Learn more about how critical remote monitoring systems can be from the failure of Taum Sauk Dam (DamFailures.org)

It is increasingly common for water systems including dams and reservoirs to include digital instruments and/or controls. These types of systems can be used to remotely monitor the condition of the dam or water level in the reservoir, operate gates and valves, and regulate water flow and treatment. Since these controls are typically remote in nature, it is important to consider system reliability and redundancy, especially when the systems are critical to the safe operation of a dam.

-“Control consists of monitoring the state of a critical parameter, detecting when it varies from the desired state, and taking action to restore it. Control can be discrete or analog, manual or automatic, and periodic or continuous” (TM 5-601 Supervisory Control and Data Acquisition (SCADA) Systems for Command, Control, Communications, Computer, Intelligence, Surveillance, and Reconnaissance (C4ISR) Facilities).<ref name="TM 5-601" />

-“SCADA equipment installed in C4ISR (Command, Control, Communications, Computer, Intelligence, Surveillance, and Reconnaissance) facilities must be of such a design or otherwise protected to withstand seismic effects as well as shock (ground motion) and overpressure effects of weapons. A detailed dynamic analysis should be made of the supporting structure(s) of the equipment enclosures to evaluate the magnitude of motion and acceleration established at the mounting points for each piece of SCADA equipment. Where accelerations exceed the allowable limits of equipment available, the equipment should be mounted on shock isolation platforms.<ref name="TM 5-601" />

-“SCADA equipment should be protected from the effects of dust, dirt, water, corrosive agents, other fluids, and contamination by appropriate location within the facility or by specifying enclosures appropriate for the environment. Care should be taken that installation methods and conduit and tubing penetrations do not compromise enclosure integrity.<ref name="TM 5-601" />

+* [[Video Surveillance]]
-“Central computer or control rooms should be provided with dry agent fire protection systems or double-interlocked pre-action sprinkler systems using cross-zoned detection, to minimize the threat of accidental water discharge onto unprotected equipment.<ref name="TM 5-601" />
-“Sensors, actuators, controllers, HMI, UPS, and other SCADA equipment located throughout the facility should utilize enclosures with a minimum environmental protection level of IP66 per EN 60529 or Type 4 per NEMA 250. Where thermal management issues or other equipment requirements prevent use of such enclosures, alternate means should be provided to protect the equipment from environmental contaminants”.<ref name="TM 5-601" />
