Equalization Basin at Withlacoochee Wastewater Treatment Plant (WWTP) Completed

After four months of construction, the City of Valdosta's Utilities Department has completed the new Equalization (EQ) Basin at the Withlacoochee Wastewater Treatment Plant (WWTP). The EQ Basin's need became apparent after the city experienced unprecedented rainfall in December of 2018. This caused the WWTP to ingest more than ten times the inflow's average amount, leading to a spill. The new EQ Basin helps alleviate this issue by providing the plant with an additional 7.8 million gallons of storage capacity.

The Withlacoochee WWTP was initially constructed in 1980 and was later rebuilt at a higher elevated location in 2016, where it still currently resides. In the winter of 2018, the WWTP, which is only designed to handle about 12 million gallons of wastewater a day, became inundated with an estimated 37 million gallons. At that point, city officials started initiating a program that would allow them to handle those additional flows, and out of that came the Equalization Basin.

 The Utilities Department began construction on the EQ Basin earlier this year in July. Utilities Director, Darryl Muse, says it has been a pretty seamless process from the start. "All the contractors, as well as materials, showed up on time. The city and utility contractor worked well together to make sure we got this done ahead of the anticipated rain events that South Georgia typically experiences in December and January," said Muse. Adding the additional 7.8 million gallons of storage capacity will allow the WWTP to take in the excess flows after the rainfall and pump that wastewater back through the treatment process to get it properly treated so that it can then be discharged.”

“The Equalization Basin Project has been a priority of mine since I took on the role of City Manager. We’ve been working hard to fund projects that will improve our utility system and prevent any issues that may impact our Withlacoochee River," said City Manager Mark Barber. "I am proud of Darryl and the Utilities Staff for working with EPD to get this project completed. This project shows our commitment to investing in and improving the aging utility infrastructure. We originally estimated this project to cost $2.3 million. Still, it actually came in under budget at $1.8 million, due to work that was done in the house ahead of time by our hard-working city employees.”

However, the Utilities Department does not rely on the EQ Basin alone to avoid overflows from heavy rain events.  In addition to this project, the Utilities Department also has the following projects underway:

The Utilities Department is out there every day getting a handle on the underground utility system's condition, so chances are when you see Maintenance Trucks out in the field, they are combating this problem. "We are fighting this on multiple fronts, and we are working hard to try and make sure we can handle anything that may happen. I won't say that we will never have an incident out there. You know nature is pretty relentless. Still, we certainly have come a long way to reassure that this facility will be able to handle any anticipated significant rain event that comes through," said Muse.  As a result of these efforts, residents should see an improvement in the wastewater system's performance.
