Stormwater is not cleaned as it is perceived by many people, particularly in cities where the commercial, traffic and domestic activities increase stormwater pollution. Discharge of untreated stormwater pollutes the receiving waterways. CBA Consultants Ltd designs treatment devices and systems to treat urban stormwater. Some of the stormwater quality devices that CBA Consultants Ltd has designed include stormwater quality ponds, rain gardens, scoria trenches, sand filters, Upflo and stormfilters systems.
