This is a voltage drop question. To answer this question the voltage of the pump must be stated
That can't be answered until you state the voltage.
From the question it is hard to establish whether the service size is 350 amps or the service conductors are 350 MCM in parallel. If the service is 350 amps, the grounding conductor is #3 bare copper wire. Parallel 350 MCM conductors will allow for a 600 amp service. The grounding conductor for a 600 amp service is a #1 bare copper wire.
To answer this question a voltage must be given.
Nope. 350 meters is less than 1,214 feet. (350 meters = 1,148.29 feet).

A 500 MCM copper conductor will limit the voltage drop to 3% or less when supplying 350 amps for 150 feet on a 208 volt system.

350 kilometers = 1,148,293.96 feet.
350 metres = 1,148.3 feet
350 feet = 116.666667 yards
350 feet=116.666667 yards
Nope. 350 meters is less than 1,214 feet. (350 meters = 1,148.29 feet).
Grab a calculator. There are 3 feet in each yard. If there are 350 yards then you need to multiply 350 times 3 (three feet for each yard). The answer is 1,050.
