A few questions weren’t answered in my story about San Diego’s largest water users today:

How much water does it take to keep the Balboa Park Golf Course green?

The city used 116 million gallons in the last year — enough for 700 families. That’s down 15 percent from the previous year, when 137 million gallons were used.

As a standalone facility, the course would be the city’s 14th-largest user, consuming more than three Marriott hotels (downtown, La Jolla and Mission Valley) or the Poway Unified School District.

What role do cruise ships play in the Unified Port of San Diego’s consumption?

They consume about 27 percent of the water the port buys from the city. The agency, which is the city’s ninth-largest user, bought 216 million gallons of water in the last year, according to city statistics.

Port spokesman Ron Powell said the district cut consumption in its buildings by 25 percent and in its parks by 35 percent — conservation gains he said were outweighed by thirsty cruise ships filling up their potable water tanks before leaving port.
