Sanitation Safety Planning in Hanoi helps identify and manage health risks to workers, farmers and consumers from reuse of wastewater

摘要

Sanitation Safety Plannings (SSPs) are currently under a piloting phase by World Health Organisation (WHO). SSPs supplement and act as practical application guidance the four volumes of the 2006 WHO Guidelines for the Safe Use of Wastewater, Excreta and Greywater. Two pilot sites were selected in Hanoi, Vietnam to test WHO’s upcoming Sanitation Safety Planning manual: (1) large scale agriculture on the outskirts of Hanoi which uses untreated sewage; and (2) an organic composting site which uses effluent from a purpose built on-site sewage treatment plant for moisture control of the compost. This paper presents a summary of how SSPs helped identify and manage health risks to workers, farmers and consumers of produce from reuse of wastewater. Simple risk-based prioritised low cost improvement plans are summarised.
