Pre-Construction Efforts

Tree Trimming
The City is currently repairing and replacing the crumbling infrastructure of our aging water and sewer system. Because of this work, it will occasionally be necessary to trim or remove trees and vegetation that obstruct the sewer lines. For more information, please watch this brief video.

Sanitary Sewer Assessment
As a part of the Consent Decree, the City of Shreveport has begun a Sanitary Sewer Assessment (SSA) in various locations throughout the Queensboro, Westside, North Highlands, Southside and Choctaw Bayou Sub-Basins. Construction work in the SSA will include dye-water testing, and cleaning and CCTV of sewer lines. This work will be used to identify and assess defects in gravity sewer lines and manholes. Evaluation of the identified defects will then be used to prioritize the repairs needed throughout the City’s sewer system.
Work associated with SSA Phase I will be completed by May 12, 2015. SSA Phase II work is currently in progress. Click here to view the City of Shreveport project location map that includes both SSA Phase I and II project limits.

Smoke Testing Sewer Lines
The City of Shreveport is conducting a smoke test of its sanitary sewer system. This work is being performed by the City’s Contractor, Compliance Envirosystems, LLC (CES), and will be administered and supervised by the City’s consultant, Burk-Kleinpeter, Inc (BKI).

Smoke testing is one of the most efficient and cost-effective ways to locate and identify areas of the sewer system that need improvement. The smoke is harmless and will disappear after only a few minutes.

Smoke testing will take place on each sewer main throughout the city of Shreveport over the next 8 years.

Frequently Asked Questions (FAQs)
What is the benefit to the city for performing a Smoke Test?
Smoke testing is used to identify sections of sewers which may exhibit inflow during rainfall. Inflow sources are roof leaders, cellars, yard and area drains, foundation drains, abandoned building sewers, faulty connections; illegal connections and storm water drainage system cross connections. It can also detect structural damages and leaking joints in sewer pipes and overflow points in sewer systems.
What exactly is a Smoke Test?
A crew places a smoke blower over manholes and smoke is blown through the sewer system. Anywhere the smoke exits, there is potential for stormwater to enter the sewer system.

How will residents know when Smoke Testing will be performed in their neighborhoods?
Door hangers will be placed on the front door of every building on the streets to be smoke tested at least 24 hours (1 day) and no more than 120 hours (5 days) in advance. Notices will be distributed by the smoke testing field crew.

Do residents have to do anything to prepare their homes for Smoke Testing?
One gallon of water can be poured into the drain traps of floors, sinks, showers, and tubs that are not used consistently, to prevent sewer gases from entering the building and also to prevent smoke from entering the home. If smoke does enter, the resident should ventilate that affected area and consult a licensed plumber. If harmless smoke can enter through faulty plumbing, the potential exists for dangerous sewer gases to enter the home.

How are the smoke test crews recognizable in the field?
All field personnel are uniformed and carry identification badges issued by the City of Shreveport. Crew members operate from vehicles with clearly marked company’s signage. Under no circumstance will a crew member need to enter your home.

Is the smoke hazardous?
NO! The smoke that comes out of the vent stacks on houses or holes in the ground is non-toxic, harmless, non-staining, and has no odor. It does not create a fire hazard.

What if smoke comes out of a resident’s yard or driveway?
This could mean that there is a drain on the property which is connected to the house sewer line instead of the storm system. It could also mean that there is not a direct connection, but that the resident’s lateral line has breaks or cracks in the pipe that drain runoff after it has entered into the soil.

If there is smoke in the resident’s yard, does that mean the cause of the leak needs to be dug up?
In a worst-case scenario, yes, but there are many other solutions, such as disconnecting the drain or lining a portion of the house lateral without an excavation.

Does the resident need to be home when the Smoke Testing is performed?
Homeowners do not need to be home and field crews will not need to enter the residence. Field crews will record the testing by taking photos and measuring distances so the defects can be located.
