Romtec Utilities engineered and supplied a stormwater pump station project for a new Krispy Kreme location in La Habra, California – because nothing ruins a good doughnut run like a flooded parking lot.

The stormwater management system helped a global brand open a new location in a growing community, while preparing for heavy rainfall. A reliable pump system was essential to keep the site safe, dry, and ready for the rush of doughnut lovers.

Located in the northwestern corner of Orange County, La Habra is home to 63,000 residents. The area is known for its family-friendly neighborhoods, parks, and proximity to Los Angeles and the California coast. La Habra is a growing community that continues to attract commercial developments, including globally recognized brands like Krispy Kreme.

When the new store was in planning stages, the project team needed a stormwater pump station that could manage serious rainfall. The system was designed to offer reliable performance with minimal maintenance.

Romtec Utilities designed a triplex pump system tailored to specifically meet the demands of this site. Our engineering team designed the system to manage a peak inflow rate of 1,280 gallons per minute.

Here is how we designed the stormwater pump station project:
• Three Keen K4VBX pumps, each delivering 431 GPM.
• Total capacity of 1,293 GPM at 13.85 feet of total dynamic head.
• An 8-foot diameter wet well with 538.5 gallons of active volume.
• The pump cycles every 6 minutes, with no more than 10 starts per hour.
• Nolta MS1 level sensors.

The result is a system that balances performance with durability. The triplex pump system is designed to keep things running smoothly without excessive wear and tear.

The icing on the project is the control panel. Designed by Romtec Utilities, the panel is designed to operate in both manual and automatic modes.

In automatic mode, the system uses a lead-lag-lag pump cycling sequence:
• The lead pump activates first as water rises.
• If inflow continues, the second (lag) and third (lag-lag) pumps engage.
• Once water levels return to the stop elevation, the system shuts down and resets.

This smart automation ensures consistent performance of the stormwater pump station project, even during heavy rainfall.

To safeguard against reverse flow and surcharging of the stormwater pump system, Romtec integrated Tideflex inline check valves into the discharge piping. These maintenance-free valves are designed to stop backflow in their tracks, all while operating with minimum head loss.

Romtec Utilities delivered the stormwater pump station project as a complete package. This means the customer did not have to coordinate between multiple vendors or worry how things would fit together. Romtec handled the engineering, fabrication, and delivery of all the electrical, mechanical, and structural components.

Espinoza Engineering Construction Company installed the pumping system. During installation, Romtec provided on-site technical assistance to assure proper placement and connection of all elements. The startup process confirmed that all pumps and controls operated within their specified performance curves, validating the pump system’s readiness and reliability.
