27 NO COMPROMISE Maintaining clean water ways is a constant challenge for Blue Mountains City Council, located about 100km west of Sydney, where 70 per cent of its 1433 square kilometres is inscribed on the UNESCO World Heritage Area Listing. Polluted stormwater is frequently a threat to the area’s unique fora and fauna. To counter this threat, the council uses a range of gross pollutant traps (GPTs) made by Baramy Engineering, which is headquartered in the municipal capital of Katoomba. Baramy Engineering was established in 1995 when Design Principal, Peter Bennett, felt he could improve upon existing GPTs used at the time by various government bodies. A long-term resident of the Blue Mountains, Bennett was also worried about water systems feeding into Warragamba Dam and surrounding national park. If compromised, Bennett said, these water ways could car ry pollutants downstream, damaging entire ecosystems. During high-fow water events, such as storms, traditional wet-sump solutions capture waste and suspend it in water. However, that waste soon becomes waterlogged, sinks to the bottom of @ CONTINUE THE CONVERSATION Have your say on this story. Visit http://goo. gl/rDccmu to comment on this article. TRAPPING POLLUTANTS IN A WORLD HERITAGE AREA Torrential stormwater can wreak havoc on sensitive ecosystems if gross pollutants and sediments are not tightly controlled. Here is one innovative solution helping conserve the New South Wales World Heritage Area-listed Blue Mountains. Custom-designed dual vane Baramy trap prevented approximately 55 tonnes of sediment from travelling over the Katoomba Falls.
