Ancient Plumbing: Egyptians and Indians (4000-2500 B.C.) The first evidence of plumbing is from the ancient Egyptians and Indians. They developed systems of copper piping to transport water from natural sources like wells and springs to homes and public baths.

Modern Plumbing Systems Modern plumbing avoids cross connections to prevent cross-contamination. This keeps the water in our homes clean and safe at all times. Plumbing valves allow us to control and direct water for its use.

One of the oldest known plumbing systems was created by the ancient Egyptians around 4000 – 2500 B.C. Since their lives depended on the ebb and flow of the Nile River, Egyptian engineers created and used a very intricate piping system to keep the water flowing where it needed to go.
