1.9 Installation of wastewater lifting plants, where and why 

General aspects 

Building regulations | According to state building regulations, buildings 

and other structures may only be erected if the elimination of wastewater is 

properly and permanently ensured. Property grounds on which wastewater 

arises must be connected to the public sewer system, if they are ready 

for operation. It is this requirement, i.e., the direct connection of a 

property's drainage system to the public sewer system, that gives rise 

to the problem of backflow in this area. The frequency of such backflows 

depends on the type of sewer system used, i.e. whether it is a separate or 

combined system. In separate sewer systems, dirty water and rainwater 

are transported in separate pipe systems. This makes it less common for 

backflows to occur in dirty water sewers due to factors such as illegal 

introduction of waste, pipeline blockages and operationally necessary 

sewer measures; however, such backflows can never be entirely prevented. 

For economic reasons and to ensure the self-cleaning capability of the 

system, the current practice is to dimension drainage systems for a 

moderate level of rainfall. However, it must be expected that heavy rainfalls 

exceeding the amount used as the basis for calculation will occur. This 

means that a drainage system overload could occur at any time. 

Sewer backup | The physical effects of a sewer backup are based on 

the law of communicating tubes. If a backup occurs, the wastewater finds 

its way through these pipes into the property drainage system because the 

pipe systems of the property drainage system are directly connected to 

the public sewer system. The water rises to the same level as the water in 

the public sewer. This means that wastewater will continue to escape from 

all unprotected openings, such as floor drains, toilets, etc., until the water 

levels have reached equilibrium (Fig. 1-1). 

Backflow level | This results in a specific elevation or level below which 

special measures must be implemented as part of the property drainage 

system to protect against the risk of backflows on the property. This level 

is referred to as the backflow level. The pertinent backflow level is defined 

by the local authorities in the town by-laws. If no such definition exists, DIN 

EN 12056-4 and DIN 1986-100 defines the backflow level as the level of 

the top edge of the street above the location where the property drainage 

line connects to the public sewer system. 

Nevertheless, the backing up of water even above this level cannot be 

completely ruled out, for instance due to pipe blockages. If backed-up 

water penetrates within buildings into unprotected rooms, masonry walls 

and foundations can become saturated. This backed-up water can also 

cause water damage to furnishings. There may also be health risks due to 

infections. For these reasons, the risk and potential damage of backflowing 

wastewater must be kept as low as possible using preventive measures. 

According to town wastewater by-laws, the responsibility for these 

measures generally lies with the property owner. Property owners can hire 

suitable experts, such as qualified planners and fitters, to properly plan and 

execute such measures.

Sewer backflow 

0150.16.70


Protection against backflow | The greatest possible protection against 

backflow can be achieved with a wastewater lifting plant with a pressurised 

line that runs to above the backflow level (Fig. 1-2, 1-3). 

Backflow level 

Figure 1-2: 

Protection against backflow with an incline to the 

sewer using a wastewater lifting plant 

Regulations | DIN1986-100, “Drainage systems on private ground” and 

EN 12056 “Gravity drainage systems inside buildings” require that dirty 

water arising below the backflow level and precipitation water from surfaces 

below the backflow level be brought into the public sewer system in a 

manner than protects against backflows through the use of an automatic 

lifting plant. 

Drainage systems are planned according to the principle that “arising 

surface water must be diverted away from the building and not brought into 

the building.” Accordingly, surfaces exposed to rain must be drained by 

separate pump stations outside of the building. 

All drainage features situated above the backflow area must be drained 

with natural inclines (gravity principle); the wastewater from these drainage 

features may not be diverted through anti-flooding valves and may only be 

diverted through wastewater lifting plants in exceptional cases in which this 

is absolutely necessary (e.g. old building renovation).

1.10 Description: design / type 

Design ... 

-PE | Polyethylene (PE-HD), rotated, collecting container. 

-VA | Stainless steel (1.4571), welded, collecting container. 

Type ... 

-K | Pump design, hydraulic component with ducted wheel (particle size 

70 mm or 100 mm with type K-75). 

The ducted wheel is suitable for pumping dirty water containing faecal 

matter as well as for pumping wastewater with firm, short, fibrous solids 

and thick matter, sludge and organic materials. 

Figure 1-4: 

3D ducted wheel 

-V | Pump design, hydraulic component with free-flow impeller (particle 

size 80 mm). 

A large open space in the pump housing (a sphere passage) allows the 

liquid to easily flow through the suction opening into the pump chamber 

and allows solid and long-fibred thick matter, such as long sanitary towels, 

textiles, etc. to pass through the pump housing without difficulty. 

