In a perfectly flat world, a community’s potable water pressure would be maintained with a water tower using little more than the force of gravity. However, we all know the world is round, and when water needs to make its way across – or, more accurately, up – more rugged landscapes, delivery becomes complicated. To help overcome this challenge and ensure adequate water delivery across difficult terrain to more rural areas, booster pumps are used; however, these pumps tend to come with their own set of challenges.

Though standard booster pumps have typically met the basic expectations associated with water delivery, they often leave a lot to be desired, especially when considering packaging and protection from the elements. Further, from the perspective of the water operators who are tasked with servicing these pumps and related components, standard booster pumps are far from perfect.

The Problem

In typical waterworks applications a booster pump package is enclosed in a fairly small fiberglass tilt-up enclosure (a clamshell case). From the standpoint of surface area, these packages are great because they maintain a small footprint, but that footprint comes at a cost the operators must pay. Fitting all necessary components into such a small space with a single access point complicates maintenance. Because access is limited, simple tasks are often made difficult and when working in the field – and in the elements – that is a problem. Then again, working in the elements can be a problem for these enclosures, too.

Despite the appeal of fiberglass, these shells often do not hold up well over time when exposed to cold temperatures, blazing sun, and whatever else nature may bring. As the material begins to become brittle, the critical components it contains are at risk. Further, by their very construction and size, these cases do not allow for additional equipment that can help the overall longevity of the product, such as internal climate controls. With these limitations, it is easy to ask one simple question: Why are these tightly-packed, fiberglass-bound systems in use?

The answer is simple: For a long time, this booster package was the only option and the industry as a whole stuck with the classic, “If it’s not broken, don’t fix it,” approach. Though that motto works for a lot of things, it did not work for us. Metropolitan recognized the inefficiencies inherent to existing booster pump systems and the need to focus on both the basic functions and overall serviceability, ease of use, and the operator experience. In other words, we knew there was a better solution and we knew that this better solution would involve more than just a functioning pump.

Back side accessibility of XTB


Performance Comes Standard

Metropolitan’s XTB Booster Pump System is designed to deliver water to hard-to-reach locations while streamlining the operator experience. With the reliability of our time-tested pumps (available as 2” with flows up to 60 gpm and 3” with flows up to 140 gpm), ensuring the flow of water was easy. To guarantee that our XTB System would be broadly compatible, we also designed our 2” version to run 7.5hp pumps on single-phase or three-phase power as the latter is not always a cost-effective option in rural areas. Finally, every XTB is built into an insulated steel enclosure that allows for better ingress protection and control of the internal environment when compared to most clamshell cases. This enables the system to maintain an ideal environment for our efficient, variable frequency drives through the inclusion of an air conditioning unit and two 1500 watt redundant heaters.

But we did not stop there. For our XTB Systems to offer real value to the market, something that recognized the needs of those accessing the water and those servicing the system, we designed the XTB with the operator in mind. By designing a more accessible enclosure layout, water operators working with the XTB can easily access whatever they need without having to work through or around other components. Back to back access doors help make this possible, but we also eased troubleshooting for the life of the product. When maintenance is required, Metropolitan’s intuitive touchscreen interface eliminates keystrokes and walks the operator through every process, much like an ATM.

With the manual built directly into this electronic interface – eliminating the need to lug around and keep track of a paper copy – all necessary information is at the operator’s fingertips when and where they need it most. Finally, every XTB Booster Pump System also comes standard with remote monitoring free for six months to simplify the critical pump station commissioning phase. Remote access brings all status, alarming and adjustability available through the on-unit touchscreen directly to Metropolitan and the operator’s computer or mobile device. All alarms, sent by SMS or email, can even be remotely acknowledged, letting the operator know when remote or on-site access may be required.

The real measure of success for a booster pump may be its performance in the field, but at Metropolitan we know that performance often hinges on an operator’s ability to provide necessary servicing. And with the XTB, we are making the operator’s job easier than ever by providing a much needed boost.


Metropolitan Industries supplied a factory pre-fabricated potable water air gap pump skid to the Silicon Valley Advanced Water Purification Center In San Jose, Ca.

Metropolitan Industries prides itself on having an industry focus on projects that help with the quality of public water systems. Our recent involvement in the Silicon Valley Advanced Water Purification Center focused on the greater Silicon Valley community, reshaping the recycled water industry as a whole.

The Silicon Valley Advanced Water Purification Center (SCAWP) is one of the largest water purification plants in northern California. The facility purifies treated wastewater effluent using three proven processes – micro-filtration, reverse osmosis and ultraviolet light. The purified water is then blended with the existing recycled water supply produced at a neighboring facility. The SCAWP aims to improve recycled water quality and increase water reliability; therefore creating a locally controlled high quality water supply.

As part of a recent potable water line project at the Purification Center, Metropolitan Industries supplied an air gap break tank booster pump package. Air gap pumping systems are used to protect water supplies from potential contamination. The air gap assembly and break tank provide a positive disconnect from the water source to down steam water connections. The pumps and controls that were provided as part of the complete factory prepackaged system are necessary to re-pressurize the potable water supply for use throughout the facility. The factory built system, which was designed to be installed outdoors, includes three vertical multi-stage pumps, piping, valves, electrical controls and a plant wide SCADA system interface.

Overall, the SCAWP system is a unique project to combat the nature of water conservation and water consumption for the Silicon Valley. Metropolitan Industries’ involvement with Silicon Valley Advanced Water Purification Center helps Metropolitan gain insight about communities water management technology ideals. We look forward to the long term results of this project.

