In September 2006, BORDA started the SADC BNS program through co-operation with TED (Technology for Economic Development), a Lesotho-based NGO. In February 2010, a regional office was established in Dar es Salaam, Tanzania. The regional office coordinates the program activities, facilitates a constantly growing BNS network within the SADC region and links up with BNS networks in South and South-East Asia. Further more BORDA co-operates with the Water and Sanitation Association of Zambia (WASAZA), based in Lusaka. The BORDA BNS network develops and delivers the following service packages: Decentralized wastewater and urban sludge management, Community-Based Sanitation (CBS) with integrated wastewater treatment for community and public sanitation center and simplified sewer systems, School-Based Sanitation (SBS), Decentralized solid waste management (DESWAM), Biogas technologies, City Wide Sanitation Planning, Health & hygiene education (HE) and health impact assessment (HIA) and Quality management. All service packages are adapted to the conditions and requirements of the individual country and are supported by an adequate quality management system (QMS).
