This figure is a side view diagram of a partially submerged concrete liquid manure storage structure with a foundation drain connected to an observation and shut-off station. The storage structure in this diagram illustrates the storage wall, floor and foundation footing. A water-stop is shown between the foundation footing and the wall. A sealant is present in the joint between the floor and the wall. At the outside of the foundation footing, the foundation drain connects to an observation and shut-off station through a drainage pipe. The water collected in the foundation drain is channeled into the observation and shut-off station. The observation and shut-off station is an open top catch basin where the drainage water enters at approximately 0.4 meters above the catch basin floor. The drainage water then empties via a pipe with a 90-degree elbow directed upward to the top of the basin. A vertical standpipe is located above the 90-degree elbow. Should the drainage water from the catch basin need to be stopped, this vertical standpipe can be inserted into the 90-degree elbow.
