— About TRWC

Who we are & what we do

A cooperative built on regional collaboration, shared infrastructure, and one mission: keeping first responders connected across every jurisdiction.

— Our Story

Built on regional collaboration

The Topaz Regional Wireless Cooperative (TRWC) was established in 2008 by the City of Mesa, City of Apache Junction, Towns of Gilbert and Queen Creek, and the Superstition Fire and Medical District to jointly operate a regional radio system that is modern in its management, has equity in membership, and provides for support and future growth.

The TRWC has since expanded to include the Fort McDowell Yavapai Nation, Rio Verde Fire District, Fountain Hills Fire Department, and American Medical Response — growing into a robust regional public safety communications network serving the East Valley.

Membership occurs through an Intergovernmental Agreement (IGA) establishing an initial 5-year agreement with automatic 5-year renewals.

Connecting First Responders Across the Region

The TRWC’s primary focus is meeting the operable and interoperable communication needs of Public Safety and General Government Service Entities, ensuring that when seconds matter, every voice is heard.

The Board of Directors governs the TRWC’s continued development and operations, adhering to core principles of regional cooperation, shared infrastructure, and public safety excellence.

— Joining The Cooperative

Membership & Participation

The Governance Model establishes an Administrative Manager (City of Mesa) and the Board of Directors. The Administrative Manager appoints an Executive Director with Board approval. All matters are decided by a numerical vote of the Board of Directors, with weighted voting allowed as requested by a member. Membership into the TRWC can occur at four levels, each with different rights, responsibilities, and levels of network access.

Full Member

Full voting rights, complete network access, and equity in the cooperative. Requires execution of the IGA and ongoing financial commitment.

Associate Member

Non-voting network access for entities under contract to a Member, authorized by the Board. No Board representation.

Interoperability Participant

Authorized for intermittent interoperable situations as approved by the Board. No voting rights or Board representation.

Conditional Participant

Network access for special events, tactical situations, or emergency circumstances as authorized by the Board or Executive Director.

Financial Commitment

Participation in the TRWC requires a financial commitment from each participating entity. Costs are designed to be completely self-funding, with the Administrative Manager overseeing financial administration and equitable cost distribution.

Operational, maintenance, and capital costs are completely self-funded by member subscribers.

Additional funding can be obtained through special assessment fees and grants.

Costs are spread equitably over TRWC Areas and their respective system subscribers.

Optional services from Mesa may include dispatch and maintenance services depending on need.
