Neosho water and sewer sale: Missouri PSC approves Missouri-American Water takeover

On June 24, 2026, the Missouri Public Service Commission approved Missouri-American Water Company’s request to acquire, own, operate, and maintain the water and sewer systems serving customers in and around the City of Neosho, Missouri.

For Neosho residents, the most important customer point in the PSC order is also the simplest: existing Neosho water and sewer rates are set to remain in effect until changed through a future general rate case—so rates are not automatically expected to change just because the PSC approved the agreement.

What the PSC approved in Neosho

The PSC order grants Missouri-American Water Certificates of Convenience and Necessity (CCNs) for providing water and sewer service in the approved service area around Neosho. The order also documents the agreement and the parties involved in the case.

What stays the same: Neosho rates until a future rate case

The order states that existing Neosho water and sewer rates will remain in effect until changed through a future general rate case. Residents should plan for potential transition changes, but not immediate rate changes based solely on the June 24 PSC approval.

What must happen before the deal closes

The PSC approval is a permission step—not the point where everything is automatically switched over. The order lists specific conditions Missouri-American Water must complete before it can close, including:

Filing tariff sheets and service area maps before closing on the assets.
Notifying the Commission when the transaction closes and providing status reports if closing is delayed.

How customers are expected to be informed

The order also spells out customer-transition expectations. Missouri-American Water is required to provide information to customers about their rights and responsibilities and to communicate details about the transition to company ownership.

The PSC additionally requires customer service training for staff handling Neosho accounts, plus sample billing statements and ongoing customer service reporting to Commission Staff following the acquisition.

Separate books and records: Missouri-American Water must also maintain separate books and records for the Neosho systems in line with applicable accounting requirements.

Background: where this fits in the process

This PSC decision follows the earlier agreement process that led to the Missouri-American Water request for CCNs for Neosho’s water and sewer systems. The local question now shifts to the practical next steps: what residents will see as official transition communications arrive, and how the required Commission filings/notifications roll through before closing.

Until a future general rate case is decided, the order’s key consumer message remains the same: Neosho water and sewer rates are intended to stay in effect until a later general rate proceeding.
