Residents could gather water in jugs, buckets, and other containers from several fountains located throughout the city. Water was constantly flowing to these fountains since the 'tap' was always turned on. The pressure in the water was just gravity at work. All the pressure was produced by the water flowing downwards as it entered the city by aqueducts from the highlands. They used a siphon, which was essentially a larger tube for water traveling downhill and a smaller passage for water moving back upwards, producing pressure, as one method of transporting water uphill. The only method to increase water pressure was to move the same volume of water through a smaller opening, like when you place your thumb over a hose's end. Engineers would either build a wider tunnel for water to flow through or design additional channels for water to reach its destination if a bathhouse or community fountain needed more water. While this doesn't necessarily increase water pressure, it does imply that the fountain and bathroom might utilize more water. As the system grew, the supply was simply increased by adding more aqueducts. The Aqua Claudia entered the city via the Esquiline and was spread from there to various locations inside the city, but over time, Rome developed to have five aqueducts supplying the city.
On December 8, 1941, the United States Congress declared war ( Pub. ... 795) on the Empire of Japan in response to that country's surprise attack on Pearl Harbor and declaration of war the prior day. It was formulated an hour after the Infamy Speech of President Franklin D. Roosevelt.
