When people think about building a hyperscale data center, they usually picture substations, generators, cooling plants, and miles of fiber optics. One critical system rarely gets much attention: wastewater management during data center construction.
Yet for many large hyperscale data center campus projects, managing wastewater can directly impact the construction schedule.
That was the challenge facing a hyperscale data center project in Pennsylvania, where the owner needed a reliable way to measure and control wastewater discharge while the campus was still under construction.
Working with Garney Construction and Kimley-Horn, Vessco Water Platform Partners Sherwood Logan & Associates, Pumpcon, and Electric Pump delivered a factory-integrated packaged wastewater metering and pumping system that helped keep the data center construction project moving while maintaining compliance with local wastewater discharge requirements.
The system meters waste cooling water and sanitary sewer to the local wastewater treatment plant (WWTP) as they are only permitted to waste a certain volume of water daily before their buildout is put online. Sherwood Logan provided the equipment package which consisted of FRP Shelter, Associated Valves, Actuators, and FlowMeters, and Pumpcon & Electric Pump supplied pumping systems and Associated Controls. The pump station is monitored and adjusted remotely from Electric Pump utilizing an EWON, so adjustments to the program are simple and fast for the customer and engineer.
The project illustrates how engineered, packaged water infrastructure can solve real construction challenges while reducing startup risk for mission-critical data center facilities.
Why Wastewater Discharge Is Limited During Data Center Construction
Many people assume wastewater restrictions are based solely on environmental concerns. In reality, they’re often driven by the capacity of the local wastewater treatment system.
During construction and commissioning, hyperscale data centers generate significant volumes of wastewater from activities such as cooling system flushing, hydrostatic testing, equipment cleaning, and startup of mechanical systems. These temporary flows can be much higher than the facility’s normal operating discharge.
At the same time, the permanent site infrastructure, or even portions of the municipal sewer system serving the project, may not be fully online.
To protect wastewater treatment plant capacity and remain within their own environmental permits, municipalities commonly establish temporary daily discharge limits until construction is complete.
For contractors, exceeding those limits can slow commissioning or require construction activities to be delayed until additional discharge capacity becomes available.
The solution is accurate metering, controlled pumping, and the flexibility to adjust system operation as startup progresses.
The Challenge
For this hyperscale data center construction project, wastewater from both cooling system operations and the sanitary sewer had to be carefully measured before being discharged to the local wastewater treatment plant (WWTP).
The project team needed a system that could:
- Accurately meter wastewater discharge
- Maintain compliance with daily discharge limits
- Support a fast-moving construction schedule
- Adapt quickly as commissioning activities changed
- Reduce the need for repeated onsite programming and service visits
Meeting all of those objectives required more than individual components. It required an integrated solution.
The Solution
Sherwood Logan supplied a complete packaged wastewater metering system that included:
- Fiberglass reinforced plastic (FRP) equipment shelter
- Precision flow meters
- Automated valves
- Electric actuators
Pumpcon and Electric Pump completed the package by engineering and integrating:
- Pumping systems
- PLC-based controls
- Startup and commissioning services
- Secure remote communications using an EWON industrial gateway
Instead of coordinating multiple suppliers in the field, the contractor received a complete system designed, assembled, and commissioned to work together from day one.
Remote Support Accelerated Commissioning
Construction schedules rarely stay static, especially on large data center campuses.
As startup activities progressed, operating conditions evolved and control logic needed to be refined.
Because the packaged system included secure EWON remote connectivity, Electric Pump engineers could monitor performance and modify PLC programming without traveling to the jobsite.
That allowed the contractor and engineer to respond quickly as commissioning requirements changed, reducing delays and minimizing downtime.
For hyperscale data center projects where every day matters, remote engineering support can significantly improve startup efficiency.
Project Results
The completed packaged pump station now provides the data center with accurate metering of waste cooling water and sanitary sewer flows while helping the project remain within permitted wastewater discharge limits during construction and startup.
Key Benefits
- Accurate metering of wastewater discharge to support permit compliance.
- Remote monitoring and PLC programming through a secure EWON gateway.
- Faster commissioning with fewer onsite service visits.
- Factory-integrated equipment that reduced installation and startup complexity.
- Turnkey delivery by Sherwood Logan, Pumpcon, and Electric Pump.
Why Packaged Water Systems Make Sense for Data Centers
Every hyperscale project is under pressure to shorten schedules, reduce field labor, and improve reliability. Factory-integrated wastewater systems help accomplish all three.
Compared to traditional field-built installations, packaged systems offer:
- Faster installation
- Factory-tested performance
- Simplified startup
- Improved quality control
- Reduced field coordination
- Easier long-term maintenance
- Greater consistency across multiple campuses
As AI, cloud computing, and high-density liquid cooling continue to drive larger data center developments, these advantages become even more valuable.

Frequently Asked Questions
Why do municipalities limit wastewater discharge during data center construction?
Large volumes of wastewater generated during cooling system flushing, hydrostatic testing, and commissioning can temporarily exceed the available capacity of local wastewater treatment plants. Municipalities often establish daily discharge limits to protect treatment operations and remain compliant with their own environmental permits until permanent infrastructure is fully operational.
Why is wastewater metering important for hyperscale data centers?
Accurate flow measurement allows contractors and owners to monitor wastewater discharge in real time, helping ensure compliance with permit limits while keeping construction and commissioning activities on schedule.
What is a packaged pump station?
A packaged pump station is a factory-engineered system that combines pumps, controls, valves, instrumentation, and supporting equipment into a single integrated solution that arrives ready for installation and startup.
How does remote monitoring improve data center commissioning?
Remote connectivity allows engineers to monitor system performance, troubleshoot issues, and update PLC programming without traveling to the site. This shortens response times, reduces service costs, and helps projects stay on schedule.
What is an EWON industrial gateway?
An EWON gateway provides secure remote access to industrial automation systems, allowing authorized engineers to monitor equipment, diagnose issues, and make PLC programming changes over a secure connection.
Why are factory-integrated systems becoming more common on data center projects?
Factory-built systems reduce field labor, improve quality through factory testing, simplify installation, accelerate commissioning, and provide more consistent performance across multiple projects.
