Weekend Storm Results in Manhole Overflow
On January 2, 2021, the City of Valdosta Utilities Department responded to a call concerning a sanitary sewer overflow at a manhole in the 400 block of Mildred Street, an area that experiences localized flooding during rain events. The sanitary sewer spill was a result of excessive rainfall over a 24 hour period. This amount of rainfall over a short period of time resulted in storm water infiltration and inflow entering the collection system, and causing the manhole to exceed its capacity. Approximately 25,150 gallons of combined storm water and sewage discharged at this location, eventually entering into Dukes Bay.
It is important to note that this spill did not occur at the city’s Withlacoochee Wastewater Treatment Plant. During the storm, city infrastructure operated as designed. The Withlacochee Plant ran all four units plus the two excess flow equalization basins.
The city continues its ongoing effort to improve the infrastructure of the city’s collection system and eliminate these issues in the future. The city Utilities Department is currently working on an inflow and infiltration project that will identify sources of I&I, eventually eliminating excess flows into the sewer system during rain events. Sewer spills are not acceptable at any time. It has been the city’s top priority to prevent them all through the recent construction of the WWTP New Secondary Equalization Basin, as well as the Lift Station Rehab Program, Smoke Testing Program, Annual Manhole Rehab Program and the ongoing River Sampling Program that tests waters three times a week.
All appropriate regulatory agencies has been notified, and sampling of the impacted area will start immediately. Warning signs have been posted at this location as well as downstream to advise the public to avoid any contact with this waterway for the next seven (7) days. City staff have cleaned and disinfected the impacted area of this discharge.
