Evoqua Water Technologies Completes Acquisition of Frontier Water Systems

Pittsburgh, PA & San Diego, CA – Evoqua Water Technologies (NYSE: AQUA), an industry leader in mission-critical water treatment solutions, today announced that it has purchased the remaining equity of San Diego-based Frontier Water Systems, LLC. Evoqua initially announced its majority investment position in Frontier Water Systems in October 2019.

Frontier Water Systems is a leading supplier of engineered equipment packages for high-rate treatment of selenium, nitrate, and metals in water and wastewater. Waste streams from processes containing metals and minerals must be treated to remove these contaminants prior to discharge. Frontier delivers a biological process that safely removes these metals in a proprietary, modular bioreactor.

The business adds to Evoqua's portfolio of advanced wastewater treatment technologies. The terms of the deal were not disclosed.

"Evoqua and Frontier have successfully partnered on numerous projects to help solve the water treatment needs of our customers," said Evoqua Chief Executive Officer Ron Keating. "We are pleased to officially welcome Frontier to the Evoqua family, and we look forward to continuing to deliver on our commitment to provide our customers with advanced water treatment solutions."
