System and method for showering with fixed parameter water usage

Abstract

A showering system comprising a first tank, a first and second pump, a water heater, a shower head, a shower base and a valve; wherein water for a shower is stored in the first tank from which it is pumped via the first pump through the water heater to the shower head whence from the water falls to the shower base and passes to the valve from which the water is either discharged to a sewer or pumped via the second pump back to the first tank.

1 . A showering system comprising a first tank, a first and second pump, a water heater, a shower head, a shower base and a valve; wherein water for a shower is stored in the first tank from which it is pumped via the first pump through the water heater to the shower head whence from the water falls to the shower base and passes to the valve from which the water is either discharged to a sewer or pumped via the second pump back to the first tank. 
     
     
         2 . A showering system as in  claim 1 , wherein a shower is conducted in a first, second and third stage; wherein during the first stage the water is returned from the valve to the first tank via the second pump; during the second stage the water is discharged from the valve to the sewer; and during the third stage the water is returned from the valve to the first tank via the second pump. 
     
     
         3 . A showering system as in  claim 2 , wherein the shower transitions from the second stage to the third stage when a preset volume of water has been pumped from the first tank. 
     
     
         4 . A showering system as in  claim 2 , wherein the shower transitions from the first stage to the second stage in response to an action from a user of the shower. 
     
     
         5 . A showering system as in  claim 2 , wherein the shower transitions from the first stage to the second stage when the water temperature reaches a preset level. 
     
     
         6 . A showering system as in  claim 2 , wherein the shower transitions from the first stage to the second stage when a preset time has elapsed 
     
     
         7 . A showering system as in  claim 1 , further comprising a third pump and a second tank wherein at the completion of the shower the remaining water in the first tank is pumped to the second tank via the third pump. 
     
     
         8 . A showering system as in  claim 7 , further comprising a third tank in which water for the shower is stored; wherein water to the first pump can come from either the first tank or the third tank. 
     
     
         9 . A showering system as in  claim 8 , wherein water may be taken simultaneously from the first tank by the third pump and from the third tank by the first pump 
     
     
         10 . A showering system as in  claim 1 , wherein the water returned from the valve to the first tank is sterilized. 
     
     
         11 . A method for showering comprising the steps of; filling a first tank with a preset volume of water; pumping the water to a shower head, collecting the water from a shower base and returning the water to the first tank; pumping the water to a shower head, collecting the water from the shower base and discharging the water to a drain; and, pumping the water to a shower head, collecting the water from a shower base and returning the water to the first tank. 
     
     
         12 . A method of showering as in  claim 11 , comprising a further step of pumping the water from the first tank to a second tank for recycling.
