On-Site Wastewater Treatment Plants
Assistance to Small Businesses and Homeowners

For over twenty years, we have been assisting businesses and homes with their on-site wastewater treatment plants (WWTPS) in areas not connected to municipal sewer services. In unincorporated areas in the Pontchartrain Basin, there are roughly 150,000 of these on-site systems . Working with parishes, we educate and support owners to ensure their systems are functioning properly and do not discharge untreated wastewater into local waterways, protecting the ecology of the watershed.

While larger municipalities like New Orleans have efficient wastewater treatment facilities, many rapidly developing areas around Lake Pontchartrain rely on on-site wastewater treatment plants (WWTPs). Unfortunately, some of these small systems are not functioning correctly, leading to water contamination in the rivers and tributaries of Lake Pontchartrain. Our data shows that these individual systems often fail at about a 50% rate. Despite significant improvements in Lake Pontchartrain's water quality over the past 25 years, the impact of sewage sources is still felt.

Our water quality team works with owners to understand, assess, and repair these systems. In some of our project work, we have improved onsite WWTP pass rate from 59% to 95%. While we focus our work on watersheds for projects, we are here to help with any questions or concerns regarding individual wastewater treatment plants. Contact us for more information. 

Bayou Bonfouca

Our latest project is in Bayou Bonfouca, where we are partnering with St. Tammany Parish. In this project, parish inspectors will conduct home system inspections, while PC will conduct water quality monitoring in the water outfall areas. By monitoring the water quality of the bayou, we will be able to see real time impacts of the inspection program.
