Drainage treatment system

Abstract

A drainage treatment system for minimizing debris entering a drainage system is described herein, the system including a support housing supportingly received in the drainage system downstream of an opening thereof. The support housing includes a first drainage means for allowing liquid to flow therethrough. The system also includes a first insert for collecting debris, the first insert having a second drainage means for allowing liquid to flow therethrough while preventing the flow through of debris. The first insert is removably supported within the housing such that when in place, the first and second drainage means align, permitting liquid to pass through the drainage treatment system. In use, debris collects in the system and is removed therefrom by removing the first insert from the support housing.

I claim: 
     
         1 . A drainage treatment system for minimizing debris entering a drainage system, comprising:
 a support housing adapted to be supportingly received in the drainage system downstream of an opening of the drainage system, the support housing including a first drainage means for allowing liquid to flow therethrough,   a first insert for collecting debris, the first insert including a second drainage means for allowing liquid to flow therethrough while preventing the flow through of debris, the first insert being removably supported within the housing such that when in place, the first and second drainage means allow liquid to pass through the drainage treatment system,   wherein the debris collected in the drainage treatment system is removed therefrom by removing the first insert from the support housing.   
     
     
         2 . The system of  claim 1 , further comprising a diffuser locatable in the first insert. 
     
     
         3 . The system of  claim 2 , wherein the diffuser comprises openings therein to allow the liquid and debris to pass therethrough. 
     
     
         4 . The system of  claim 1 , wherein the support housing further includes a first housing for receiving the first insert. 
     
     
         5 . The system of  claim 4 , wherein the first housing is tapered inwardly such that an opening thereof is larger than the bottom thereof. 
     
     
         6 . The system of  claim 4 , wherein the first housing supports one or more fixings to which the first insert is fixed, the fixings being in the form of brackets located on the inner surface of the first housing. 
     
     
         7 . The system of  claim 4 , wherein the entire first housing provides the first drainage means. 
     
     
         8 . The system of  claim 1 , further comprising a securing means to removably support the drainage treatment system relative to the drainage system. 
     
     
         9 . The system of  claim 8 , wherein the securing means includes two or more arms extending upwardly from the first housing. 
     
     
         10 . The system of  claim 9 , wherein a distal end of each arm has an outwardly extending projection adapted to engage a surface of the drainage system. 
     
     
         11 . The system of  claim 8 , wherein the securing means is provided by the top portion of the first housing which extends outwardly so as to be adapted to engage a surface upon which the grate is supported when the grate is in place. 
     
     
         12 . The system of  claim 4 , wherein the support housing further includes a second housing. 
     
     
         13 . The system of  claim 1 , wherein the support housing includes
 a first housing for receiving the first insert, and   a second housing located below the first housing such that in use it is downstream therefrom.   
     
     
         14 . The system of  claim 13 , wherein the second housing has a third drainage means. 
     
     
         15 . The system of  claim 14 , wherein the entire second housing provides the third drainage means. 
     
     
         16 . The system of  claim 1 , wherein the entire first insert provides the second drainage means. 
     
     
         17 . The system of  claim 1 , further comprising at least one flow diverter for directing flow into the first insert. 
     
     
         18 . A drainage treatment system for minimizing debris accumulating in a drainage system, comprising:
 a support housing supportingly received in the drainage system and including a first drainage means for allowing liquid to flow therethrough,   a first insert removably supported within the support housing for collecting debris, the first insert including a second drainage means for allowing liquid to flow therethrough while preventing the flow through of debris, and   a diffuser located in the first insert to minimize debris collected in the first insert from being ejected therefrom.   
     
     
         19 . The system of  claim 18 , further comprising at least one flow diverter for directing flow into the first insert.
