ABSTRACT
This study was undertaken to determine the quality of bottled water produced by the 40 Water Refilling Stations (WRS) of Zamboanga City.
Water samples were collected from every WRS of Zamboanga City. There were three different sources of samples: (1) the product water (water produced after the water purification process); (2) the wash water (water used to wash the empty bottles), and; (3) the bottled water (water packaged in 5-gallon bottles). The physical and chemical analyses of the product water samples from all the WRS’s were within the Philippine National Standards for Drinking Water, while the Bacteriological analysis of the product water and wash water samples were free from Total Coliform. However, bottled water were positive for Total Coliform in 70% of WRS’s. Such contamination is attributed to the inadequate washing and sanitizing of the empty bottles submitted by consumers to WRS for refill, and poor hygiene of WRS’s personnel. While the presence of Coliform in the bottled water indicate possible fecal contamination, drinking it does not necessarily equate with contracting serious illness. It does however suggest the risk of contracting waterborne illnesses especially among immunocompromised persons. 1

CHAPTER I
INTRODUCTION
Background of the Study

In the recent past decade, one of the most popular industries that has boom is the water refilling station (WRS) business. Water Refilling Stations are small water systems that have its own water purification facility producing potable drinking water in 5-gallon bottles. These stations purify water sourced from either a private deep well or a water line tapped from the local public water system. With an affordable amount as a capital investment, many opted to establish this kind of business. Today, the water refilling stations has widely spread that one can see one station almost in every corner of the city. The City Health Office of Zamboanga City records 54 operating water refilling stations as of November 2007.

Together with the widespread of these WRS’s is the increase number of its consumers. There are many factors that opt the public to patronize this commodity despite its high cost compared to the potable water from public water system flowing thru the household faucet. In developing Countries like the Philippines, demand for this water source is driven by factors like convenience, the perception that bottled waters are safer than the local piped water system, and taste preference.

To lure consumers many of the WRS’s entrepreneurs use marketing strategies like offering free hot and cold water dispensers and free deliveries, packaging and...
