A rocket that uses water as a propellant to reach space is possible, many rockets are fueled by a mix of hydrogen and oxygen which when burnt produces a exhaust product of water, which is the reaction mass moving the rocket forward. To start, you'll need a team of people a large amount of funding. First, construct and design a rocket engine using hydrogen as a fuel and oxygen as an oxidizer. You'll likely want to follow an existing design, such as the gas generator cycle design, which incorporates three turbomachinery components, a fuel pump, an oxidizer pump, and a turbine. Then, once you have the rocket engine, simply build the rest of the rocket, making sure not to launch this rocket without first contacting the relevant airspace authorities.
