Answer 
_Sewer Smoke Testing:_
Sewer smoke testing is a diagnostic technique used to detect leaks, defects, and illegal connections in sewer systems. The process involves pumping a non-toxic, odorless smoke into the sewer lines, usually through a manhole or cleanout. The smoke then flows through the sewer pipes, and any leaks or defects are identified by observing where the smoke escapes.
_Smoke Testing Process:_
1. Pre-testing: Identify the area to be tested and ensure safety measures are in place.
2. Smoke Generation: Pump smoke into the sewer lines using specialized equipment.
3. Observation: Observe where the smoke escapes, indicating leaks or defects.
4. Documentation: Record the location and severity of leaks or defects.
_Purpose of Sewer Smoke Testing:_
1. Identify leaks and defects in sewer lines.
2. Detect illegal connections (e.g., stormwater or sump pumps connected to sanitary sewers).
3. Locate sources of inflow and infiltration (I/I) in sewer systems.
4. Prioritize repairs and maintenance.
_Sewer Smoke Testing Benefits:_
1. Quick and cost-effective
2. Non-invasive and non-destructive
3. Helps prioritize repairs and maintenance
4. Enhances sewer system performance and reduces overflows
By using sewer smoke testing, municipalities and utilities can efficiently identify and address issues in their sewer systems, ultimately improving public health and environmental protection.
