The Murfreesboro Water and Sewer Department (MWSD) began reconstruction of a sewer main under State Street from Highland to Bilbro avenues on this week.
Weather permitting, the project is expected to continue for approximately three to four months, MWSD engineer Valerie Smith said. Crews will start at Highland Avenue and work east to Bilbro one block at about two to three weeks per block.
Residents in the immediate construction area or block will continue to have access to their homes, the release states. Construction will occur one block at a time but traffic flow will be maintained through the remaining blocks.
No formal detours are planned because of the grid nature of the area, Murfreesboro Traffic Engineer Ram Balachandran said. Drivers will be able to tell how to get around the intersection.
When construction is complete, the street will be paved.
MWSD continues to rehabilitate and repair the Murfreesboro sewer system.
“We have two methods of accomplishing this rehabilitation,” Smith said. “The first is a bi-annual rehabilitation contract with Insituform Technologies, whose services include a trenchless method of repairing the existing pipe from the inside out.”
“The State Street rehabilitation will be completed by the second method,” she continued. “Crews from our Operations and Maintenance Division actually dig up the old line and replace it with new.”
In addition to State Street, the other streets within the area will continue to be rehabilitated by Insituform Technologies. The company’s less invasive process results in minimal excavation, which helps minimize the inconvenience to residents because no road closures are required.
“Periodic disruption of a resident’s sewer service will be between two and 10 hours,” she said. “The sewer line between the main sewer line in the street and the cleanout connection at the property line, will be repaired by the same method as the sewer main, whether it was trenchless or by the dig and replace method.”
If any digging is required when the cleanout at the property line is replaced, she said, the disturbed area will be allowed to settle for up to two weeks. Once that has occurred, top soil, grass seed and a straw covering will be applied.
“Workers will check back in several weeks to make sure that grass is growing,” Smith said. “In all, the entire project should be finished in 120 days with minimal disruption to customers.”
Questions about the State Street work may be directed to Terry Taylor, MWSD Operations and Maintenance Department, 848-3218, she said.
“Call me at 848-3200 if you have questions about the remaining areas,” Smith said. “For more information on the technique used by Insituform, visit the company’s Web site at www.insituform.com. |
