In 1990, a group comprised of engineers, controls specialists, sales professionals, accounting and experienced production staff decided they wanted to make their mark in the industrial water treatment industry. A new company, headquartered and rooted in Milwaukee, called Lakeside Water Treatment, Inc. (LWT) was founded. From Day 1, the mission was to provide engineered solutions to companies that sell water treatment systems and service to industrial end users. As LWT finishes their 35th successful year in business, the equipment they have designed and sold has been installed all around the world.

LWT specializes in industrial water treatment systems such as softeners, activated carbon filters, multi-media filters, AG+ filters, condensate polishers, dealkalizers, deionization systems and reverse osmosis systems. LWT has had a long-standing reputation for designing and constructing the most durable equipment in the industrial market utilizing stainless steel, carbon steel and fiberglass tank systems. LWT offers custom engineered Control Enclosures with PLCs or microprocessors. Systems can be built with PVC, CPVC, galvanized, stainless steel, black iron or copper piping materials.
