Minimum Air Gap between Drinking Water Outlet and Surface of Sewage

To prevent the contaminated water from flowing back into the potable water supply, Particle Image Velocimetry (PIV) was employed to measure the variation of flow field and study the relation between the minimum air gap h and the water outlet diameter d concretely. The theoretical analysis and the experimental results show that the h/d is not vary linearly as required in ‘Code for Design of Building Water Supply and Sewerage’ but exponentially.

Potable Water Supply

A fatal nosocomial infection withLegionella pneumophilaserogroup 5 occurred in a patient with leukemia. Isolates recovered from both the potable water supply and the patient showed an identical genomic profile. With no other exposure identified, the water from the washbasin was evidently the source of infection.

Potable Water Supply

Se realizó un análisis comparativo sobre el acceso a los servicios de agua potable entre Panamá y Costa Rica, además de su relación con los indicadores de salud pública y desarrollo, con el propósito de identificar las fortalezas y debilidades que permitan definir metas a mediano y largo plazo. Para el año 2016, la República de Panamá alcanzó una cobertura con agua para consumo humano por cañería de 94,6%, de la cual se estima que el 74,6% fue de calidad potable, específicamente en el área urbana; sin embargo, se desconoce la calidad del agua suministrada por los 5.619 acueductos rurales, debido a que en estos no se aplica el Reglamento Técnico DGNTI-COPANIT 23-395-99. En el caso de Costa Rica y para el mismo periodo, se estima que el 97,6% de los 4.889.762 habitantes fueron abastecidos con agua por cañería, y el 91,8% recibió agua de calidad potable, distribuida en 98% en el área urbana y 78,8% en la rural. Los indicadores básicos de salud y desarrollo son mejores en Costa Rica, lo cual es concordante con la mayor cobertura de agua potable. En ambos países la rectoría es débil y fraccionada; en razón de esto, existen propuestas de políticas nacionales en agua potable, que buscan alcanzar la universalización del suministro de agua potable para el año 2030. Se propone elaborar políticas nacionales del subsector de agua potable, con sus respectivos planes de acción y modelos de evaluación y seguimiento, con el propósito de alcanzar la universalización de los servicios de agua potable en Panamá y Costa Rica en el año 2030.

Water Scarce

This study incorporates a detail exploration of drinking water scarcity in the south-western coastal area of Bangladesh. The objectives were to recognize the constraints of potable water supply in the coastal area and to identify the water-scarce area of a coastal community of Bangladesh. Both primary and secondary data have been used to carry out the study. A total of 349 households were selected by using appropriate statistical procedure. ArcGIS has been used for pertinent mapping and calculating the served and unserved (inadequate supply) area of the nearest community water source e.g. pond sand filters or tube-wells. This study found that the root causes i.e. saline water intrusion, reduction of upstream flow, sea level rise, disasters, polder, arsenic contamination, shrimp cultivation in brackish water, excessive use of underground water and lack of appropriate aquifer were highly influential for the disturbance of potable water supply in the coastal area. In addition, it has been showed that about two-third of the settlement areas as well as households fell into the water scarce zone. J. Environ. Sci. & Natural Resources, 11(1-2): 17-25 2018
