Co-Author(s): Adenaike, O. A.

This paper provides the basic data for better focusing of intervention efforts for the provision of safe drinking water for household communities. The study surveyed households in 11 communities and obtained information from 330 water consumers in Afikpo North Local Government Area of Ebonyi State, Nigeria. Data was generated on the sources of drinking water, prevalence of waterborne diseases and socio-demographic categories. Water samples from the major sources of drinking water in the study area were taken and analyzed for colonies of microorganisms, coliform organisms and E-coli. The sources of drinking water in the study area are the water boreholes (71.21%) sachet water (9.70%), spring water (8.79%), harvested rainwater (6.67%) and others (3.63%). The prevalence of waterborne disease include typhoid fever (20%), diarrhea (14.55%), dysentery (7.27%) and Hepatitis A (1.52%). The prevalence of typhoid fever and diarrhea was high among consumers of water from boreholes and sachet water, which are the major sources of drinking water. The study found a strong association between age bracket and prevalence of waterborne diseases ((R2 = 0.855, F = 15.720, P < 0.005). The study concludes that safe drinking water interventions in the study area should focus more on improving microbial water quality in terms of water abstraction, treatment and storage. The study recommends that stakeholders who offer safe drinking water interventions supply in Afikpo and Unwana Towns should consider the provision of hardware/technical facilities that are simple to maintain and that guarantee safe water quality in the long run.

Lead Author: Ananti, J. E.
Co-Author(s): Nwosu, N. O.

This Paper on the Modeling and simulation of 58 Bus 330k Nigeria Network is a complete modeling of Nigeria interconnected Power network. Its objective is to determine the structure of Nigeria Power network, to model a power flow on transmission lines and to develop a Simulation Model and the Simulation of 58 Bus Nigeria 330kv Transmission Network. The research material for this research is the 58 buses Nigerian 330-kV Transmission Network which shows that The Nigerian Transmission grid is made up of interconnected network of 6702 km of 330-kV that spans the country nationwide . The system may be divided into three geographical zones-North, SouthEast, and the South-West. The North is connected to the South through the one-triple circuit lines between Jebba and Oshogbo while the West is linked to the East through one transmission line from Oshogbo to Benin and one double line from Ikeja to Benin. The transmission grid is centrally controlled from the National Control centre (NCC) located at Oshogbo in Osun State, while there is a back-up or Supplementary National Control Centre (SNCC) at Shiroro in Niger State. The 58 bus Nigeria 330kV transmission line network was modeled in PSAT 2.1.8. The simulations of Nigeria 330kV was solved using the power flow equations and Newton – Raphson method of load flow solution. Results shows that ordinary line diagram of the 58 Bus network of Nigeria in a line diagram without full interconnections of the network that may not be used for further studies of the Nigeria network. But the simulated network in a PSAT Model for 58 Bus Nigeria 330 kV Network without a device like the flexible alternating current transmission system ( FACTS) Device gave provisions for insertion of devices that may help for future studies like identification of violated voltages on the network, insertion of devices like Static Synchronous Series Compensator, unified Power flow controller, and Static compensator (STATCOM). Therefore it is highly recommended that a Power system Analytical Tool (PSAT) should be used in the modeling of Nigerian Power network that can be use for further studies.
