The Valdosta Daily Times
The City of Valdosta reported Wednesday evening that all manhole overflows resulting from Tuesday’s heavy rains had stopped, with the exception of two.
In spite of the heavy rain event which dropped between three to six inches this week, in addition to the several inches received last week from a separate rain event, the Withlacoochee Wastewater Treatment Plant remained in compliance and effectively processed the excess flows at the facility with no permit violations, according to the city’s report.
The WWTP, which was built to process eight million gallons of wastewater daily and has a capability to treat peak flows up to 12 million gallons, “was processing a peak flow of over 17 MGD on April 15, a direct result of over $2.5 million in sanitary sewer system improvements made recently at the WWTP,” according to the city’s statement. “The city’s MudCreek plant also processed the excess flows effectively with no treatment violations.”
However, the impact of stormwater inflow and infiltration into the wastewater collection system caused several manhole overflows in the city Tuesday.
“City crews responded immediately, and all but two of those manholes were stopped by 6 a.m., on April 16,” according to the city.
Below are the total estimates calculated for each of these major spills that entered the waters of the state. The city released these figures Wednesday evening.

An additional spill was discovered at approximately 5 p.m. Tuesday flowing in front of a home in the 2400 block of Berkeley Street. Stopped at 9 p.m., this discharge has been estimated at 12,000 gallons into waters of the state at Two Mile Branch.
“Clean up and disinfection has begun on all areas that have stopped flowing,” according to the city. “Upstream and downstream sampling will continue at the above locations to collect and document bacteria levels in the various impacted waterways. Public notice signs have been posted downstream from all spill locations, and the public is advised to avoid any contact with these areas.”
Valdosta Mayor and City Council are expected to award the Force Main project at the April 24 council meeting. This $32.7 million project includes more than six miles of force main, two minor and two major pump stations, a new headworks structure and a six million gallon per day flow equalization basin. Once awarded, the contractor has 30 days to begin the project, which means construction is expected to begin about June 1.
