Water mains are large pipes that transport fresh water from treatment plants to homes and businesses. They are a crucial part of a city's water supply system, ensuring that clean water is delivered efficiently. These pipes are typically buried underground and can vary in size, depending on the amount of water needed in a specific area. When water mains break or leak, it can lead to significant issues, such as water shortages or damage to roads and buildings. Local governments are responsible for maintaining and repairing these pipes to ensure a reliable supply of water for residents and businesses in the community.
