemented by dozens of key informant interviews with researchers and practitioners, to re-examine the F-diagram, highlighting the underemphasized sources of pathogens and transmission pathways that are of particular relevance to the health of infant and young children (IYC) and not disrupted by the traditional suite of WASH measures.

These are:

  • domestic animal excreta as a source of risk, and
  • direct ingestion of pathogens via eating feces, dirt (geophagy) or through mouthing behaviors as additional pathways.

Research updates from the SHARE project

Below are links to 2017 and 2018 articles from the SHARE project

Oral Contact Events and Caregiver Hand Hygiene: Implications for Fecal-Oral Exposure to Enteric Pathogens among Infants 3–9 Months Living in Informal, Peri-Urban Communities in Kisumu, Kenya – Childhood diarrhea is one of the leading causes of morbidity and mortality in children under five in low and middle-income countries, second only to respiratory illness. The mouthing behavior that is common in children exposes them to fecal-orally transmitted pathogens that can result in diarrhea; however, there is a need for further evidence on specific exposure routes. This study describes the frequency and diversity of two important routes of enteric pathogen exposure among infants 3–9 months of age: infant oral contact behavior and caregiver handwashing behavior. The combined implication of data from observing oral contact behavior in children and hand hygiene of caregivers suggests that caregiver hand hygiene prior to feeding events and after cleaning a child are priority interventions.

From menarche to menopause: A population-based assessment of water, sanitation, and hygiene risk factors for reproductive tract infection symptoms over life stages in rural girls and women in India – Women face greater challenges than men in accessing WASH resources to address their daily needs, and may respond to these challenges by adopting unsafe practices that increase the risk of reproductive tract infections (RTIs). WASH practices may change as women transition through socially-defined life stage experiences, like marriage and pregnancy. Thus, the relationship between WASH practices and RTIs might vary across female reproductive life stages. This cross-sectional study conducted by Baker et al. assessed the relationship between WASH exposures and self-reported RTI symptoms in 3,952 girls and women from two rural districts in India, and tested whether social exposures represented by reproductive life stage was an effect modifier of associations.

Estimating the Health Risk Associated with the Use of Ecological Sanitation Toilets in Malawi – Main exposure pathways were through poor storage of sludge, contamination of foods during drying, walking barefoot on the ground contaminated with sludge, pit emptying without protection, and application of sludge in the fields. Estimated annual risk for Ascaris lumbricoides, Taenia, and hookworms was approximately over 5.6 × 10−1 for both Fossa Alternas (FAs) and Urine Diverting Dry Toilet (UDDTs). Risk from E. coli and Salmonella was 8.9 × 10−2 and above. The risks were higher than WHO acceptable risk for use of faecal sludge in crops of 10−4 infections per year. Promoters and users of EcoSan latrines need to consider advocating for strict guidelines to reduce the risk.

Role, ownership and presence of domestic animals in peri-urban households of Kisumu, Kenya – The research demonstrates the high prevalence of animal ownership in a low-income and high-density peri-urban neighbourhood of Kisumu, which may facilitate zoonotic disease transmission. Further research should assess if and to what extent animal ownership in such communities is associated with disease risk.

High prevalence of ESBL-Producing E. coli in private and shared latrines in an informal urban settlement in Dar es Salaam, Tanzania – Almost a quarter of private and shared latrines in an informal urban settlement in Tanzania are contaminated with ESBL-producing microorganisms, suggesting a high prevalence of human ESBL faecal carriage in the community. Shared latrines may serve as a reservoir for transmission in urban community settings in Tanzania.

Contributing to the debate on categorising shared sanitation facilities as ‘unimproved’: An account based on field researchers’ observations and householders’ opinions in three regions, Tanzania – Having an ‘improved’ latrine remains important as JMP recommends, but based on our study findings, we argue that possessing a non-shared latrine neither guarantees safety to its users nor its categorisation as ‘improved’. Instead, the state of the latrine, the construction technology used and the behaviours of the users may be more important.

Immunogenicity of rotavirus vaccine (RotarixTM) in infants with environmental enteric dysfunction – Deployment of rotavirus vaccines has contributed to significant declines in diarrheal morbidity and mortality globally. Unfortunately, vaccine performance in low-middle income countries (LMICs) is generally lower than in developed countries. The cause for this has been associated with several host and maternal factors including poor WASH status, which are predominant in LMICs. More recently, environmental enteric dysfunction (EED) has specifically been hypothesized to contribute to poor vaccine uptake and response. The aim of this study was to examine the association between serological biomarkers of EED and seroconversion to rotavirus vaccine in Zambian infants.
