“…Improved water supply and sanitation provide individuals with increased comfort, safety, dignity, status and convenience; along with broader impacts on the environment [ 63 ]. The social welfare impacts are difficult to quantify with certainty, given their subjective nature.…”

Safe drinking water, sanitation, and hygiene (WASH) are fundamental to an improved standard of living. Globally, 91% of households used improved drinking water sources in 2015, while for improved sanitation it is 68%. Wealth disparities are stark, with rural populations, slum dwellers and marginalized groups lagging significantly behind. Service coverage is significantly lower when considering the new water and sanitation targets under the sustainable development goals (SDGs) which aspire to a higher standard of ‘safely managed’ water and sanitation. Lack of access to WASH can have an economic impact as much as 7% of Gross Domestic Product, not including the social and environmental consequences. Research points to significant health and socio-economic consequences of poor nutritional status, child growth and school performance caused by inadequate WASH. Groundwater over-extraction and pollution of surface water bodies have serious impacts on water resource availability and biodiversity, while climate change exacerbates the health risks of water insecurity. A significant literature documents the beneficial impacts of WASH interventions, and a growing number of impact evaluation studies assess how interventions are optimally financed, implemented and sustained. Many innovations in behavior change and service delivery offer potential for scaling up services to meet the SDGs.

“…Furthermore, improved sanitation has great positive impacts on children's health, gender equality, environmental sustainability, and water resources (clean drinking water). Improved sanitation would contribute both directly and through the various pathways to development, to lifting populations out of poverty, as well as preventing them from slipping back into poverty (Hutton et al, 2008).…”

Adequate provision of water, sanitation and hygiene (WASH) facilities are supporting pillars of healthy living. Hence, this review was aimed at the assessment of the status of WASH services in sub-Saharan Africa. The study used secondary data, sourced from the Joint Monitoring Programme (JMP) report by UNICEF and WHO (2015). This data was used to assess the WASH status of sub-Saharan Africa. Other information highlighted in the paper were obtained from existing literature, in peer reviewed journals, conference proceedings, commissioned studies and the internet. Data obtained were presented in tables and further analyzed using percentages. The review revealed that WASH services are poorly provided in sub-Saharan Africa, with negative consequencies on the health and socioeconomic development of people who have poor access to WASH services. Some of the reasons that have led to the poor provision of WASH services in the region are broadly classified into natural and human-related. The natural causes are the region's extreme climate and rainfall variability, which has been made worst by climate change, resulting in desertification, shrinkage of some water bodies and growing water scarcity; while the human-related causes include, poor governance, weak institutions, poor financing, and corruption in the WASH sector, amongst others. The study recommends the adoption of a comprehensive, inclusive and integrated WASH strategy that fit the peculiarities of each country in the region. This would help in maximizing the benefits of WASH services and the promotion of healthy living in the region.

Absence of wastewater and solid waste facilities impacts the quality of life of many people in developing countries. Implementation of these facilities will benefit public health, water quality, livelihoods and property value. Additional benefits may result from the potential recovery of valuable resources from wastewater and solid waste, such as compost, energy, phosphorus, plastics and paper. Improving water quality through implementation of wastewater and solid waste interventions requires, among others, an analysis of i) sources of pollution, ii) mitigating measures and resource recovery potentials and their effect on water quality and health, and iii) benefits and costs of interventions. We present an integrated approach to evaluate costs and benefits of domestic and industrial wastewater and solid waste interventions. To support a policy maker in formulating a cost-and environmentally effective approach, we quantified the impact of these interventions on 1) water quality improvement, 2) resource recovery potential, and 3) monetized benefits versus costs. The integration of technical, hydrological, agronomical and socioeconomic elements to derive these three tangible outputs in a joint approach is a novelty. The approach is demonstrated using the heavily polluted Indonesian Upper Citarum River in the Bandung region. Domestic interventions, applying simple (anaerobic filter) technologies, were economically most attractive with a benefit cost ratio (BCR) of 3.2, but could not reach target water quality standards. To approach the target water quality, both advanced domestic (nutrient removal systems) and industrial wastewater treatment interventions were required, leading to a BCR of 2. We showed that benefits from selling recovered resources represent here an additional driver for improving water quality How to cite this paper:
