In Too Deep?

Mount Sterling, Ky., utility uses PVC pipe buried to depths of over 25 ft

In Too Deep?

The Mount Sterling (Ky.) water and sewer system needed a 30- and 36-in. sanitary sewer trunk line to handle increases in local sewer flows in the Hinkston Creek area. The project required a high-performing sewer pipe to withstand the deep burial requirements—more than 25 ft in some areas.

“We historically have only used ductile iron pipe, but decided to consider Contech’s A-2000 PVC pipe due to its inherent corrosion resistance, long-term durability and proven history,” said David Pearce, general manager of the Mount Sterling Water & Sewer Department. “We were not disappointed. Previously, we had to use a ‘special coating’ with the ductile iron pipe in order to prevent corrosion.”

Taking into account the cost of material and production costs, A-2000 provided a lower overall cost than ductile iron pipe and saved the owner money.

“At first, we were a little concerned with the pipe being more than 25 ft deep, but we did the air and mandrel test of the entire 17,000-plus ft of pipe, and A-2000 passed every test,” said Cole Mitcham of CDP Engineers. “We are extremely pleased with A-2000 pipe and plan to use it again. The project was completed ahead of schedule and under budget—everyone involved with this project, including our client, is very happy.”

“We installed the A-2000 pipe faster than we were expecting,” said Philip Charles of Charles Contracting Co. Inc. “We finished the job ahead of schedule and increased the bottom line.”
