a discharge assembly mounted to the first port and comprising:
a discharge valve (50, 52); and
a first monitoring switch or sensor (230; 240) configured to monitor a characteristic of the discharge assembly; and
a first monitoring unit (100) coupled to the first monitoring switch or sensor of each said tank unit and configured to communicate with a remote monitoring location (800),
wherein the system further comprises:
for each of the tank units:
a second monitoring switch or sensor (260, 261, 280, 290) configured to monitor a characteristic of each of the tank unit; and
a second monitoring unit (340) coupled to said second monitoring switch or sensor and configured to communicate with the remote monitoring location; and
