Untreated Groundwater Causes Localized Discharge
ST. PETERSBURG, FL (April 21, 2017) – Today, as the city was pumping untreated well water into its water reclamation system to maintain pressure and volume of water available for irrigation, the flow of water from the well overwhelmed the sewer gravity line. This caused approximately 3000 gallons of groundwater to overflow from manholes near the area of the U.S. Coast Guard Station on Eighth Ave. SE.
The unauthorized discharge was stopped immediately upon detection and lasted approximately 30 minutes from 10:20 a.m. to 10:45 a.m. About 750 gallons was discharged into the adjacent storm drains, 1500 gallons was vacuumed up, with the remaining 750 gallons evaporating on the pavement. Workers will determine why the line was unable to handle the flow before using the well again.
The city is permitted to use supplemental wells to add water to the reclamation system to maintain supply in extremely dry periods when residents are using an increased volume of reclaimed water for irrigation.