Another advantage: Since free-flow pumps do not have a choke gap 

between the impeller and the pump housing, this design offers great 

operational reliability for applications with very long periods of inactivity. 

This prevents the impeller from rusting into place, which would result in 

blocking of the pump.

Backflow 

level 

- Plants consisting of drainage fixtures, pipes and other components 

that collect wastewater and drain it via gravity. A wastewater lifting 

plant can be part of a gravity drainage system. 

- All drainage objects above the backflow level are to be drained by 

means of natural incline and may therefore not be connected to the 

wastewater lifting plant. 

- Drainage points beneath the backflow level must be secured 

against backflow. The protection against backflow is provided by 

wastewater lifting plants with backflow loop. Only designs with a 

backflow loop offer a high level of protection against backflow. 

- If the backflow level has not been determined by the responsible 

authority, the height of the road at the point of connection shall 

apply. 

Selection - The planning and selection of wastewater lifting plants must take 

place according to DIN EN 12056-4 and DIN 1986-100.

- Before installation of the lifting plant or anti-flood valve, it is 

necessary to evaluate whether the plant being installed conforms to 

the approved planning documents and applicable standards. 

- Accessibility to installation, maintenance, inspection and disposal 

must be ensured including during operation. 

- The installation site must have sufficient load-bearing capacity and 

satisfy the regulations for noise prevention in structures. 

- The existing drainage pipes have to be checked for suitable 

connection height. 

- Surface water arising outside of the building and below the 

backflow level must be transported separately from the building 

wastewater and outside of the building via a wastewater lifting 

plant. 

- The useful volume of the lifting plant must be greater than the 

pressure line volume extending through the check valve up to the 

backflow loop, but no less than 20 l. This ensures that the volume 

in the pressure line will be exchanged during pump operation.

shutoff valve 14 (accessory) is installed between the check valve and Y-pipe. Dummy connection flanges 4 for 

inlet DN 100 or 150 (3x above/on type 1.1-1.4, plus additional 2x on side/on type 2.1-2.4) are provided on the 

container. The corresponding connection parts are available as accessories. A pipe connection 6 DN 100 serves 

for connection of the ventilation pipe. The drain screw 2 (base drain) is located at a low point on the side of the 

container, where a hand diaphragm pump can also be connected. 

The lifting plant is connected to the switch box 17 and the compact compressor 18 via sufficiently long pump 

cables and the pneumatic control lines.

0150.16.70 

Description | The wastewater flows through the inlet into the collecting container. If the wastewater reaches 

"level 1", pump 1 is switched on and the wastewater is pumped through the pressure line (rising pipe, check valve, 

Y-pipe, special fastening element) through the backflow loop and into the sewer system. If the water level falls 

back to the "follow-up time level", the follow-up time of the pump is started and the pump is switched off when 

"level 0" is reached. The switchover protection automatically swaps the activation order after each time the pumps 

are started up. This prevents the suction opening of a pump from accumulating thick matter deposits as a result 

of being inactive for too long. In addition, if there are large volumes of wastewater and "level 2" is reached, the 

second pump will start up. The automatic pump control is handled by a pneumatic switch based on the level of 

liquid (membrane switch). A compact compressor generates continuous compressed air and feeds this into the long 

pitot tube of the collecting container via a corresponding control line. At the end of the pitot tube, the compressed 

air bubbles freely into the wastewater. An opposing pressure proportional to the liquid level arises in the pitot tube 

(measurement tube, short and long). This pressure trips the pressure sensor (in the switch box), activating contacts 

that switch on the pumps and trigger the high alarm. The volume between the two switch points "level 0+1" 

corresponds to the useful volume of the collecting container. If the pumps are not switched on due to an existing 

fault / defect (see fault causes), an alarm is triggered in the switch box upon reaching of "level 3," and the situation 

must be evaluated. If no inspection takes place and wastewater continues to enter, forced activation of both pumps 

takes place upon reaching level 5 (with simultaneous triggering of the alarm), and the pumps are switched off again 

at level 4. This automatic level switch is set to the corresponding switch points by the manufacturer (for use of the 

inlet from above). Ventilation of the container and the constant rising of the control lines are of critical importance 

for proper functioning of the automatic level switching. 

Before commissioning, the lifting plant must be filled with water and the switching operations tested.

4.8 Information on potential-free contact – collective fault signal / operating signal 

The switch boxes all have a potential-free contact for transmitting a 

collective fault signal and an operating signal. The contact is realised with 

a changeover contact. This electrically isolates the electrical power circuits 

of the devices being connected. 

The pin assignment information can be found in the corresponding circuit 

diagram (see appendix or enclosure with switch box). 

