KILLEEN – The City of Killeen has embarked on a comprehensive Sanitary Sewer Evaluation Survey aimed at identifying and addressing issues within the wastewater system. This initiative is part of a decade-long project, with approximately 10% of the wastewater lines being evaluated each year.

The initial phase of smoke testing is set to begin on Wednesday, Dec. 11, focusing on the area north of Veterans Memorial Boulevard to Fort Cavazos, between Fort Hood Street and College Street. This phase is expected to last up to three months, weather permitting.

Understanding Smoke Testing

Smoke testing involves introducing non-toxic smoke into the sanitary sewer system to detect deficiencies. During this process, residents may observe smoke escaping from the ground or smoke vents on homes.

What Residents Should Expect:

• The smoke used in testing is completely harmless.
• In rare instances, smoke may enter homes through seldom-used drain pipes. Residents are advised to run water into such drains before the test. If smoke enters a home through other means, it likely indicates plumbing issues that should be addressed by a licensed plumber.
• Properties in the testing area will receive door hangers with detailed information, including contact details for any questions.

The first phase of smoke testing will commence on Wednesday, Dec. 11, and is expected to last about three months, weather permitting. This phase will cover the area north of Veterans Memorial Boulevard to Fort Cavazos, between Fort Hood Street and College Street.

As the testing crew progresses to new areas, updates will be provided regarding the current testing zones. Over the next 10 years, various parts of the city will undergo testing, with residents being notified prior to the commencement of testing in their area.

Testing schedules may be adjusted due to weather conditions, and residents will be informed of any changes.

Smoke testing offers several benefits for evaluating and maintaining sanitary sewer systems:

1. Identifies Inflow and Infiltration: Smoke testing helps locate points where groundwater and stormwater enter the sewer system, which can lead to high flows during rain events[1][2].
2. Detects Defective Connections: It can identify buildings with improper connections, such as downspouts, yard drains, or sump pumps connected to the sewer[1][2].
3. Locates Sewer Line Breaks: The test can reveal breaks or defects in the sewer lines by showing where smoke escapes[1][2].
4. Cost-Effective: Smoke testing is a cost-effective method for identifying areas of the sewer system that need repair or improvement[1][2].
5. Improves Public Health: By identifying and fixing leaks, smoke testing helps prevent sewer gases from entering buildings, which can pose health risks[1][2].
6. Minimizes Surface Disruption: Unlike other methods, smoke testing causes minimal disruption to surface infrastructure[3].

Overall, smoke testing is a valuable tool for maintaining the integrity of the sewer system and ensuring its efficient operation.
