New Load Sharing U.S. Patent Announcement

Various examples of our patented load sharing technology being used in complex pumping situations.

Various examples of our patented load sharing technology being used in complex pumping situations.

 
Metropolitan Industries Inc. is proud to announce that the company has been issued a system and method patent by the U. S. Patent Office (No. US 8,180,496 B2) which will allow dissimilar variable speed pumps to be controlled in a way never before possible. We have elected to market our programmable logic control systems utilizing this technology by using the term “load sharing.”

The development of load sharing should be very welcome news to anyone attempting to operate any liquid transfer or pressurization system through the use of dissimilar pumps or other challenging hydraulic scenarios. The load sharing process allows Metropolitan to manufacture specialized variable speed control systems for pumping applications which have multiple dissimilar pumps or pumps which need to operate together under varying hydraulic conditions.

Load sharing will eliminate conditions during which one or more pumps operate under high or extremely high energy load conditions, while other pumps within the system are extremely under loaded electrically. These operating conditions are undesirable because they typically cause the pumps to operate well outside of their zone of peak hydraulic efficiency. Load sharing, in essence, is a way of ensuring that all dissimilar pumps within a system tend to operate at peak hydraulic efficiency, regardless of the hydraulic load of the process they are feeding, the hydraulic conditions under which they are operating, and the varying load profile of each pump.

Load sharing defined:

Load sharing is a dynamically-equalizing process by which two or more dissimilar pumps, with dissimilar hydraulic characteristics or operating under dissimilar hydraulic conditions, are operated in unison to accomplish a common task, while drawing a commonality of electrical energy proportional to their individual load characteristics. The process is dynamic because the electrical power load of each pump on the system is continuously compared to the maximum load of the unit. In addition, the electrical power load of each individual pump is also continuously adjusted in proportion to each of the other units, so that the percent load of each unit is proportionally matched by all other units. As such, each of the pumps on the system will very likely operate at rotating speeds which differ from one unit to the next, while attaining the exact same desired set point task.

Common task clarified:

The grouping of pumps must be programmed to accomplish the same set point task, whether the task is to maintain a common line pressure, maintain a common outlet temperature, maintain a common pumped water elevation or, in some instances, a combination of two of these tasks.

Commonality of proportional energy explored:

The load sharing program will adjust the speed of each pump individually while maintaining the common task set point(s), so that the power load (or kilowatt consumption) of each pump in the group is proportional to the load of all pumps in the group.

Example scenario: One 20 HP pump will operate at 10 BHP, while two 60 HP pumps each operate at 30 BHP. In this scenario, each pump in the system operates at 50 percent of its peak load. This process dynamically and continuously varies proportionally, as the demands of the pumped process changes.

Real world examples:

The load sharing process we’ve patented is designed to be very flexible, allowing the technology to be adapted to a variety of applications. The technology will provide us with the unique ability to tackle some of the most challenging hydraulic scenarios in the markets and industries we serve.

Our load sharing program being used in a commercial building application.

 
Multiple pumps with dissimilar flow capabilities:

One or more smaller jockey pumps (or lead pumps) can operate with one or more larger duty pumps (or lag pumps). Possible examples would be a water pressure booster system for a large commercial building or, potentially, a municipal water pumping station. Pumps of various rated flows can work together, each with a shared proportion of their rated horsepower.

Multiple pumps with dissimilar performance characteristics:

One or more pumps with “steep” curve characteristics can operate with one or more pumps with “flat” curve characteristics. This is the perfect process control in a scenario where one or more multi-stage pumps need to operate in conjunction with one or more single-stage pumps.

Multiple pumps, at different geographic locations, feeding a common process:

A municipal pumping station at the east end of town can operate in unison with another pump station at the west end of town. Load sharing is a great solution, especially if the pump stations are at different elevations. Managing this type of application is also enhanced if the water main friction loss profiles are also very different at each end of town.

Multiple pumps, with different suction pressures, feeding a common process:

An exceptionally difficult process-control scenario can be overcome with relative ease. A municipal pumping application, including two or more gravity tanks at varying elevations, feeding a multiple pump system, with a single set point pressure, is an excellent application for load sharing technology.

Multiple pumps with dissimilar motor sizes:

By the nature of the pumps described, many of the scenarios mentioned above will inherently include pumps with various motor sizes. Load sharing will allow all of these systems to operate at their proportionally equal power load, which in itself will tend to ensure operation within the peak efficiency range of their individual performance curves.

