Water System

Hanahan Steam Pumping Station Charleston Water System has been providing potable water to the citizens of Charleston since 1917, when City Council created the Commission to manage the City’s drinking water supply. Since then, technological advances in water treatment and distribution have made Charleston’s drinking water some of the cleanest, safest water in the country.

The original Hanahan Steam Pumping Station, built in 1903, is now the site of Charleston Water's Hanahan Water Treatment Plant. The building pictured here was refurbished in the 1980s to house the plant's administrative offices and laboratory staff.
