    Drywell Pretreatment Insert


    Drywell and/or stormwater manhole pretreatment device.


    In Central Oregon there are many direct inject or open grate drywells. These types of drywells have no pre-treatment prior to injecting collected sediments and contaminates to the subsurface contained in storm water.


    Without pretreatment sediments and debris flow directly into the drywell through a grated lid causing an environmental hazard and can eventual make the drywell fail and cause flooding.  The TSP Drywell Insert contains the hydrocarbons/floating debris/oil and grime and sediments within the unit. 


    The TSP Drywell Insert is also a low cost retrofit for sites source controls to meet authorization by rule within the DEQ UIC Program.
