FLUSHER II is a redesign of the proven HYDRAPULSE Flusher Gate launched by Aussie Trenchless in 2015 to keep those problem sewers clean. FLUSHER II is an innovative gate device that pulses the flow of the sewer to minimise the build-up of fats, oil and grease (FOG) and debris, thus reducing ongoing maintenance costs by removing the need for costly, repetitive jetting and CCTV programs.

2021 sees the launch of FLUSHER II into the Australian market, which delivers a passive sewer clean with additional environmental, safety and customer benefits for asset owners. It also has the additional benefits of being easy to install and can be relocated to various problem areas.

Like HYDRAPULSE, the FLUSHER II is installed in sewer maintenance holes where the network is subject to sewer chokes as a result of FOG build up, silt and debris blockage due to sags in the line, and where solids are often deposited due to low flow conditions.

The unique design of the FLUSHER II provides an instantaneous snap opening and closing action which produces a wave pulse of wastewater to effectively flush and cleanse the downstream sewer. Upstream will encounter constant changes in the effluent level and flow, thus helping to prevent FOG, silt and debris from building up onto the sewer walls.

Installing FLUSHER II will allow the sewer to become a passive self-cleaning asset, requiring no power. The design is resistant to jamming and blocking, is inherently fail-safe during storm conditions, will remove surcharges caused by build ups, and needs minimal maintenance.

Asset owners will have less customer access complaints and no jet cleaning damage to the pipe internals. FLUSHER II is easy to install, can be monitored remotely and should be of interest to most water authorities, and city and regional councils that are responsible for the serviceability of the wastewater network.
