Lift Station Case Studies

Village of Chicago Ridge, Ill. Adds New Lift Station Controls
Confined space entry presents significant hazards to municipalities working with below ground pump stations.
The flooding of below grade stations can lead to an emergency service call and cause catastrophic damage of system equipment, often costing owners greatly for expedited repair or even replacement.
More importantly, confined spaces present health threats to entrants. Atmospheric conditions such as lack of oxygen, dense gases and additional dangers force operators to follow stringent guidelines when entering confined spaces to ensure adverse health consequences are avoided.
Above Ground Lift Station, Traffic Box

Faced with a flooded below ground pump station, the village of Chicago Ridge, Ill. looked to Metropolitan Industries for an emergency solution.

At Metropolitan, we believe upgrading below ground pump stations with above grade solutions most effectively protects both the investment of systems and the lives of equipment operators.
While eliminating confined space entry entirely should be the end goal, our above grade solutions can significantly reduce the frequency workers must enter confined spaces. With a comprehensive submersible pump retrofit, the need to enter confined spaces can be completely eliminated.
An illustration of our ability to retrofit below ground pump stations can be demonstrated by the work done in the village of Chicago Ridge, Ill. Faced with severely damaged system equipment, including pumps and controls due to a below ground vault flood, the village turned to Metropolitan to provide a quick solution.
“During a heavy rain event, a sump pump situated in the pump station’s dry pit malfunctioned allowing sewage to flow from the wet well to the dry well, causing the dry well to flood,” said Metropolitan municipal salesperson Keith Girup. “Unfortunately, due to the dry well flooding, the customer’s investment, including pumps, controls and power distribution equipment, was completely submerged underwater and caused irreparable damage. An immediate emergency retrofit solution was required.”
In order to get the pump station up and running in an accelerated fashion, the village elected to bake dry the pump motors, which were eventually placed back into the below ground station. To reduce the occurrence of entering the below ground confined space and protect the investment of system controls, Metropolitan supplied the village with an above grade control traffic box.
Included with the traffic box package was Metropolitan’s new LMS II level management system. Completely off the shelf and designed to provide customers with vital SCADA features at a cost-effective price, the LMS II control package played a key role in supplying the village with a prompt solution.

Metropolitan’s new LMS II level management system contains a standard program to cover nearly all lift station applications.

Developed by Metropolitan’s research and development team, the LMS II is a menu-configurable, constant speed pump down level controller, allowing one to three pumps, single/dual level transducers, 0-20 mA flow meter input, and a completely redundant float backup controller. Seal fails and thermal inputs are available by default.
The LMS II can be accessed directly at a lift station on its easy-to-use color touch screen interface or controlled remotely via a laptop. With the inclusion of an internet connection or cell modem, and Metropolitan’s MetroMail™ alarm-dialing system, users can receive alarm notification via any SMS text or email compatible device.
“In developing the LMS II, our goal was to create a standard program with options that covered 90 percent of all lift station applications,” said Metropolitan research and development manager Wayne Barkley. “This program gives us a systematic solution to designing lift station controls, eliminating much of the excessive labor associated with the design, engineering and programming of controls. Right out of the box, this system can serve many stormwater and sanitary stations with one program.”
Girup said the LMS II can fit a variety of lift station uses and is especially advantageous for consumers who seek to one day implement a master SCADA or building automation system. The LMS II is can also be used in commercial applications. “Each LMS II unit can be defined as a distributed SCADA system, providing substantial benefits to owners who may have plans to one day build a centralized SCADA system with master computer,” said Girup. “The LMS II has the capability to communicate with owners via email and/or text message, and can also be viewed via the internet for current system information, as well as historical data trends. The LMS II allows for a phased distributed SCADA approach, which can ultimately be tied into a more sophisticated centralized SCADA system at a future date.”
In addition to the traffic box package, Metropolitan also included a flood switch for installation into the dry well to notify operators via their SCADA system in the event of another dry well flood. This allows for a rapid response in the effort to prevent further flooding of the pump station’s dry pit.

