Golf course green storm water filter

Abstract

A method of making a golf course green drainage system and the system made from the process which includes forming a drainage system field in a golf course green and coupling a drain pipe to the drain field for channeling water collected from the drain field. The process includes selecting a filter system having an inlet and a discharge for filtering water from the golf course green drainage field and placing the selected filter underground remotely from the golf course green and connecting the drain pipe thereto. The filter system discharge is connected to a retention pond so that water collected on a golf course green drainage field is filtered prior to being fed into the retention pond. The process includes selecting a filter having a housing and a hydrocarbon absorbent filter medium therein having a filter screen covering over the hydrocarbon absorbent medium and having a water deflector adjacent the inlet.

We claim:  
     
         1 . A method of making a golf course green drainage system comprising: 
 forming a drainage system field in a golf course green;    coupling a drain pipe to said drainage system field for channeling water collected from said drain field;    selecting a filter system having an inlet and a discharge for filtering water from said golf course green drainage field;    placing said selected filter system underground remote from said golf course green;    connecting said drain pipe to said remote underground filter system; and    discharging said selected filter system water from said filter system discharge into a retention pond; whereby water collected in a golf course green drainage field is filtered prior to being fed into a retention pond.    
     
     
         2 . The method of making a golf course green drainage system in accordance with  claim 1  including the step of connecting a drain pipe from said filter system discharge to a retention pond.  
     
     
         3 . The method of making a golf course green drainage system in accordance with  claim 2  in which the step of selecting a filter system includes selecting a filter system having a housing having a hydrocarbon absorbent filter medium therein.  
     
     
         4 . The method of making a golf course green drainage system in accordance with  claim 3  in which the step of selecting a filter system includes selecting a filter system having a housing a screen filter covering said hydrocarbon absorbent filter medium.  
     
     
         5 . The method of making a golf course green drainage system in accordance with  claim 4  in which the step of selecting a filter system includes selecting a filter system having a housing having a water deflector adjacent the inlet thereto.  
     
     
         6 . The method of making a golf course green drainage system in accordance with  claim 2  in which the step of forming a drain field in a golf course green includes placing a series of pipes in a parallel layout each positioned to direct water into a collection pipe and into said drain pipe.  
     
     
         7 . The method of making a golf course green drainage system in accordance with  claim 6  in which the step of forming a drain field in a golf course green placing of pipes in a parallel layout included placing a series of parallel clay pipes in the golf course green.  
     
     
         8 . A golf course green drainage system comprising: 
 a golf course water drainage field located in a golf course green;    a drain pipe coupled to said golf course water drainage field for draining water therefrom;    a filter system having an inlet and an outlet and being connected to said drain pipe for receiving and filtering water from said golf course green, said filter system having a hydrocarbon absorbent filter medium therein positioned for removing hydrocarbons from said water passing therethrough; and    said filter system discharge being connected to a channel into a water retention pond; whereby a golf course green can dispose of drain water that has been filtered and had oil removed therefrom.    
     
     
         9 . The golf course green drainage system of FIG. 8 in which said hydrocarbon filter medium includes a cellulose fiber material therein.  
     
     
         10 . The golf course green drainage system of FIG. 8 in which said hydrocarbon filter medium includes a waste cellulose fiber material from a papermill therein.  
     
     
         11 . The golf course green drainage system of FIG. 8 in which said filter system includes a housing having a water deflector therein located adjacent said inlet.  
     
     
         12 . The golf course green drainage system of FIG. 11 in which said filter system includes a housing having a screen filter therein covering said hydrocarbon filter medium therein.  
     
     
         13 . The golf course green drainage system of FIG. 8 in which said golf course water drainage field located in a golf course green includes a plurality of parallel drain pipes located beneath said golf course green.  
     
     
         14 . The golf course green drainage system of FIG. 8 in which said plurality of parallel drain pipes are clay pipes.
