‘The Tipper’ is a percolation device designed and developed in conjunction with Trinity College Dublin to boost the flow of effluent from the septic tank through the length of the percolation pipe. European patent No. 2321479.
Effluent from a septic tank trickles under gravity into a percolation area; these low flows have several disadvantages:
- When distributed amongst several trenches the flow is further divided and reduced which compromises even distribution.
- Flows tend not to travel down the length of a percolation pipe, tending to fall through the first few perforations.
- It can cause settlement of unwanted solids and the development of bio‐film within the pipe. These issues often result in the failure of the percolation system.
- Trinity College Dublin has developed this device to counteract the problems associated with low flow discharges from septic tanks.
- The device collects large volumes of water and distributes this flow evenly under gravity between each trench.
- This ensures adequate flow, preventing solid settlement and bio‐film build‐up within the pipe.
- The device has been proven in extensive field trials with real on‐site wastewater effluent to give even distribution amongst several trenches and also flow along the length of each trench.