Make no mistake: This process program is extremely unique and will be a very valuable asset to our clients while operating their most challenging pumping applications.

Metropolitan provides local village with a boost

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.”

Florida municipality upgrades to housed pump system

Metropolitan supplied the municipality with a prefabricated housed system, including all associated pumps, piping and controls.

 
At Metropolitan Industries, our reach extends far beyond the Midwest. Our national sales team can supply customized pumping solutions shipped fully assembled for ease of installation. Over the years, we have provided domestic water booster systems, complete sump and sewage lift station packages and many more of our cataloged products to customers not just nationwide, but around the globe as well.

Our ability to deliver solutions to pumping challenges to all is demonstrated by the work done in the city of Marianna, Fla. Working with an existing pump system over 25 years old and in need of more pumping capacity, the city turned to the team of Blankenship Contracting, Inc., Pump and Process Equipment Company and Metropolitan Industries to provide a custom solution.

“The customer required a custom pump system package that would not only provide more flow to account for increased demand, but could also supply the fire flow if needed,” said Pump and Process Equipment’s Eric McGee. “To meet these specifications, we designed a three-pump system housed in a prefabricated steel building, all of which was supplied by Metropolitan.”

Each of the three pumps is designed to provide a flow of 750 GPM at 134 feet of TDH. Each pump motor is rated at 40 HP and performs at 3500 RPM at 76.6 percent efficiency.

The prefabricated galvanized steel building includes a 72-inch by 84-inch double door entry to the pump room and a “pebblestone” exterior finish for an attractive design solution.

The system will primarily serve a nearby health department and surrounding residents.

McGee said initial design discussions planned to incorporate a two-pump system, but after discussing options with Metropolitan salesperson Mike Tierney, the group came to a resolution to implement a three-pump system housed in a prefabricated structure.

“We originally planned to build a system with two large pumps, but instead, designed a system with three smaller pumps for a variety of reasons, one of them being energy-efficient operation,” said McGee. “With three pumps, we can run just one at low loads. If the demand increases at any time, the other pump(s) will kick into gear.”

McGee said one of the primary challenges faced was meeting a short lead time, which forced the team of Metropolitan, Pump and Process and Blankenship to complete the project in a quick and well-organized fashion.

“From start to finish, we only had around 8 to 10 weeks to complete the project,” said McGee. “It required a team effort from everyone involved and thanks to a well-executed plan, we were able to deliver the system to our customer on time.”

In order to ensure water operators were familiar with the new system, Metropolitan sent service technicians to the job site to conduct training.

“Training provides a good start for customers when becoming acclimated to a new system,” said McGee. “Knowing the major do’s and don’ts of a system can make for a smooth transition.”

McGee said working with a single source provider was critical to Pump and Process and a chief reason why Metropolitan was involved with the project.

“We wanted to partner with an organization that had all capabilities under one roof,” said McGee. “Metropolitan was able to provide manufacturing, controls, pumps and service. We were comfortable having to contact one sole organization if any issues arose.”

Since installation, McGee said the system has run “flawlessly” and described his overall experience of working with Metropolitan as positive.

“When working with Metropolitan, the word professionalism comes to mind,” said McGee. “We’ve worked with many businesses in the water and wastewater industries and appreciate the way Metropolitan communicates with its customers. The ‘no excuses’ approach they take to developing a system ensures quality is of supreme concern.”

Nicor Rebate Program helping businesses save

From left to right: DRF’s Scott Schnurr, Dominican University president Donna M. Carroll, and Nicor Gas president Beth Reese pose with the check Dominican University received through participating in the Nicor Gas Business Custom Incentive Program.

 
Through participating in the Nicor Gas Energy Efficiency Program, Dominican University was given the opportunity to upgrade existing heating equipment in its facilities, and save significantly in the process.

Developed to offer large businesses the opportunities to improve the energy efficiency of their facilities and save money, Dominican participated in the Nicor Gas Business Custom Incentive Program, which provides financial incentives for the installation of high-efficiency equipment not covered by the Nicor Gas Energy Efficiency Program’s Business Rebate Program. Through the program, businesses can receive up to $500,000 on their gas-savings projects per year.

According to Nicor, incentives are paid based on energy savings beyond baseline energy performances, such as state or federal codes and standards, industry-accepted performance standards, or other baseline energy performance standards as determined by the Nicor Business Custom Incentive Program.

The current cycle of the program is available for projects installed from June 1, 2012 through May 31, 2014, or until funds are depleted. Per Nicor requirements, post-installation inspections must be conducted and final applications must be submitted to the program by June 30, 2014. Businesses seeking to participate in the program must attain pre-approval in order to become eligible.

