Liquid
: "My new LEGO IDEAS design "The Urban Water Cycle" illustrates the journey of water from its source to the city and back into nature - also featuring some above-ground pumps. The set has 7 minifigures including a pump mechanic. It needs 10K supporters for the chance to become an official LEGO set."
