Question 1
An 8-inch SDR-35 PVC gravity sewer pipe is being installed using Manning's roughness coefficient n = 0.013. According to MAG standards and standard civil engineering practice, what is the minimum pipe slope required to maintain a self-cleansing velocity of 2.0 feet per second when flowing full?
Correct Answer:
0.40%
Question 2
During low-pressure air testing of a 500-foot section of 10-inch PVC gravity sewer line, the pressure is pressurized to 4.0 psig and allowed to stabilize. Per MAG / UNI-B-6 standards, what is the minimum duration required for the pressure to drop from 3.5 psig to 2.5 psig?
Correct Answer:
5 minutes 50 seconds
Question 3
A sanitary sewer manhole has an incoming sewer lateral whose invert elevation is 30 inches above the manhole main invert channel. According to standard Arizona municipal specifications and MAG details, what structure must be installed?
Correct Answer:
An outside drop pipe connection assembly
Question 4
To verify structural stability after backfilling a 12-inch ASTM D3034 SDR-35 PVC sewer pipe, a rigid mandrel deflection test is conducted 30 days post-installation. What is the maximum allowable initial pipe deflection percentage allowed by MAG Section 615?
Correct Answer:
5.0%
Question 5
When installing a gravity sanitary sewer line beneath a commercial roadway subject to heavy traffic loading, what is the standard requirement for trench pipe bedding and initial backfill zone?
Correct Answer:
Granular aggregate bedding compacted to 95% relative density extending from 4 inches below pipe to 12 inches above pipe crown
