This report contains the inventory of sewerage technology in the urban cities of the country with their associated problems and recommendations on how to adopt a local technology that could meet the need of our society. Preliminary activities involved literature search to find out what has been done in this regard in the past. This was followed by training of the enumerators. Pilot study was undertaken during the training using the city of Ibadan as the focal city in the southwest geopolitical zone. This was done to ensure that when our enumerators are sent to the field, they will be able to replicate what they have done during the pilot study. Then the country was divided into six according to the geo-political zones. The study approach involved the use of survey instruments (questionnaires) to gather primary data relating to sewerage systems in Nigeria. The questionnaires were in two Parts, with the first part addressing general information while the second part was an interview guide used for collecting data from selected stakeholders. Facilities were surveyed in communities where they exist and determination of their coordinates was carried out by members of the project team with the aid of GPS units. During the field survey, photographs were taken and compiled. Data collected were classified, organised and analysed manually. Findings were represented graphically and it constitutes the bulk of this report.
