Tenders are invited for Construction of Borehole Water Supply Infrastructure in Durdur Idp, Burao. 1.1. Description of programme location The Durdur IDP settlement in Burao, Togdheer region, faces significant social and economic challenges, including limited access to income, education, and essential services, which puts children at risk of losing parental care. SOS Childrens Villages implements the TV-Gala Family Strengthening program here, providing household economic support, training in parenting skills, case management, and referrals for health and education in collaboration with local stakeholders. However, access to clean and safe water remains a bottleneck for familys ability to be self-sufficient, as the community is heavily reliant on costly and inconsistent water trucking that leaves no room for other necessary expenses. To address this, SOS Childrens Villages Somaliland drilled a new borehole in Durdur IDP to provide reliable access to safe water, that provides a cheaper alternative and simultaneously helps to improve multiple areas such as health, hygiene, and wellbeing for approximately 1,500 households. In addition, supporting borehole water infrastructure will be developed, including pipeline extensions, construction of elevated water tanks, water kiosks, installation of a solar-powered system, and construction of a guard & generator room and perimeter fence. 2.
