  3. The construction of water resources center, the construction of pipe network system, the construction of user connection and the subsequent operation and maintenance are all operated by the company team. The company's team technology covers the entire life cycle of sewage sewer construction design and drawing.
  4. In June 2020, the number of connected users was 30,223. The construction quality and performance were highly praised and affirmed by the Miaoli County Government.
