The Remediator from Aquaworx by Infiltrator is an easy-to-install septic system remediation technology that can rejuvenate failing septic drainfields with minimal landscape disruption. Inserted into an existing septic tank, the aerobic bacteria will progress to the drainfield to reduce biological clogging and allow the effluent to infiltrate the soil. It requires nominal operation and maintenance cost. It introduces oxygen into a bacterial-growth media column, allowing bacteria to thrive and consume organic matter. These bacteria combine with the oxygen-rich effluent in the tank and move to the drainfield, reducing the clogging layer and the associated odors and wet areas in the yard. 800/221-4436; www.infiltratorwater.com.