Due to a below ground vault flood, the pump station’s vital equipment, including pumps and controls, sustained significant damage.

Girup said this project is likely to serve as phase one of an extensive retrofit of the entire pump station. Phase two would be the installation of submersible pumps into the existing wet well, which would allow for the complete elimination of the confined space.
“Metropolitan is typically able to provide customers with an à la carte solution,” said Girup. “When the resources to fund a complete retrofit upgrade of a pump station are not feasible, we have the ability to work with the customer’s budget to supply the equipment and services that are most practical for the owner and application at a given time.”
This, combined with our 24/7/365 emergency service assistance, led to the successful, expedited upgrade solution for the village of Chicago Ridge.
“This project is a perfect example of why municipalities should start budgeting to upgrade existing dry pit pump stations of this type,” said Girup. “Fortunately, we were able to respond to the customer very quickly. In the coming years, I anticipate that many municipalities will continue to call on Metropolitan for a phased retrofit upgrade solution to eliminate confined space, below ground pump stations in the effort to avoid emergency circumstances.”

Village of Hoffman Estates, Ill. Upgrades Lift Station
Working with a below ground pump system and faced with the dangers associated with entering a confined space, the village of Hoffman Estates, Ill. turned to the trio of Metropolitan Industries, Inc., of Romeoville, Ill., engineer Burns & McDonnell of Chicago, Ill. and Bolder Contractors, Inc. of Deerfield, Ill. to deliver an above ground solution.
“The previous system the village employed was a below ground pump station which required operators to enter a confined space when the need to conduct service was presented,” said Metropolitan salesperson Ken Turnquist. “Our design team not only supplied three brand new submersible pumps, we also provided new controls consisting of a control panel with a color operator interface, SCADA panel, flow meter converter, submersible transducer and three 100 HP variable frequency drives. All controls were housed in a large stainless steel mounted traffic box.”
Above Ground Lift Station, Traffic Box

A large stainless steel traffic box housing all controls and a permanent standby generator were part of the supplied package.

Each of the three pumps has a pumping capacity of 1900 GPM at 100 feet of TDH and four-inch diameter solids handling capability. Each pump motor is rated at 100 HP, 1750 RPM, 460 volt, three-phase and 60 Hz.
Installation included the addition of a new valve vault and the reuse of an existing oval-shaped wet well to accept the new triplex system. A permanent standby 250 kW diesel-fueled generator was also included with the package. The generator’s 600 amp automatic transfer switch was placed in the traffic box.
Additional accessories included a 48-inch by 108-inch safety grate hatch for wet well access and a 36-inch by 64-inch safety grate hatch for valve vault access.
Turnquist said the above ground traffic box provides the village with a safer method of interfacing with controls. “Confined spaces present serious dangers for those who need enter below ground confined spaces to service pumps, interact with controls and more,” said Turnquist. “If safety precautions are not followed with great care, consequences could be serious. The implementation of above ground controls significantly reduces the frequency water operators will need to enter a confined space.”
Wet Well Valve Vault Safety

To ensure safety, access hatches were added for entrance into the wet well and valve vault.

An additional advantage of above ground controls is investment protection.
“Having controls below ground opens the door to potential system damage with the danger of vault floods,” said Turnquist. “Placing controls above ground eliminates the hazards associated with placing them below ground and ultimately improves the longevity of equipment.”
Turnquist said the variable frequency drives, which slow down or speed up pumps, can possibly offer a reduction in energy costs.
Controls were specified by engineer Burns & McDonnell and supplied by Metropolitan Industries. Metropolitan also supplied the traffic box complete with all controls, which was transported to the village in two parts and eventually combined into one onsite.
“Because of the nature of the specified controls, we needed to construct a double, back-to-back traffic box,” said Turnquist. “It was one of the largest Metropolitan has ever provided and Bolder Contractors Inc. did a great job ensuring its delivery and installation was well-organized.”

Village of Bedford Park, Ill Eliminates Confined Space For Good
Metropolitan Industries recently completed two lift station systems for the Village of Bedford Park, Ill., that eliminated existing confined space procedures that were a liability issue for village employees and a strain on the public works budget.
Lift Station Installation

Separate storm and sanitary lift stations installed with a control building and generator eliminated existing confined space installations.

