And finally, for the stormwater storage grate, the sizes may vary for application as shown in the charts above.SYSTEM COMPONENTSThe RainFilter is designed with the following components: MAINTENANCE Stainless-steel Basket Screen BMPs are typically designed to completely drain within HPDE Tank 24 to 48 hours after the completion of a storm event. Stormwater Storage Equipment as Required These BMPs are designed to mimic natural conditionsPiping by allowing water to soak into the ground and limitingthe release of stormwater to other pipes or bodies of water.
