Marion Count, Building Insp ection Division Onsite Septic Review OREGON PUBLIC WORKS Activity Number: 555-19-000643-INQY Date: February 21, 2019 Project Address: 17124 South Abiqua Road NE, Silverton Parcel 'A,' Partition Case 18-032; 1.3. Acres of TL 061E29DB00100 Completed By: Matthew Puntney, REHS RECORD REVIEW This existing system review was conducted in response to application for Partition Case No 18-032. This review is for the residence and system on Parcel A. Installation Permit Record: Marion County has no records regarding the installation of the system serving this residence. Components and Function: The tank was pumped by Farmers Septic on January 11, 2019. The pumper noted a 1200 gallon tank and no signs of failure. The baffles appear to be in need of replacement. Lone Pine Corner Septics, Inc. evaluated the drainfield on January 15, 2019. The technician noted approximately 60 linear feet of serial drainline and no signs of failure. A site visit was conducted on February 15, 2019. The system was in use and showed no signs of failure. The system had been electronically located and flagged. The drainfield does not meet setbacks to the ditch and is likely undersized for the existing dwelling. Drainage from a pond ran very close to the ends of the drainlines. A test pit was evaluated to establish an area for a repair system. The area around the pit is suitable for a STANDARD SYSTEM. Please refer to the field worksheet for further instruction detail. The septic system area should be protected from any vehicular traffic, livestock and farming activities. Other activities such as logging, excavating or filling, driveway placement or any similar activities may damage the soil in the area of the drainfield and adversely affect system function. A RISER TO THE GROUND SURFACE IS STRONGLY RECOMMENDED TO FACILITATE EASIER PUMPING. The septic tank should be pumped and inspected by a licensed septic tank pumping service when sludge and scum accumulation reaches 30% of tank volume. Pumping every 3-5 years is an average interval. The septic tank is a reservoir for the solid materials in the sewage waste stream. Excessive accumulation of these solid materials in the septic tank will cause the solids to wash out of the tank and into the drainfield. This will cause irreversible damage to the drainfield and will eventually lead to a system failure. Disclaimer: This evaluation report describes the on-site system as it exists on the date of inspection and to the extent that components and operation of the system are reasonably observable. Oregon Department of Environmental Quality and Marion County recognize that this evaluation report does not provide assurance or any warranty that the system will operate properly in the future. 5155 Silverton Road NE- P.O.Box 14500—Salem,Oregon 97309-5036--Phone(503)588-5147—Fax(503)588-7948 D.rnz.1 ..F 1
