Flovac’s Role at the Americas Cup. Eco-Sustainable Sanitation in Barcelona

/in /by

Barcelona is gearing up for the prestigious America’s Cup, the world’s foremost sailing competition, with Flovac playing a crucial role in ensuring eco-sustainability. Notably, four out of the six team bases in Barcelona will be equipped with Flovac’s advanced pneumatic sewerage network. This innovative system is designed for the efficient and eco-friendly evacuation of sewage and bilge water.

Flovac and the America’s Cup: A Sustainable Alliance

Flovac’s involvement in the America’s Cup, to be hosted next year in Barcelona’s port, highlights the company’s commitment to sustainable sanitation solutions. The cutting-edge pneumatic sewerage network, featuring vacuum valves, is recognized as the most energy-efficient sanitation system available today. It will serve four team bases, underlining Flovac’s dedication to environmental stewardship in major sporting events.

The competition will see five teams from the United Kingdom, Switzerland, Italy, the United States, and France vying to claim the iconic Hundred Guineas Cup from the current holders, New Zealand’s Emirates Team. The preliminary regattas, featuring the smaller AC40 boats, have already set the stage for next year’s climactic showdown in Barcelona.

The America’s Cup demands the highest standards, not just in sailing, but in all supporting infrastructure. Accordingly, Flovac has undertaken extensive modifications to its existing facilities at Marina Vela, Marina Barcelona 92, Marina Port Vell, and the Muelle Oriental. These upgrades ensure that the America’s Cup bases, all located in Barcelona’s Port Vell, receive top-tier sanitation services.

Flovac’s pneumatic vacuum valve system stands apart for its minimal energy consumption and airtight design, which effectively eliminates odors. Even in the unlikely event of a pipe burst, the system’s vacuum nature prevents spillage by drawing in outside air. This feature guarantees no environmental contamination, aligning with Flovac’s ethos of eco-sustainability and energy conservation.

International Experience

With a track record of successful projects in diverse locations like the Caribbean, the United States, Vietnam, and Australia, Flovac brings a wealth of international experience to the table. “We create bespoke projects tailored to the unique needs of each port,” says Bruno Galindo, Flovac’s Commercial Director. “Our system can be customized or entirely redesigned to meet specific requirements.”

The Flovac system addresses three key challenges with one solution: it efficiently manages wastewater evacuation from buildings, and also handles grey and bilge water from boats. As the America’s Cup teams begin to utilize Flovac’s vacuum systems, the event marks a significant stride in adopting eco-sustainable sanitation technologies in maritime facilities.

Automating air injection during tourism bursts

Vacuum sewer systems are highly resilient and adaptable, and the Water Corporation in Western Australia has shown how they have used technology in a clever way with the help of Flovac.

The Water Corp had a unique situation with one of their remote vacuum systems in the  town of Exmouth on Ningaloo Reef.

Regularly listed as one of the top 10 destinations in Australia, tourism pressures has led to increased flows in the town during peak tourism seasons.  In particular, this year saw the towns population increase from 3000 people to 30,000 people as it became the centre of a solar eclipse global event. This included a great video incorporating the 50th anniversary of Pink Floyds, Dark Side of the Moon

How does any sewage system cope with massive variations in population? If you size it for peak, then sewage will not flow during the off peak periods. If there is a big increase in flow there could be overflows. Overflows in such a pristine location was not an option. Vacuum systems operate on a pressure differential which manages a complex mix of air and water. Systems are all designed for a specific air to liquid ratio. If there is too much air, then either you get very high energy costs with increased pump runs, or flows that don’t carry efficiently to the station. Too much liquid and there is a risk of overflows, or capacity issues at the rising main (force main) or treatment plant (discharge point).

Flovacs wireless monitoring system has a unique feature. The ability to alter the air to liquid ratios within the system. Programmed into the networks, different valves can be programmed to alter the mix to either increase or decrease the amount of air required along the vacuum main, changing the air liquid ratio. In dealing with seasonal issues, like Exmouth, or in areas that can get inundated by too much water via hurricanes or storm surges like Key Largo, Florida, the ability to change the air to liquid ratio becomes an important tool for managers and operators. It is fantastic that monitoring can identity infiltration, but it is essential that we give the operators the tools to handle the system when it occurs.

Last month Rajiv Narendranathan , from the Asset Management Team for the Water Corporation presented a paper at the AWA (Australian Water Association) conference in Darwin. The title was IMPROVED PERFORMANCE OF VACUUM SEWERS WITH PRESSURE MONITORING ALONG VACCUM MAINS AND PROGRAMMED AIR INJECTIION BASED ON PRESSURE TRENDS.

In his talk Rajiv said

Exmouth is approximately 1,100 Kms north of Perth and about 550Kms south-west of Karratha and the remoteness of this town makes it challenging to operate. Exmouth has a population of 2,500 people however as a tourist town the population can increase to about 6,000 people during peak holiday periods. The extreme variability in population results in unpredictable flow patterns which make the vacuum system in Exmouth near impossible to tune. Without appropriate levels of air being sucked into the system to cater for increased flows the vacuum lines are flooded and the pressures crash resulting in wastewater overflows.

Flovac AAI air injection success

The FLOVAC system monitors pressures along the Vacuum line in Exmouth and this improved visibility has enabled the system to be tuned to respond to variable flows from the catchment. The ability of this system to monitor pressures and inject air into the line appropriately has resulted in the air/liquid ratio being maintained during peak demand periods and maintain pressures throughout the vacuum line preventing wastewater overflows.

 

The project and rollout was a tremendous success and is being rolled out to numerous other projects in Western Australia. Flovac has used automated air injection systems at many projects around the world over the last twenty years.
