Short factual summary

On August 29, 2026 the Brownsville City Commission approved a Memorandum of Understanding (MOU) with SpaceX that provides for up to $220 million in funding for qualifying water and wastewater projects serving Brownsville and Cameron County, and on second and final reading approved Ordinance No. 2026-1823 to disannex approximately 444.45 acres (Tract A, Share 7 of the San Martin Grant) from the City’s corporate and extraterritorial jurisdiction (ETJ).

What happened

  • The Commission approved an MOU between the City of Brownsville and SpaceX for the benefit of Brownsville Public Utilities Board (BPUB) and the Southmost Regional Water Authority (SRWA) that provides an initial $40 million escrow contribution followed by six quarterly payments of $30 million, for a maximum contribution of $220 million. Funding is restricted to qualifying water and wastewater projects and will be released as project milestones are met. The agreement does not constitute a purchase of water capacity, an ownership interest, or a prepayment of utility rates. (City of Brownsville civic alert)
  • The approval occurred during a special meeting at City Hall on August 29, 2026; the Commission also approved on second and final reading Ordinance No. 2026-1823 to disannex approximately 444.45 acres (and adjacent right-of-way) from the City’s corporate and ETJ boundaries; the land is listed in the ordinance as part of Tract A, Share 7 of the San Martin Grant in Cameron County. (City of Brownsville civic alert)
  • Projects identified under the MOU include potable reuse and wastewater reclamation work capable of increasing water supply by approximately 8 million gallons per day (mgd), and an SRWA plant expansion capable of increasing supply by approximately 10 mgd. BPUB is seeking to increase SRWA production from 7.5 mgd to 10 mgd with a long-term goal of reaching 20 mgd. The MOU notes an initial optimization at about $46.8 million and a potential 20-mgd expansion estimated at about $202 million. All projects will remain subject to applicable engineering, permitting, legal and milestone requirements. (City of Brownsville civic alert)

What it means locally

If you own land in or near Brownsville, or are weighing options for future development, the MOU and the disannexation are two separate jurisdictional events to track:

  • Funding signal: The MOU establishes a source of conditional capital intended specifically for qualifying water and wastewater projects administered through BPUB and SRWA. That funding is milestone-driven and restricted to qualifying projects; it is not an immediate purchase of water rights or capacity. Developers and landowners should note that the availability of capital for specific projects depends on engineering, permitting, and milestone approvals described in the City notice. (City of Brownsville civic alert)
  • Capacity targets: The civic alert lists two concrete capacity targets under consideration — about +8 mgd from potable-reuse/wastewater-reclamation projects and an SRWA expansion of about +10 mgd — and states BPUB’s operational goals (from 7.5 mgd toward 10 mgd, with a long‑term 20 mgd target). These are planning figures tied to the MOU and to further project approvals, rather than guaranteed supplies. (City of Brownsville civic alert)
  • Jurisdictional change: The Commission’s second‑and‑final reading disannexed about 444.45 acres from City corporate limits and ETJ. That action changes which municipal jurisdiction applies to that land; the civic alert identifies the area as part of the San Martin Grant (Tract A, Share 7). For landowners, a disannexation can affect which local ordinances, permitting paths, and municipal services are involved — but the City notice emphasizes project‑by‑project engineering and permitting requirements rather than immediate service changes.

Mayor John Cowen Jr. is quoted in the City notice stressing the importance of increasing water capacity to plan responsibly for growth. The notice underlines that the agreement’s funds are aimed at regional resilience and are structured to be milestone‑based. (City of Brownsville civic alert)

Your next step

If you are a landowner evaluating future development or need to understand how these decisions could affect permitted uses, utility connections, or the timing of infrastructure availability, start by reviewing the City of Brownsville civic alert linked below and confirm jurisdictional status for your parcel with City and County offices. The City notice is the official record for the MOU terms, the funding schedule, the capacity targets, and the disannexation ordinance. (City of Brownsville civic alert)
