Question: The Golden Gate Park uses what objects to pump water?
About the article "Golden Gate Park", section "Windmills".

Candidate passages:
Golden Gate Park was planted on sand dunes and required substantial irrigation.
In 1902 the Park Commission authorized the construction of two windmills to pump ground water for park irrigation rather than purchasing water at exorbitant costs from the Spring Valley Water Company.
The Dutch Mill was completed one year later and pumped 30,000 gallons per hour.
Five years later the Murphy Mill pumped an addition 40,000 gallons per hour to the park.
Electric water pumps replaced the need for windmills in 1913 and the two mills fell into neglect.
By the 1950s the mills were in a state of ruin.

In 1902, the parks commission authorized construction of two windmills to pump subterranean water to supply the park.
The first, on the north side of the park facing the Pacific Ocean, was completed in 1903 and became known first as the North Windmill and later as the Dutch Windmill; it is now paired with the Queen Wilhelmina Tulip Garden.
The second, Murphy's Windmill, on the south side of the park, began operation in 1908.
They operated for several decades, but fell into disrepair after the park switched to electric water pumps.
The Dutch Windmill was restored in 1981, with Murphy's Windmill's restoration completed in September 2011.
Reuse of reclaimed water is an increasingly common response to water scarcity in many parts of the United States.
Reclaimed water is being reused directly for various non-potable uses in the United States, including urban landscape irrigation of parks, school yards, highway medians and golf courses; fire protection; commercial uses such as vehicle washing; industrial reuse such as cooling water, boiler water and process water; environmental and recreational uses such as the creation or restoration of wetlands; as well as agricultural irrigation.
In some cases, such as in Irvine Ranch Water District in Orange County it is also used for flushing toilets.
It was estimated that in 2002 a total of per day, or almost 3% of public water supply, were being directly reused.
California reused 0.6 and Florida per day respectively.
Twenty-five states had regulations regarding the use of reclaimed water in 2002.
Planned direct reuse of reclaimed water was initiated in 1932 with the construction of a reclaimed water facility at San Francisco's Golden Gate Park.
Reclaimed water is typically distributed with a color-coded dual piping network that keeps reclaimed water pipes completely separate from potable water pipes.
