​   ​One of the key elements of medieval urban infrastructure was the underground water supply system. The total length of the gallery is approximately 50 meters, its width is 1.5 meters, and its height is 2 meters. Two parallel rows of ceramic pipes laid through the gallery supplied water to the bathhouse. The diameter of the connecting pipes is about 20 centimeters.
   The external section of the gallery, which originated from the city’s reservoir, has collapsed, while the part located closer to the bathhouse remains well preserved in its original form. 
    Archaeological studies have shown that the water supply system operated for a long period of time, undergoing maintenance and alterations to its layout over the years. 
    The cultural layers excavated at the site date back to the period before the 14th century. Most of the ceramic and glass artifacts found in the construction layers belong to the Karakhanid era (10th–13th centuries). This evidence indicates that the gallery and the adjoining bathhouse complex were actively used during that time. After the bathhouse complex ceased to function, its territory, including the gallery section, was converted into a cemetery. This phenomenon illustrates the transformational nature of sacred and public spaces within the medieval urban environment.
