The perfect stormwater management product has yet to be invented. Even under optimal conditions, no product is going to capture 100% of pollutants. For those oils and gases that make it past the ultra-drain guard and into the catch basin below, weve added an ultra-archaea boom. The oil-eating microbes housed in this boom activate when exposed to water. Once activated they consume the hydrocarbons in the water and leave behind only harmless, natural byproducts. The ultra-drain guard, archaea boom model provides protection above and below the storm drain.