Detailed information regarding the program can be found in the Nicor Gas Business Custom Incentive Program handbook.

Dominican began working with DRF Trusted Property Solutions of Plainfield, Ill. in 2010 when DRF observed a large amount of gas being used during the summer months. After developing an initial project design that did not qualify for the Nicor Gas Business Custom Incentive Program, nor provide the desired financial benefits, DRF turned to Metropolitan Industries to help provide a custom solution.

The final project design included three individual point of use systems customized to handle specified heating demands.

Metropolitan HVAC salesperson Matt Brickey praised the program’s ability to assist businesses seeking to conduct retro-fit upgrades progress in an expedited fashion.

“In the case of Dominican University, this program not only helped cover some of the costs of the custom equipment and installation, the gas savings realized will continue to give back for years to come,” said Brickey. “Because of the financial benefits the rebate program offers, it can help prospective customers who may be facing budget constraints get projects moving in the right direction.”

For complete information regarding this project, please visit The Chief Engineer, which profiled the project in its December issue.

For information regarding our custom HVAC solutions and how you may be eligible to save through the Nicor Gas Business Custom Incentive Program, please contact a Metropolitan representative at (800) 323-1665 or visit www.metropolitanind.com.

Metropolitan tackles confined space dangers

Entering a confined space for system repair is a dangerous procedure, particularly due to accumulated gases that may be hazardous. At Metropolitan, we can provide solutions to decrease the frequency of entering a confined space.

 
Now more than ever, municipalities are addressing the dangers of below ground pump stations to protect both entrants into confined spaces and the investment of systems themselves. The United States Department of Labor requires a permit for those seeking to enter confined spaces for system repair, accompanied by rigorous guidelines those involved with the entry must follow.

Moreover, flooding of below ground pump systems can lead to catastrophic damage of the systems themselves, often costing municipalities a great deal for repair or even replacement, and can lead to an emergency service call.

Metropolitan Industries recently renovated three below ground pump stations, giving each customer the ability to interface with the controls without entering the confined space. Another advantage of “above grade controls” is the avoidance of control system damage caused by a vault flood. Potential future projects such as submersible pump retro-fit into the existing wet well would be the next appropriate step to completely eliminate confined space entry.

City of Calumet City, Ill.

The City of Calumet City, Ill. recently came to Metropolitan for an emergency rehabilitation project following the flooding of a below ground water pump station.

“Metropolitan suspects the reservoir fill valve stuck open causing an overflow condition, thus filling the below ground pump station with water,” said Metropolitan salesperson Keith Girup. “The existing booster station was constructed many years ago when below ground systems were common. Metropolitan was able to repair and replace equipment quickly, and in the process improve the operation and energy-efficiency of the station by implementing variable frequency drives for constant pressure control.”

Another new piece of equipment included in the upgrade was a low-flow shutdown bladder storage tank.

“The new bladder tank supports the water system leak loads during low flow periods of time,” Girup said.

The system was also integrated into a city-wide SCADA system for enhanced monitoring and alarm notification. A flood switch was added to the pump room to ensure notification is provided in the event of a flood since the pumps remain in the below ground vault and are subjected to the hazards associated with such a location.

The primary advantages of the system upgrades are the reduced frequency of entering a confined space and overall protection of the equipment.

South Palos Sanitary District

Metropolitan recently completed a similar project for the South Palos Sanitary District.

“In this project, the customer decided to keep their drywell pumps below ground, but implemented above grade controls into a new prefabricated concrete building with an exposed aggregate finish,” said Girup. “The prefabricated building contains the controls, generator and a temperature control device, essentially eliminating the need to enter below ground in order to interface with the controls.”

Girup said that because the customer has decided to keep the drywell pumps below ground, it will still be necessary to go below ground to maintain the pumps. However, the frequency of confined space entry has decreased dramatically with the implementation of above ground controls.

“Safety and common sense are the reasons for upgrading to above grade systems,” said Girup. “Going into a confined space requires special procedures with two individuals, safety harnesses and gas monitoring equipment at a minimum to ensure safety. If precautions are not followed, consequences could be fatal.”

Village of Burr Ridge, Ill.

The Village of Burr Ridge, Ill. also called upon Metropolitan for a below ground lift station upgrade.

Metropolitan implemented an above ground traffic box for this particular project, placing all controls and electrical distribution equipment above ground.

