Monthly Wastewater FlowsThe Transfer Pump Station pumped 13.639 million gallons in September. The chart below illustrates thechange in flow to Key Largo over the past year.

SalinitySalinity level exceeded compliance range per the interlocal agreement with the Key Largo WastewaterTreatment District on two days, due to seawater infiltration from the hurricane. The Village has notexceeded more than 30 days in the last year so there is no penalty for the two days in September. Achart tracking the September salinity readings is attached as part of the Severn Trent Report.

Executive Summary

As we know Hurricane Irma came ashore in Cudjoe Key at around 9:00am on September 10th as a CAT 4 Hurricane with sustained wind of 130 MPH. The Wastewater department had a plan and preparations started many days before the suspected impact. Our staff worked tirelessly to secure all of the Wastewater Facilities, and by the time mandatory evacuations were issued all of our facilities were secure. Our staff did not leave up until the very end to ensure any last minute issues were resolved.

Ones the storm past all of our staff was ready to come back to begin the recovery efforts.

Day 1 of Recovery

Our goal was to perform an assessment of all of the wastewater facilities to determine what major issues if any required priority. We identified that none of the facilities suffered any major damage, and quickly concentrated our efforts on the recovery of each vacuum collection system.

We started in North Plantation Key as this collection system was expected to have the most issues given that the system we have in the ground was so much more susceptible to flooding. After several hours the Vacuum System was back in a normal state. Some small minor issue remained but the system was working as intended and all of the system were free of water logging.

We moved on to Middle Plantation Key Pump Station. The system had very little issues and we quickly had it back to normal, and the same approach was taken with South Plantation Key which was recovered within a couple hours. By sunset NPK, MPK, and SPK were all in operation.

Day 2 of Recovery

Early morning our staff was back at it. We now were concentrating on Upper Matecumbe Key Collection System. This collection system had a lot more damage as storm surge on the ocean side covered many of the street with sand and debris. However, a game plan was in place. We isolated the collection system via the use of valves, and concentrated on bringing the system up section by section. This proved to be an effective approach as I was able to have more technicians in a smaller area thus allowing issues to be resolved a lot faster. By mid-Day the collection system was back to normal.

We then moved on to the lower Matecumbe Key Collection System. The same approach was used here as well. However, a large portion of this collection system was covered by sand and we were limited with access, but by the end of day 2 all of our vacuum system was for the most part back on line.

Day 3 of the Recovery

Islamorada Monthly Report Page 2

The focus for this day was to concentrate on assessment of E-1 Grinder Pump Systems. Therewere 394 Grinder Pumps that required our inspection so 3 trucks were mounted with generatorsand staff began the pumping down of E-1 stations and a detailed inspections performed. Basedon this initial assessment a detailed list was put together and repair parts were quickly put onorder, but for the most part by day 3 all of the Islamorada Wastewater Collection System wasback to normal operating condition.

My staff of 4 and I are very proud that we were able to get this large of a system back to normalwithin 3 days of a major storm coming through. This outcome is evident of a seasoned team thatis able to get the job done.

The weeks following have been a challenge as the Storm Cleanup Crews are causing damage tothe infrastructure. Countless Man Hole Lids, and Airvac Air Terminal have been damaged. As ourstaff performs preventive maintenance and issue are identified they are quickly reported andcontractor are dispatched to perform repairs.

SalinityThere were 2 days that we exceeded the 4.0 ppt salinity thresh hold. These exceedances weredirectly related to the storm as storm surge allowed for saltwater to enter Grinder basins, AirvacAir terminals, and Private system’s the pump into our collection system.

Attached you will find Chart indicating the exceedance.

Completed Work AuthorizationsNone to report.

Safety PerformanceWe continue to lead in the Southeast with zero recorded incidents and or lost time incidentssince December 2014. Severn Trent has a great safety program in place which requires a safetyboard in all facilities which helps to keep track of all daily safety tailgate meetings and providesall staff with online training courses.

No recorded incidents nor lost time incidents to report in the month of September.
