Destin Water Users Inc. was notified about 7:30pm Saturday night about sewer leaking from a lid on a lift station on Highway 98, near 1030 Highway 98.
Destin Water Users arrived on site just before 8pm to discover wastewater coming out of the valve vault lid of the lift station. Once the valve vault was opened a little after 8pm, it was determined that something had broken on the force main leaving pump 2.
The Florida Department of Environmental Protection was able to stop the flow by isolating the force main valve downstream about 8:25pm.
It is estimated that about 15,000-20,000 gallons may have escaped the valve vault during this time. According to the FDEP, the agency was able to
“recover about 3,500 gallons from the adjacent 2 storm drains on Highway 98 and have estimated that about 2,000 gallons percolated on site near the lift station, leaving a balance of about 9,500-14,500 gallons that may have gone into the stormwater system.”
Due to the Highway 98 resurfacing project, FDEP was unable to access the stormwater system to evaluate the extent of wastewater in the system. They checked the terminal location, stormwater separator on Gulf Shore Drive at about 9-9:30pm Saturday night and no wastewater had entered there yet. DWU did lime the area of the spill on Highway 98 before leaving the site Saturday night.
On Sunday morning DWU returned to check the manhole adjacent to the stormwater separator and found evidence of wastewater. FDEP pumped the manhole adjacent to the stormwater separator (~10,000 gallons) to remove any possible evidence of wastewater. The agency then checked the downstream manholes and the canal where it enters the harbor and have not found evidence of wastewater reaching the harbor.
FDEP will continue to monitor the stormwater separator for the next few days in an effort to remove any wastewater before it enters the harbor.
