Pump
|-1 tank (raw)
|-6 water filters - tank (clean)
The output of the pump (150 L/d) appears to be evenly split in 7 parts (21.43 L/d), feeding all the filters at their max capacity (15 L/d * 6 = 90 L/d), but only feeding 21.43 L/d to the raw water tank.
I would expect the water tank to be filled at a rate of 60 L/d.
