Shuixi Station was originally planned as the northern terminus of Line 4.^[5] At the end of 2010, the northern extension of the original Line 4 (Huangcun-Shuixi) was singled out and extended to both ends to become Line 21. In order to cooperate with the express positioning of Line 21, this station was cancelled for a time; Later, the setting was resumed during the EIA stage, and construction was finally implemented.^[6]

In 2016, the second phase of Plan 7 was extended to Shuixi Station as the terminal station, and then further extended to Shuixibei Station (now Yanshan). Line 21 was not initially scheduled have a transfer with Line 7, but at the end of 2016, the station design was changed to include a reserved transfer point with Line 7.^[7]

On 30 April 2019, the "three rights" transfer was completed on Line 21 of this station.^[8] On 20 December of the same year, the station was opened with the opening of the remaining section of Line 21.^[1] In order to coincide with the upcoming opening of the second phase of Line 7, the express train of Line 21 was adjusted to stop at this station since 29 August 2023.^[9]

In October 2023, the "three rights" transfer was completed at the Line 7 station.^[10] On 28 December 2023, the station part of Line 7 officially opened with the opening of the second phase of Line 7, and the station became a transfer station.^[11]
