Convert the weight units, metric tons to kg:

15,000 metric tons = 15,000,000 kg

Then use the density of water of 1000 kg/cubic meter:

15,000,000 kg --> 15,000 cubic meters

Then convert the volume units, cubic meters to gallons:

15,000 cubic meters = 3,962,580.77 gallons per year

Now convert time units, year to minutes (this could depend on whether you look at an average Gregorian year or some other variation):

https://www.convertunits.com/from/year/to/minutes

1 year = 525949.2 minutes

3,962,580.77 gallons per year = 7.534 gallons per minute (GPM).

Note that if you did a simpler calculation assuming exactly 365 days (ignoring leap years), then there would be 525600 minutes in a year and that would give you 7.539 GPM or rounding to two digits, 7.54 GPM.
