In pipes, you need to connect a pipeline from the water supply tank to every house. You as the plumber must buy pieces of pipe from the pipe factory, carry them to where they should connect and put them in place. If you connect all the pipes properly, there will be no leaks when you turn on the water. The object is to use as little pipe as possible spend as little money as possible yet still connect every house. You have a limited amount of resources available.
