The volume of the reservoir will be equal to the volume of water filled by the pipe in the eight hours as exhibited in the graph

Thus the volume of the reservoir 

= Area of the region ABCDE + Area of region FGHI

= {(1/2)*20*60 + (1/2)*(10+20)*60 + 10*60 + (1/2)*10*60} + (1/2)*10*(60+180)

= {600+900+600+300} + 1200

= 2400 + 1200

= 3600 liters
