Catchment basin for use in a recirculating shower system

Abstract

The disclosure is directed at a catchment basin for use in a recirculating shower. The catchment basin includes a recirculation pool area for collecting shower water and a drain area. A divider wall separates the recirculation pool area and the drain area. The recirculation pool area is at a higher elevation than the drain area such that the collected shower water travels from the recirculation pool area to the drain area.

What is claimed: 
     
         1 . A catchment basin for use in a recirculating shower comprising:
 a recirculation pool area for collecting shower water;   a drain area; and   a divider wall separating the recirculation pool area and the drain area;   wherein the recirculation pool area is at a higher elevation than the drain area such that the collected shower water travels from the recirculation pool area to the drain area.   
     
     
         2 . The catchment basin of  claim 1  wherein the divider wall comprises a slot for receiving a drain plug. 
     
     
         3 . The catchment basin of  claim 2  further comprising a drain plug for installation within the slot. 
     
     
         4 . The catchment basin of  claim 3  wherein the drain plug comprises an orifice allowing for collected shower water to pass through the drain plug when the drain plug is installed in the slot. 
     
     
         5 . The catchment basin of  claim 1  wherein the divider wall comprising a spillway. 
     
     
         6 . The catchment basin of  claim 5  wherein the spillway comprises a designed form factor for skimming soap suds from a surface of the collected shower water. 
     
     
         7 . The catchment basin of  claim 1  further comprising piping for connecting the drain area to a sewer system. 
     
     
         8 . The catchment basin of  claim 1  wherein a surface of the recirculation pool area is elevated with respect to a surface of the drain area. 
     
     
         9 . The catchment basin of  claim 1  further comprising a set of corrugated ridges on an exterior of the catchment basin. 
     
     
         10 . The catchment basin of  claim 1  further comprising a raised back portion for mounting of the catchment basin to a wall. 
     
     
         11 . A shower pan for a recirculating shower comprising:
 a catchment basin including:   a recirculation pool area for collecting shower water;   a drain area; and   a divider wall separating the recirculation pool area and the drain area;   wherein the recirculation pool area is at a higher elevation than the drain area such that the collected shower water travels from the recirculation pool area to the drain area.   
     
     
         12 . The catchment basin of  claim 11  wherein the divider wall comprises a slot for receiving a drain plug. 
     
     
         13 . The catchment basin of  claim 12  further comprising a drain plug for installation within the slot. 
     
     
         14 . The catchment basin of  claim 13  wherein the drain plug comprises an orifice allowing for collected shower water to pass through the drain plug when the drain plug is installed in the slot. 
     
     
         15 . The catchment basin of  claim 11  wherein the divider wall comprising a spillway. 
     
     
         16 . The catchment basin of  claim 15  wherein the spillway comprises a designed form factor for skimming soap suds from a surface of the collected shower water. 
     
     
         17 . The catchment basin of  claim 11  further comprising piping for connecting the drain area to a sewer system. 
     
     
         18 . The catchment basin of  claim 11  wherein a surface of the recirculation pool area is elevated with respect to a surface of the drain area. 
     
     
         19 . The catchment basin of  claim 11  further comprising a set of corrugated ridges on an exterior of the catchment basin. 
     
     
         20 . The catchment basin of  claim 11  further comprising a raised back portion for mounting of the catchment basin to a wall.
