Data center development is accelerating across the country as AI, cloud computing and high-density computing increase demand for digital infrastructure.
At the same time, owners, engineers and communities are asking an important question:
How can we build the data center capacity we need while using water and energy responsibly?
For mechanical engineers, the answer starts with the systems behind the servers.
Pumps, cooling systems, water treatment, controls and monitoring all influence how efficiently a data center operates. When these systems are properly designed and maintained, sustainability and reliability don't have to compete.
In many cases, the same engineering decisions that reduce water and energy consumption can also improve cooling performance, equipment life and operational reliability.
That's why GA Fleet believes sustainable data center development starts with smarter mechanical infrastructure.
Sustainability Is Good Engineering
Sustainability is sometimes treated as a separate ESG initiative.
For data center mechanical systems, we see it differently.
An efficient system is generally one that:
- Moves the right amount of water
- Maintains stable operating conditions
- Keeps heat-transfer surfaces clean
- Uses pumps efficiently
- Monitors system performance
- Detects problems early
- Minimizes unnecessary water loss
- Is properly maintained throughout its lifecycle
Those aren't just sustainability goals.
They're fundamentals of good mechanical engineering.
When cooling and water systems aren't performing properly, the consequences can include increased water consumption, greater pumping requirements, higher energy use and more frequent maintenance.
For mission-critical facilities, those inefficiencies can also become reliability risks.
Water and Energy Are Closely Connected
Water and energy performance shouldn't be evaluated independently in a data center cooling system.
The two are closely connected.
Scaling, fouling, poor water chemistry and inefficient flow can reduce heat-transfer performance. When that happens, pumps, chillers and other equipment may have to work harder to maintain the required cooling conditions.
Conversely, well-designed and properly maintained water systems can help:
- Maintain heat-transfer efficiency
- Reduce unnecessary pumping energy
- Improve equipment performance
- Extend equipment life
- Reduce maintenance
- Improve cooling-system stability
That's why we encourage engineers to look at the complete hydronic system rather than individual components.
The objective isn't simply to select an efficient pump or install a water treatment system.
The objective is to create an integrated cooling system that operates efficiently as a whole.
1. Optimize Pumping Systems for Real Operating Conditions
Pumps are one of the most important connections between water and energy efficiency.
Selecting a pump simply to meet maximum design flow isn't enough.
Engineers should evaluate:
- Design flow
- Total dynamic head
- System curves
- Part-load conditions
- Pump efficiency
- Variable-frequency drive operation
- Redundancy
- Controls
- Future expansion
Data centers don't necessarily operate at one fixed cooling load. As IT loads change, cooling requirements change with them.
Variable-speed pumping and properly designed controls can allow the pumping system to respond to actual demand rather than continuously operating at maximum capacity.
GA Fleet has decades of experience working with engineers on pumping and hydronic systems. We look at the pump as part of the complete system because that's where meaningful efficiency improvements can often be found.
2. Protect Cooling Efficiency With Better Water Treatment
Water quality has a direct impact on cooling performance.
Scaling, corrosion and biological growth can reduce heat-transfer efficiency and affect pumps, valves, heat exchangers and other equipment.
An effective water treatment strategy can help:
- Control scale
- Minimize corrosion
- Reduce biological growth
- Protect heat-transfer surfaces
- Extend equipment life
- Maintain system efficiency
The appropriate treatment strategy depends on the cooling system, source water, materials of construction and operating conditions.
For engineers, water chemistry should therefore be considered early in system design—not after the equipment is installed.
3. Reduce Water Waste Through Better Monitoring and Control
You can't optimize a system if you don't know how it's performing.
Monitoring and controls give operators greater visibility into cooling and water infrastructure.
Depending on the system, operators may monitor:
- Flow
- Pressure
- Temperature
- Water consumption
- Conductivity
- Equipment status
- Pump performance
- Treatment-system conditions
- Alarm conditions
This information can help operators identify problems before they become larger efficiency or reliability issues.
It can also provide the performance data owners need to evaluate water and energy conservation initiatives over time.
4. Use Leak Detection to Protect Water and Critical Infrastructure
Water leaks are a concern in any building.
In a data center, they're an even greater concern because water infrastructure operates around mission-critical electrical and computing equipment.
Leak detection can provide early warning of water where it shouldn't be.
