1. A shower water recycling system for toilet flushing comprising: a parallelepiped storage tank for use in conjunction with a shower, the storage tank comprising: a centrally draining top surface;a first side;a second side;a third side;a fourth side;a base;an interior cavity disposed between the top surface, the first side, the second side, the third side, the fourth side, and the base;an upper wall disposed perimetrically around the top surface;a drainage hole centrally disposed within the top surface;a rotatable plug sealingly disposed in the drainage hole, the rotatable plug comprising: a circular body having an upper surface and a lower surface;a raised ridge diametrically disposed across the upper surface;a hole disposed through the circular body;a cylindrical drainage collar disposed upon the lower surface, the drainage collar disposed circumferentially around the hole;a water pipe inlet disposed in the first side;a float valve disposed within the interior cavity, the float valve in operational communication with the water inlet;an outlet disposed in the first side, the outlet in operational communication with an extant toilet cistern;a pump disposed on the outlet;a filter disposed between the outlet and the pump;a flush drainage centrally disposed in the base, the flush drainage plumbed with an extant wastewater pluming system;a drainage pipe vertically disposed between the drainage hole and the flush drainage;a flush valve disposed on the drainage pipe proximal to the base;a moveable flush arm in operational communication with the flush valve, the flush arm slidingly moveable between a first position and a second position to alternately close and open the flush valve;a knob disposed on the flush arm, the knob disposed exteriorly upon the storage tank; wherein the rotatable plug drains water into the storage tank when in the first drainage position, and into the drainage pipe when in the second drainage position, the float valve activates the water inlet to inflow water from extent plumbing into the interior cavity when a water volume reaches a minimum volume, the flush arm drains the storage tank through the central drainage when moved to the second position, and the pump pressurizes water from the storage tank, through the outlet, into extant plumbing to an extant toilet cistern. 2. The shower water recycling system for toilet flushing of claim 1 wherein the drainage collar alternately engages and disengages with the drainage pipe upper end when the rotatable plug is moved between the first drain position and the second drain position. 3. The shower water recycling system for toilet flushing of claim 2 wherein the drainage pipe upper end is exposed within the interior cavity when the rotatable plug is moved to the first position and the drainage collar disengages with the drainage pipe upper end, whereby water drains through the drainage pipe upper end when a water volume in the storage tank exceeds a maximum volume. 4. The shower water recycling system for toilet flushing of claim 3 wherein the pump pumps water from the storage tank through extant plumbing to an extant toilet cistern, said pump activated when pressure in the extant plumbing drops, said pressure lowered when the toilet is flushed and the cistern emptied. 5. The shower water recycling system for toilet flushing of claim 4 wherein the pump deactivates when the pressure in the extant plumbing between the pump and the extant toilet reaches a determined pressure. 6. The shower water recycling system for toilet flushing of claim 5 wherein the rotatable plug raised ridge is disposed within a plane accordant with the storage tank top surface. 7. A shower water recycling system for toilet flushing comprising: a parallelepiped storage tank for use with a shower, the storage tank comprising: a centrally draining top surface;a first side;a second side;a third side;a fourth side;a base;an interior cavity disposed between the top surface, the first side, the second side, the third side, the fourth side, and the base;an upper wall disposed perimetrically around the top surface;a drainage hole centrally disposed within the top surface;a rotatable plug sealingly disposed in the drainage hole, the rotatable plug comprising: a circular body having an upper surface and a lower surface;a raised ridge diametrically disposed across the upper surface;a hole disposed through the circular body;a cylindrical drainage collar vertically disposed upon the lower surface, the drainage collar disposed circumferentially around the hole; wherein the plug is rotatable between a first drain position and a second drain position; a water pipe inlet disposed in the first side;a float valve disposed within the interior cavity, the float valve in operational communication with the water inlet, the float valve comprising: a valve;a lever arm in operational communication with the valve;a float body disposed upon the lever arm; wherein the float body moves the lever arm between a minimum position and a maximum position to regulate an inflow of water into the storage tank above a minimum volume whereby a reserve volume is maintained; an outlet disposed in the first side, said outlet plumbed with an extant toilet cistern;a pump disposed on the outlet;a filter disposed between the outlet and the pump; wherein the pump pumps water from the storage tank to the extant toilet cistern when the cistern is emptied by use of said toilet; a flush drainage disposed in the base, the flush drainage interconnected with an extant wastewater plumbing system;a drainage pipe vertically disposed between the drainage hole and the flush drainage, the drainage pipe having an upper end disposed beneath the rotatable plug; wherein the drainage collar alternately engages and disengages with the drainage pipe upper end when the rotatable plug is moved between the first drain position and the second drain position; wherein the upper end is exposed within the interior cavity when the rotatable plug is moved to the second position, whereby a water volume within the storage tank is maintained up to a maximum volume; a flush valve disposed on the drainage pipe proximal to the base;a moveable flush arm in operational communication with the flush valve, the flush arm slidingly moveable between a first position and a second position to alternately close and open the flush valve;a knob disposed on the flush arm, the knob disposed exteriorly upon the storage tank; wherein the knob alternately opens and closes the valve to drain the storage tank when the flush arm is moved between the first position and the second position; wherein the drainage collar sealingly engages with the drainage pipe upper end when the rotatable plug is moved to the second drain position, and the drainage collar disengages with the drainage pipe upper end when the rotatable plug is moved to the first drain position; wherein water from an extant shower drains alternately into the interior cavity and the drainage pipe; wherein the float valve activates the water inlet to inflow water from extent plumbing into the interior cavity and the pump pumps water through extant plumbing to an extant toilet cistern; whereby a water volume is maintained between a maximum volume and a minimum volume within the storage tank.
