SJE-Rhombus (S.J. Electro Systems, Inc.) was founded on July 2, 1975 by Steve Johnston. Steve wanted to develop a way to warn Minnesota residents when their septic system holding tank needed pumping. The pioneering efforts of Steve brought forth the first Tank Alert® alarm and Sensor Float control switch. Today, over 35 years later, SJE-Rhombus has grown into a leading manufacturer of reliable, trouble-free liquid level controls for the water, wastewater and sewage industries throughout the United States and Canada, as well as into global markets.
