A repeat client selected A&W and Warren Environmental's epoxy coating system to rehabilitate two lift stations in Plymouth, Massachusetts. Both were deteriorated due to the H2S gases present in the sewer system. In collaboration with the owner and their contractor, Robert B. Our Company, we developed a coating plan to return the lift stations to their original condition.

​

For lift station #1, it was determined that the surfaces above the waterline were deteriorated, so they were lined with 400 mils of Warren 301-14. The surfaces below the waterline were coated with 250 mils. Our crew completed the work and returned the lift station to service within three days. The average pull test values were over 1,600 psi on all surfaces.

​

For lift station #2, it was determined that all surfaces were significantly deteriorated and required 250 mils of Warren 301-14 epoxy. Following surface preparation, the A&W crew spent a full day stopping water infiltration from active leaks. They chased leaks through multiple sections of walls with Warren's 151-HG grout. In addition, the connective 5 LF of 12-inch ductile iron pipe was sanded and coated using a spray-in-place application technique. The A&W team lined the second lift station and returned it to service within three days. The average pull test values were over 950 psi.
