Stormwater filtration solution

Passes the test for council, power station

As far back as 2006, a large council depot in South Australia had an issue with silt and hydrocarbons entering its many drains in its large sealed yard. After looking through a few options, it settled on the Drain King by Spilldoktor as the best solution for the application.

Drain King is a stainless steel structure with a removable geofabric filter attached. The ease of fitting and serviceability of these units is a good feature. The units can be removed very simply and the geofabric filter washed or replaced as often as required.

A design feature of the units is the integrated overflow holes on each side, which is a safety measure; ie, should the geofabric filter be restricted, in the instance of a sudden downpour, the drain will not block.

Another key benefit of the units is the integrated floating pillow which acts as a hydrocarbon filter to collect run-off oil and diesel from plant and vehicles. This is a problem which has been around forever but has historically been hard to manage at the ‘front line’ or first point of entry to the stormwater system.

Approximately 20 drains at the council depot were fitted with this device in 2006 and the amount of pollutants stopped by the Drain King in the years since installation has been proof that the decision was a good one.

In late 2009, designers of a new substation in SA selected Drain King as the preferred means of controlling stormwater pollution on a sensitive site. One of the key factors was cost effectiveness, the units cost less than $1000 and perform a similar role (albeit on a smaller scale) to that of a Gross Pollutant Trap. The units were custom made to fit several drains and will offer sediment and hydrocarbon control well into the future.
