The ACU-TIP tipping bucket is a sediment flushing system designed to remove settled debris from reservoir floors, such as stormwater or CSO retention tanks and sanitary equalization tanks. The system operates by releasing a torrent of fresh water stored in the tipping bucket. The resulting flushing wave progresses down the entire length of the flushway pushing the settled debris ahead of it. The re-suspended debris is then carried by the flush water to the treatment plant for disposal.
The ACU-TIP has several advantages over other types of sediment flushing systems. Firstly, because the system uses fresh water as the source of the flushing wave, one is assured that no additional debris will be introduced in the tank as the flushing operation is completed. Secondly, in the rare event that additional flushes are required, the tipping bucket’s filling system can be easily re-activated and the flushing sequence repeated. Thirdly, because the ACU-TIP tipping bucket is suspended over the tank and never comes in contact with debris, the need for maintenance is reduced assuring economical and trouble free operation. Finally, the ACU-TIP can be installed in new tanks or easily retrofitted in existing storage tanks.