“The customer has intentions to replace the existing pumps with submersible pumps, however, this project was phase one, which included the above grade controls to significantly reduce the amount of times they would need to go below ground,” said Girup. “In the previous configuration, the customer was going down into the pit quite often to monitor controls, but with our upgrade, they no longer have to do so.”

Conclusion

With each upgrade, the customer not only gained capital investment protection by implementing above grade control systems to protect controls from potential below ground flooding, they also improved safety conditions by reducing the frequency of confined space entry.

Entering a confined space is a major process with strict guidelines which, if not followed, can produce fatal consequences. Metropolitan can provide both investment protection and overall safety with above ground system retro-fit solutions.

MetroMail™ monitoring system included in recent lift station retrofit

MetroMail™ is an economical option for customers seeking basic monitoring equipment.

Metropolitan Industries recently completed a stand-alone version of MetroMail™, the company’s very own alarm notification system. The company will receive alarm notification via text message and/ or email through the internet.

When implemented to monitor any pump or electrical system, MetroMail™ has the capability to send email alerts to notify users of equipment status or problems, and can assist customers in avoiding potential disaster when troubles arise.

“Users can configure MetroMail™ to send an email at an interval completely configurable by users out through the device’s Ethernet jack and through the Internet,” said Metropolitan Industries software engineer Joe Burza. “In other words, if you have your laptop on you or you’re carrying a device with email capability, you can receive a message that a problem with your pump has occurred instead of waiting for the water to back up and start flooding.”

MetroMail™ features eight optically isolated dry inputs accepting 10 to 30 volts of AC or DC power. The unit’s status light tells users whether the unit has power, is properly configured and is sending emails, whereas network lights indicate LAN activity and connectivity. Its onboard web server allows for the configuration of messages, addresses and other settings via any web browser.

A MetroMail™ unit was recently installed at a jail located in northwest Indiana. Metropolitan was contacted by Keough Mechanical for the project, who wished to upgrade the existing lift station due to clogged pumps reported by detention center officials.

The lift station in need of attention was responsible for all of the sanitary waste from the facility. Detained members knew of its function and would routinely disrupt the operation of the pump system by flushing items that would typically be disposed of in a garbage can.

After Metropolitan salesperson Keith Girup made a field visit with the owner and contractor to discuss the problem with the operators and evaluate the obstacles associated with the retrofit upgrade, it was determined that an impeller change would be the most suitable solution to significantly reduce and potentially eliminate the clogging issues.

While Metropolitan was helping solve the mechanical issues the facility faced, new controls with email notification were also proposed.

In order to provide this notification, Metropolitan included MetroMail™, which contacts personnel by email in the event of a lift station alarm condition. An operator interface with Internet connectivity via a cellular modem was also included.

These control features allow for quick response during an alarm condition with 24-hour supervisory ability.

MetroMail™ offers customers a cost-effective option for basic monitoring equipment when more expensive options are not practical. Its convenient size also gives customers the flexibility to monitor equipment when space is a concern.

For more information regarding MetroMail™, please contact Keith Girup at 800-323-1665, ext. 264 or sales@metropolitanind.com.

Local municipality completes major lift station renovation

With the help of Metropolitan Industries, the Village of Romeoville, Ill. implemented major upgrades to its O’Hara Woods lift station.

 
Metropolitan Industries has extensive experience in the implementation and upgrade of lift stations. For over 50 years, we have provided components and even complete prefabricated lift stations as single-source systems that include all equipment required for operation.

Services such as design assistance and a 24/7 service department help ensure systems are engineered to meet the owner’s specifications in a variety of sizes. For the complete system, a station can be combined with a “MetroFab” custom-designed, prefabricated housed system. Housed systems are factory pre-piped and wired, and are shipped fully assembled for easy installation. Like a prefabricated lift station, these systems can also be customized to meet any specifications you require.

A recent example of a customer’s desire for a significant upgrade to their existing facilities is the work completed at the Romeoville, Ill. O’Hara Woods lift station.

Working with an existing duplex sanitary lift station, the village decided to make many custom upgrades to the site.

“The existing 20-year-old duplex system was still functioning fine, but an upgrade was needed due to village growth and the planning for future development,” said Metropolitan salesperson Keith Girup. “To keep up with the demand, the station was upgraded to a triplex system by utilizing the existing duplex wet well and a parallel existing manhole for a simplex wet well to house the three new pumps. We also supplied three precast concrete enclosures which, when installed on the concrete pad, were made to look like one common building. The three separate rooms make up the building, and house the new lift station controls, standby generator and chemical dosing system all under a common 28-foot by 28-foot roof.”

