Further, the system may include a contact reservoir that allows the water and the chlorinating substance to combine. In this way, the chlorinating substance is drawn only when needed, but is given the opportunity to achieve time in solution with the untreated water. As a result, bacteria in untreated water may be dispatched, while other organic substances in the untreated water are given the opportunity to settle to the bottom of the contact reservoir. A static mixer may be used to mix the chlorinating substance and the untreated water prior to entering the contact reservoir and/or while in the contact reservoir. ## Claims ### Claim 1 A system comprising: a unit of piping configured to connect to a source of untreated water, wherein the untreated water is pressurized;
