Amazon Web Services is proposing an 18-building data center campus spanning approximately 600 acres near Trenton in Butler County, Ohio. The estimated $5 billion development has raised concerns about water consumption, electricity demand, environmental impacts and farmland conversion. Trenton voters are scheduled to decide Issue 17, a proposed restriction on large-scale data centers, on November 3, 2026. The project’s future also depends on annexation proceedings and other development approvals.
Amazon Web Services is proposing an 18-building data center campus on approximately 600 acres near Trenton, Ohio.
The proposed development, estimated to represent a $5 billion investment, comes ahead of a November 3 vote that could restrict large-scale data centers in the city.
Amazon data center proposal draws attention in Butler County
Amazon Web Services (AWS), the cloud computing division of Amazon, is pursuing plans for a large data center campus near Trenton in Butler County.
The proposed development would cover approximately 600 acres of farmland along Wayne Madison Road and Hawkins Road. The campus would contain 18 buildings designed to support computing infrastructure for cloud services and other digital applications.

According to local reporting, the project could represent an investment of approximately $5 billion. However, the proposal remains subject to development-related decisions, and the company has not secured all the approvals necessary to proceed.
Amazon representatives presented information about the proposed project during a community open house at Edgewood Middle School on October 15, 2026.
The meeting gave residents an opportunity to learn about the development and ask questions about its potential effects on the surrounding community.
The proposal has become a point of debate over whether the potential economic benefits of large-scale data centers outweigh their demands on local infrastructure and natural resources.
Water use and electricity demand raise concerns
The proposed Amazon data center campus has prompted questions about its environmental footprint, particularly its projected water consumption and electricity requirements.
Data centers house servers and other computing equipment that support cloud computing, digital applications and artificial intelligence. These facilities require substantial electricity and cooling systems to maintain reliable operations.
During the October 15 community meeting, Amazon representatives discussed the proposed facility’s cooling systems and resource requirements.
According to WVXU’s report, AWS projected that the development could use up to 378 million gallons of water annually, averaging approximately 1 million gallons per day. The company indicated that the facility would primarily rely on air cooling, with water-based cooling needed during certain periods.
These figures are projections, not measurements of actual consumption from an operating facility.
Residents have also questioned how the project could affect electricity infrastructure, utility costs, noise levels and the surrounding environment.
The proposed campus would replace a substantial area of farmland with an industrial development, raising additional concerns about land use and the long-term character of the community.
The discussion reflects a broader debate across Ohio and other states as communities weigh the economic opportunities associated with data centers against the infrastructure and environmental demands of these facilities.
Trenton voters to decide on proposed data center restrictions
The proposed development comes ahead of a November 3, 2026, vote on Issue 17, a proposed amendment to Trenton’s city charter.
The measure would prohibit large-scale data centers exceeding specified electricity-demand thresholds, including facilities with aggregate monthly electricity demand or peak load exceeding 25 megawatts.
A yes vote would support the proposed restriction, while a no vote would oppose the amendment.
The outcome could affect the regulatory environment for large data center projects in Trenton. However, the ballot measure and the Amazon project’s development approvals are separate matters.
The election has become an important part of the local debate, with residents considering questions about industrial development, resource consumption and community decision-making.
The result could influence the project’s future, although other applicable land-use and legal requirements would still need to be addressed.
Annexation setback complicates development plans
Amazon’s proposal has also encountered a complication involving the land needed for the campus.
In September 2026, Trenton and other petitioners withdrew an annexation request involving approximately 601 acres in Madison and St. Clair townships.
The withdrawal followed efforts to advance the proposed development. According to WVXU’s October 15 reporting, the petitioners reserved the right to submit another annexation request after the November election.
The withdrawal does not permanently end the project, but it complicates the process of bringing the proposed site into Trenton’s jurisdiction.
WVXU also reported that Amazon had not purchased the land for the proposed campus.
The project’s future will therefore depend on several factors, including the outcome of the November vote, the status of future annexation efforts and the applicable development approvals.
For residents, these issues raise questions about how local governments should manage large industrial projects and how much influence communities should have over developments of this scale.
Potential economic benefits remain a key consideration
The proposed Amazon data center could bring substantial investment and construction activity to Butler County if the project advances.
However, the estimated investment does not establish how many permanent jobs the campus would create or how much tax revenue local governments could receive.
Those figures are important for evaluating the proposal alongside concerns about electricity demand, water consumption, noise and land use.
Residents and officials will also need to consider whether existing infrastructure can accommodate the development and whether the anticipated economic benefits would justify the associated costs.
As the November 3 election approaches, the proposed Amazon data center remains a significant issue for Trenton and the surrounding Butler County communities.
The election result, along with future land-use decisions, could help determine whether the project moves closer to construction or faces additional restrictions.
