Year Founded:

Founded in Chicago in 1928, Lakeside Engineering Corporation initially served the water needs of nation-wide buildings and municipal communities.  Lakeside's name sprang from our early location near the shores of Lake Michigan .  In 1968, we relocated to the western suburbs in Bartlett , IL , where we remain today.  

The first major products were Zeolite and Green Sand Water Softeners and Filters, and in 1936, the Aero filter was introduced as an early-day rotary distributor.  That same decade, a patent was acquired for the Spiraflo Clarifier, and later, the Spiravac Clarifier, SpiraGrit and Spiragester were developed.   

After the move to Bartlett , Lakeside introduced some of its most popular products.  Our engineers were the first to introduce brush aerators in the United States , later known as cage rotors.  The first open screw pumps in the U.S. were also launched by Lakeside, followed by our design of enclosed Type C and Type S pumps.  And in 1988, our liquid-solids screening separators were first produced.  These separators were the precursor to our Raptor®  line, which features the Fine Screen, Micro Strainer, Wash Press, Sewage Acceptance Plant and the H-PAC.  

 While our name was officially changed to Lakeside Equipment Corporation, our main role in wastewater treatment is that of process design and assistance.


A privately held corporation, Lakeside prides itself in its long-standing traditions of quality service and strong relationships with its suppliers, representatives, design engineers and employees.  Johnson Machine Works, our major fabricator, is nearing its 70th year working with Lakeside .  Many of our representative organizations have been with our company for nearly four decades, one since 1936.  Design engineers consistently choose Lakeside equipment for its efficient, durable quality and ease of operation.  And a dozen of our top employees have compiled more than 250 years of experience in this industry.
