We noticed some sewer work at the Turner Farm on Franklin Road and thought drivers might be curious about what workers were doing.
We noticed some sewer work at the Turner Farm on Franklin Road and thought drivers might be curious about what workers were doing. We called Todd Spangler, assistant director of Brentwood Water Services to find out what’s up with that?
The city has been completing overall sewer rehabilitation work since 2007 as part of an order issued to the city by the Tennessee Department of Environmental Conservation.
The Water Services Department has been monitoring the flow of sewer lines and prioritizing the city’s older pipes to reline them, keeping out rainwater and runoff water.
Brentwood does not treat its sewage, but sends it to Metro Nashville, which places a daily 9.5 million gallon capacity on the city.
When rainwater or runoff water from streams seeps into the sewer lines, it decreases the efficiency of the sewage capacity.
“We want to get the pipes to the most efficient use of our sewer lines,” Spangler said.
Additionally, Metro Nashville charges to treat the sewage it receives from Brentwood at a cost of $1.92 per thousand gallons.
“There’s no point in treating rainwater,” Spangler said. “The goal is to tighten the system up.”
When drivers saw green pieces of equipment attached to pipes, Spangler said, the workers were bypassing the sewer flow in order to repair the pipes.
The older pipes, made out of clay and concrete, are more susceptible to cracks and damage.
Spangler said the work at the Turner property was the last project for the year, but a few others were scheduled for the spring.
Additionally, Brentwood’s Board of Commissioners approved an agreement with CH2M Hill Engineers on Nov. 25 to prepare a final sewer report. The report will publish flow data in 2014 to determine if there has been a reduction in sewage and an increase in efficiency.
