This study examined the factors influencing the willingness to pay for improved household water supply service in Akinyele Local Government, Oyo State. Data were collected from 107 households randomly sampled from the Local Government Area. A dichotomous choice contingent valuation technique was used to elicit households’ willingness to pay for an improved water supply service. The data were analyzed using logit regression technique. The results show that the mean willingness to pay of households for improved water supply service is 0.696. The positive mean willingness to pay implies that the households demand improved water supply service in which the improvement in the water supply service will directly improve their welfare. The results further reveal that the significant factors determining households’ willingness to pay for improved water supply service are number of households’ adults, minutes taken to fetch water, and the amount willing to pay by the households for the proposed improvement in the water supply service. The willingness to pay for water is useful in informing water policy makers for future water supply and services improvement in the Oyo state, Nigeria.

The largest environmental challenge that Nigeria is facing today is water scarcity. Current water use already exceeds renewable supply. Many methods have been suggested to increase the sources of water supply; and one of these alternative sources is rainwater harvesting (RWH). Rainfall harvesting from rural/urban catchments has received little attention in Nigeria. To better understand common practises in the RWH community and motivation for collecting harvested rainwater a socio-demographic survey was conducted in the 11 local government areas of Ibadan city in Nigeria to determine the rate of water consumption and supply from current water sources. The methodology adopted was the mixed method approach, involving a detailed literature review, followed by a questionnaire survey of 1067 household respondents. The data collected through the survey were analysed using SPSS and selected statistical methods such as Chi-square test. The survey was carried out from July-September 2012 and a response rate of 89% (950 households) was recorded. The survey questions focused on the socio-economic characteristics of households and the sources of water supply, catchment materials, rainwater harvesting technology, purpose of RWH, demand and usage of water, effectiveness of management strategy and environmental health. The most commonly reported source of water supply is groundwater with>83.8% of respondents depend on it as their main source of supply, which are vulnerable to drought and pollution while only 6.6% harvest rainwater. 69% of the respondents have corrugated iron sheet while <14% of the respondent’s roof are made of roofing tiles and cement concrete respectively. 54% of those with roofing tiles use the harvested water for drinking, while 43% of those with cement roofs use it for cooking and drinking respectively. A larger proportion (61.2%) of respondents chose prevalence of typhoid fever in the study area; some have a prevalence of diarrhoea (19.4%), while few of respondents’ water sources is free from water-borne diseases (2.3%). This indicates that there is a prevalence of 97.8% of water-borne diseases. Over 77.1% of respondents did not receive water at all from Water Corporation of Oyo State, while few of respondents did receive water supply. This survey provides critical data about current potable and non-potable RWH practices in Nigeria and can serve as guidance for future RWH research. In particular, the inadequacy of water supply in the City should be investigated further as the demand for sustainable RWH system in Nigeria continues to grow.

The spatial and seasonal variations of heavy metals concentrations (Cd, Cu, Ni, Zn, Pb, Co, Mn, Fe) in water and sediments of different sites at the Northern Red Sea coast during the year 2012 were investigated. The results revealed a small range of variation and regional irregularities. Site III (Hurgaha Harbor) recorded the highest metal concentrations in water and sediments except Co during the different seasons. The annual means of metal concentrations in water were 0.14 ± 0.04 - 0.42 ± 0.03, 0.39 ± 0.11 - 4.71 ± 0.87, 0.16 ± 0.04 - 2.15 ± 0.10, 0.94 ± 0.07 - 12.07 ± 2.78, 0.73 ± 0.43 - 5.84 ± 0.74, 0.10 ± 0.02 - 0.42 ± 0.01, 0.06 ± 0.04 - 0.39 ± 0.07 and 8.68 ± 0.80 - 36.53 ± 2.76 µg l-1 for Cd, Cu, Ni, Zn, Pb, Co, Mn and Fe, respectively, while in sediments were 1.73 ± 0.36 - 4.40 ± 1.99, 8.5 ± 0.37 - 111.3 ± 23.89, 16.20 ± 1.39 - 39.00 ± 1.95, 19.23 ± 3.01 - 190.33 ± 13.02, 16.00 ± 0.82 - 80.33 ± 4.19, 10.10 ± 1.68 - 19.23 ± 2.47, 106.00 ± 10.20 - 323.33 ± 46.35 and 4172.00 ± 430.37 - 14222.33 ± 691.02 µg g-1, respectively. According to different standard marine water and sediments quality guidelines, heavy metals concentrations at the most of studied sites appeared within the normal range.
