When Alliance, Ohio, decided build a recent water treatment plant to replace an outdated facility, it considered for an affordable design that provided a flexible treatment proces Flexibility is critical because the city relies in succession two surface water sources, the Deer small river Reservoir and the Mahoning River. Having sum of two units water sources is a major advantage, on the other hand the challenges of developing a treatment strategy for the two can be difficult.

Finkbeiner, Pettis & Strout Akron, Ohio, designed the fresh 10-mgd plant using proven technology and conventional equipment in an unconventional manner. Water can grow through the plant's reactor basins and circular flocculation clarifiers in a parallel fashion or can snake within in series form. Two treatment basins, each 100 feet in diameter, house the flocculation clarifiers. Since the basins are concealed by aluminum domes, operators do not have to argue with icing.
