Access to improved sanitation services has been observed as one of the integral development strategies to reach the country’s medium and long-term vision of the country. Inadequate sanitation services are detrimental to public health as well as environment. Interestingly, access to sanitation facilities is the key solution to end those issues and another way to protect the environment. It is also an indicator to end poverty and gearing up the national development of the country. The Government of Rwanda has set target to reach un100 Percent universal access to basic sanitation services by 2024 as highlighted in the National Strategy for Transformation (NST) as well as Water and sanitation sector strategic plan 2018-2014.However, the sanitation sub-sector recognizes gaps on appropriate wastewater treatment technologies and faecal sludge management for the collective sanitation facilities. It is in this framework that the Ministry of Infrastructure wishes to put in place a study on the appropriate semi-centralised wastewater treatment technologies and management of faecal sludge for different registered users that might be applied in the City of Kigali and other peri-urban Cities.HICE Consult has therefore been hired to assist the Ministry of Infrastructure to conduct a study on the appropriate decentralized, semi-centralized, wastewater technologies and faecal sludge management in Rwanda. The overall objective of the study is to unveil the appropriate semi-centralized, decentralized, wastewater technologies and faecal sludge management that can be referred on in future by any private operator, developer, or contractor in developing sanitation facilities in Rwanda.
