Romtec Utilities designed and supplied a sanitary wastewater pump skid for Taiwan Semiconductor Manufacturing Company’s manufacturing facility expansion in Phoenix, Arizona. The indoor wastewater pump skid collects and conveys sanitary wastewater within the expanding production facility while supporting reliable day-to-day operations.

Instead of using a traditional outdoor lift station, the project team selected an indoor tank and pump skid assembly installed inside the building. Romtec Utilities based the design on an existing wastewater system and improved equipment reliability, maintenance access, and integration with the facility’s building management system.

Romtec Utilities worked with LSW Engineers and the project team to develop a packaged wastewater pumping system tailored to the operational requirements of the expanding manufacturing campus.

Expanding manufacturing campuses need utility infrastructure that grows with production. Sanitary wastewater systems play a critical role by collecting and conveying flows from restrooms, support spaces, and other facility areas to the larger wastewater network.

For this project, TSMC needed a sanitary wastewater system that could serve the facility expansion, fit inside the existing building, and operate alongside established infrastructure. The owner also wanted equipment and controls that matched operating practices already familiar to facility personnel.

Rather than start from a completely new design, the project team refined an existing wastewater pump skid system and incorporated improvements identified through previous operating experience.

This approach reduced design uncertainty and built on a proven system already in service.

A sanitary wastewater pump skid collects wastewater from a facility and pumps it to the site’s larger wastewater collection network. In this application, the system needed to handle sanitary flows from the manufacturing building while meeting the owner’s hydraulic, operational, and maintenance requirements.

Because crews would install the equipment inside the manufacturing building, Romtec Utilities designed the indoor wastewater pump station to fit the available space and support accessible inspection and maintenance.

Key design objectives included:

• Reliable wastewater conveyance
• Improved system performance
• Compatibility with existing facility operations
• Straightforward maintenance
• Building management system integration
• Proven equipment and components

These requirements established the framework for the final pump skid design.

Unlike a traditional buried lift station, this project uses an indoor tank and pump skid assembly.

The system combines the collection tank, pumps, controls, and associated equipment into one coordinated package designed for installation inside the manufacturing facility. This arrangement gives operators convenient access for inspection and maintenance while keeping the system within the building’s available footprint.

Romtec Utilities worked closely with the engineer and owner to develop a facility wastewater pumping system based on the existing installation and the facility’s operating requirements.

The project team selected equipment that met the required hydraulic conditions while aligning with the owner’s preferences for proven products and long-term serviceability.

By packaging the primary components into a single skid, Romtec Utilities also simplified installation and future maintenance activities.

The project team prioritized system reliability throughout the sanitary sewer pump skid design.

Manufacturing facilities depend on continuous utility service, so Romtec Utilities and the project team reviewed previous operating experience and identified practical ways to improve the new installation. The updated design applies lessons learned while maintaining a familiar operating approach for facility personnel.

The resulting system emphasizes:

• Reliable equipment operation
• Improved maintenance access
• Practical operating requirements
• Reduced system complexity
• Proven equipment selection

Together, these improvements create a wastewater system that is easier to operate and maintain over time.

Modern manufacturing facilities use centralized building management systems to monitor mechanical and utility infrastructure.

To meet those requirements, the sanitary wastewater pump skid includes controls that communicate with the facility’s building management system through dry contacts. Operators can monitor pump skid status alongside other building systems without using a separate interface.

The controls package gives operators the information they need for day-to-day operation while maintaining a straightforward approach that aligns with the owner’s preferences.

Several organizations collaborated on this project:

• End Owner: Taiwan Semiconductor Manufacturing Company (TSMC)
• Civil Engineer: LSW Engineers
• General Contractor: UIS
• Reviewing Agencies: TSMC and LSW Engineers
• System Provider: Romtec Utilities

Together, these organizations developed a sanitary wastewater pump skid tailored to the operational requirements of the expanding manufacturing facility.

This sanitary wastewater pump skid shows how a customized pumping system can meet the unique requirements of an advanced manufacturing facility. Romtec Utilities combined an indoor tank and pump assembly with integrated controls and proven equipment to deliver a wastewater solution designed for the building’s operational needs.

Working with TSMC and LSW Engineers, Romtec Utilities developed a packaged wastewater pumping system that builds on an established design while improving equipment selection, maintenance access, and monitoring capabilities. Once installed, the system will provide dependable sanitary wastewater conveyance for the expanding Phoenix facility.
