Introduction
Tipping bucket systems provide automated sediment removal from reservoir floors in stormwater retention tanks, CSO (Combined Sewer Overflow) facilities, and sanitary equalization tanks. Stainless steel 316 bearings enable reliable operation in continuous water exposure.
System Operation
The tipping bucket sediment flushing system operates by releasing a stored torrent of fresh water from the bucket. As the bucket fills to capacity, it tips forward, unleashing a flushing wave that progresses down the entire flushway length. This wave pushes settled debris and sediment ahead of it, keeping tank floors clean. The re-suspended sediment is then carried by the flush water to the treatment plant for proper disposal.
Bearing Requirements
Continuous Water Exposure: Bearings are submerged or constantly splashed with water. Pivot Load: Supporting the weight of the filled bucket plus dynamic tipping forces. Corrosion Resistance: Stormwater may contain salt, chemicals, and contaminants. Maintenance Access: Often installed in confined spaces making maintenance difficult. Reliability: Automated systems must operate without intervention.
Extreme Bearing Solution
AISI 316 stainless steel construction provides complete corrosion resistance in water immersion. Robust bearing design handles the pivot loads and dynamic forces during tipping. Sealed design prevents water ingress despite continuous exposure. Maintenance-free operation compatible with automated systems.
Application Benefits
- Automated sediment removal maintains tank capacity
- Prevents sediment buildup that reduces storage volume
- Eliminates manual cleaning requirements
- Uses any available water supply: potable, ground water, or treated effluent
- Reliable bearing performance in continuous water exposure
Key Technical Points
- AISI 316 grade essential for stormwater corrosion resistance
- Bearings must handle both static and dynamic tipping loads
- Sealed design prevents water ingress and sediment contamination
- Maintenance-free operation required for automated systems
