OUTFALL MONITORING

FSA Workshop – Sept 8, 2017

OUTFALL SELECTION

OUTFALL SELECTION

• Identify all outfalls entering waterbody• Determine drainage patterns discharging into each outfall via

pipe inverts and/or contours • Incorporate GIS and land uses for each sub-basin• Calculate pollutant loads discharging from each outfall• Per NPDES permit requirements, obtain permission from

Florida Department of Environmental Protection (DEP) to monitor specific outfall

LESSONS LEARNED

LESSONS LEARNED

1. Pre-existing conditions• Intact or damaged• Weirs upstream?• BMP’s upstream?• Volume of debris in system?• Last time maintained?

OUTFALL MONITORING

FSA Workshop – Sept 8, 2017

LESSONS LEARNED

1. Pre-existing conditions 2. Avoid surcharged system

• Data sloshy• Must hire a diver to install equipment and perform

troubleshooting & maintenance• Luckily, able to piggyback contract from SJRWMD• Make sure divers do not arrive with “HAZ MAT” truck >

causes panic in neighborhood

OUTFALL MONITORING

FSA Workshop – Sept 8, 2017

LESSONS LEARNED

1. Pre-existing conditions 2. Avoid surcharged system3. Silty conditions & flushing mechanism

• Interferes with sensors on flow meter• Installed 18” riser, but still inherited problems• Divers installed plug to clean lines; however, caused fish

kill within stormline and caused bad odors in immediate vicinity. Divers had to remove dead fish, as well as sediment and debris.

• Before install sensor, devise mechanism to flush, wipe or clean sensors on routine basis.
