Cross-connection leads to wastewater discharge

St. Petersburg, Fla. (September 28, 2018) – After a routine investigation of the City’s Stormwater system, Water Resources staff discovered an inadvertent cross-connection made by contractors to a stormwater manhole at the Northwest Water Reclamation Facility (NWWRF).  This cross-connection occurred during installation of a new filter system for the plant at 7500 26th Avenue North earlier this year.   

After further investigation, it is estimated that 1.7 million gallons of water used to backwash the filters flowed into the stormwater drain – which conveys to a lake at Walter Fuller Park.

The unauthorized discharge was immediately stopped upon discovery of the cross connection.  Repairs to the line have been made the backwash water is now flowing back into the plant’s system for retreatment. 

Signs advising against any contact with the lake in Walter Fuller Park are now posted and thorough water quality testing is being conducted by the City’s Environmental Compliance Division.  Results from that testing will be posted on the Recreational Water Quality page https://www.stpete.org/water/waterquality.php.

Additionally, a complete investigation into how and why the cross-connection occurred is on-going with contractors and staff.
