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.
