3.2.1 Population
Population is the total collection of elements
about which one would wish to make some inferences (Lapin, 1990). It is
composed of the entire set of objects, events or people that can be
studied (Rea and Parker, 2005). In research, however, the interest is in
the working or study population. The working population is that part of
the general population that possesses the characteristics that the
research aims to study, that is, fulfills the requirements of the
research (Scheaffer et al., 2001).
3.3 DATA COLLECTION PROCEDURES
3.3.1 Data collection instruments
Gall
(1996) highly recommended questionnaires as the most convenient and
suitable instruments for both survey and statistical research. Fowler
(1993) explains that vast majority of survey samples involve very small
fractions of populations and small increments in the fraction of the
population included in the sample will have no effect on the ability of
the researcher to generalize from a sample to a population. Therefore
questionnaires and observations were used as data collection instruments
in this research project.
3.3.2 Primary data
Questionnaires
were used to collect primary data. They were designed in two forms; one
involving response by statutory bodies and engineering consultants in
charge of highway construction and maintenance of the drainage, canal
and culvert systems and the other involving response from people living
in the vicinity of the area and road users
(a) Questionnaire type 1 :
Type
one questionnaire was structured and filled by government bodies in
charge of construction and maintenance of drainage systems in Ilorin
west local government area. The key objective of this questionnaire is
to know the responsibilities, and challenges experienced by the bodies
mandated to construct and maintain drainage system of the area. In
addition, it sought to understand the role of the consultant in the
drainage system provision in Ilorin west local government and the
challenges it experienced in design the drainage, canal and culvert
through questionnaire type 1.
(b) Questionnaire type 2:
This
type of questionnaire was structured and filled by road users and the
people who live at Agbo-Oba, Oja-Tuntun and Sawmill in Ilorin west local
government. The road users referred here includes people who travel
through that road frequently, both the public service transport
providers and those using private vehicles and pedestrians. It was
intended to know how blocked drainage, canal and culvert have affected
the lives of the people residing in the area and how activities have
changed because of blocked drainage.
(C) Observation:
Observation
was carried out to ascertain recurrent conditions on the drainage
system in Agbo-Oba, Oja-Tuntun and Sawmill road in comparison with the
acceptable standards and causes of the drainage blockage.
(c) Photography
According
to Kothari (2004), photography is an indirect way of data collection.
It was majorly used to capture the current status of the blocked
drainage system. It was meant to give a visual understanding of the
research topic to the readers of this research project.

ABSRACT - [ Total Page(s): 1 ]ABSTRACTDrainage is an essential component of road construction. In most designs of the road, the first thing to be put in place is drainage system. The presence of blockage in drainage system tends to reduce the carriage capacity of drainage and thereby affect life span of the road. The research employed a research survey in order to obtain the information that would describe the causes of blocked drainage, canal and culvert in Ilorin-west local government road and its effect on the surrounding ...

At the census of November 1991, Nigeria had 88, 514,501 with an inhabitants and a population density of 95.8 per 59 km. The average annual growth rate between 1963 and 1991 is 1.7% (Baiye E; 1991). According to 2006 census figure, Nigeria had a population of 140 million people. The major hazard experienced in Nigeria includes flooding, erosion, deforestation, land degradation and climatic drought ... Continue reading---

CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVE5.0 CONCLUSION AND RECOMMENDATION5.1 CONCLUSIONThe
level of awareness of waste collection services and waste management
regulations were relatively low in Abgo-oba, Oja-tuntun and Sawmil, the
percentage of those who use indiscriminate solid waste disposal methods
like open dumping, open burning and dumping in drainages, canal and
culvert were higher. Educational status, age, gender, cost of waste
collection services and the location of resident among others ... Continue reading---
