In some examples, the process can include introducing a water-rich product separated from a hydrocarbon production fluid that can include one or more hydrocarbons and water into a fluid storage apparatus. The water-rich product from the fluid storage apparatus can be introduced into a subterranean housing that can include a pressurizing apparatus at least partially disposed therein. The subterranean housing can be at least partially disposed under a surface of the earth. The pressurizing apparatus can have an inlet located within the subterranean housing and below the surface of the earth. The water-rich product from the subterranean housing can be introduced into the inlet of the pressurizing apparatus. A pressurized water-rich product from an outlet of the pressurizing apparatus can be introduced into an injection well. ## Claims ### Claim 1 A process for injecting into an injection well, comprising: introducing a water-rich product separated from a hydrocarbon production fluid comprising one or more hydrocarbons and water into a fluid storage apparatus;
