How Does this Garden Save Water?

How Does this Garden Save Water?. Prospect Park Alliance. , Prospect Park Alliance waters this garden with water already used in hand sinks or in cleaning the floors in the Wellhouse comfort station, called greywater. This greywater garden, together with the composting toilets in the Wellhouse, will save an estimated 250,000 gallons of water each year from entering the city's sewer system., How It Works , A dosing basin collects the water from sinks and floor drains, which is pumped into a leaching chamber under the garden, which carries water and nutrients evenly to surrounding plants., History of the Wellhouse , Water was one of three elements that Frederick Law Olmsted and Calvert Vaux, the designers of Prospect Park, considered necessary for a park, the other two being woodlands and meadows. The Wellhouse was originally built to house the mechanical systems required to pump water that fed the Park's water system, including the Prospect Park Lake., Built in 1869, the Wellhouse is the oldest building still standing in Prospect Park. It fell into disuse sometime between 1914 and 1935, when the Park was connected to the city water supply. In order to provide more restroom facilities to Park users, Prospect Park Alliance converted the Wellhouse into a composting toilet comfort station–the first in a New York City public park., [Sidebar:] , Prospect Park Alliance sustains, restores and advances Prospect Park, "Brooklyn's Backyard," in partnership with the City. The Alliance provides critical staff and resources that keep the Park green and vibrant for the diverse communities that call Brooklyn home.
