Pumping station
The following table specifies the cable’s recommended length (L) of the On/Off
float for a maximum distance of 48 m (160') between the pumping station and
the treatment system. It presents different values for 1 and 2 Ecoflo biofilters
(or a dose of approximately 50 L and 100 L for other treatment systems).

*The length of the cable is pre-set to that length at the plant.
**The alarm float has to be moved 50 mm higher than its initial position on the float tree. The length of the cable must remain at 3" (75 mm).
Finally, adjust the valve so that water flows into the Ecoflo
biofilter at an acceptable rate and the dosage time for each hydraulic event
(40 L, 8.8 imp. gallons, 10 US gallons) is at least 30 seconds. To check if the dosage is appropriate, the tipping bucket should fill-up a
maximum of 12 times per hydraulic event.

7. Maintenance
The pumping station has mechanical components, therefore, it is preferable to conduct an annual preventive inspection. Furthermore,
it is important to comply with the regulations regarding the septic tank emptying in order to prevent large particles from escaping the
septic tank and blocking the pump. We strongly recommend you empty your pumping station at the same time as your septic tank.
