[Certified Water Quality Testing Organization for Water Supply GLP] We strive for precision management as a testing company for drinking water quality in buildings.

【Water Supply and Simple Water Supply】 The water supplied by water service providers is subject to mandatory inspection under the Water Supply Act. 【Drinking Water Quality Inspection】 Specific buildings such as entertainment venues, stores, offices, and schools with a certain floor area must conduct drinking water quality inspections. 【Reuse Water Quality Inspection】 Water used for irrigation, landscaping, cleaning, and flushing toilets, which includes recycled wastewater, rainwater, treated sewage, and industrial water, is referred to as utility water. This utility water must be supplied with necessary sanitary measures in place. 【Water Tank Cleaning】 For water storage tanks with an effective capacity exceeding 10㎥, it is mandatory to conduct cleaning once a year and water quality inspections three times a year (once within six months × 2, and once for 12 disinfection by-products from June 1 to September 30).
