GF Piping Systems technology and its unique approach to business are an integral part of Akron’s plant improvement plans.

Located within the Great Lakes region and running along the Little Cuyahoga River, the City of Akron is the fifth largest city in the U.S. state of Ohio. The city’s century-old treatment facility serves over 300,000 customers throughout Akron and neighboring communities and routinely operates at about 35 MGD. The Akron treatment plant encompasses 1,200 miles of distribution piping and numerous processes including pre-screening, pre-oxidation, rapid mixing, flocculation, sedimentation, and chlorine contact. Treated water is then distributed across 25 rapid sand filters before it receives a final chemical addition.

In 2012, the EPA revised its turbidity regulations, which required Akron to reduce its 95 percent compliance level for turbidity from 0.3 to 0.15 nephelometric turbidity units (NTU), a reduction of its combined turbidity of 50%. Further, Akron was required to maintain a 95 percent compliance of 0.15 NTU on each of its 25 individual filters, a new regulation that had never been implemented prior.
