Incorporated in 1973, SEL is in its fifth decade of providing water treatment services and products to a wide range of industrial, commercial, governmental, and institutional users. In 2016, SEL expanded its offerings to include a plant-based water treatment program as a replacement option for their chemical treatment programs. This innovative approach to water treatment has positioned SEL as a leader in the industry's move towards more sustainable approaches to managing water.
Programs are administered by a team of water treatment professionals with extensive training and experience from a diverse background of water treatment companies and industries. Our water treatment company's technical support team averages over 20 years of experience in the water treatment industry. They are active and prominent in the water treatment related technical trade associations (AWT, ASHRAE, CTI, NACE) and most have earned the distinguished “Certified Water Technologist” (CWT) certification by the Association of Water Technologies (AWT).
