Power Use and Infrastructure: Electric distribution service for the proposed data center will be provided by CoServ, with upstream transmission service by Brazos Electric Power Cooperative. Both companies use deliberate planning processes intended to maintain a reliable supply for all of their members. Relative to other large campus data center developments or “hyperscale” projects, Project Tomahawk will be a considerably smaller, single-building development with lower electricity demand. 

• Data centers are required to pay for the full cost of the new power lines and equipment needed to serve them. Data centers enter into agreements with their utility providers covering the site-specific infrastructure built to serve the facility, and long-term service agreements that ensure data centers fully pay for their energy usage. 

• For Project Tomahawk specifically, the Project will pay for upgrades required to serve the site, which is expected to be limited. The property directly adjoins the existing Brazos Substation, which will be upgraded at the developer's expense to serve Project Tomahawk. By funding these upgrades, Project Tomahawk safeguards public finances while supporting the resiliency of the grid. No new substation or transmission lines will be required to serve Project Tomahawk. Additional safeguards are put in place through the contractual requirements in the electric service agreement that ensure residents do not incur costs because of the Project. 

 

Water Use: Project Tomahawk will not use water for evaporative cooling purposes. The Project is being designed to use a modern closed-loop cooling system, which functions much like an automobile’s radiator: the system is filled once, and rarely requires topping off (or discharge) if properly maintained. This contrasts with the evaporative cooling equipment sometimes used in industrial or legacy data center facilities, which use considerably more water and are the source of much of the public concern about data center water use. Ongoing water needs at Project Tomahawk are limited primarily to standard domestic needs, such as bathrooms and kitchen facilities. 

 

The Project will connect to the Town of Prosper municipal water system. The Town dictates the amount of water made available for the Project to utilize, and Project Tomahawk must design the facility around that available capacity. The Town prioritizes the needs of local residents and businesses, while protecting future growth. 

 

While the Project is in the early stages of design, so quantities may vary upon completion of design and engineering, the assumptions for the system’s water use are as follows: 

• The system is filled one time with roughly 65% of the water required to fill a standard Olympic-size swimming pool. This initial fill is engineered to be a non-recurring commissioning event. Should the Town of Prosper elect not to supply water for the initial fill, water can be purchased and trucked in from commercial water vendors elsewhere in the region rather than drawing on municipal supplies. 

• The same water circulates continuously through a sealed loop; once commissioned, the system is not routinely refilled or flushed.

• Ongoing water use will primarily be utilized for standard domestic needs (toilets, sinks, drinking water for employees).

• The Project’s ongoing water use is expected to be approximately 110,000 gallons per year, which equals approximately 301 gallons per day on an average basis.  

• The Town of Prosper publishes an official, adopted engineering assumption for the water demand of a single-family detached home: the Town’s Engineering Design Standards (link) directs that Maximum Daily Demand for single-family land use be calculated as “3.5 persons per lot x 200 gallons per person per day,” or 700 gallons per day per lot.  

• The Project’s entire ongoing water use is about 43% of the maximum-day design demand the Town’s engineering standard assigns to one single-family home ​

• White Rose Partners will work with the Town of Prosper and applicable state authorities to ensure adherence to all federal, state, and local environmental and wastewater regulations.

Noise and Vibrations: Project Tomahawk is designed so that no perceptible sound is generated at neighboring property lines, and data centers do not produce ground vibration. Data centers utilize mechanical equipment, such as chillers and fans for cooling and backup generators for emergency power, which can emit sound during operation.

 

Project Tomahawk will implement several mitigation methods to minimize impact on surrounding properties and to comply with all applicable federal, state and local requirements. Project Tomahawk is self-imposing a 65-decibel maximum limit at the property boundary to ensure impacts to neighboring properties are minimized. The Project will utilize design and operational standards to minimize even these noise impacts.

 

Project Tomahawk’s sound impact will be limited in the context of the site’s existing conditions and its distance from nearby properties: 

• The existing substation adjoins the site directly to the west 

• FM 1385, a major arterial roadway, and Parvin Road generate traffic noise across the site 

• The nearest existing homes are located across FM 1385, more than a quarter mile west of the proposed building 

• A wooded corridor runs along the eastern and southern edges of the property, providing an existing natural buffer that helps mitigate any potential sound generated on-site 

 

Per the proposed Planned Development Standards, the Project will be required to include:  

• A 30-foot-wide double row of trees and shrubs around the south and east property line  

• A 15-foot-wide row of trees and shrubs around the north and west property line 

• A sound-dampening screening wall or screening around the mechanical equipment 

 

Due to state-of-the-art equipment with internal sound dampening features, physical sound barriers surrounding all exterior equipment to reduce sound transmission, and landscape buffers, including mature trees and shrubs for both sound and aesthetics, at neighboring properties is projected to be below existing ambient conditions. 

​

Kimley-Horn, an engineering consultancy, produced a comprehensive sound study for the Project. Ambient sound levels were measured at two locations on and near the property over a 24-hour period from June 29 to June 30, 2026: one adjacent to the existing electric substation to the west, and one at the northeast boundary of the site. The measured 24-hour average existing sound levels were between 59.7 dB(A) and 70.8 dB(A) - that is equivalent to a normal conversation and vacuum cleaner range. See environmental noise comparison chart below (click to enlarge):

The acoustic engineer then developed a model that projected conditions once the data center is operational. The model factors in the typical equipment used, screening and buffering, and the site’s distinct features.

• Even in a “worst-case” emergency scenario in which all backup generators are operating during a power outage, the facility’s projected sound levels at surrounding locations are estimated to be between 42 and 55 dB(A). This is less than the existing average sound conditions measured at the site, and is similar to that of an office park.

• Backup generators exist for one purpose: maintaining operations during a utility outage. Maintenance testing consists of brief exercise runs of individual units or small groups, conducted during daytime hours, never at night, and never with the full generator fleet operating simultaneously. 

• Under Federal statute, all maintenance checks and readiness testing are capped at 100 hours per calendar year. Typical annual maintenance and testing for each generator are considerably less than that ceiling. In Texas, these units are also regulated by the Texas Commission on Environmental Quality. ​​

Views: The facility has been designed to reflect the character of Prosper, with architectural detailing, materials, and landscaping that align with the Town’s design standards and the surrounding built environment. Our goal is a building that feels like a natural fit for the community. Because the property does not front an existing public street and sits behind the existing substation and adjoining properties, the building will not be directly visible from FM 1385 in the way a roadside development would be. Here are renderings of the proposed building: ​​​
