U.S. Water’s knowledge of the Little Venice facility precedes its current contract
operations with Marathon. The Florida Keys Aqueduct Authority maintained previous
ownership of the facility. The FKAA engaged U.S. Water in 2005 to provide proper
analysis of the condition and operating status of the Little Venice WWTP.
At the same time, the FKAA requested evaluation since the facility was out of
compliance with regulatory sampling requirements. After the evaluation was
completed, a report was provided which contained information as to the current
operational condition of the facility, identifying specific treatment deficiencies within the
system specifically as it relates to total nitrogen violations. It also contained a general
overview of the facility compliance.
Recommendations were made and implemented by U.S. Water, which was later
contracted to provide professional operating services and directly maintained
compliance at the facility for a period of 12 months, and authored standing operating
procedures.
In 2009, U.S. Water successfully completed start-up at Marathon’s Area 6 facility
(Coco Plum), while in 2010, start-up of Marathon’s Area 4 facility also was completed.
U.S. Water currently operates three wastewater treatment facilities and associated
collection and stormwater systems for the city.
Key Colony Beach 0.34 MGD Zenon Wastewater Treatment Plant –
Key Colony Beach
Project: N/A
Owner: City of Key Colony Beach
Owner Contact: Eleanor Morton, P.O. Box 510141, Key Colony Beach, FL 33051
U.S. Water took over operations and maintenance of this system in March 2010,
which was previously operated by Synagro Corp. It also was once the premiere zenon
wastewater treatment facility in the world, hosting visitors from many countries to see
the operation.
The existing two-train wastewater treatment plant has a permitted treatment capacity
of 0.34 million gallons per day annul average daily flow. The treatment and disposal
system consists of 2mm influent screens, two 27,750-gallon anoxic tanks, two
37,000-gallon aeration tanks, and two 34,350-gallon MBR aeration tanks with eight
membrane bioreactors.
It also includes one 100,000-gallon digester, five sludge drying beds with a total area
of 6,500 square feet. It also has two closed-channel ultraviolet disinfection units, one
28,000-gallon effluent polishing tank, one 120,000-gallon reclaimed water storage
tank, and one reverse osmosis effluent treatment unit for public access reuse.