Metropolitan housed the simplex pump system in a clamshell structure for convenience.

Metropolitan housed the simplex pump system in a clamshell structure for convenience.

At Metropolitan Industries, we take great pride in our ability to design retrofit solutions to meet your needs.  Our engineering expertise and dedicated sales and service staffs can design custom solutions best suited to solve your water and wastewater challenges.

As case study illustrating our dedication to being problem solvers can be demonstrated by the work done in a village located in DuPage County, Ill.   At the request of the owner, the location of the project will remain confidential.

“The customer needed to deliver water pressure to a small housed concession stand located at an outdoor sports complex,” said Metropolitan commercial sales manager Mike Ponx.  “They required a simplex system housed in compact fashion, so we contained the system in a small clamshell structure.  With this solution, the final product isn’t an eye-catcher and still delivers the water pressure needed for the concession stand to function properly.”

Ponx said the system needed to provide enough water pressure to deliver flow to sinks, lavatories, water closets and hoses within the concession stand.  In order to accommodate, Metropolitan supplied a simplex system with a designed flow rate of 59 GPM at a discharge pressure of 90 PSI.

Ponx said the application of the clamshell structure was ideal for the customer due to its cost-effective price.

“From a financial standpoint, this made the most sense for the customer because they did not have the space or housing already in place for the system,” said Ponx.  “An alternative solution, such as a prefabricated housed structure, would have been much more costly.”

Ponx said a number of amenities were included within the housed structure to ensure routine maintenance and checkup would be hassle-free.

“We included a heating system and a drop light for times when service is being conducted,” said Ponx.  “The structure itself comes with a large enough power supply to run not only the pump, but an electric heater as well.  It also runs a convenience outlet that provides the customer with power when needed.  Everything was supplied as a prefabricated packaged system.”

Overall, Ponx said the project depicts Metropolitan’s vast and unique capabilities, particularly within its commercial division.

“This project demonstrates how diverse we are and our ability to solve problems, small or large,” said Ponx.  “Our commercial division has the ability to service high-rise buildings or, in this case, small structures that do not require very large systems.  In any case, we can provide customers with a number of options and custom solutions applicable to their needs.”

To supply the desired cooling water to the facility, Metropolitan provided a customized triplex booster pump system.

One of the primary aspects of our company that makes Metropolitan Industries an ideal partner for business is our dedicated design and service staffs. No matter how complex your job may be, Metropolitan is determined to meet your needs and requirements. At times we are faced with projects in which strict specifications must be followed. We take customer specifications with great seriousness and can customize projects to meet important guidelines.

A premier example of our ability to provide customized solutions can be illustrated by the work done at a large municipal water treatment facility that conducts o-zone generation.

Metropolitan was first contacted by Symbiont Science, Engineering & Construction, Inc. in 2011 to provide a Metro-Varipac triplex booster pump system to supply cooling water to the facility. The existing pressure boosting system the customer had been using ran at a constant speed. Metropolitan implemented the triplex system with a design point of 300 GPM at 185.5 feet of TDH to become the primary system. The system runs at a maximum of 425 GPM at 120 feet of TDH, and each pump is rated at a minimum of 25 HP. A 200 PSI rated hydropnuematic pressure tank was also included.

Project specifications called for custom programming.

“One of the unique aspects of Metropolitan is our ability to provide both standard and custom programmed controls,” said Metropolitan salesperson Tim Laskowski. “This particular project was very job and system specific, but we were able to supply everything the customer needed.”

Metropolitan was also able to provide the customer with a specialized startup and certified test of the system on-site. A flow meter and all certified pressure gauges were included to meet project specifications and Hydraulic Institute standards.

Metropolitan’s Paul Larson, P.E., said stainless steel features were added to the system to provide corrosion resistance.

“We integrated a stainless steel skid, stainless steel control panel and galvanized piping which will prevent corrosion, and thus extend the life of the system,” said Larson.

Stainless steel features were added as a customized element to the system.

The system also came complete with variable frequency drives, eliminating the constant speed control the previous system had utilized. Variable speed controls can save customers thousands in energy savings and eliminate the need for pressure reducing valves.

“Metropolitan is completely dedicated to providing energy efficient products to our customers,” said Laskowski. “We can design systems to pump at the lowest possible pressure, which saves in energy costs and can even pay for an entire system with savings accumulated over time.”

Project engineer Pat Carnahan of Symbiont said Metropolitan’s ability to test a system on-site was a nice change of pace when working on this type of project.

“It was a welcomed experienced to work with a vendor with skilled people who can think on their feet,” said Carnahan. “The test went very well and we were able to verify the majority of the control features during one day of testing.”

Carnahan also noted that Symbiont was pleased to find that the pump skid was constructed and delivered to their precise layout and control requirements.

“In the past we’ve purchased pump skid systems and our specified control sequences were not provided,” said Carnahan. “A level of comfort was established with Metropolitan on this project because the system supplied matched our specifications and expectations.”

Part of Metropolitan’s commitment to customer service is sharing our expertise with customers, operators and engineers. Metropolitan provided on-site training for the customer to ensure the transition from the previous system to the new system was proficient and easy.

Overall, Laskowski said the project demonstrates Metropolitan’s flexibility and dedication to providing customers with projects that match precise requirements.

“This job illustrates how we’re able to handle whatever comes at us and get the job done correctly,” said Laskowski. “We take the specifications seriously and we’re very careful in supplying exactly what the customer has asked for at a very competitive price.”
