It is not yet known which of the pre-quake contingency plans remain in place. There is no available electricity supply in the worst effected areas and no piped water. Pipes are damaged and pipe sets not working. An emerging priority now is restoration of drinking water. Failure of the power supply and damage to water sources means available water must be fully tapped and alternative sources identified.
Immediate demand is for the transportation of water to people.
Depending on earthquake damage, existing water points may no longer be accessible and the only source of drinking water is from surface water bodies, which are heavily contaminated by animal carcasses or raw sewage. The risk of gastrointestinal disease is an inevitable consequence if massive water purification measures are not immediately undertaken. To supply potable water to affected communities, including tanker supplies, disinfection, and purification of household drinking water. To accelerate the minor repair and maintenance of existing, damaged, water supply systems. To increase sanitation coverage for the affected communities to ensure the safe disposal of excreta and minimise the risk of disease.
