Albuquerque Water Authority Breaks Ground on Major Outfall Restoration Project

(ALBUQUERQUE, NM – August 21, 2024) - The Albuquerque Bernalillo County Water Utility Authority (Water Authority) recently broke ground on the Southside Water Reclamation Plant (SWRP) Outfall Restoration Project, restoring part of the Middle Rio Grande corridor where high-quality, treated effluent from the SWRP discharges into the river.

To achieve the Water Authority’s goals of conservation, clearer water, and community access, the project team developed a nature-based restoration solution. The new site design uses floodplain terraces and nature-based design, where terraces reconnect the river to its floodplain, allowing floodwaters to wash over the area, increasing groundwater connectivity and supporting native plants. The terrace-based design also stabilizes the streambanks, reducing erosion potential. The project will also create a more inviting habitat for fish and wildlife, including the Rio Grande silvery minnow, a local species endangered by climate and anthropogenic changes.

To preserve the recreational value of the area while still safeguarding the surrounding habitats, the team carved out official trails for hiking and biking, designated fishing spots, and added educational signage to promote community understanding of the river’s cultural and environmental significance. The new design also facilitates easier maintenance access with newer, more intentional maintenance roads.

“When we’ve monitored the Rio Grande Silvery Minnow, we discovered that they, and other fish, prefer our outfall water because it’s consistent, of high-quality, and has hospitable temperatures. This project will help to support the local ecosystem and ensure that fish populations continue to thrive in the years to come,” said Diane Agnew, Water Rights Program Manager at the Water Authority.

The restored outfall is expected to be completed and open to the public Fall 2025.
