Albert Baldwin Wood and his screw pumps modernized New Orleans by bringing flood-free streets and cleaner water to the city while providing the potential for growth by pumping swamp lands dry. While Wood was never part of the local Progressive movement, his work with the pumps fit with Progressive initiatives for modernization. At first, the screw pumps removed rain water from the streets. Then New Orleans expanded the drainage to include sewerage removal and water purification. The pumps successfully drained thousands of acres of land once considered uninhabitable swamp land. This additional land extended New Orleans city limits but also aided in the acceleration of residential segregation. Cities from around the world used the designs for the screw pump and consulted Wood for advice on drainage systems.
