Whenever anyone mentions Las Vegas, the first thing that comes to mind is The Strip. Lined with casinos, hotels, restaurants, and basically anything and everything you could ever ask for to keep you entertained for days on end, it’s understandably a prominent feature. However, if you venture just a couple blocks off the main drag, you’ll find the Las Vegas Convention Center.
At just shy of 2,000,000 square feet, it’s one of the largest convention centers in the world and the nation’s only convention center designated as a World Trade Center site. It hosts everything from international meetings and trade shows to sporting and special events for up to about 200,000 people. With numbers like that, and seemingly endless possibilities for the types of events the Las Vegas Convention Center can hold, day-to-day needs can vary considerably. This means that everything from electrical usage, HVAC demand, and water usage must be designed and built to accommodate heavy peak hours and off hours which typically happen on the same day.
When Environmental Systems Design (ESD) of Chicago, IL reached out to Metropolitan to design and engineer a booster pump system for the facility, we were up for the challenge. When we learned the project would require a system that could offer up to 2,300 GPM peak demand, we knew we’d be designing a large, multi-pump system. But it wasn’t the peak flow that was the challenge; however, it was the exact opposite.
Out of State, in Our Comfort Zone
A system with a 2,300 GPM peak flow rate is a significant design on its own, but creating a pump system that would also function efficiently and smoothly at just a few hundred gallons per minute and less added a twist to the project. Our experience with large convention centers, sports arenas, hotels, etc. has helped us optimize water booster stations where flow ranges can change drastically.
We can build pumps and systems to handle just about any flow rate a customer may need. That doesn’t mean, however, that every pump can handle the full demand range. For example, an 800GPM pump can easily move its capacity or share, but that same pump was not designed for low flow and can face damage or failure if it runs too slowly for any length of time. With a steady eye on a rate that could meet all flow demands based on a performance curve, we engineered a 7-pump design that was flexible enough to handle fluctuations and smart enough to do so without anyone giving it a second thought.
Each pump is rated at 375GPM, allowing for reduced flow without risk of damage. Though the individual pumps are on the small side, there was nothing small about the system. If you have already run the math in your head, you’ve probably figured that out. Hitting a maximum flow rate of 2625 GPM, we designed in a bit of cushion to account for growth, one-off spikes or a pump being off for service. Even the suction and discharge headers clock in at massive 12”, at least double the size of a typical booster system.
To keep everything running as smoothly as possible during different water usages, the system was complemented with the MetroTech III Pro. This customizable controller works round-the-clock to determine pump usage based on a set discharge pressure of 80psi. If one pump reaches 90-100% of its peak speed or if the pressure starts falling, the controller automatically calls another pump. The two pumps work in tandem, matching speeds to meet demands and minimize wear on any single pump, and the controller continues to bring pumps online until the full demand is met. Similarly, if pressure in the system is maintained and the running pumps slow down, the controller will shut them down one by one, naturally rebalancing the others. And, with a customizable MetroTech III, that’s just the basics.
Our controllers, designed and manufactured in-house, offer complete flexibility and control of a system and include trend logs that display system, pump activity and behavior. There is also the added option for cellular data connection to provide remote capabilities to your team.
Customers who choose to integrate remote capabilities into their systems have a secure connection that allows them to monitor their system on any browser device from wherever they are and whenever they need. And much like THE city that never sleeps, our alarm notifications are also dispatched by this technology any time of the day or night.
This remote capability also eases maintenance and much like a tel-a-doc visit, can allow Metropolitan to work collaboratively with your team to troubleshoot issues before needing to dispatch one of our 24/7 field service team members.
And while these state-of-the-art features no doubt can create more efficiencies, it’s also important to understand the risks associated with such technologies so risks can be mitigated right from the start.
Security and safety have always been a priority for Metropolitan and our remote systems use a multi-layered defense-in-depth approach to remote access along with other security controls to protect your water supply and end-users.
Communication and Commitment Regardless of Distance
Though we’re proudly based in Illinois, we’re no strangers to crossing borders and helping projects take shape in other states, too. Travel today does look much different than it did a couple years ago due to the COVID-19 pandemic that continues around the world, but that hasn’t slowed the water movement industry and it certainly hasn’t stopped us from bringing projects to life. Whether we’re working a few towns over or across the country, we strive for open communication and a collaborate approach within Metropolitan and with every customer.
From our earliest conversations with ESD to designing, building, testing, crating and being on site in Las Vegas to bring the system on-line, every step was carefully planned and executed with final launch dates in mind. For the teams at ESD and the Las Vegas Convention Center, that meant a seamless process from start to finish. For Metropolitan, that meant our Field Services Engineer knew exactly what to expect while arriving on-site and manually testing each variable speed pump individually and tested the entire system for automatic operation. That’s just business as usual. Regardless of how many miles may stretch between our headquarters and installation, we provide the same attention to detail, the same quality equipment, and the same commitment to ensuring everything we provide is exactly what you need (and probably a little extra, as well).
