ANALYSIS OF THE FACTORS AFFECTING WATER SUPPLY AND DISTRIBUTION IN OLOJE ESTATE ILORIN, KWARA STATE.
Abstract
A major challenge facing many countries of the world is how
to balance the rate of demand and supply of safe water for the domestic
consumption of their citizens. It has been noted that many occupants of the
residential estate in Oloje have problems of water supply and distribution to
their building. This research was carried out to assess the problems associated
with the water supply and its distribution in Oloje Estate and recommending
ways of improving the system. The methodology involve the administration of
well-structured questionnaires, oral interview with KWWC officials, laboratory
testing of the physiochemical qualities of water from each source and review of
related literature. Results show that only about 26% of the total residents of
this estate get their water supply from the Utility Board (KWWC). Consequently,
most of the residents rely on alternative sources which are usually untreated.
Findings also revealed that the Borehole water source is the most preferred
water source to the residents of Oloje Estate with 41.75% and only 5.11% of the
residents travel more than 1000m to their alternative sources of water supply.
The research also shows that the level of adequacy of water supply to the
Estate by the Kwara State Water Corporation is low and the major impediment to
this short fall in supply is Lack of Governmental Intervention. The inadequate
supply of treated water is however continuously causing problem of poor
sanitation and bad health, leading to shorter life span as well as social and
economic backwardness of the area.
CHAPTER ONE
1.0 INTRODUCTION
1.1 Background of the
Study
The term “built environment” refers to the human made
surrounding that provides the setting for human activities ranging in scale
from buildings and parks or green space to neighborhood and metropolis or areas
that often include their supporting infrastructure such as water supply, or
energy networks.
All people have the right to have access to water supply in
quantities and of good quality equal to their basic needs irrespective of their
stage of development and their social and economic conditions (Mar del Plata
Water Conference, 1977). Water is the most important of all public utilities.
It is second to oxygen in the sustenance of human lives. Anything that disturbs
the availability and supply of water therefore tends to disturb the survival of
humanity. However, when it is inadequate in either quantity or quality, it can
be a limiting factor in poverty alleviation and economic recovery resulting in
poor health and low productivity, food insecurity and constrained economic
development. Poverty in Africa has been the major factor of inadequacy in
access to water and sanitation (Gbadegesin, 2007).
Water is fundamental to life and health. The significance of
water to man never be over emphasized. It is the most important beneficiary
factor to man’s sustenance, apart from shelter, food and clothing (Ajadi,
1996). It is the basic ingredient which life as a whole depends on. It serves
as the major source of survival to plants, animal and human being, without
water existence of life on earth is impossible (Asthana and Asthana, 2001). To
lead a healthy life in human society, the uses of water cannot be over emphasized.
It is a prerequisite to the realization of all other human rights. Water is
needed to sustain life and it has always been a subject of great interest to
man since it forms the basis for human survival as a function of its important
usage for both domestic and industrial purposes. It is a foundation for human
prosperity because adequate and high quality water supplies provide a basis for
the growth and development of human, social, economic, cultural and political
systems (Young, 2006). From the beginning of human civilization or even the
origin of man to be precise, man is always found to settle where he has easy
access to water like lakes, rivers, streams and other bodies of water. Indeed,
anywhere you see man; there must be provision for water even if it is at its
lowest quantity.