The previous configuration did not feature enough pumping capacity to keep up with the station’s increased demand.

 
In total, the system now has three eight-inch submersible, non-clog, explosion-proof sewage pumps each with a capacity of 2,084 GPM at 99 feet of TDH. Each pump motor is rated at 125 HP, 1750 RPM, 60 Hz, 480 volt, three-phase.

Control system upgrades were made to replace obsolete equipment not capable of operating the new horsepower and new quantity of pumps. In addition, the prefabricated concrete buildings gave the customer a more secure and attractive solution. Metropolitan supplied the three prefabricated buildings and provided a simulated “Ashlar Stone” finish as an attractive exterior design. Inside walls are painted concrete and the owner chose an aesthetically pleasing metal roof to complete the buildings.

In addition to housing the new controls, another primary benefit of the lift station upgrade was the addition of new variable frequency drives.

“All pumps are variable speed meaning they will speed up or slow down to match the influent rate,” said Girup. “This type of application only uses electrical consumption as needed, thus saving energy.”

Another upgrade included in-place standby power.

“When power loss would occur in the previous configuration, the customer needed to mobilize personnel and a portable generator unit to support the remote lift station,” said Girup. “In the new configuration, the permanent standby 400 kW, diesel-fueled generator will support all three pumps during a power failure automatically.”

An additional advantage of including a permanent generator is phase protection. If any phase of power is dropped at any time, the generator’s automatic transfer switch will recognize the power failure and supply clean power from the generator to the pumps until the full power supply is regained. Because pump motors may burn up during dropped phases, or brown outs, the permanent generator provides further investment protection to the lift station.

In addition to the standby generator, a chemical dosing system was supplied to replace the existing system. The new chemical system provides accurate feeding of treatment chemicals via a dosing pump that paces the total sewage discharge flow rate and reduces the frequency of chemical replenishment by increasing the volume of the storage tank, thus reducing fees associated with chemical delivery. The implementation of a chemical tank was deemed necessary per customer specifications. The chemical is used for odor control and to start the biological process of the sewage, assisting in the treatment process.

Surveillance cameras and anti-graffiti coating were also part of the new control and SCADA system upgrades.

New equipment was needed to monitor flow and tie in the third pump. A polyurea-coated, prefabricated meter and valve vault with measurements of 16 feet in length and 8 feet in diameter was also included to connect the new simplex pump system with the existing duplex system and also includes flood-proof hatches. Flood-proof hatches were provided due to the fact the lift station is located directly next to a large pond. The hatch elevations now all exceed the 100-year flood event elevation, however, if the customer does encounter significant rainfall, the hatches are water tight and will not allow water into the wet well, valve vault or meter vault.

A number of accommodations were made for the customer while upgrades were taking place, the most important being the need to keep the station functioning during construction.

Among the many upgrades provided to the O’Hara Woods lift station was the addition of new controls.

 
“A great deal of planning was done ahead of time to make the field installation, start-up and integration into the SCADA system seamless,” said Girup. “All of the buildings were pre-wired and all controls were programmed before arrival on-site, making the transition as efficient as possible. The prefabricated components of the project allowed the contractor to save on bypass pumping due to the expedited nature of prefabricated system installation.”

An existing control enclosure also needed to be moved to a strategic location for installation to occur simultaneously with the existing lift station still in service. The existing control box was located close to where the prefabricated buildings would be installed. The contractor and supplier made sure the entire transplant of controls remained reliable and the customer did not miss a beat in regards to system operation, data acquisition and potential alarm notification.

“The prefabricated buildings were chosen for a variety of reasons, including cost and security,” said Girup. “Alternatives such as a large steel traffic box enclosure would have been nearly as costly, but would not have provided the same level of security that the buildings provide.”

The project reflects Metropolitan’s commitment and ability to meet the customer’s needs with ease of installation and peace of mind while making a smooth transition to an upgraded system.

A large upgrade project such as the Romeoville O’Hara Woods job is a large undertaking for all involved not only financially, but in regards to keeping the existing system in operation while upgrades are taking place. Metropolitan’s expertise, customer service and fabrication abilities helped to ensure the best possible transition from the old existing system to a first class facility.

The new improvements include a total of three sewage pumps, and provide housing along with surveillance cameras and anti-graffiti coating for further protection.

