Abstract

This study evaluates the engineering and economic viability of implementing a rainwater harvesting system at Dr. Pirngadi Hospital in Medan, Indonesia. The assessment was conducted to quantify and evaluate how rainwater harvesting can contribute to reducing freshwater consumption and overall water demand in hospital operations to sustain- able water management in urban healthcare facilities. Using rainfall data, roof catchment measurements, and hydrological calculations, the total effective roof area was identified as 8,027 square meters with an annual precipitation of 3,421 millimeters. The estimated annual rainwater yield is 19,220 cubic meters, equivalent to 7.6 percent of the total freshwater demand of the hospital. The proposed system could reduce operational water costs by approximately 1,812 United States dollars per year with an estimated payback period of 2.4 years. The results demonstrate that rainwater harvesting represents a technically viable and financially beneficial approach to improving water efficiency and reducing dependence on municipal supplies. Beyond economic advantages, the system promotes environmental sustainability and resilience by providing a supplementary non-potable water source for cleaning, gardening, and sanitation purposes, highlighting the potential and significance of integrating rain- water harvesting systems into hospital infrastructure as part of a broader strategy for sustainable management of water resources in tropical urban regions.
