Romtec Utilities partnered with Hydro Source and Eckermann Engineering to engineer, manufacture, and deliver a private stormwater pump station to McCoy’s Building Supply in Midland, Texas. This privately funded project supported the construction of two new buildings on a landlocked site where above-ground stormwater detention was not feasible.

To maximize usable property while meeting local stormwater management requirements, the project team selected an underground detention and pumping solution. The completed system captures stormwater in underground detention piping and conveys it to the pub right-of-way through a dedicated wet well and force main system.

Romtec Utilities served as the basis of design provider, providing engineering support, prefabrication, startup, training, and long-term warranty coverage. McCoy’s Building Supply is the final owner and operator of the system. The pump station captures stormwater in underground detention piping and conveys it to the public right-of-way via a dedicated wet well and force main system.

Midland, Texas, is a city in West Texas located in the Permian Basin, one of the most active energy-producing regions in the United States. The city was originally founded in the 1880s as a railroad stop between Fort Worth and El Paso.

The region has experienced steady growth due to oil and gas development, which has increased demand for commercial infrastructure like retail facilities, warehouses, and service centers.

With development growth in the Permian Basin comes a need for reliable stormwater management systems. Midland’s climate includes periods of heavy rainfall, which can create large volumes of runoff in a short amount of time. For commercial sites with limited space, a private stormwater pump station is often the best solution to prevent flooding and maintain compliance with local drainage requirements.

The McCoy’s Building Supply site reflects these conditions. Surrounded by development and lacking open land for drainage ponds, the project required a compact and effective solution that could manage stormwater while supporting continued site expansion.

McCoy’s Building Supply is a well-established retailer that provides lumber, building materials, and construction supplies to contractors and homeowners. With locations across several states, McCoy’s plays an important role in supporting construction and development projects.

At the Midland location, McCoy’s planned to expand operations by adding two new buildings. This expansion required a stormwater system capable of handling runoff from the increased roof and pavement area. At the same time, the system needed to fit within a fully developed site with limited space.

By installing a private stormwater pump station, McCoy’s was able to meet these requirements without sacrificing valuable land. The system allows the facility to operate efficiently while protecting the site from stormwater-related issues.

Brought into the project early by Hydro Source, Romtec Utilities supported Eckermann Engineering with system layout, design criteria, and bid documentation. The team worked directly with the engineer and bidding contractors to explain system functionality, justify the basis of design, and clarify scope responsibilities. As a result, Romtec Utilities’ solution was adopted as the basis of design for the project.

The company provided complete design documentation, including structural, mechanical, and electrical drawings, and supported multiple design revisions as part of the engineering process.

To streamline installation, all system components were integrated and prefabricated or preassembled to the maximum extent possible prior to delivery. The wet well was delivered in sections and stacked in the field by the contractor under Romtec Utilities’ guidance.

Key system components of the private stormwater pump system include:

• Precast concrete wet well
• 10-foot inside diameter
• Approximately 21 feet deep from rim to floor
• H-20 occasional traffic-rated top slab with safety grade

• Duplex configuration
• (2) Keen K12VK submersible pumps
• 20 HP, 460V, three-phase
• Explosion-proof motors

• In-well check valves
• 12-inch ductile iron discharge piping
• Dual force mains to maintain required system head

• UL-listed control panel
• NEMA 3R painted enclosure
• Primary controller: ProVu PD6000
• Primary level sensing: pressure transducer
• Secondary level sensing: (2) float switches
• Variable Frequency Drives for pump modulation
• Alarm beacon and telemetry dry contacts

The duplex pumping configuration allows the pumps to alternate operation, which helps distribute wear evenly and extend equipment life. The system can also adjust pump speed based on changing conditions, ensuring efficient performance during both small and large storm events.

By maximizing off-site prefabrication and preassembly, Romtec Utilities reduced field installation time and simplified construction for the contractor.

The primary challenge was the lack of available surface area for traditional stormwater detention. With surrounding development already in place, McCoy’s required a solution that preserved buildable space while still managing large stormwater volumes.

To address this, the design incorporated underground corrugated metal pipe (CMP) storage systems that feed runoff into a dedicated private stormwater pump station.

Additionally, the system needed to accommodate significant variability in head conditions between low-water and high-water events. This variability required advanced controls and pump modulation to maintain performance across operating conditions without overstressing equipment.

Romtec Utilities designed and supplied a complete packaged private stormwater pump station tailored to the site’s specific needs. The system combines structural, mechanical, and electrical components into one coordinated solution.

The duplex pump setup provides built-in redundancy, making sure the system can continue operating if one pump is offline. The variable speed drives allow the pumps to adjust output as conditions change, which helps maintain efficiency and protect equipment.

Advanced level sensing provides accurate control, while backup systems add reliability. Together, these features create a system that can handle changing stormwater conditions with minimal operator involvement.

Hydro Source introduced Romtec Utilities to the project team and coordinated early collaboration between Romtec Utilities, Eckermann Engineering, and the bidding contractors. This project marked Romtec Utilities’ first completed project with Hydro Source, establishing a new regional partnership in Texas.

The Mitchell Group was the general contractor, while Entrench, Inc was the civil contractor. McCoy’s Building Supply is the end owner and operator of the completed system.

The Midland, Texas, private stormwater pump station at McCoy’s Building Supply shows how smart engineering can solve complex site challenges. By combining underground storage with a compact pump station, the project team was able to manage stormwater effectively without sacrificing usable space.

Romtec Utilities delivered a fully integrated system that supports long-term performance, reduces risk, and adapts to changing conditions. Through prefabrication, advanced controls, and close coordination with project partners, Romtec Utilities provided a reliable solution for a constrained commercial site.

This project also established a successful first collaboration with Hydro Source, expanding Romtec Utilities’ footprint in the Texas market and reinforcing its role as a trusted partner for complex private stormwater pump station projects.
