Brownsville Approves SpaceX Water Infrastructure Agreement
Brownsville commissioners approved an agreement under which SpaceX will contribute up to $220 million toward Brownsville water infrastructure and wastewater projects in exchange for removing about 444 acres from the city’s jurisdiction.
The agreement connects the funding to property near the Port of Brownsville, where the land will no longer fall within the city’s jurisdiction. The infrastructure investment is directed toward projects intended to increase water and wastewater capacity.
The agreement provides for SpaceX funding of up to $220 million. The funds are designated for two projects involving water reclamation and an expansion of the Southmost Regional Water Authority system.
One project is expected to provide an additional 8 million gallons of water per day through wastewater reclamation. A separate expansion of the Southmost Regional Water Authority is expected to add about 10 million gallons of daily water capacity.
Together, the projects are expected to provide about 18 million additional gallons of daily capacity.
The agreement comes as SpaceX continues developing its South Texas operations. The property involved in the agreement is located near the Port of Brownsville, connecting the land decision with infrastructure serving the surrounding area.
The water component also adds to a wider record of water-supply pressures in South Texas. Earlier this year, several South Texas communities declared disasters over water shortages as local officials reported strain on shared water systems.Â
SpaceX Funding Covers Two Regional Water Projects
The first major infrastructure component involves a wastewater reclamation project designed to produce additional water for the region. The project is expected to add 8 million gallons of daily capacity.
Wastewater reclamation allows treated wastewater to be processed for additional water use. Under the agreement, SpaceX funding will support the project as part of the broader infrastructure investment.
The second component involves an expansion of the Southmost Regional Water Authority. That project is expected to increase the authority’s capacity by approximately 10 million gallons per day.
The two projects address different parts of the regional water system. The wastewater reclamation project adds capacity through water recovery, while the Southmost Regional Water Authority expansion increases the capacity of an existing regional water system.
The combined additions represent approximately 18 million gallons of additional daily capacity.
The funding arrangement places SpaceX in a direct financial role in the water infrastructure projects. Rather than relying solely on municipal funding for the projects, the agreement ties the infrastructure investment to the land arrangement involving the company.
Brownsville Plans Additional Water and Wastewater Capacity
The infrastructure projects will add capacity to a regional system that serves Brownsville and surrounding areas.
Brownsville uses about 21 million gallons of water each day. About 70% of that supply comes from the Rio Grande, while the remaining supply comes from groundwater desalination.
The additional capacity outlined in the agreement is therefore substantial relative to the city’s reported daily water use. The two projects together are expected to add about 18 million gallons of capacity each day.
The wastewater reclamation project is expected to contribute 8 million gallons per day. The Southmost Regional Water Authority expansion is expected to contribute another 10 million gallons per day.
The projects also involve both water supply and wastewater infrastructure. That distinction is relevant to the agreement because regional development requires systems capable of handling water supply as well as wastewater.
The funding is connected to SpaceX’s South Texas development, while the infrastructure projects themselves address regional water capacity. The arrangement therefore links a private company’s land interests with public infrastructure investment.
SpaceX’s South Texas operations include the Starbase facility near Boca Chica, where the company has continued work on its Starship launch system.
Land Near the Port of Brownsville Leaves City Jurisdiction
About 444 acres near the Port of Brownsville are included in the jurisdictional change approved as part of the agreement.

Removing the property from the city’s jurisdiction changes the municipal status of the land while establishing the financial commitment from SpaceX toward the water projects.
The property is near the Port of Brownsville, an area associated with industrial and development activity in the city. The agreement specifically connects the land decision with SpaceX’s contribution to water and wastewater infrastructure.
The land component and the infrastructure component form the central terms of the agreement approved by Brownsville commissioners.
The arrangement does not simply involve a water-project contribution. SpaceX’s funding is tied to the removal of the specified acreage from the city’s jurisdiction.
That structure makes the 444-acre property a key part of the agreement. The water infrastructure investment and the jurisdictional change were approved together as part of the arrangement involving SpaceX.
The port location also places the agreement within a region where industrial projects and transportation infrastructure intersect. Texas has separately approved a 10-year transportation program covering roads, rail, aviation and maritime projects statewide.
Agreement Connects Water Investment With SpaceX Development
SpaceX’s South Texas operations provide the development context for the agreement. The company is continuing work in the Brownsville area, while the city is addressing additional water and wastewater infrastructure capacity.
The agreement provides for up to $220 million in SpaceX contributions. The funding is directed toward projects that are expected to add a combined 18 million gallons of daily water capacity.
The first project is expected to add 8 million gallons per day through wastewater reclamation. The Southmost Regional Water Authority expansion is expected to add another 10 million gallons per day.
The agreement also covers approximately 444 acres near the Port of Brownsville. Those acres will be removed from Brownsville’s jurisdiction as part of the approved arrangement.
For Brownsville, the agreement places water infrastructure and land jurisdiction in the same municipal decision. For SpaceX, the arrangement links its South Texas development interests with funding for regional water and wastewater projects.
The infrastructure portion of the agreement provides specific capacity additions, while the land portion establishes the geographic change involving the property near the port.
Wastewater Reclamation Project
The wastewater reclamation project is expected to add 8 million gallons of daily capacity. It is one of two infrastructure projects identified for SpaceX funding under the agreement.
The project uses treated wastewater as part of the additional water supply capacity planned through the agreement.
Southmost Regional Water Authority Expansion
The Southmost Regional Water Authority expansion is expected to add approximately 10 million gallons of daily capacity.
Combined with the wastewater reclamation project, the expansion is expected to provide about 18 million additional gallons of capacity each day.
Property Near the Port of Brownsville
The agreement involves approximately 444 acres near the Port of Brownsville. The property will be removed from Brownsville’s jurisdiction as part of the arrangement involving SpaceX.
The jurisdictional change is tied directly to the company’s commitment to contribute up to $220 million toward the specified water and wastewater projects.
