Ascension Parish Regionalization Project (APRP)

Modern Wastewater Treatment

The Problem

Ascension Parish has faced critical wastewater challenges for decades. With no central sewer system, the parish relies on hundreds of small, decentralized package plants that treat raw sewage directly within residential neighborhoods, schools, and commercial developments.

These aging systems discharge treated water into nearby ditches and waterways — many of which have become environmentally impaired over time. The result is a system that is inefficient, costly to maintain, and unable to support long-term growth.

The Solution

The Ascension Parish Regionalization Project (APRP) is bringing a long-term, reliable sewer solution to our community. The project has been approved and supported by the Louisiana Public Service Commission, Louisiana DEQ, Ascension Parish Government, and parish voters.

When complete, this project will result in stronger infrastructure, lower costs, and cleaner waterways for families and businesses across the parish.