 
Project engineer, Jon Zabrocki, P.E., of Robinson Engineering, LTD praised Metropolitan’s ability to supply and support all of the equipment needed for this installation.

“When you’re dealing with a project as complex as this, it’s comforting to know you’re working with a single-source provider who is willing to take on the responsibility of supplying and supporting anything you might need throughout the job,” said Zabrocki. “The end result is that the new system has exceeded our expectations and it shows what can be done when owner, contractor, supplier and engineer are all on the same page.”

Village of Romeoville, Ill. wastewater superintendent Bob Stoppenbach credited the village’s confidence in all parties involved for establishing a strong level of comfort throughout the entire rehabilitation process.

“We’ve worked with Metropolitan on many projects and knew they were very capable of delivering the quality of upgrades that we required,” said Stoppenbach. “We were very pleased at the project’s conclusion and look forward to working with them again in the future.”

Housed pump systems provide cost-friendly solution for municipality

One of two prefabricated housed booster systems supplied to the Village of Park Forest, Ill.

 
Metropolitan Industries recently supplied two prefabricated housed booster systems, along with components for a third system, to the Village of Park Forest, Ill.

The project was funded by a state grant and the station in need of repair was the village’s lime softening water treatment plant, which had been designed in the 1930s.  The village was experiencing main water breaks close to the treatment plant and called upon Baxter & Woodman Consulting Engineers to help develop a solution.  Working with Metropolitan, Baxter & Woodman determined the implementation of two prefabricated housed systems, and components for a future third system, would remedy the problem at a cost-efficient price.

“With the existing configuration the village was working with, it wasn’t able to generate the 70 pounds of pressure it needed to fill its elevated tanks,” said Metropolitan salesperson Keith Girup.  “By providing our booster systems at the elevated tanks, it was able to dial the treatment plant back to around 50 pounds of pressure to reduce the risk of experiencing more main water breaks.  Each of our booster systems provides the extra 20 pounds needed to fill the elevated tanks.”

Girup said that while these fixtures are ideally temporary solutions, they’ve eliminated the need for the village to make a very expensive purchase it may have not been able to finance.

“Ideally, this should be a temporary solution because water mains that are in dire shape like the ones in this particular system need to eventually be replaced,” said Girup.  “However, that could be a very expensive venture and the customer decided it was financially practical to purchase more costly efficient boosters and finance the very expensive project over time.  In some cases, additionally booster stations aren’t necessarily a positive, but here, they were the practical answer.”

Indiana high school makes significant upgrades to pump system

The new pump station was designed for ease of installation and a proficient transition from old system to new system.

 
When Arsenal Technical High School made the de­cision to upgrade an old submersible dry pit pump system, the Indianapolis, Ind.-based institution called upon Metropolitan Industries to renew its system through both effective and convenient means.

“Metropolitan built a triplex self-priming pump system that closed in a house and contained a gener­ator inside,” said national salesperson Tim Laskows­ki. “The packaged unit essentially sits on top of the existing wet well, which made the installation process very efficient.  All in all, the transition from the existing system to the new system was very convenient for the customer.”

Metropolitan removed the existing pumps that were no longer in function, left the wet well where waste collects, dropped the suction lines for the self-prim­ing pumps, and packaged it all up in one convenient unit.

The system, which is designed to collect sewage and transport it to the appropriate destination, start­ed out as a very small project that eventually turned large, incorporating a prefabricated steel building.

It total, Metropolitan supplied a complete station with pumps, motors, valves, fittings, wiring support bases and incidentals with the prefab­ricated steel building, which includes a simulated brick finish as an attractive design solution.  A total of three pumps, each with a TDH of 33 feet and a capacity of 500 GPM were supplied. An 80 kW generator was also included with the package.

Metropolitan manufactured the entire system on-site and shipped ready for installation.

 
One of the differences between this particular unit and alternative solutions for enclosed structures was the implementation of the imitation brick, which was chosen to match the surrounding campus of Arsenal Tech.

“The material we used was very thin, almost like sheets of plywood, and was routed to look like brick,” said Laskowski. “It provided a very nice design solution and complemented its surroundings very nicely.”

Laskowski said the construction of the program went smoothly and that the customer was ultimate­ly satisfied at the project’s conclusion.

“We actually had the engineers who specified the product at our facility in Romeoville, Ill.,” said Laskowski. “They were able to witness the construction process firsthand were very impressed by our work. We delivered and installed the new system without any problems.”

For more information please contact Tim Laskowski at 815-886-9200, ext. 255 or sales@metropolitanind.com.
