Watch Now

In most cases perception is reality; such is the case in the wastewater world. The centralized model is perceived to be the Cadillac and the decentralized model is perceived to be the “ugly stepchild”. Upon review of many measurement parameters the decentralized mode of wastewater treatment overturns these common misperceptions. The decentralized industry plays a large role in our nation’s infrastructure; over 25% of the United States relies upon decentralized systems to provide wastewater treatment. The designers, regulators and contractors of this industry should know the benefits to advocate and champion the industry.