4.9 Environmental conditions 

The installation site of the lifting plant must be easily accessible; in other 

words, parts of the wastewater lifting plant that must be operated and 

maintained must have a clearance on all sides from the wall or other 

equipment of at least 0.6 m. 

It must be possible to run the inlet line DN 100 or DN 150, the pressure line 

DN 80 or DN 100, the ventilation line DN 100 and the electrical connection 

cable into or out of the installation area. 

A position safe from flooding must be selected for the switch box and a wall 

area of approx. W x H = 300 x 300 mm or 450 x 650 mm must be kept 

free. 

For installation of a hand diaphragm pump, a wall surface of W x H = 300 x 

800 mm and a pump sump of at least L x W x H = 400 x 400 x 450 must 

be provided.

waste water. 

Connect the inlet pipe 

PE collecting container | Four horizontal pipe connections DN 150 (2 

on front arranged vertically, 2 on side arranged opposite) and 1 vertical 

pipe connection DN 150 (from above) are available for connection of 

the inlet line(s). The connections are all sealed. After determining which 

connections will be used, the respective connection caps must be sawn 

off at the corresponding notch. The inlet line provided by the installer with 

shutoff valve is then connected appropriately to the spigot end. 

The connection dimensions of the connections 

correspond to DIN EN 877. 

The inlet line must be dimensioned and 

installed according to DIN 1986 Part 2.

be run to the main or secondary 

exhaust ventilation line. 

The ventilation of the plant may 

not be connected to the intake 

ventilation line of a grease 

separator. 

The pressure line of the 

wastewater lifting plant must be 

run such that the base of the 

backflow loop will be above the 

backflow level. 

The pressure line must be 

appropriately relieved of its own 

weight. 

A check valve must be installed 

in the pressure line. If no shutoff 

mechanism is situated after this 

point in the plant, the check 

valve must have an air intake 

mechanism or some other option 

must exist for draining. 

(Included as standard with these 

lifting plants). 

6 

The line must be secured against 

coming unattached at connections 

that are not designed to elastically 

accept longitudinal forces. 

The minimum nominal width of the 

pressure line must comply with 

Table 5 of DIN EN 12056-4. 

Pressure lines must always be 

connected to ventilated ground 

lines or mains. The connections 

must be designed as connections 

for pressure-free lines. 

The pressure line must accept 

at least 1.5 times the maximum 

pump pressure of the plant. 

Appropriate pressure pipes must 

be used.

Notes on pump capacity, pump height and total pump height 

Pump rate in l/s | Rate of flow at which the pumping media is pumped 

up to the total pump height by the wastewater lifting pump at its operating 

point. 

Pump height in m | Pressure head applied by the wastewater lifting 

pump at its operating point for overcoming the static height difference as 

well as the total loss height in the pressure line. 

Total pump height in m | The total pump height is the sum of the static 

pump height and the pump head losses in valves and fittings plus pipe 

friction losses (all in m). 

Installation of a shutoff valve (accessory) 

Standards require that a shutoff element be installed for pressure lines of 

DN 80 or larger. 

ACO Haustechnik offers a matching shutoff valve DN 80 or DN 100 as an 

accessory for these lifting plants, specifically:

between the wastewater lifting plant and 

the pipe base of the backflow loop: 

The pump capacity and pump height of 

the wastewater lifting plant pump must 

be greater than or equal to the total 

pump height.

The switch box must be installed at an easily accessible location that is safe from flooding (consideration should 

also be given to ensuring that the audio alarm signal can be heard easily). A free wall surface of approx. W x H 

= 300 x 300 mm (plug-ready switch boxes) or 450 x 650 mm (connection-ready switch boxes) is required. The 

distance from the switch box installation site to the wastewater lifting plant also depends on the length of the pump 

connection cable (factory-connected cable 5 m long, 7 m on K-55 and K-75), which is already connected to the 

connection box of the pump motor. 

Plug-ready switch box | A 16-A CEE socket must be installed in the 

vicinity of the switch box for all plug-ready switch boxes with 1.5 m power 

cable and CEE plug. 

An operating voltage of 400 V / 50 Hz is required. Use circuit breakers on 

all poles, max. 16 A, for protection. 

Connection-ready switch box | An operating voltage of 400 V / 50 Hz 

is required for all connection-ready switch boxes. Use circuit breakers on all 

poles, max. 32 A, for protection. The customer must run a corresponding 

cable and connect it according to the circuit diagram. 

CAUTION 

The electric connection of the control 

has to be carried out by an expert in 

keeping with the applicable regulations 

of the German Association of 

Electricians.
