Nope. With respect to NYC I believe you’re mistaken. 97% of NYC water is gravity fed from three reservoirs. https://www.nyc.gov/html/nycwater/html/drinking/reservoir.shtml https://www.nyc.gov/html/nycwater/html/drinking/reservoir.sh... “The NYC Aqueduct is a pressure tunnel (a gravity feed system) with hydraulic head provided by a 300 m difference in elevation between the watershed headlands in upstate New York and the distribution area (NYC).
