The construction of sufficient latrines for displaced people in rocky, high water-table areas can be a problem. This article describes how shallow trench latrines were trialled after the Pakistan floods, and these proved to be easy to construct and well accepted.
Water, sanitation and hygiene (WASH) response in urban contexts has been identified by the Global WASH Learning Project as a priority for technical learning in the sector. The increased numbers of earthquakes and cyclones have brought us all closer to urban environments, yet it is recognised that many agencies lack adequate skills to address the complex challenges involved. Urban flooding is one type of emergency that requires a WASH response. Material in the paper is based both on a rapid review of literature, and on outputs from a learning workshop held in Haiti in March 2009.
Effect of well cleaning and pumping on groundwater quality of a tsunami-affected coastal aquifer in eastern Sri Lanka
Changes in water quality of a sand aquifer on the east coast of Sri Lanka due to the 26 December 2004 tsunami and subsequent remediation attempt by pumping were investigated. Two transects, disturbed (where pumping of groundwater took place) and undisturbed (where no pumping occurred), were monitored. In the undisturbed area, the average electrical conductivity (EC) in the wells affected by the tsunami showed a decrease from 3000 to 1200 μS/cm after the first full rainy season following the disaster; however, in the disturbed area the average EC stabilized around 1500 μS/cm.
Potable water issues during disaster response and recovery: Lessons learned from recent coastal disasters
An immediate need and vital resource, potable water becomes critical in the aftermath of a disaster; affected communities cannot recover and return to normal conditions until water infrastructure is restored. This paper explores the public health impacts associated with the lack of water supply in the immediate aftermath of a coastal disaster, the effects of coastal disasters on various water supply infrastructures, and strategies and solutions for supplying potable water to victims after a major coastal disaster.
The Application of Ecological Sanitation for Excreta Disposal in Disaster Relief Open Primary tabs configuration options Primary tabs
When responding to an emergency situation, ensuring safe excreta disposal is an urgent priority in the disaster relief effort. Depending on the environment, not all methods of sanitation are appropriate, so methods such as ecological sanitation (Ecosan) must be employed. Ecosan are sanitation methods and technologies that promote the safe resuse that allow additional benefits such as nutrient recovery, reforestation, and help begin post-disaster recovery and transition to sustainable develoment.
Adherence to Point-of-Use Water Treatment over Short-Term Implementation: Parallel Crossover Trials of Flocculation Disinfection Sachets in Pakistan and Zambia
The health benefits of point-of-use (POU) water treatment can only be realized through high adherence: correct, consistent, and sustained use. We conducted parallel randomized, longitudinal crossover trials measuring short-term adherence to two single-use flocculant–disinfectant sachets in Pakistan and Zambia. In both trials, adherence declined sharply for both products over the eight week surveillance periods, with overall lower adherence to both products in Zambia. There was no significant difference in adherence between the two products.
