Electrical Instrumentation Technologist

Within the water and wastewater industry, Electronic Maintenance Technicians, also called Instrument Technicians, are responsible for installing and maintaining various electronic monitoring and communication equipment, including pressure and level recorders, programmable logic controllers, relays and computers. They are responsible for communications systems at treatment plants, pump stations, power generating facilities, electrical substations, and remote locations.



Electricians install, repair, operate, and maintain the electrical and power systems for homes, businesses, factories, and infrastructure within the water and wastewater industry. They are responsible for the wiring and control equipment through which electricity flows and the electrical equipment that it powers.



Engineering is an exciting profession that makes a difference in our world. Engineers play a critical role in providing clean, safe water to sustain life and support our economy. This includes planning, design and construction of new facilities as well as maintenance of existing ones. Engineering jobs in the water and wastewater industry provide the opportunity to earn a good living for yourself and your family while serving your community and protecting the environment.

“There are two things that make my job enjoyable. The first is the satisfaction of knowing that I am building infrastructure that keeps the environment safe from wastewater and pollution. The second is that even though this is a position in civil engineering, I am exposed to all of the other engineering disciplines…. This keeps the job interesting and allows me to learn about things that I might not otherwise be exposed to.” Chris Pachmayer, Union Sanitary District.

According to a workforce report by the Brookings Institute:

  • There are 212 different occupations in the water sector
  • In the US nearly 1.7 million workers fill jobs across the water sector
  • The water sector pays above average according to Brookings, up to 50 percent more for water workers in entry level jobs
  • California hires over 6,000 new water and wastewater professionals per year *
