Description
Summary:Self-supply of drinking water is implemented in areas where the coverage of piped water services is inadequate, low incomes residents, and poor performance of piped water supply. The Life Cycle Cost (LCC) is a method of evaluating all costs incurred and is used to track the financing of the drinking water sector. This study analyses LCC of self-supply water in the Metro City, Indonesia. A field survey was conducted using a questionnaire in October 2020 for households in Metro City that captured information on costs incurred for household water use. It was observed that self-supply water uses in Metro City accounts for 92.86.30% of all water supplies. The average recurrent expenditure is Rp.224,344/ year with mean of capital cost is Rp.275,273. Most expensive cost for self-supply is borehole. High cost of borehole due deeper groundwater source, borehole use more pump electricity and higher drilling cost. This funding for selfsupply water is carried out independently by the households. These results highlighted the importance of self-financing for the water supply sector. Increased reliability and safety of self-supply require a better awareness of the costs and benefits of developing water sources. Furthermore, selfsupply water requires better governance to achieve safe water access.
