On average, it only has to be refilled every 3,000 kilometers or 1864 miles!

According to the Bosch numbers, it'd be like 6 times a year, or every 8 fillups for me.

However, BMW says it depends on driving style: every fill up when racing or every 5 if driving "fast".

"In rigorous action out on the racetrack, it is always necessary to refill the water supply whenever the car must refuel. During standard operation, the intervals between water refills are considerably longer, depending on the driving style. Even when driving faster on the motorway, it is only necessary to refill the water container roughly every five stops for refuelling. To ensure the system is as suitable as possible for daily use, it does not require any additional maintenance."

Again, hardly a concern!
