About 2 years ago, El Paso Electric called PSC out to the Newman Power Plant to look at the evaporative pond liner. After 40 years, the liner had begun to deteriorate and needed replacement. PSC designed the 45-acre pond to be divided into 2 operational ponds. A 60 mil high-density polyethylene liner will be installed to replace the original 10 mil PVC liner.

“Longterm, it gives them better operational flexibility as far as being able to maintain the pond better,” said Dan Robillard, resident project representative on the project.

This time-lapse shows the progress of the project over the last 5 weeks. The first step of the project was to remove a foot of sediment that had collected on the bottom of the pond over the course of 40 years. The sediment was then pushed into piles, and the plastic was separated so that it could be disposed of properly. The next step is a mass excavation to lower the pond bottom about 2 feet from its prior elevation. The most recent work includes digging a footing for the dividing wall which will span 870 feet across the pond.
