Shreveport seeks extension as sewer system repairs near $1 billion cost

Shreveport, Louisiana, is seeking a multi-decade extension to complete federally mandated wastewater system upgrades as total project costs are now projected to reach $1 billion. 

The city has already spent more than $450 million addressing deficiencies identified under a 2014 EPA consent decree aimed at reducing sewer overflows and bringing the system into compliance with the Clean Water Act, according to The Center Square. The original plan called for completion within 12 years, but city officials now say an additional 15 to 20 years will be needed.

Progress has slowed in recent years due to funding constraints, with officials citing limited financial capacity to complete all required upgrades. Completed work includes sewer line cleaning and inspection, lift station repairs, manhole rehabilitation and hydraulic modeling updates for key system components.

The rising cost of the program has also placed pressure on ratepayers, The Center Square reported. Sewer rates increased 177% between 2013 and 2022, and officials say further increases could strain affordability, particularly for low-income residents.

The city is pursuing additional funding through federal loans, state grants and local bond programs, while also negotiating potential relief from $17.7 million in federal penalties tied to the consent decree.
