CONTROLLING FATS, OILS AND GREASES
IN SEWER PIPE NETWORKS
For many years, fats, oils and greases (FOG) have been a significant problem in sewer networks resulting in surcharge incidents to stakeholders if left unchecked. These incidents are generally confined to areas where there are high concentrations of fastfood outlets and restaurants.
Upstream will encounter the most significant increase in velocity, and this increase can be varied by adjusting the FLUSHER II to ensure the right effect has been achieved. FOG surcharge conditions result in loss of hydraulic performance, and the following diagram shows extracts from a Hydraulic Assessment undertaken by Atkins Global demonstrating the benefits of installing the FLUSHER II.

LUSHER II is a simple solution designed to maintain the serviceability of underperforming sewer catchments. FLUSHER II attenuates effluent for a short period and at a predetermined hydraulic head, an automated gate releases a high-volume, low-pressure column of effluent through the catchment network, scouring and mobilising sediment downstream to prevent future silt buildups and FOG blockages.
FLUSHER II A passive gate device for controlling and maximising hydraulic flow in sewers •
Reduces operational costs – No more water jet sewer cleaning – No more Silt & Debris removal – Less surcharge & blockages
•
Installed in Maintenance Holes – Easy to install – Easy to maintain – For DN150 to DN450 sewer pipes Resistant to rag jamming and blocking Inherently “fail safe” during storms Data Logger and Telemetry Module – Know what’s happening and when
