LITERATURE REVIEW
INTRODUCTION
Water is a natural resource of fundamental importance and supports all forms of life. Water demand already exceeds water supply in many parts of the world, and as world population continues to rise at an unprecedented rate, many more areas are expected to experience this inbalance in the near future (Wikipedia, 2008). It was revealed in the 4th World Water Forum march (2000) that a person living in an urban area uses an average of 250 liters/per day; but individual consumptions varies around the globe.
Nigeria is endowed with abundant natural water resources evident in her substantial yearly rainfall, large surface bodies of water-rivers, streams and lakes, as well as in abundant reservoirs of underground water whose extent and distribution have not been fully assessed. Figures of stream discharges of the flowing surface waters are now available and rainfall, which is perhaps the most important of the country‟s natural water resources, has long records which in some places date from as far back as 1906, (Orjiakor, 1985). The annual mean rainfall distribution ranges from about 4000mm at the coast to practically zero at the northern border and an average annual mean of 1200 mm for the entire country. Over eighty percent of the rains in the country fall within the six wet months (April to September), of each year. A sizeable amount of the rainwater is lost by percolation to underground flows. The bulk of the rain, however, flows as runoff into rivers, streams and lakes. From these surface water bodies and through vegetation some of the rainwater is lost to the atmosphere by evapotranspiration.
WATER RESOURCES OF NIGERIA
Nigeria is well drained with a close network of rivers and streams. Some of these, particularly the smaller ones in the north are seasonal. There are four principal surface water basins in Nigeria.
The Niger Basin which has an area of 584,193km2 within the country, which is 63% of the total area of the country, and covers a large area in central and north-western Nigeria. And the most important rivers in the basin are the Niger and its tributaries Benue, Sokoto and Kaduna.
The Lake Chad Basin in the northeast with an area of 179,282km2 or 20% of the total area of the country is the only internal drainage basin in Nigeria. This is because it does not terminate in the Atlantic Ocean. Important rivers are the Komadougou-Yobe and its tributaries at Hadejia, Jama‟are and Komadougou-Gena.
The South-eastern littoral basins, with the main water courses being the cross and Imo rivers, have an area of 584493km2, which is six percent of the total area of the country, and receive much of their runoff from the Plateau and mountain areas along the Cameroon border.
The south-western littoral basins, with an area of 101,802km2, which is 11% of the total of the country. The rivers originates in the hilly areas to the south and west of the Niger river.
In addition to the surface water, Nigeria has extensive ground water resource, located in eight recognized hydrological areas together with local ground water in shallow alluvial (Fadama) aquifers adjacent to major rivers:
The Sokoto basin zone comprises sedimentary rocks in north – east Nigeria. Yields ranges from below 1.0 to 5.0 litres per second (l/s).
The Chad basin zone comprises sedimentary rocks. It has three aquifers zones: upper, middle and lower. Borehole yields are about 1.2 to 1.6 l/s from the upper unconfined aquifer and 1.5 to 2.1 l/s from the middle aquifer.
The middle Niger basin zone comprises sandstone aquifers yielding between 0.7 and 5.0 l/s and the alluvium in the Niger valley yielding between 7.5 and 37.0 l/s.
The Benue basin zone is the least exploited basin in Nigeria extending from the Cameroon border to the Niger – Benue confluence. The sandstone aquifers in the area yield between 1.0 and 8.0 l/s.

THE STUDY AREA AND METHODOLOGY
THE STUDYAREA
Location
Kwara State is located between latitudes 8o and 10o North of the equator and 3o and 6o East of the Greenwich Meridian (Oyebanji, 2000). The state occupies an area of 36,825km2 of land and shares boundary with Niger state in the North, Kogi and Ekiti in the East, Osun and Oyo in the South and an International boundary with the Republic of Benin in the West. Ilorin Local Government shares boundary with Moro, Ifelodun Local Government.
Sample Size and Sampling Techniques
The population of Ilorin was estimated to be 908,490 (population census 2011). In every 3,634 people one person was chosen. Meanwhile sample size of two hundred and fifty respondents was selected at random from total the population. A simple random sampling technique was adopted in this study in which each element (members) of the population has an equal chance of being included in the desired sample. Therefore the total retrieved questionnaires which samples worked with is two hundred and twenty five persons.
The secondary data on water supply was generated from the state public water board, while data on demand was based on household water consumption lifestyle on cooking, washing, bathing and other domestic uses. This is because there is no rate measuring meters which would have been accurate for determination of water use pattern. Questionnaire method was employed to facilitate the estimation of water use in the study area. The questionnaire method involved designing a set of questions.
The research was designed to cover the following areas in Ilorin central, Gambari, Okelele, Pakata, Okekere, Ajikobi, Akerebiata, Adewole, Zango, Ojaoba and Baboko area.

RESULT AND DISCUSSION
INTRODUCTION
This chapter presents the analysis of data and interpretation of findings based on the research questions.
CHAPTER FIVE
SUMMARY, CONCLUSION AND RECOMMENDATIONS
SUMMARY OF FINDINGS
Findings from the study indicate that demand for domestic water varies in terms of household size which shows that the number of people found in a household determines the quantity of water needed for domestic purpose.
The study also shows that females are more involved in collecting water as compared with male counterpart. This findings therefore is in line with the studies of Barkingham (2000) which reported that even though the water crisis is observed as a general problem, women bear the greatest burden because of their social gendered roles, which involve looking for and collecting water for households. The study equally affirmed that water demand and allocation in the household has got a direct link with accessibility of the water supply sources.
The study also reveals that the time spent in collecting water by household is a constraint to their socioeconomic activities, since the household members spend a better part of their time collecting water. This finding is also in line with WHO, (2003) who reported that in Anona and Rakai district of Uganda, young men and women spend most of their time and resources in search of water, which in turn influence the productive time and income generation.
CONCLUSION
A number of studies have been carried out on water resources such as impact of water shortage and depletion on the productive time of women in Ilorin metropolis Ijaya (2000) and distribution of water and the role of public agencies in Ilorin. Adedayo and Ifabiyi (1999). This study however analyzed the Domestic Water Demand and Supply in Ilorin Metropolis, Kwara State with emphasis on Ilorin Central.
The study therefore, found that the study area depends mostly on pipe borne water. The percentage of respondents that source water through tap is higher that other water sources. The study also found that bursting of pipe had been the strongest factor influencing water demand in the study area base on the respondent view. While inadequate supply of electricity is the strongest factor hindering the supply of water as stated by staff of Water Board.
The study further found that, there exist very high positive linear relationship between the household water demand and water supplied by the Kwara State Water Board. From the study, pipe borne water supply in the study area is inadequate to meet the demand of households. In view of these therefore, there is a need for improvement in the quantity of water supply in Ilorin metropolis.
RECOMMENDATIONS
Based on the findings, the following recommendations were made:
- The water board management should be carrying out constant repair, that is reparing of busted pipes around the
- There should be constant monitoring of pipe line so as to be able to repair damaged pipes, this could be achieved by going round to check the water
- The government should endeavor to come to water board aid by proper funding so as to purchase the material needed. e special allocation of fund should be make available to the water board so as to improve theirservice.
- The water board should change their attitude of bias in distributing water to households not to favour Government Residential Areas at the expense of the masses in the town.
- There should be concerted efforts by water corporation and household to avoid water wastage, this can be achieved by public enlightenment through the mass media and the customers also should endeavor to report cases that can cause failure in water
- There should be an extension of water pipe to cover more areas especially in the rural areas and rusted pipes in the urban centre should also be replace with new
- The consumers should endeavour to pay their water bill regularly so as to improve the water supply.
