required?
A. Obtain only a local building permit
B. Begin construction and submit plans afterward
C. Obtain the required state construction permit before construction
D. Register the pool only after the first inspection
Answer: Obtain the required state construction permit before construction
Rationale: Iowa requires a construction permit before construction or
reconstruction of a public swimming pool exceeding 500 square feet. The owner
,or designated representative must obtain the permit before work begins,
subject to the limited written authorization exception.
2. Who normally certifies the engineering plans and specifications for an Iowa
public swimming pool?

B. The equipment manufacturer
C. An Iowa-licensed engineer or architect
D. The local building inspector
Answer: An Iowa-licensed engineer or architect
Rationale: Iowa requires plans and specifications to be sealed and certified
under the applicable professional licensing rules by an engineer or architect
licensed to practice in Iowa, unless an authorized waiver applies.

swimming-pool requirements?
A. Replacing a worn pump with the identical type and size
B. Routine cleaning of the pool
C. Replacing the pool shell
D. Replacing a gasket during normal maintenance
Answer: Replacing the pool shell
Rationale: Iowa identifies modifications to a pool or spa shell as reconstruction.

underdrain system beneath an in-ground pool?

B. Prevent damage caused by groundwater pressure beneath the pool
C. Increase circulation velocity
D. Reduce evaporation
Answer: Prevent damage caused by groundwater pressure beneath the pool
Rationale: Iowa requires a hydrostatic relief valve or suitable underdrain system

materials under Iowa requirements?
A. Porous and easily degradable
B. Water-absorbent and flexible
C. Inert, stable, nontoxic, watertight, and durable
D. Chemically reactive to disinfectants
Answer: Inert, stable, nontoxic, watertight, and durable
Rationale: Pool construction materials must withstand continuous water
exposure and chemical treatment without creating structural, sanitary, or
durability problems.

swimming pool with a water surface area of 1,500 square feet or greater?
A. 3 feet
B. 4 feet
C. 5 feet
