Item Assessment of Flow Pressure in Selected Zones of Ilorin Township Water Supply(Department of Civil Engineering, University of Ilorin, Nigeria, 2006) Ayanshola, A.M.; Sule, B.F.In our societies today such as Ilorin metropolis, the study area, the objective water supply system has not been attained, thus calling for improvement in pipe distribution system to supply water to various consumers more effectively. In an attempt to improve the service, the Kwara State Government constructed additional service reservoirs at different locations within the metropolis; most of which receive water from Agba dam treatment plant. Pipe network analysis was then carried out based on the demand in the study area. 10 cases were considered using the location of the service reservoirs in relation to the study area and also on the actual production for distribution to the three zones within the study area. The pressure distribution at the nodes was determined for the ten cases. The maximum and the minimum nodal pressures obtained were compared with recommended values for satisfactory performance of a water supply pipe network.Item Domestic Water Consumption Pattern in the Federal Capital Territory, Abuja, Nigeria.(International Association for Modelling and Simulation Technique in Enterprise, Lyon, France, 2013) Ayanshola, A.M.; Sule, B.F.; Salami, A.W.; Okeola, O.G.This paper examined the residential water consumption pattern in the Federal Capital Territory (FCT) Abuja, Nigeria. The parameters considered were volume of water use, population, numbers of toilets and number of rooms in the houses at household level of residential areas. Analysis was carried out on hourly, daily and weekly bases to obtain the trend of water usage. Daily water use has been modelled in order to establish the structural relationship between the variables and household water demand and to reveal the determinants of the variation of water use. The results showed that the average water consumption rate is 251.47 litre/capita/day, which is much more than the minimum value of 120 litre/capita/day recommended by WHO. The test on model results indicated that number of toilets; number of rooms and household population are significant and are positively related to the average daily water demand.Item Evaluation of Supply Variability of Household Water Use in Ilorin Metropolis, North Central Nigeria(Wollega University, Ethiopia, 2015-06-19) Ayanshola, A.M.; Sule, B.F.; Mandal, KItem Evaluation of Willingness to Pay for Reliable and Sustainable household Water Use in Ilorin, Nigeria(African Journals Online, 2013-11-04) Ayanshola, A.M.; Sule, B.F.; Salami, A.W.This study focused on the evaluation of willingness-to-pay (WTP) for sustainable household water use in Ilorin, Nigeria. The study involved assessment of the existing water supply situation particularly considering water use indicators such as demography, adequacy of existing water supply system and WTP for reliable supply. Field work involved the use of structured questionnaire to obtain data on household water use and WTP for a reliable water supply of the sampled houses consisting three land use patterns. Stata/SE 8.0 and Microsoft EXCEL software were employed to evaluate the variables that affect WTP for improved household water use while ccontingency Valuation Method was adopted to evaluate the WTP for reliable and sustainable service delivery. The findings of the study revealed that: approximately 70 % of total sampled households were connected to municipal supply out of which 13 % indicated satisfaction in terms of sufficiency and 87 % used alternative sources to augment water supply; consumers are willing to pay an average sum of N737.22 per month for improved water supply services and; gender, water quality and household income level have significant impact on WTP at 5% level of significance. There is the need to put in place a framework to enhance improvement of system reliability and sustainability.Item Household Water Use Survey Methods: Challenges and Prospects(National Water Resources Capacity Building Network North Central regional Center (NWRCBNet_NC), University of Ilorin, Nigeria, 2010) Ayanshola, A.M.; Sule, B.F.Item Modelling of Residential Water Demand at Household Level in Ilorin Metropolis, Kwara State, Nigeria(Department of Civil Engineering, University of Ilorin, Nigeria, 2010) Ayanshola, A.M.; Sule, B.F.; Salami, A.W.Accurate estimation of water use is one of the challenges facing water supply sector in our society. This is due to lack of adequate and reliable supply and demand data. This paper examined and determined water demand at household level in some randomly selected houses within the city of Ilorin. The study evaluated household water consumption with the aid of structured questionnaire to sample people's opinion in the study area. Regression analysis was used to determine the variables that affect household water consumption. Based on the analysis the average daily consumption was found to be 86.22 lie/d. The study also showed that income, education level, and sex have significant effect on water demand in the sampled households.Item An Optimization Model for a Water Distribution Network Design(Eliva Press, 2020) Ayanshola, A.M.; Sule, B.F.Item An Optimization Model for Sustainable Water Distribution Network Design(Faculty of Engineering, University of Lagos, Nigeria, 2013) Ayanshola, A.M.; Sule, B.F.; Salami, A.W.This study presents a method for optimizing the design of a water distribution network using pipe diameter as a decision variable under the required demand loading and hydraulic conditions. Data was collected from field studies and an optimization model was formulated from the obtained information using pipe diameter as decision variable. Hydraulic conditions were simulated with EPANET 2.0 software while the optimization model was solved using LINGO 13.0 software. The result of the study revealed that an increase in minimum pressure will lead to reduction in the required pipe diameter. Also the predominant pipe sizes in the optimum solution of the model were 100 mm and 150 mm. However, at higher values of minimum pressure, pipes of larger diameters were not required to obtain the optimal solution to the water distribution system. The optimization model developed will be very useful for determination of economical pipe sizes in a water supply system for newly planned layout and for evaluating existing distribution system for upgrading and strengthening
