Water flushing system providing treated discharge

Abstract

A water flushing system for a pressurized subterranean water distribution system includes an inlet conduit for receiving pressurized water from the subterranean water distribution system; an outlet fluidly connected to the inlet conduit for discharging pressurized water in the inlet conduit downwardly towards a drain; and a control valve for controlling the flow of pressurized water in the inlet conduit. The water flushing system further includes one or more of the following features: a freeze protection assembly, a detachable coupling system, a dechlorination system, and a backflow prevention system.

1 . A water flushing system comprising: 
 a flow controlled passage for pressurized water having an inlet adapted for fluid connection to a pressurized water distribution system;    a flow control valve disposed along the flow controlled passage for selectively permitting and prohibiting the flow of pressurized water through the flow controlled passage and into a discharge conduit, the discharge conduit having an outlet for discharge of the pressurized water;    first piping for routing at least a portion of the pressurized flow downstream of the flow control valve to a treatment container, the treatment container holding at least one treatment substance, wherein the water in the first piping is exposed to the water treatment substance, whereby the water becomes treated; and    second piping for routing the treated water to the discharge conduit for discharge, whereby the treated water is mixed with and treats the untreated pressurized water in the routing conduit.    
     
     
         2 . The water flushing system of  claim 1  wherein the water treatment substance is at least one of minerals, vitamins, purification agents, bio-growth inhibitors and dechlorination agents.  
     
     
         3 . The water flushing system of  claim 1  wherein the water treatment substance includes at least one dechlorination tablet.  
     
     
         4 . The water flushing system of  claim 1  wherein the water treatment substance is one of sodium sulfite and ascorbic acid.  
     
     
         5 . A water flushing system of  claim 1  further including a valve operatively associated with the first piping for selectively permitting and restricting the flow of water into the water treatment container.  
     
     
         6 . The water flushing system of  claim 1  further including: 
 programmable electronic control circuitry for controlling the flow of pressurized water through the flow controlled passage by activating and deactivating the flow control valve, the system including a programmable microprocessor system for storing instructions for activating and deactivating the flow control valve; and    at least one programming interface operatively connected to the microprocessor system for inputting electronic information to be stored and processed in the microprocessor system for activating and deactivating the flow control valve.    
     
     
         7 . A water treatment method comprising: 
 providing a pressurized water distribution system and a water flushing system receiving pressurized water from the water distribution system, the flushing system including a flow controlled passage for pressurized water having an inlet adapted for fluid connection to the pressurized water distribution system, and a flow control valve disposed along the flow controlled passage for selectively permitting and prohibiting the flow of pressurized water through the flow controlled passage and into a discharge conduit for discharge of the pressurized flow;    activating the flow control valve so as to permit the flow of pressurized water through the flow controlled passage and into the discharge conduit;    diverting at least a portion of the pressurized flow;    exposing the diverted pressurized flow to a water treatment substance; and    routing the treated flow to the discharge conduit for mixing with untreated flow from the flow controlled passage and discharge.    
     
     
         8 . The water treatment method of  claim 7  wherein the water treatment substance is at least one of minerals, vitamins, purification agents, bio-growth inhibitors and dechlorination agents.  
     
     
         9 . The water treatment method of  claim 7  wherein the water treatment substance includes dechlorination tablets.  
     
     
         10 . The water treatment method of  claim 7  wherein the water treatment substance is one of sodium sulfite and ascorbic acid.  
     
     
         11 . The water treatment method of  claim 7  wherein the step of activating the flow control valve is performed automatically by programmable electronic control circuitry.
