The City of Valdosta
The City of Valdosta has reported that all manhole overflows that occurred since March 17 have stopped. The inflow and infiltration of stormwater into the city’s wastewater collection system resulted from the combined heavy rain fall since last weekend, completely saturated soils and abnormally high ground water tables. This influx of water caused the carrying capacity of the sewer line to be exceeded and resulted in sewer overflows at several manholes in the city.
Below are the calculated totals for all manhole overflows in the city since Monday, March 17. (Note: These are total amounts from ALL overflows resulting from this week’s event and include amounts already reported in a March 18 press release):
· A manhole in the 600 block of Scott Drive overflowed into Sugar Creek. The estimated volume of this overflow is 264,000 gallons. Overflow stopped on March 19 at 8 a.m.
· A manhole at the intersection of Mystic Street and Cypress Street overflowed. Wastewater entered the separate storm sewer system (MS4) which is a tributary to Knights Creek. The estimated volume is 69,000 gallons. Overflow stopped on March 18 at 11 a.m.
· Two manholes on the west side of Bemiss Road in the vicinity of Skipper Bridge Road overflowed. Wastewater entered Cherry Creek near Skipper Bridge Road. The estimated volume is 27,000 gallons. Overflow stopped on March 17 at 5 p.m.
· One manhole in the 2400 block of Meadowbrook Drive overflowed into Sugar Creek. The estimated volume of this overflow is 207,000 gallons. Overflow stopped on March 19 at 10:40 a.m.
· Two manholes in the 2400 block of Meadowbrook Drive overflowed into Two Mile Branch. The estimated volume from these two manholes is 3,000 gallons. Overflow stopped on March 17 at 2 p.m.
· A manhole overflowed on Lake Drive. Wastewater from this overflow entered Two Mile Branch. The estimated volume is 414,000 gallons. Overflow stopped on March 19 at 10:40 a.m.
· One manhole in the 2400 block of Meadowbrook drive overflowed into Sugar Creek. The estimated volume of this overflow is 138,000 gallons. Overflow stopped on March 19 at 10:40 a.m.
· Two manholes overflowed in the area between Remer Lane and Rouse Road. Wastewater from these manholes entered One Mile Branch. The estimated volume is 648,000 gallons. Overflow stopped on March 18 at 11 p.m.
· A residential cleanout overflowed in the 2500 block of Berkley Drive. Wastewater entered the storm water collection system and discharged to Two Mile Branch. The estimated discharge is 3,000 gallons. Overflow stopped on March 18.
Public notice signs have been posted downstream from all spill locations, and the public is advised to avoid any contact with these areas. Although, wastewater will naturally degrade over time in the environment even without treatment, city crews have been cleaning and disinfecting at these sites.
The city also reports that on March 19, at approximately 11:30 a.m., staff discovered a broken sewer main just north of a bridge on Gil Harbin Industrial Boulevard, adjacent to S. Patterson Street. A local underground contractor has been contacted to make emergency repairs to this main.
The city has planned, designed and bid a force main project and will award a $32 million contract in May that will prevent the majority of these overflows from occurring in the future. The city will also continue the smoke testing of the entire wastewater system, which began earlier this year, to identify and eliminate sources of stormwater inflow and infiltration that occurs during heavy rain events and that causes increased flows and possible wastewater surcharges in the system.
