Levee Pipe Penetrations Inspections
In accordance with United State Army Corps of Engineers (USACE) Operation & Maintenance Manual (O&MM) regulations, it is required that the local sponsor of a Federally authorized flood protection system, perform inspections of all levee pipe penetrations on a five (5) year cycle. This work includes gravity outfall sewer pipes, utility pipes and other conduits contained and under the Wyoming Valley Flood Risk Management Project (WVFRMP). This effort is necessary in developing an understanding of the need to replace or rehabilitate a pipe, and selecting appropriate and economical solutions for deteriorated pipes.
The inspections are performed in accordance with the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment Certification Program (PACP) and the documents Guidance for CCTV and Sonar Inspection Pipes Penetrating Levees (USACE, November 2010), Guidelines for Human/Visual Inspection of Conduits (USACE, March 2012), and Guidelines for Video Inspection of Conduits (USACE, March 2012).
In January 2014, the Authority issued a Request For Proposals (RFP) for levee pipe penetration inspection services. From the responding firms, the Quad Three Group was awarded the contract to perform these services in the amount $142,800. The Notice To Proceed (NTP) was issued to the Quad Three Group in May 2014 and the inspection report deliverables were transmitted to the Authority in December 2014.
Levee Pipe Penetration Repairs and Maintenance Project
From the levee pipe penetration deficiencies and defects that were identified in the 2014 inspection reports for the Exeter, Forty Fort-Swoyersville, Kingston-Edwardsville, Plymouth and Wilkes-Barre-Hanover Reaches, the Quad Three Group developed the contract deliverables which included the construction drawings and specifications, which depicted the proposed repairs to the existing facilities.
Many of the deficiencies included the flushing or removal of debris, sediments and other objects from the interior of pipes, relief culverts and intake and discharge areas. In Forty Fort, work included the repair of a circular crack to a 36” reinforced concrete pipe (RCP) and a trenchless pipe rehabilitation to a 21” vitrified clay pipe (VCP) for a 240 linear feet length. In Plymouth, work included the repair of a circular crack to an 18” RCP and repair to an interior liner on a 24” RCP. In Wilkes-Barre, work included repairs to circular cracks to a 72” RCP. At all 13 pump stations throughout the system, work included wet well vactoring to remove accumulated sediments, debris, bricks and other unwanted objects.
At the September 2016 regular meeting of the Authority Board, after a public bidding process, A.R. Popple Construction, Inc., Wilkes-Barre, PA was awarded the $183,040 contract to perform the miscellaneous levee pipe penetration repairs and maintenance work. Substantial completion was achieved in January 2017 and post repair videos and photos deliverables submitted.
