Completion Ceremony for Shiroyama Water Purification Plant Renovation

On March 30, 2023, Watering Engineering Co., part of the Watering Group, attended the completion ceremony for the major renovation of the Shiroyama Water Purification Plant in Joetsu City. The event underscored the company's commitment to enhancing local water infrastructure and was attended by local government officials, including Joetsu City Mayor Junichi Kosuge and various stakeholders from the community.

During the ceremony, Watering Engineering received a letter of appreciation from Kazunobu Takahashi, the project manager from the Joetsu Gas Waterworks Bureau. This recognition highlights the collaborative efforts that characterized the renovation project, a testament to the importance of public-private partnerships in urban infrastructure development.

Background of the Project

The Shiroyama Water Purification Plant serves as the largest water supply facility in Joetsu City, providing drinking water to approximately 60% of the city’s residents prior to its merger. Since its completion in 1968, the plant has faced challenges of aging and operational demand, prompting the Joetsu Gas Waterworks Bureau to initiate a significant renovation in the fiscal year 2021. The project utilized a Design-Build delivery system to streamline construction, and after a thorough selection process, Watering Engineering, in partnership with Tanaka Industries, was chosen to carry out the project.
