To address the daily water needs of passengers at Baoshan High-speed Rail Station in Yunnan Province, an integrated smart pump room water supply equipment set was procured. Given the limited land area at the station, Zhongying Water Supply Equipment designed a specialized outdoor pump room combined with water supply equipment, achieving both land-saving and cost-effective solutions in both construction and operation. This innovative approach has been well-received by the users, demonstrating its effectiveness in optimizing land use and reducing associated expenses.
