Administrative Region
The area overseen by this station is bordered by Shetou Township to the east, separated by the Babao No. 1 Canal. To the west, it meets the Xizhou Workstation, defined by the Dongbeidou Zhongzun Drainage. The southern boundary reaches Wubo Village in Ershui Township, while the northwest extends to Muyi Village in Tianwei Township, close to the Tianwei Workstation. The region stretches about 4.5 kilometers from the Babao No. 1 Canal to the Zhongzun Drainage in the east-west direction, and approximately 12 kilometers from Ershui Township's urban area to the north-south.

Irrigation Water Source
The main sources of irrigation water in the area include the Babao No. 1 Canal and Babao No. 2 Canal. The Babao No. 1 Canal serves areas like the Xiangshan Canal and the Xinshiwu Main Supplementary Canal, which also supplies water to the Guozhen Second Canal.
Meanwhile, the Babao No. 2 Canal irrigates regions including the Guozhen Second Canal, Daxin Canal, Liujia Canal, Shiwuzhuang Canal, Shiwu Supplementary Canal, the Old Erfen Canal, and the Nanzhenping Line. Generally, the water supply for irrigation is adequate, although many areas have undergone lining work to support the irrigation system.
For drainage, the region is served by Tianzhong Drainage, Daxin Drainage, Meizhou Drainage, Muyi Drainage, Waisan Drainage, San’an Drainage, and Longtan Drainage.

Irrigation Region
During the Japanese colonial period, this area was under the Tianzhong Office. After Taiwan’s retrocession, it became part of the Babao Water Conservancy Committee. In December 1956, it was reorganized under the Changhua Irrigation Association and named the Tianzhong Workstation. On October 1, 2020, it was further restructured as the Tianzhong Workstation under the Changhua Management Office, with an irrigated area of 1,117 hectares.
