AIR-CONDITIONING CONDENSATE RECOVERY AND UTILIZATION AS AN ALTERNATIVE WATER SOURCE
In a tropical country with high temperature and humidity, water scarcity has been a problem for a long time. Millions of people lack access to a safe and sustainable water source. The increasing urban demand for freshwater continuously contributes to further depletion and deterioration of available water resources. This study considered options to attain efficient consumption by harvesting the air-conditioning condensate (ACC) as an alternative water source that fits its usage. A monitoring study in water quality and quantity of the condensate produced from thirty 2.5 horsepower window-type airconditioned units with 19˚C temperature setting and humidity of not less than 30%. Parameters such as lead content, total dissolved solids (TDS), Hydrogen Ion (pH), and microbiological analysis as to bacterial count, coliform count, and fecal coliform count were considered for quality analyses of harvested ACC, which conform with Philippine National Standards (PNS), Environmental Protection Agency (EPA), and World Health Organization (WHO) standards. The 34.20 liters average collected amount of ACC per day significantly reduced the monthly water expenses (p-value of lesser than 0.0001 at the two-tailed test) in the research area and saved money up to Php 16,869.40 from monthly water consumption with a cost-benefit ratio of 20.95% per year. The results revealed that ACC is a potential alternative water source as non-potable water that possibly contributes to the area's ecological track, considering opportunities for sustainability through efficient water use. The drive for sustainability is recommended for other agencies to harvest ACC as an alternative water source.
