Predictive Logistic Modelling for Sustainable Portable Water Supply in Ghana

Christiana C. Nyarko, Peter K. Nyarko

Abstract: One of the primary goals of World Health Organization (WHO) and its member states is that all people, whatever their stage of development and their social and economic conditions should have the right to access adequate supply of safe drinking water. Water of course is essential for the survival of humans, animals and plants. A signi?cant proportion of the world?s population use potable water for drinking, cooking, personal and home hygiene. However, the quality and the quantity of fresh water supply is deteriorating globally as a result of rapid urbanization, population growth and industrialization. This paper seeks to focus on how to predict and supply portable water to every household in Ghana by 2050taking into account the water source at Weija and Bonsa in Greater Accra Region and Western Region respectively. A Mathematical model was formulated to estimate the required quantity of water needed to be produced based on the population density. In order to sustain its production, the developed model was used to predict the population of Ghana for the next 30 years using Logistic Growth Model. Results show that,in2010, when the actual population of Ghana was 25, 574, 719 million, the predicted population was 19,918,781 with a demand for water as 3452587065 and 2,689,035,435litres respectively.Thus, in 2030 it is predicted that the population of Ghana is expected to increase to 27,589,274 million with a domestic demand of 3,724,551,990 litres which indicates that as the population growth increases the demand for portable water increases exponentially hence affecting the quality of portable water to be supplied due to treatment cost. Thus, it is suggested that Government as well as stakeholders should continue to intensify the educational campaign against illegal mining activities along the water bodies in Ghana to save lives and minimise cost and constant supply of portable water.
