PROJECT BACKGROUND

Northwest Regional Water Reclamation Facility (NWRWRF) had a series of new manholes previously lined with a protective coating. The original coating failed, causing the manholes to suffer from extreme corrosion. NWRWRF needed a product that would work. 

​

A&W Coatings was contracted to reline the manholes and rehabilitate the facility’s lift station with Warren Environmental’s (Warren) 301-14 high performance epoxy. Our crew sandblasted the manholes to remove the failed coating, followed by water blasting and acid etching. For each manhole, A&W rebuilt their four-foot diameter benches using brick and epoxy. The team applied a minimum of 250 mils of epoxy to all structures. 

​

Our application of Warren’s 301-14 epoxy provided a proven structural and corrosion-resistant coating to NWRWRF, saving them significant money on future repairs.
