The drainage system usually consists of pipes in the floors of the foundation gallery and foundation tunnels. Periodic measurements of flow from the individual drains should be made and recorded. When flows from drains are minimal, measurements may be made using any suitable container of known volume and noting the number of containe..." current

The flow rate is usually recorded in gallons per minute. Compare the amount of flow with the amount of flow anticipated for the current reservoir level based on previous readings. A drain that has no flow..."
