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 pump, coupled to a unit of piping within a system of piping, configured to inject a chlorinating substance into the unit of piping when remotely triggered; a contact reservoir, coupled to the unit of piping, configured to receive raw water and the chlorinating substance, and to combine the raw water and the chlorinating substance to produce a solution therefrom; and a flow valve, disposed within the system of piping and electronically coupled to the pump, configured to: sense a flow of water through the system of piping; and in response to sensing the flow, generate and transmit to the pump an electronic control signal by way of an electronic triggering line that remotely triggers the pump to inject the chlorinating substance into the unit of piping. ### Claim 2 (depends on 1) The system of claim 1, further comprising: a de-chlorinator configured to receive the solution from the contact reservoir, and configured to separate the chlorinating substance from the solution to provide treated water. ### Claim 3 (depends on 2) The system of claim 2, wherein the flow valve is coupled to the de-chlorinator. ### Claim 4 (depends on 2) The system of claim 2, wherein the raw water received by the contact reservoir is drawn from an untreated water supply. ### Claim 5 (depends on 1) The system of claim 1, wherein the pump is further configured to draw the chlorinating substance from a chlorinating substance reservoir. ### Claim 6 (depends on 1) The system of claim 1, further comprising: a static mixer configured to combine the raw water and the chlorinating substance prior to the raw water entering the contact reservoir. ### Claim 7 (depends on 6) The system of claim 6, wherein the static mixer is integrated with the contact reservoir. ### Claim 8 (depends on 7) The system of claim 7, wherein the pump is also integrated with the contact reservoir. ### Claim 9 (depends on 1) The system of claim 1, further comprising: a static mixer located within the contact reservoir and configured to combine the raw water and the chlorinating substance while the raw water is in the contact reservoir, and wherein the contact reservoir is a tank containing a centrifuge-like spin-down operation that separates organic substances from the solution. ### Claim 10 (depends on 1) The system of claim 1, wherein the pump is connected by the unit of piping to the contact reservoir, and wherein the contact reservoir is connected by a second unit of piping to the flow valve. ### Claim 11 (depends on 10) The system of claim 10, further comprising: a flow head coupled to the contact reservoir, wherein the flow head comprises an input port and an output port, wherein the input port is coupled to the unit of piping, and wherein the output port is coupled to the second unit of piping. ### Claim 12 (depends on 1) The system of claim 1, wherein the chlorinating substance is hydrogen peroxide. ### Claim 13 (depends on 1) The system of claim 1, wherein the chlorinating substance is an oxidizing agent. ### Claim 14 (depends on 1) The system of claim 1, wherein the flow valve is configured to sense the flow by detecting a change in pressure of the solution at the flow valve. ### Claim 15 A method comprising: sensing, by a flow valve, a flow of water through a system of piping; in response to sensing the flow, generating and transmitting to a pump an electronic control signal by way of an electronic triggering line that remotely triggers the pump to inject a chlorinating substance into a unit of piping, wherein the unit of piping is disposed within the system of piping; receiving, by a contact reservoir, raw water and the chlorinating substance from the unit of piping; and combining, by the contact reservoir, the raw water and chlorinating substance to produce a solution therefrom. ### Claim 16 (depends on 15) The method of claim 15, further comprising: receiving the solution from the contact reservoir; and separating the chlorinating substance from the solution. ### Claim 17 (depends on 15) The method of claim 15, wherein a static mixer is configured to combine the raw water and the chlorinating substance. ### Claim 18 (depends on 17) The method of claim 17, wherein the static mixer is integrated with the contact reservoir. ### Claim 19 (depends on 15) The method of claim 15, wherein the pump is connected by a first unit of piping to the contact reservoir, and wherein the contact reservoir is connected by a second unit of piping to the flow valve. ### Claim 20 (depends on 2) The system of claim 2, wherein the flow valve is positioned downstream from the de-chlorinator, and wherein the treated water passes through the flow valve.
