This report is produced, in partnership with UNHCR and upon the request of the WASH sector working group, based on information collected by REACH teams in Northern Iraq through field assessments. The aim of the report is to share REACH’s understanding, as of September 22nd, of humanitarian challenges with regards to WASH related themes across the camps due to the new influx of Syrian refugees in Northern Iraq since August 15th. This WASH Baseline Assessment Report details findings of assessments conducted by REACH between the 15th and 22nd of September in the four Erbil sites (Basirma, Baharaka, Kawergosk, and Quashtapa), the one Sulemanya site (Arbat), and the four newly established Ninewa sites (Bardarash, Akre, Qasarok, and Bekhme) where newly-arrived refugees have been settled. This report complements REACH’s previous Situation Report of September 12th, focusing specifically on the WASH sector in order to provide a baseline overview on themes such as water access, WASH facilities and sanitation, thereby shedding more light on WASH needs in the camps and gaps in current service provision.
