Abstract

In this study, when the head connection pipe according to the fire safety standards of sprinkler facilities is connected to the side or the bottom, a study on whether the drinking water is properly managed according to the 「Drinking Water Management Act」 is directly collected from the target and general bacteria, total coliform group, iron, and turbidity were analyzed to determine whether drinking water is suitable for water quality. In addition to the evaluation of the results finally derived through this analysis procedure, we intend to present supplementary items and improvement plans in the relevant domestic laws and systems Basically, in this study, the sampling and collection of the fire extinguisher tank for the exclusive sprinkler facility was very limited. Among them, many samples were not secured because water was collected according to the year of approval for use of the building, and many of the fire extinguishers installed in the past use both the general living water tank and the fire water tank. There are parts where it is judged that it is a limitation to evaluate the whole with a small number of samples because there are not many samplings suitable for the among the six standards: standards for microorganisms, standards for inorganic substances harmful to health, standards for organic substances harmful to health, standards for disinfectants and disinfection by-products, standards for aesthetically-affecting substances, and standards for radioactivity Requesting results by limiting the results to the four items of the two standards: general bacteria and turbidity, etc. It is limitation of this study because it is difficult to make direct and large-scale comparisons due to the circumstances in which the collection cannot be performed unless the person concerned and the person involved in the collection cooperate. The head of the sprinkler facility can branch from the side or the lower part of the branch pipe, and the head of the sprinkler facility, which is the subject of comparison with 15 places, such as apartment houses, which is a fire extinguishing tank that must be managed at the same level as the water quality standard for drinking water, is installed as an upper branch, that is, a directional pipe, Samples were collected through individual visits for 15 sites by use that do not have a system for water quality standards, and they were commissioned to a specialized water quality analysis institution for comparative analysis. First of all, in the case of residential buildings, that is, apartment buildings, etc., in the case of the side or lower branch of the sprinkler facility that must be managed equally with the drinking water water quality standard, among the 15 subjects, the subjects with the general bacteria exceeding the standard were 8 places, more than half , in the case of an apartment house completed in 2011, the standard value exceeded the standard by a whopping 40 times, the total coliform group was also detected in 2 of 15 subjects, and in the case of turbidity, 2 subjects exceeded the water quality standards. Even though it should be managed equally with the standard, it can be seen from the analysis results that the maintenance inspection items are not stipulated in the self-checklist such as the comprehensive precision checklist, so that the drinking water quality standards are greatly exceeded. Next, for factories, neighborhood living facilities, and complex buildings, 5 places each for factories, neighborhood living facilities, and complex buildings among other targets that mainly use fenestration piping, which is a branching method at the top of sprinkler facilities, for which water quality standards are not institutionalized. In the case of general bacteria in 15 places, more than half exceeded the standard in 8 places, but in the case of a neighborhood living facility completed in 2017, it exceeded the standard by a whopping 80 times, and the total coliform group should not be detected. Total coliforms were detected in 4 subjects out of 15 subjects. In the case of turbidity, it can be seen through the analysis result that 7 of the 15 subjects exceed the water quality standards.
