Nestable catch basin assembly with removable debris trap

Abstract

A catch basin assembly for draining water into an underground drainage conduit through a riser includes a housing having an open top and a bottom including an outlet section configured for connection to the riser. A debris trap is removably installed in the housing so as to capture and retain particulate debris from water flowing into the housing through the top thereof, the debris trap having an apertured portion that allows water to flow from the debris trap to the outlet section. The housing has a tapered configuration, whereby two or more housings, with the debris traps removed therefrom, can be stacked in a nesting relationship.

1 . A catch basin assembly for draining water into an underground drainage conduit through a riser, the catch basin assembly comprising: 
 a housing having an open top and a bottom including an outlet section configured for connection to the riser; and    a debris trap removably installed in the housing so as to capture and retain particulate debris from water flowing into the housing through the top thereof, the debris trap having an apertured portion that allows water to flow from the debris trap to the outlet section.    
   
   
       2 . The catch basin assembly of  claim 1 , wherein the housing has a tapered configuration, whereby two or more housings, with the debris traps removed therefrom, can be stacked in a nesting relationship.  
   
   
       3 . The catch basin of  claim 1 , further comprising a cover with a grate section removably installed in the top of the housing.  
   
   
       4 . The catch basin of  claim 1 , wherein the debris trap comprises a bowl portion for collecting the debris, the bowl portion having an upper peripheral rim; and wherein the apertured portion comprises a circumferential array of apertures below the rim.  
   
   
       5 . A catch basin assembly for draining water into an underground drainage conduit through a riser, the catch basin assembly comprising: 
 a housing having an open top and a bottom including an outlet section configured for connection to the riser; and    debris trapping means, removably installed in the housing, for capturing and retaining particulate debris from water flowing into the housing through the top thereof, while allowing water to flow from the debris trapping means to the outlet section.    
   
   
       6 . The catch basin assembly of  claim 5 , wherein the debris trapping means comprises a debris retention portion, a water passage section surrounding the debris retention portion, and means for removably holding the debris trapping means in the housing.  
   
   
       7 . The catch basin assembly of  claim 6 , wherein the housing includes an annular shoulder between the open top thereof and the outlet section, and wherein the means for removably holding the debris trapping means in the housing includes a peripheral rim surrounding the water passage section, the rim being configured and dimensioned so as to be engageable with the shoulder.  
   
   
       8 . The catch basin of  claim 6 , wherein the debris retention portion comprises a bowl for collecting the debris, and wherein the water passage portion comprises an apertured portion circumferentially surrounding the bowl.  
   
   
       9 . The catch basin assembly of  claim 5 , wherein the housing has a tapered configuration, whereby two or more housings, with the debris trapping means removed therefrom, can be stacked in a nesting relationship.  
   
   
       10 . The catch basin of  claim 5 , further comprising a cover with a grate section removably installed in the top of the housing.  
   
   
       11 . A catch basin assembly for draining water into an underground drainage conduit through a riser, the catch basin assembly comprising: 
 a housing having an open top and a bottom including an outlet section configured for connection to the riser; and    a debris trap removably installed in the housing so as to capture and retain particulate debris from water flowing into the housing through the top thereof, the debris trap having an apertured portion that allows water to flow from the debris trap to the outlet section;    wherein the housing has a tapered configuration, whereby two or more housings, with the debris traps removed therefrom, can be stacked in a nesting relationship.    
   
   
       12 . The catch basin of  claim 11 , wherein the debris trap comprises a bowl portion for collecting the debris, the bowl portion having an upper peripheral rim; and wherein the apertured portion comprises a circumferential array of apertures below the rim.  
   
   
       13 . The catch basin assembly of  claim 11 , wherein the housing includes an annular shoulder between the open top thereof and the outlet section, and wherein the peripheral rim of the debris trap is configured and dimensioned so as to be engageable with the shoulder.  
   
   
       14 . The catch basin assembly of  claim 11 , further comprising a cover with a grate section removably installed in the top of the housing.
