1. The primary purpose of a sanitary sewer collection system is to:
A. Convey stormwater to receiving waters
B. Transport potable water to customers
C. Carry wastewater safely to a treatment facility
D. Recharge groundwater
The collection system is designed to transport wastewater from homes and
businesses to a wastewater treatment plant.
2. Which gas is most commonly associated with sewer atmospheres and has a
rotten egg odor?
A. Carbon monoxide
B. Hydrogen sulfide
, C. Methane
D. Chlorine
Hydrogen sulfide (H₂S) is common in sewers and poses toxicity and explosion
risks.
3. Before entering a confined space, the atmosphere must be tested for:
A. Oxygen only
B. Combustible gases only
C. Toxic gases only
D. Oxygen, combustible gases, and toxic gases
Confined space entry standards require full atmospheric testing.
4. The minimum safe oxygen level for confined space entry is:
A. 16%
B. 18%
C. 19.5%
D. 23.5%
OSHA defines oxygen deficiency below 19.5%.
5. A sewer backup into a residence should first be addressed by:
A. Blaming the homeowner
B. Waiting for supervisor approval
C. Protecting public health and stopping the overflow
D. Issuing a citation
Immediate response minimizes exposure and property damage.
, 6. A combination sewer carries:
A. Only sanitary wastewater
B. Only industrial waste
C. Stormwater and sanitary wastewater
D. Drinking water and wastewater
Combined systems carry both stormwater and sewage.
7. The function of a manhole is to:
A. Store wastewater
B. Increase pressure
C. Provide access for inspection and maintenance
D. Filter debris
Manholes allow personnel access to underground pipes.
8. Which tool is used to remove roots from a sewer line?
A. Plunger
B. Root cutter attachment
C. Pipe wrench
D. Torque wrench
Root cutters are used with rodding machines.
9. A sudden drop in flow downstream may indicate:
A. Pipe expansion
B. Blockage upstream
C. Excess rainfall
D. Increased slope
, Reduced downstream flow often suggests obstruction.
10.The most common cause of sanitary sewer overflows (SSOs) is:
A. Earthquakes
B. Vandalism
C. Blockages from grease and debris
D. Excessive slope
Fats, oils, grease (FOG) and debris are primary causes.
11.The proper PPE for jetting operations includes:
A. Safety glasses only
B. Eye protection, gloves, boots, hearing protection
C. Sandals and mask
D. No PPE required
Jetting involves high pressure and splash hazards.
12.The primary purpose of sewer cleaning is to:
A. Improve water taste
B. Increase pipe diameter
C. Maintain flow capacity
D. Add chemicals
Cleaning prevents buildup and capacity loss.
13.The slope of a gravity sewer allows:
A. Pumping
B. Pressure buildup
