Emergency Faecal Sludge Management – Lime Treatment
Description of the emergency context
Bentiu IDP camp located in Unity state, South Sudan hosts a population of 102,811 as of October population count. The camp has been in existence since 2014 as a Protection of civilian Site (PoC) established after the conflict displacement. In March 2021, the PoC transited to and IDP camp. In 2021, Unity state experienced severe flooding and in September 2021, the flood water reached Bentiu with water levels picking significantly around mid-November 2021 to an average water level of 1.2m. The rising water levels forced residents to flee their homes to nearby higher grounds, destroyed livelihoods and infrastructure, disrupted service delivery, and cut-off the supply chain; leaving displaced population overcrowded in temporary sites and to protect human lives form the flood treats dykes were constructed around Bentiu.
Description of the treatment process
IOM with support from MSF established an emergency faecal sludge management plant (FSM) within the IDP camp in order to manage liquid waste in the camp to avert any public health hazard since the access to the oxidation ponds was cut off by the floods. The operation of the emergency FSM plant started from the 13th October 2022 until 22 January 2023.
IOM used lime to treat and ensure pathogen reduction of the influent by raising of the pH levels to high alkaline conditions.
