About GCPWD

Garden City Park Water District was founded in 1922 and serves the residents of our community with safe, clean drinking water. We serve almost 6,500 residential customers and approximately 650 commercial customers in a three square mile area. The estimated population within the District is 20,000.

On average the District pumps about 1 billion gallons of water each year, with July and August being the months of peak demand and February being the month with lowest demand. 

Our water comes from six wells with two water storage towers, four underground storage tanks and six treatment plants. The District’s water system consists of about 76 miles of 6 inch to 24 inch distribution mains. Garden City Park Water District has connections with six neighboring water districts (Western Nassau Supply, Albertson, Manhasset-Lakeville, Mineola, Williston Park and Garden City).
