In this article, we cover commercial and residential stormwater assets such as filter cartridges which are situated within OSD tanks. And drainage pit baskets which are catchment cages that are inserted into new and existing stormwater pits. To prevent trash and large debris entering the pit and subsequent waterways.

Stormwater Filter cartridges

Most stormwater management on residential and commercial facilities across NSW use filter cartridges in their onsite detention tanks. Common brands of filter cartridges and filtration systems include the StormFilter cartridges manufactured by Ocean Protect. In short, cartridge filtration systems clean stormwater as it passes through the cartridges. This removes pollutants to meet EPA and council regulatory requirements.

These pit baskets can be installed within new and existing stormwater pits. They are designed to intercept stormwater as it enters the stormwater pits with diversion panels.
