Análise de custo de dessalinização de água em comunidades rurais cearenses

Abstract

The aim is identify the financing feasibility assessment of five Desalinization Systems by Reverse Osmosis (RO) that are used to provide potable water for human consumption in rural communities in the State of Ceará. This study was conducted in the State of Ceará. The data was gathered from primary source by questionnaire application and secondary to municipality and state governmental agencies. The methods applied were the cost and investment analysis taking into account the financing approach. It is concluded that due to the absence of any good management practices it results in financing negative return for some desalinization equipment when they were evaluated according the effective consumption. In addition, they generate inefficiencies regarding to the technical assistance, make impossible better improvement of the system performance, lead to irregularity water supplies and unsatisfied family users. Given the limitations imposed by the managers, low production and system failures, which results in constant breaking of the systems, the effective demand of saltfree water were restricted to the half of what the systems are able to produce.
