Why no water at Silverton?

I have a bunch of DRGW Silverton depot trainorders from the late 1890's that show engines being authorized to run extra from Silverton to "tank" or "water tank" and return extra to Silverton. So presumably Silverton did not have a water tank then, just as it has not had in recent years. The closest water showing in my 1919 timetable, the oldest I have, shows a tank at Needleton (MP 484.4), which would make a 24 mile roundtrip to get water. Perhaps in the 1890's there was something closer. Since the orders would suggest that engines were often staying in Silverton long enough to need water, anyone have any ideas why the DRGW never put in a watering facility in Silverton....or did they at one time? Or why didn't they use the SN, SGN, or SR water...or did they. One of those trivial issues that might be fun to kick around.