According to the World Health Organization (WHO, 2004), the
total domestic water demand by man for domestic activities is estimated as 250
litres per capita per day. For this reason, the possibility of life (or man’s)
existing in any particular place depends on the presence or accessibility to
water. It was observed by Oyebande (1977), that “the priority accorded domestic
water supply by colonial administration had not been sustained by
post-independence governments of the country. It was also noted that between
1946 and 1960, the average percentage of the total government expenditure on
water was 11.4% whereas between 1962 and 1975, it decreased to 4.5%”. The total
domestic water needs in homes with piped water and inside sanitation is at
least 115 liters per head per day. The actual amount used by any individual may
be greater or lesser depending on the ease and convenience of supply (Ayoade
and Oyebande, 1983). Over the years, as human race grow in population the need
for more building arises thereby increasing the demand for sufficient water
supply and distribution within our built environment. All over the world,
millions of miles of water distribution pipeline provide drinking water to
individuals and industries. WHO and UNICEF Joint Monitoring Program currently
estimates that 1.1 billion people (17% of the global population) lack access to
water resources, where access is defined as the availability of at least 20
liters of water per person per day from an improved water source within a
distance of 1 km (Bates et al., 2008). The rapidly growing world population is
contributing to the deterioration of the available fresh water quality and is
creating significant challenges for water managers, industries and fishes and
wild life agencies.
The resulting polluted water contains protozoa, viruses,
bacteria and intestinal parasites which cause water borne diseases (Thomas,
2005). The worldwide water issue made the United Nations general assembly in
December 2003 to proclaim year 2005 to 2015 as the international decade for
action “water for life” which was launched on the 22nd March 2005 by
the then United Nation’s Secretary General Kofi Anan (UN, 2003). This has woken
the world awareness to the pressing water issue. Water distribution systems are
large network of storage tanks, valves, pumps and pipes that transport finished
water to consumers. Finished water here means water that has been treated and
ready for delivery. Water is an important geomorphic agent playing a
significant role in weathering the most important energy regulator in the heat
budget of the earth (Ayoade, 1988). The value of water, therefore, is
determined by two elements, supply-the cost of providing the resource in a
certain quality, quantity, and location which varies in different parts of the
country and demand-the utility to humans and their willingness to pay for that
utility (Cech, 2005).
Although Nigeria is known to be endowed with abundant water
resources, the availability of potable water is a problem in many parts of the
country (Onokerhoraye, 1995). The Nigerian Government has long considered the
provision of water supply services to be the domain of the Federal, State and
Local Governments. However, the public sector has not been successful in
meeting more than a small portion of the demand for water of residential and
commercial users. Services are in critically short supply (FRN, 2000). Since
1999, a huge amount of public funds have been spent on provision and management
of water. However, there is still no potable water and many lack access to
adequate sanitation. Government insists it cannot handle water supply all by
itself for lack of funds, and have ceded its statutory role to shylock water producers,
who do not know or care about safe water standards (Oghifo, 2008). Many
households, often the poorest, end up purchasing water from private vendors
much more expensively than from the public supply. Water supply services, where
they exist, are unreliable and of low quality and are not sustainable because
of difficulties in management, operation and pricing, and failure to recover
costs. Many water supply systems show extensive deterioration and poor
utilization of existing capacities, due to under-maintenance and lack of funds
for operation (FRN, 2000).
1.2 Need for the Study
In Nigeria today, even though it is blessed with abundant
water resource estimated as 22.6 million m3 surface water and, about
40 million m3 underground water, it is still faced with the problem
of acute shortage of water supply (FMWR, 2006). A major challenge facing many
developing countries is how to supply safe domestic water to their citizens.
The demand for water is rising at an exponential rate due to increasing population.
Water demand has already exceeded supply in many countries of the world, and as
the human population continues to increase geometrically, many more areas are
expected to experience this imbalance in the near future (Wikipedia, 2013). The
number of people who rely on the earth’s limited freshwater reserves is
increasing every day. In fact, a scarcity of clean, fresh water is one of the
world’s most pressing environmental problems (Arms, 2008). The water supply
problem is one of balancing supply and demand, availability of water resource,
geographically and temporally, its quality, rates of replenishment or depletion
as well as demands from end users is major determining factors in any water
management strategy.
At the 2002 World Summit on Sustainable Development in
Johannesburg, South Africa, great concern was expressed about the 1.1 billion
people in the world who do not have access to safe drinking water and the 2.4
billion who live without proper sanitation (Cech, 2005). The resulting human
toll is roughly 3.3 billion cases of illness and 2 million deaths per year.
