Escherichia coli bacteria found in refilled drinking water shows that the quality of the drinking water does not meet the requirements of drinking water refill depots (DAMIU) set by the government, both in terms of bacteriological examination and human resources. It is probably caused by poor equipment maintenance as well as irregular sanitation and hygiene measure by the owner. According to Permenkes No 492/Menkes/PER/IV/2010, one of the requirements of drinking water is said to be consumable if the total content of Escherichia coli bacteria is 0 per 100 ml.

By employing a total sampling technique, a total number of 15 DAMIU served as research samples.
