Electrical engineers design large and small systems that use electricity, ranging in size from power generators to semiconductors. Water treatment and supply systems rely on electricity. So the reliability of the water supply depends on the reliability of the electrical equipment. Electrical engineers help:

• design, test, install electrical systems and electronic components, ranging from huge turbines to microcomputers;
• design and develop remote sensing devices for detecting leaks and locating underground pipes and sources of water;
• manage the electricity generated by hydropower, which is produced electricity when water flows over a dam and turns electrical generators;
• estimate the time and cost of engineering projects.
