100-Year Storm

Meet 100-Year Storm Flows with Site-Specific Pump Station Designs

Stormwater Pump Station Discharging into Groundwater Retention Basin

Pumps & Engineering for Very-High Flow Flood Control Systems

Romtec Utilities engineers pumping systems for stormwater management and flood control utilizing axial flow pumps, vertical turbine pumps, and other pump technologies capable of handling very-high flow rates. These pumps and other engineering features are great for flood control systems.

Flood Control Pumping to Handle the 100-Year Flood for Your Site

Your system will be engineered for flood control to meet all types of stormwater events. Whether it’s the 100-year flood or typical seasonal flooding, Romtec Utilities engineers’ systems that “ramp up” as the water rises. These systems can even be engineered to shut off if the flooding is unmanageable.

Get Budget-Friendly Configurations for Stormwater Management Solutions

Stormwater pump station designs typically are more flexible than for sewer. Using parallel force mains, jockey pumps, and limited redundancy can all reduce the complete system cost. Romtec Utilities will make sure your 100-year flood pumping system will have an economical and functional design.

Complete As-Built Drawings with O&M Documentation

After your system is completed, commissioned, and tested, Romtec Utilities provides on-site training with O&M documentation for your flood control system. Since the 100-year event pumping capabilities are not required often, we also supply as-built drawings for your records to assist with long-term system management.

Net Lease Alliance 1
Net Lease Alliance | Stormwater Lift Station
200 GPM | 12.4′ TDH

NLA Spring Valley LLC was constructing a commercial development and in need of a stormwater lift station. This Romtec Utilities stormwater pump system was needed for small and 100-year storm events for a commercial development.

Official Logo for Orange County Water Distrct
Orange County | Stormwater Lift Station
1347 GPM | 72′ TDH

This project is a new lift station handling low flows in the Santa Ana Delhi Channel in Newport Beach, California. This system collects stormwater in a 10’ inner diameter (ID) wet well that reaches 32’ in depth. In the bottom of the well, three Ebara 20 horsepower (HP) submersible pumps sit ready to pump out the water.

Snohomish County Washington
Snohomish County | Estuary Restoration Pump Station
4170 GPM | 26.5′ TDH

Romtec Utilities designed, supplied, and manufactured a powerful stormwater pump station with an integrated control building. The pump station was installed as part of a large estuary restoration project and is used to prevent inland flooding.

Port of Portland Airport Parking Structure
Portland International Airport | High Volume Stormwater Pump Station
18,140 GPM | 10.62′ TDH

The Portland International Airport (PDX) needed a very large pump station to discharge high volumes of stormwater to a runoff creek from one of its runways.

Magnolia Public Schools 400X400
Magnolia Pacific School | High Flow Stormwater Pump Station
3146 GPM | 21.3′ TDH

One aspect during the construction of Magnolia Pacific Technical School was a stormwater pump station. This system would handle extremely high flows of stormwater and pump it to treatment.

Indian Springs Resort | Large Stormwater System
6800 GPM | 15.7′ TDH

The Indian Springs Resort needed a new pump station designed to handle high flows of stormwater runoff from a collection storm drain. This stormwater system was designed with large 40hp Ebara pumps to meet the flow requirements.

Romtec Utilities provides full engineering and design services to meet the specific goals of your project. Romtec Utilities’ Engineers are experts in water conveyance systems across a wide array of water types and applications. We work with our clients through every step of the process, from preliminary designs and budgetary estimates, submittal and review processes, installation, and all the way through start-up, training, and warranty.


Project Support

With Romtec Utilities you gain the support of our dedicated project management team at every step-from planning through installation. Romtec Utilities covers a vast scope of services that help execute the design, supply, construction, testing, and training of your pump system to ensure its success at the site location.



Romtec Utilities provides a high level of system prefabrication prior to delivery of the system to the jobsite. This greatly reduces construction cost and installation time, as well as potential project delays and change orders. This high level of prefabrication can often reduce installation time from weeks to days. Additionally, Romtec Utilities takes pride in our quality control processes, ensuring that when the system is delivered to the job site everything will function as designed.



Romtec Utilities ensures the quality and success of every pumping system from the early stages of design, all the way through installation and construction. Romtec Utilities will send experienced installation advisors to the site who will advise the installing contractor throughout the installation process providing all parties with the reassurance that the station is constructed and ultimately functioning as designed.



Romtec Utilities’ startup, testing, and training services are essential to the success of any pumping system. Following installation our technicians are on-site working directly with all parties to field check the control panel, operate the pumps, perform system testing, and provide world class training to all maintenance personnel.



With Romtec Utilities, every complete pump station is covered with a standard one-year warranty. Romtec Utilities also provides ongoing support from our entire team throughout the lifetime of our products. This support is provided to ensure that every pump and lift station project is successful.
