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.”

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.”

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.”

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™ 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 dialing” system.

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.
