Products for Septic Systems and Wastewater Treatment

What We Make

Orenco designs and manufactures advanced onsite (decentralized) wastewater technologies for individual properties and small communities -- properties that are not hooked up to centralized sewers, or whose sewers are failing or at capacity. Our products and systems allow treated effluent to be returned harmlessly to the environment via drainfield, lagoon, constructed wetland, or subsurface irrigation.