The Village of Bedford Park is located on the southwestern border of Chicago city limits. The village is near Chicago’s Midway Airport and is minutes from downtown Chicago. It is part of an Illinois enterprise zone, and is an integral partner of the Illinois and Michigan Heritage Canal Corridor.
As part of a significant public works upgrade, the village board approved the removal of an existing sanitary lift station and a storm water lift station that required strict adherence to confined space application protocol when a worker entered the basin to perform service.
Confined space installations were common many decades ago. According to the U.S. Dept. of Labor, many workplaces contain spaces that are considered “confined” because their configurations hinder the activities of employees who must enter, work in, and exit them. In regards to storm and sanitary installations, entering the wet well to repair or pull a pump is considered a confined space procedure.
Bedford Park’s Water Superintendent Jim Gifford made it a priority to oversee the removal of these installations due to safety concerns and maintenance issues involved.
“The bottom line is these installations are dangerous and you worry about the employees performing maintenance,” said Gifford. “On top of the safety issues, you can’t even get parts made for the elevators that lower a worker to the bottom unless you fabricate the parts yourself, but nobody wants to fabricate the parts either,” he added.
Working together with Hoefferle-Butler Engineering of Hickory Hills, Ill., and Airy’s Incorporated of Tinley Park, Ill., Metropolitan Municipal Sales Engineer Keith Girup suggested installing separate storm and sanitary lift stations complete with a common control building and generator. Both the storm and sanitary wet wells use heavy duty submersible pumps on a guide rail system that allows a worker to easily remove a pump for service and repair without entering the wet well.  The combination of using pumps on guide rails eliminates the dangers of confined space entry procedures because there is no need to ever enter the basin.

Sanitary Lift Station
The sanitary lift station was a prefabricated polyurea coated steel basin measuring 8’ in diameter and approximately 22’ deep with 6’’ piping and valves. Inside the basin, two 15HP submersible pumps each having the capacity to pump 700 gallons per minute at 38’ of total dynamic head.
Some special features included using impressed current cathodic protection in lieu of sacrificial anodes, which over time dissolve and break down promoting corrosion of the station. Using impressed current cathodic protection known as the Metro Guard with steel stations reduces corrosion if not eliminating it entirely throughout the life of the system.
Another feature included adding trash baskets at the inlet pipe near the pumps that catch large debris and prevent the pumps from clogging. Given this station is located in an industrial park, special attention was paid to controlling the larger debris generated by the industrial customers and trash baskets were added as a preventative measure.

Storm Water Lift Station 
The storm water lift station, located next to the sanitary station, was also a prefabricated polyurea coated steel basin which measured 8’ in diameter by 19’ deep with 6’’ piping and valves. Inside the basin, two 15HP non-clog submersible pumps each move 700 gallons per minute at 38’ total dynamic head. The Metro Guard impressed current cathodic protection system also protects the steel basin from corrosion.

Controls
The brains behind any system are the controls operating it. Metropolitan Industries is proud of the fact that their U.L. panel shop can design, build and program custom packages related to any pumping application.
Bedford Park’s system incorporates the latest in variable speed PLC control logic and integrates both the storm water lift station and sanitary lift station together using a common control panel and a common 100kW natural gas generator adding a unique aspect to how the system is operated.
The controls are housed in a pre-cast concrete building with a faux brick exterior measuring 10’ long x 7’ wide x 10’ 6’’ high. The building was delivered to the jobsite ready to install by the contractor. Inside, all components such as the control panel, variable frequency drives, HVAC, lighting, automatic transfer switch, main disconnect and more were all factory pre-installed before shipment to the jobsite requiring the contractor to simply off-load and make minor electrical connections.
Now in operation, the new storm water lift station and sanitary lift station eliminated confined space applications. Metropolitan Industries, Inc., located in Romeoville, Ill., is a single source supplier of pumps, control systems and ancillary equipment serving the commercial, municipal, industrial and residential markets.
