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, the team determined that the surfaces above the waterline were deteriorated, so they lined them with 400 mils of Warren 301-14. They lined the surfaces below the waterline with 250 mils. Our crew completed 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, the team determined that all surfaces were significantly deteriorated and required 250 mils of Warren 301-14 epoxy. Following surface preparation, our team spent a full day stopping water infiltration stemming from active leaks. They chased leaks through multiple sections of walls with Warren's 151-HG grout. We were able to line this lift station and return it to service within three days. The average pull test values were over 950 psi.
