Case Study
Staunton Water Treatment Plant, Staunton, VA
EFI installed a 46,760-square-foot floating cover, 13,056-square-foot slope liner and three floating baffles at Staunton's water treatment plant in 2003.
Historical scope checked against the original EFI Staunton case history on September 23, 2026. Reported material and schedule details describe the 2003 installation. The broader plant-capacity objective is not presented as a measured result of the liner and cover work.

The Challenge
Problem
The city's gunite-coated reservoir showed signs of leakage, and inspection of the nine-year-old floating cover found holes, tears and debonding seams. Hayes, Seay, Mattern & Mattern, Inc. provided the process and civil design for the plant improvements.
Our Approach
Solution
Environmental Fabrics, Inc. installed a 46,760-square-foot replacement floating cover, a 13,056-square-foot slope liner and three floating baffles using Seaman 8130 XR-3PW. The slope liner protected the cover from contact with the gunite surface. The baffles, one 197 by 19 feet and two 179 by 19 feet, were intended to increase contact time across changing reservoir levels. The case history describes these and other plant improvements as a program intended to increase capacity from 6 to 12 million gallons per day; it does not isolate a capacity gain from EFI's work alone.
