Ecolift functional principle

How does a hybrid

lifting station work?

A hybrid lifting station combines the safety of a lifting station with the efficiency of drainage via a natural slope.

During normal operation, wastewater flows with gravity through the Ecolift XL into the public sewer. When flooding

occurs backwater flap(s) automatically shut to protect the building. Pump(s) then activate to discharge the

building’s wastewater into the public sewer when backwater flap(s) are closed.

Hybrid lifting stations make use of

the natural slope to the sewer.

Direct drainage

is economical.

A lifting station always pumps wastewater.

This is why it constantly consumes energy.

A hybrid lifting station is different: It only

starts pumping when it is really needed. In

addition to the improved eco-balance due

to lower power consumption, there is a

second major economic advantage: cost

reduction due to less required maintenance.

Motorised flap(s) close to prevent

backwater from entering from the

surcharged sewer.

Direct drainage

is quiet.

Despite cutting-edge mechanical designs

and the latest noise reduction measures –

pumps make noise. This can be a nuisance,

particularly when the pumps are in con-

tinuous operation. A hybrid lifting station

reduces this to an absolute minimum as

the pumps only run during backwater AND

when the building is producing wastewater.

The building’s wastewater is pumped

into the surchaged sewer during times

of backwater.

Direct drainage

is safe.

Absolute operational safety – even in the

event of a power failure . A hybrid lifting

station provides this safety, since the

gravity drainage functions even without.

It simply uses the natural slope to dispose

of the wastewater even if there is a power

outage.

Function backwater pumping station

Protects in the event of backwater

The backwater flap prevents wastewater from the public

sewer from backing up through the drainage pipe and

flooding the building.

Disposes in the event of backwater

Despite backwater from the public sewer and closed

backwater flap(s), domestic wastewater can be disposed

of via a pump. This ensures that the building’s drainage

system functions even in the event of backwater.