That can help operators respond faster, potentially limiting:
- Water loss
- Equipment damage
- Operational disruption
- Repair costs
- Downtime
For data centers pursuing both reliability and sustainability goals, detecting water loss quickly makes sense from both perspectives.
5. Consider Alternative Water Sources and Reuse
As data center development expands, water availability is becoming an increasingly important part of project planning.
Depending on location and application, engineers may be able to evaluate alternatives to relying exclusively on potable water.
Potential strategies can include:
- Reclaimed water
- Treated wastewater
- Rainwater or stormwater reuse
- Optimized cooling tower water management
- Other non-potable water sources
Every project is different.
Water quality, treatment requirements, regulations, infrastructure availability and cooling-system design all have to be evaluated before an alternative source can be used.
But considering these options early gives engineers more flexibility to develop a water strategy appropriate for the facility and surrounding community.
6. Design Cooling Infrastructure for Maintainability
Sustainability isn't only about how efficiently a system operates on opening day.
It also matters how long the equipment lasts and how effectively it can be maintained.
GA Fleet and Fleet Pump & Service Group support pumping and mechanical systems throughout their lifecycle. That gives us a strong appreciation for design decisions that make equipment easier to maintain.
Engineers should consider questions such as:
Can pumps be easily accessed and removed?
Are isolation valves positioned where technicians can reach them?
Can equipment be serviced without unnecessarily disrupting critical cooling?
Are replacement parts readily available?
Can performance be measured over time?
Is there room for future expansion?
Good maintenance access can extend equipment life and help systems continue operating efficiently long after commissioning.
7. Plan for Future Data Center Growth
Today's cooling load may not be tomorrow's.
AI and high-density computing are changing thermal requirements quickly, making scalability an important sustainability consideration.
Overbuilding infrastructure on day one isn't always the best answer.
Instead, engineers can consider how the mechanical system can expand as demand increases.
That might include planning for:
- Additional pumps
- Future piping connections
- Additional cooling equipment
- Increased flow
- Expanded controls
- Additional monitoring
- Modular or prefabricated systems
Designing infrastructure that can grow with the facility can reduce unnecessary initial investment while making future expansion easier.
8. Use Prefabrication to Reduce Construction Waste and Risk
Sustainable development also includes how the facility is constructed.
Prefabricated mechanical systems move more work into a controlled fabrication environment.
Depending on the project, that can include:
- Pump skids
- Cooling-water piping assemblies
- Valve stations
- Water treatment systems
- Controls and instrumentation
- Other packaged mechanical systems
Prefabrication can reduce onsite fabrication, material handling and rework while improving quality control.
It can also allow mechanical systems to be fabricated while other construction activities are happening onsite, helping accelerate project schedules.
Through the broader Vessco Water network, GA Fleet customers can access specialized prefabrication and data center water infrastructure capabilities for projects requiring these solutions.
9. Measure Sustainability Instead of Assuming It
Sustainability goals are more meaningful when they can be measured.
For data centers, that means building monitoring into the infrastructure from the beginning.
Depending on the facility, useful measurements may include:
- Water consumption
- Cooling-system flow
- Pump energy consumption
- Pressure
- Temperature
- Conductivity
- Treatment-system performance
- Equipment operating hours
- Alarm conditions
- System trends over time
This information helps operators determine whether systems are performing as designed.
It can also identify opportunities for improvement.
A small change in pump operation, water chemistry or system control may seem insignificant on an individual piece of equipment. Across a large data center operating 24/7, those improvements can add up.
10. Better Infrastructure Can Help Build Community Confidence
Water use has become an important part of the conversation around data center development.
Communities want to know that new facilities will use local resources responsibly.
Developers and owners can help address those concerns by moving beyond broad sustainability statements and explaining the actual infrastructure being used to improve performance.
That means being able to answer practical questions:
How will the facility minimize unnecessary water use?
How will cooling-water performance be monitored?
How will wastewater or blowdown be managed?
Can alternative water sources be used?
How will leaks be detected?
How will system performance be documented?
Good engineering provides tangible answers.
And that can help owners demonstrate that water and energy stewardship have been incorporated into the facility from the beginning.

Better monitoring can identify water waste. Preventative maintenance can extend equipment life. Smarter controls can help systems respond to actual operating conditions.
These are sustainable outcomes.
They're also good engineering.
As data centers become larger and cooling requirements become more demanding, the facilities that perform best will be those that consider water, energy, reliability and maintainability together.
