The StormTank Shield for stormwater pretreatment from Brentwood Industries reduces pollutant discharge through gross sediment removal and oil/water separation. By preventing floatables and oils from directly exiting the outlet pipe, flow length and settling time are increased, and cleaner water exits the outlet pipe. Its combination of pre-drilled mounting holes, handgrips and slim profile allow for ease of installation, while its access port and slim profile make it easy to clean and ensure that nothing obstructs the discharge. It is available in three sizes to provide application flexibility and has a built-in vent to prevent siphoning. 610/374-5109; www.brentwoodindustries.com.
