Stormceptor® Maintenance Guidelines
No entry into the unit is required for routine maintenance of the Stormceptor® unit. The fiberglass insert has been designed as a platform for authorized personnel, in the event that an obstruction needs to be removed, drain flushing needs to be performed, or camera surveys of the stormline are required.
Rinker Materials generally recommends annual maintenance be performed or when the sediment volume in the unit reaches 15 percent of the Stormceptor® total storage. In the event of any hazardous spill, Rinker Materials recommends maintenance be performed immediately. Maintenance should be performed by a licensed liquid waste hauler.
Maintenance frequency varies depending on the application and will be site specific. Rinker Materials recommend quarterly inspections during the first year of installation to accurately establish a maintenance schedule. Development of a routine maintenance interval helps ensure a regular maintenance schedule is followed. Although the frequency of maintenance will depend on site conditions, it is estimated that annual maintenance will be required for most applications; annual maintenance is a routine occurrence which is easy to plan for and remember.
Oil is removed through the 6” inspection/oil port and sediment is removed through the 24” diameter outlet riser pipe. Alternatively, oil could be removed from the 24” opening if water is removed from the lower chamber, lowering the oil level below the drop pipe. For the STC 450i maintenance is performed through the 12” inlet drop pipe. The inlet drop pipe has a tapered insert connected to a handle. After removing the handle, remove oil and sediment from the 12-inch diameter inlet drop pipe.
Requirements for the disposal from Stormceptor® are similar to that of any other Best Management Practice. Local guidelines should be consulted prior to disposal of the separator contents.
In most areas the sediment, once dewatered, can be disposed of in a sanitary landfill. It is not anticipated that the sediment would be classified as hazardous waste. In some areas, mixing the water with the sediment will create a slurry that can be discharged into a trunk sanitary sewer. In all disposal options, approval from the disposal facility operator/agency is required. Petroleum waste products collected in Stormceptor® (oil/chemical/fuel spills) should be removed by a licensed waste management company.
