Widespread groundwater arsenic contamination in south, south-western and north-eastern regions and high salinity in the south-western coastal region are the two major challenges for drinking water supply in Bangladesh. In this study, we assessed various water supply technologies used for mitigating arsenic and salinity in Laksam of Cumilla and Assasuni of Satkhira district. Water samples were analyzed for Arsenic, Iron, Chloride (indicator for salinity) and FC from different water extraction systems (shallow, deep and Tara tubewells), groundwater arsenic treatment units (SIDKO and READ-F), rainwater harvesting systems (RWH), pond sand filters (PSF), and managed aquifer recharge units. Most shallow tubewells, both in Laksam and Assasuni, have been found to produce arsenic contaminated water. But water from deep and Tara tubewells have been found arsenic-free, though high concentration of iron was observed in the wells in Laksam. Rainwater harvesting systems, PSF and MAR units in Assasuni have been found to provide water free from the common chemical contaminants but suffer from high bacterial contamination. Deep tubewell appear to be the most preferred option where a suitable aquifer is available. The community-scale groundwater treatment systems would require strong operation and maintenance support from the service providers to be successful. Environ.

Several programs have been undertaken during the last few years to install rooftop rainwater harvesting systems as an alternative drinking water supply source both in the coastal and arsenic affected areas in Bangladesh. In this study, quality of the harvested rainwater used for drinking water supply was assessed. A total of 308 harvested rainwater samples were collected from the different storage reservoirs located both in coastal and arsenic affected areas and analysed for various physical, chemical and microbial indicators. Most of the physical and chemical water quality parameters were well below the Bangladesh Drinking Water Standard and WHO guideline values. However, the harvested rainwater was found microbiologically contaminated to some extent and the water is not suitable for consumption without treatment. For safe and sustainable rainwater harvesting, WHO guideline and water safely plan (WSP) can be adopted in Bangladesh.

Purpose In March 2015 Vanuatu experienced Tropical Cyclone (TC) Pam, a category 5 cyclone with estimated wind speeds of 250 kph and one of the worst disasters in Vanuatu’s history. Prior to the cyclone, one-third of water in Vanuatu was collected by means of rainwater harvesting systems; around one quarter of these systems were damaged due to the cyclone and no longer functional. The purpose of this paper is to investigate social and organisational complexities in the resilience of water systems in Vanuatu following TC Pam, focussing on rural areas. Design/methodology/approach The resilience of water supply in rural responses to TC Pam was examined using the three following approaches: review of existing documents, a case study of a village and interviews with specialist local and international non-governmental organisation staff working in Vanuatu. Findings People’s reaction to the cyclone and its consequences at the village or community level in Vanuatu was impressive. The capacity of the locals, their involvement in the community and the low level of violence and high level of trust within society contributed to a quicker water supply restoration than expected. Despite severe shortages of water in some areas due to physical vulnerability of the system, the communities dealt with the issue calmly and the country did not experience any chaos due to water shortages. Originality/value The research results provide a benchmark for planners and decision makers in the South Pacific based on the social, organisational and technical dimensions of rural areas in Vanuatu that can be generalised to other countries in the region. This study also recommends potential tools to improve assessment of the role of social capital in fostering water supply resilience.

Five different water resource management scenarios are examined on eight dry islands of the Aegean Sea in Greece, pitting the current practice of water hauling via ship against alternative water supply schemes in delivering a sustainable solution for meeting water demand. The first scenario employs current water supply practices along with the operation of domestic rainwater harvesting systems. Desalinated water, provided through the operation of wind-powered desalination plants, is considered the main source of potable water in the rest of scenarios. Wind-powered desalination may be combined with rainwater harvesting as a supplementary source of water and/or seawater pumping and an additional source of energy that is supplied to the system. All different alternatives are evaluated for a 30-year lifespan, and an optimal solution is proposed for each island, based on a life cycle cost (LCC) analysis. The performance of this solution is then assessed under six climate change (CC) scenarios in terms of the rate of on-grid versus off-grid renewable energy that is required in order to achieve a certain reliability level. Overall, the examined scenarios show a decreasing performance in terms of reliability under CC for the eight islands.

Rainwater harvesting systems are often used as both an alternative water source and a stormwater management tool. Many studies have focused on the water-saving potential of these systems, but research into aspects that impact stormwater retention—such as demand patterns and climate change—is lacking. This paper investigates the short-term impact of demand on both water supply and stormwater management and examines future and potential performance over a longer time scale using climate change projections. To achieve this, data was collected from domestic rainwater harvesting systems in Broadhempston, UK, and used to create a yield-after-spillage model. The validation process showed that using constant demand as opposed to monitored data had little impact on accuracy. With regards to stormwater management, it was found that monitored households did not use all the non-potable available water, and that increasing their demand for this was the most effective way of increasing retention capacity based on the modelling study completed. Installing passive or active runoff control did not markedly improve performance. Passive systems reduced the outflow to greenfield runoff for the longest time, whereas active systems increased the outflow to a level substantially above roof runoff in the 30 largest events.

Rainwater harvesting is a potential option of water supply to the coastal and arsenic affected rural communities in Bangladesh and during the last few years, several projects were undertaken to promote and install various types of rainwater harvesting systems by government organizations and NGOs mainly for drinking and cooking water supply. A study was undertaken to assess the currently practiced rainwater harvesting systems located in the south west coastal and arsenic affected areas in the country. A total of 1,000 rainwater-harvesting systems were investigated using structured questionnaires; among them 14.8% were community based and 85.2% were household rainwater harvesting systems. The results of this assessment are presented in this paper. Availability of the harvested rainwater, operation, storage and maintenance of community based rainwater harvesting and ensuring water quality to meet the drinking water standard are the important issues that must be addressed properly. A protocol for the operation and maintenance according to WHO guideline can be adopted for the safe and sustainable rainwater harvesting in the country.

Rooftop rainwater harvesting has received an increased attention as a potential alternative water supply source both in the coastal and arsenic affected rural areas in Bangladesh. Several programs in installing rainwater harvesting systems have been implemented to mitigate the drinking water problem in the coastal and arsenic affected areas in the country. This study was conducted with a view to assess sanitary integrity, microbial contamination and the associated health risk of the currently practiced rooftop rainwater harvesting mainly used for drinking water supply. Sanitary inspection of the rainwater harvesting systems and an extensive sampling of harvested rainwater from the storage reservoirs and laboratory analysis were conducted. The study findings reveal that harvested rainwater was found to microbiologically contaminated to some extend. The disease burden estimated using QHRA model showed a significant microbial health burden associated with drinking untreated rainwater and both viral and bacterial pathogens dominate the microbial disease burden. In context of arsenic mitigation, rainwater harvesting reduces the health risk from arsenic; however it may increase the microbial disease burden much higher than the level of arsenic health risk at 50 μg/L of Bangladesh standard. Microbial risk needs proper attention through the implementation of a water safety plan for safe and sustainable rainwater harvesting in Bangladesh.
