Disposal Field Recovery

Project Information

Date: July, 2003
Location: Fryeburg, Maine
Facility: Inn and Restaurant
Design Flow: 1500 Gallons per Day
Wastewater Type: Commercial

The owner of this upscale country inn and gourmet 45-seat restaurant contacted Aeration Systems, LLC to rejuvenate the existing disposal area serving the facility. The existing septic system was nearing the end of its useful life as evidenced by effluent ponding levels at the top of the concrete infiltration chambers.

Aeration Systems, LLC designed, constructed, and installed a treatment system consisting of an OxyPro 2000 processor tank set between the existing septic tanks and the disposal area.  The OxyPro 2000 was constructed completely offsite to keep onsite excavation and installation time to an absolute minimum.  This allowed the restaurant to remain open and avoid any costly interruptions in business.  The majority of wastewater trapped in the disposal area was removed by vacuum truck in order to speed recovery of the system.  The introduction of effluent with negligible biological oxygen demand (BOD) and suspended solids (TSS) and high levels of dissolved oxygen has eliminated any wastewater ponding in the chambers.

Specific Design Challenges

Rejuvenate Existing Disposal Area
Confined Area for Excavation
