Great River Utility seeks wastewater service certificate for Harrison County expansion

The Mississippi Public Service Commission (PSC) convened on May 1, 2025, to discuss a petition from Great River Utility Operating Company LLC. The company is seeking a supplemental certificate of public convenience and necessity to acquire, construct, and operate wastewater service facilities in Harrison County, Mississippi.

The petition addresses two main issues. First, it aims to correct the service area boundaries previously granted to Great River in docket 2020 UA 145. The original boundaries for the Robinwood subdivision were incorrectly filed, and Great River currently serves about 100 customers outside their certified area. The second issue involves extending wastewater service to a new development adjacent to Great River's approved service area.

The commission's order focuses on approving Great River's certification requests while deferring the consideration of necessary infrastructure improvements to a separate filing. This approach allows the commission to thoroughly review all options and costs related to wastewater treatment for the Robinwood subdivision.

The Mississippi Department of Environmental Quality has already approved an initial treatment plan that utilizes a lagoon system. The legal description and service area map have been verified by GIS and mapping specialists. Staff members recommend granting Great River the supplemental certificate, which would enable the company to better serve its existing and future customers.

The meeting concluded with no further questions from the commissioners, indicating a smooth path forward for Great River's petition.
