I have a dataset that looks like this:

Code:
Date         Hour    Water
1/1/2020     2       5
1/1/2020     3       45
1/1/2020     4       63
1/1/2020     24      35
1/2/2020     1       24

I want to total individual instances of the number of hours and liters. Each "hour" represents an hourly interval on my measuring device. Each "water" is the number of liters of water that flowed through the device in that hour. Thus the desired output is:

Code:
Hours   Water
3       113
2       59

If there are missing rows of dates/hours or if there is a row where water=BLANK, we should assume there was 0 water. If there are multiple consecutive hours of water, then we assume that is one instance, so I want to total the number of hours and the amount of water that flowed. Is this possible to do with standard excel syntax? I tried various combinations of IF and SUMIF but couldn't quite figure this out.

What does custom number format of ;;; mean?
Three semi-colons will hide the value in the cell. Although most people use white font instead.