Moreover, even as the world’s population grows, the limited easily accessible
freshwater resources in rivers, lakes and shallow groundwater aquifers are
dwindling as a result of over-exploitation and water quality degradation (IAEA,
2004).
Many factors are perceived to be responsible for the
inadequate and inequitable water distribution of improved water supply in
Nigeria. Some of the factors include lack of basic planning data, flood and erosion,
manpower shortage and corruption. Human welfare and economic development
generally depend on the use of water. Water as a very vital resource is not in
short in Nigeria and Ilorin in particular, but regulating its availability and
ensuring even distributions is in fact a serious problem. (Sule, 2000).
However, the quantity of portable water available to the
inhabitants has received cries of inadequacies. Two extreme views have been
often expressed regarding availability of water to man. Some believe that man
is in his critical period in water consumption, and that demand is already
overtaking supply. The other view is that water is sufficiently available for
all the time everywhere worldwide. Both views may be acceptable in terms of
water resources availability across the geographical space (Ajadi, 2010). In
Nigeria, water resources management and utilization is crucial to the country’s
efforts to reduce poverty, grow the economy, ensure food security and maintain
the ecological systems. Nevertheless, the issue of water resources management
in the country focuses mainly on water supply and it receives only minimal
attention by government. Water is the most basic resource that forms the
largest part of essentially all living organism. It is more feasible to sustain
human lives longer without food than without water (Ayoade, 1975, 1988; NEST,
1991).
The UN predicts that by 2025, two-thirds of the world
population will experience water scarcities, with severe lack of water
blighting the lives and livelihoods of 1.8 billion. According to the UN World
Water Assessment Program, by 2050, 7 billion people in 60 countries may have to
cope with water scarcity (Chenoweth, 2008). According to NPC (1994), it was
noted that between 1992 and 1996, the total water supply for industrial,
agricultural and domestic used increased at a rate of about 1.0% whereas
population growth rate was at 2.81%. An essential part of all water supply
system is the distribution system. The water has to get to the consumer through
the network of pipelines with a minimum specified residual pressure at
sufficient quantity without degrading its quality from the sources or
purification plants. Among other components, this supply system also includes
hydraulic elements such as pumping stations and storage reservoirs. An
individual distribution pipe network can have many solutions for a
predetermined set of consumptions and pressure head valves, depending on
pumping station, location of elevated storage reservoirs and even the
topography of the area under consideration.
When human do not have access to portable water, they do not
only suffer physically and emotionally but also socio-economically. This can be
the cause of environmental degradation (UNDP, 2006). As the human population
increases geometrically, the means of achieving water supply and distribution
to the populace only increases arithmetically which is a shortfall in supply as
the demand for this amenity has implied.
It has been noted that many occupants of some residential
estates in Oloje, have problems of water distribution in their buildings. The
only reliable source of portable water supply to this neighborhood is the
mechanical bore-holes (hand pump) that are located at some strategic positions
within the estate. Other sources of portable water supply for domestic use in
this estate is the well and water collected from the rain. Another water source
here is water pumped into over-head reservoir by electrical pumps in some
houses with supply pipes outsides the fences. The problem here is to find out
what factors are responsible for the poor performance of water supply. A close
observation of this estate has shown that many houses here have no running
water in their homes. The inability to obtain adequate water and water
facilities to match the growing population in Ilorin has resulted into a social
and economic problem in the area. Water is the key to developmental process of
any nation, as a lack of steady water supply hinders to some extend the influx
of entrepreneurs in establishing activities especially those that are water
dependent (Yusuf et al, 2009).
Kwara State Water Corporation (KWWC), Ilorin, whose
responsibility is to pump and distribute sufficient clean water to the
residents in the study area, is seriously constrained due to its inability to
meet the rising demand of domestic potable water. Water consumption and use has
however been greatly hampered by the increasing population brought about by the
influx of people into the study area (Abaje, et al., 2009).
