A sewer line repair project along Deer Valley Drive will begin on Monday and run through the middle of next week.
Beginning 7am Monday, drivers should expect traffic barricades to be in place along Deer Valley Drive as construction begins on a sewer line repair project in downtown Park City.
The city says traffic will narrow into a slingle lane in each direction along the road but traffic control will be removed each evening, leaving all lanes on Deer Valley Drive open to traffic overnight.
The project will be repairing badly corroded sewer lines running along Silver Creek. Instead of replacing the pipes entirely, a corrosion-proof liner made out of fiberglass and resin will be installed instead. You may have already seen the liners sitting along the road this week.
Dan Olson is the Collections Systems Manager at the Snyderville Basin Reclamation District and says the liners are flexible when they are first installed before they are inflated and the resin is cured using ultraviolet light. He says this method does not require major construction and restores the pipe to nearly-new condition.
“So by using a liner like this, we can rehabilitate the line and bring it back to almost new standards,” said Olson. “We eliminate any digging in the road so we wouldn’t be tearing up the pavement, we’re not there for weeks at a time, we’re there for a couple of days. The disruption to the community is minimal.”
Olson says the liners have been in use since the early 1980s and should last just as long, or even longer than brand new pipes would. He adds the cost of liners versus new pipes is significant and was an easy decision to make.
“There’s good data that shows that these lines will last 30-40 years,” he said. “There’s not data beyond that because they haven’t been used much longer than that. Generally, a pipe you put in the ground, you expect to last 50 years and so these are most likely going to last just the same length as you would a new pipe, but the cost is probably a quarter to a third of what it would cost to dig and replace.”
The project is scheduled to be complete by Wednesday afternoon, October 21st.
