ABS lifting station Nirolift & Sanisett
1.3
Commentary on the legal regulations covering the use of lifting stations for the
pumping of faecal free effluent.
Automatically operated lifting stations are prescribed if:
the water level in the odour lock of the effluent source lies below the sewer backwash level.
rainwater gullies are present where the upper edge of the inlet grid lies below the sewer backwash level.
The sewer backwash level is the maximum possible water level in the public sewer network. Information on this
can be obtained from your local authority. If the backwash level has not been fixed by the local authority, then
the surface level of the roadway at the connection point is taken to be the level.
The regulations also require that all waste-water which can cause offensive odours must be collected in closed,
odour-tight, and free-standing collection tanks.
The collection tanks must be vented by vent pipes which are brought above roof level.
ATTENTION
The regulations of DIN 1986/100 EN 12050 and 12056 should be observed!

Description
The waste-water lifting stations of the Nirolift/Sanisett consist of a synthetic collection tank which is waterproof
in according with DIN/EN 12050-2, together with a cover plate with odour preventing filter and lockable floor
inlet.
The Sanisett is also supplied with a junction piece for the discharge line and a bracket for the level control.
The collection tank is supplied as standard with a number of closed off inlet ports. The inlet ports DN 100
Nirolift and DN 100/150 Sanisett can be opened as required (See Figure 3).
The waste water entering via the inlet ports is collected in the collection tank. When a preset liquid level is
reached then the Nirolift/Sanisett with one submersible pump is started up either by means of the float switch
fitted to the pump itself, or connected into the control panel, and is switched off again when the tank is emptied.
NOTE
In the case of twin units installed in accordance with DIN/EN 12056, one submersible
pump must be capable of pumping all the effluent. The second pump is only a stand-
by unit.
Safety
The general and specific health and safety hints are described in detail in the separate booklet Safety Hints. If
anything is not clear or you have any questions as to safety make certain to contact the manufacturer ABS.
