City officials in St. George, Utah, report that the main wastewater pipeline is within 5% of its total capacity. The pipeline, which serves St. George, Ivins, Santa Clara, and Washington City, was originally constructed in 1990 and is struggling to keep pace with the area's population growth.

The proposed $40 million project involves replacing more than 20,000 feet of aging pipe. This expansion is critical for maintaining service as the region's population continues to rise, with estimates placing the Washington County population at over 213,000 residents.

Beyond managing increased flow, the local reclamation plant plays a vital role in the region's water conservation strategy. By converting treated effluent into usable water, the facility helps support the city's needs in a challenging desert climate.
