3 Background What causes backflow? Wastewater can backflow into buildings whenever wastewater can no longer drain off optimally into the public sewers. The dimensioning of drainage installations today takes into consideration economic aspects and selfcleaning effects based on average rainfall events. However, heavy rainfall which exceeds the reference rainfall level can also occur. This means that the drainage installations can be overloaded at any time. In addition to periods of heavy rainfall, wastewater can also be prevented from draining off as quickly as required by unwanted reductions in pipe cross sections caused by deposits or blockages in sewer pipes, not to mention cracked pipes, pump failures in public sewers, and floods all can lead to sewage backflowing into a building. Levels are rising The flood on the River Oder in 1997, the Whitsun flood, the Flood of the millennium in 2002 on the Elbe and its tributaries, the major flooding in the Alps in 2005, and the extraordinary amount of snow in East Bavaria in February 2006 all point in one direction: extreme floods and heavy rain and snow falls are increasing across the whole of Europe. And they will become even more frequent in future. Flooding is basically a combination of two factors: water input and surface area. The first has increased: more heavy rainfall. The second has decreased: less unpaved and unbuilt-up areas. Paradoxically, the construction of flood prevention dikes on rivers has already increased the frequency of flooding. Scientists at the Max Planck Institute for Meteorology have observed a long term trend since the middle of the 70s of an increase in flood events affecting numerous rivers in west and south Germany and neighbouring countries. Even if these rivers do no break their banks, there is always a risk that sudden heavy rainfall can affect already overloaded sewers which are often only designed to handle average rainfall events. If the capacity of the sewer shafts is exceeded, wastewater follows the natural law of communicating pipes: it flows back into buildings. To prevent backflow, drainage installations below the backflow level have to be properly protected. 3 Local authorities are not liable for extraordinary floods or rainfall Home owners can no longer rely on the public sewers during extreme rainfall events. If water flows out of sewers during floods of the century, and causes damage to private homes, local authorities cannot be held liable according to the decision handed down by the German Federal Court of Justice (BGH) in Karlsruhe. Local authorities can claim force majeure under such circumstances. Although local authorities are responsible for the safe operation of the sewer system and are responsible for any damage caused during normal conditions, this no longer applies to completely unusual and rare disastrous rainfall, according to the BGH. Their justification is that liability for risks associated with pipe networks are limited by the economic strength of the local authorities. Extra costs for wider pipes have to stay within reasonable proportion to the additional protection provided by such measures. No fixed limit has been defined. It is clear however that local authorities no longer have to dimension their systems to cope with rain which occurs more rarely than every 100 years. This decision handed down in May 2004 strengthens the hand of local authorities who stipulate that landowners bear sole responsibility for protecting their property against backflow.

4 Background Backflow level Backflow level 4 The backflow level is the highest level (water level) to which wastewater can rise in a drainage installation. The backflow level is defined by the local authority (local bylaws). In the absence of any specific definition, the backflow level is usually taken as the level of the road above the sewer connections. All drainage installations below this level are at risk of backflow and should therefore be protected by implementing the appropriate measures.

5 Background Installation principles for backflow safety valves Incorrect Correct Drainage installations which lie above the backflow level (figure left) must not be connected to a backflow safety valve (lifting plant or backflow stop). This is because it would prevent wastewater draining off properly from installations above the backflow level during a backflow situation. According to the principle of communicating pipes, the wastewater would first flow up out of the deepest lying drains below the backflow level and flood the cellar. This is why all drainage installations installed above the backflow level must be connected to the sewer downstream of the backflow stops (figure right). During a backflow event, the down pipe will not fill higher than the level of the street, and the backflow stop prevents the wastewater backing up into deeper lying drainage installations instead it forces it to rise up through the manhole cover of the sewers. Type classification of backflow stops pursuant to EN Type Installation Automatic seal Emergency seal Area of application 0 Horizontal pipe 1 0 rain water installations 1 Horizontal pipe 1 1* rain water installations 2 Horizontal pipe 2 1* rain water installations/ wastewater free of faeces 3 Horizontal pipe 1 (pneumatic 1 wastewater free faeces, wasteor electric) water containing faeces (designated "F") 4 Fitted in floor drains 1 1* wastewater free of faeces 5 Fitted in floor drains 2 1* wastewater free of faeces 5 * Emergency seal can be combined with an automatic seal. The use of different types is regulated by national law. The following table defines the specific authorisations applying to Germany, Austria and Switzerland. Country Differences Germany Austria Switzerland Types 2, 3 and 5 are authorised for wastewater free of faeces. Only Type 3 with designation F can be used for wastewater containing faeces. Types 0 to 5 are authorised for use with wastewater free of faeces. Only Type 3 can be used for wastewater con taining faeces. Backflow stops can only be used subject to prior case-by-case authorisation.

6 Which backflow safety valve is best for which application? Wastewater type Wastewater outflow Down gradient into the sewers No gradient to the sewers backflow level backflow level Wastewater free of faeces ACO Junior Cellar drain with Type 5 backflow stop ACO Sinkamat-K Underground (top) or above ground (below) lifting plant for wastewater free of faeces 6 ACO Triplex-K Backflow stop for continuous pipe Type 2 Wastewater containing faeces ACO Quatrix-K Backflow stop for continuous pipes Type 3F ACO Muli-Star MDS1/MWS1 Lifting plant for wastewater containing faeces

7 The benefits of ACO Triplex-K backflow safety valves and Quatrix-K using the shaft system Extensions for deeper installation If a backflow stop has to be installed at a much deeper level for structural reasons, it is easy to convert the ACO backflow safety valve shaft systems with the optional extensions. It is also easy to manually put together several extensions if required. Sealing flange for pressurised water If the floor plate needs to be protected against pressurised water, it is possible to equip the shaft system with an optional sealing flange. This flange provides reliable protection to keep the soil moisture out of the cellar. The height of the flange is infinitely adjustable for easy adaptation to the level of the floor plate. Adjustment to the tile pattern and floor level The top section for load class K3 is infinitely height adjustable and tiltable. This allows the cover to be perfectly adjusted to the floor height and the tile pattern. A specially adapted locking system also prevents small children from removing the cover. 7 Multi-option cover to suit customer s requirements Use either side of the cover as required. The uniform side is a plastic cover. If tiles are laid in the installation room, turn the cover round and use the side which is recessed to accommodate the matching tiles.

8 The ACO Junior cellar drain with backflow stop The ACO Junior cellar drain with backflow stop is a Type 5 backflow stop in accordance with EN Because of its compact dimensions, this cellar drain is ideal for refurbishing cellars where the drainage systems are being upgraded by installing a backflow stop in one of the old drains. The ACO Junior cellar drain with backflow stop has two flaps including an emergency seal. It is installed in the floor plate. Wastewater enters the drain via the grating. It is also possible to connect drainage installations to the drain, such as showers, washing machines or sinks lying beneath the backflow level, by adding a DN 50 inlet to the drain on site. During normal operating conditions, the flaps hang loose. The force of flowing wastewater pushes open the flap in the flow direction to drain the wastewater in the direction of the sewer. If there is backflow, the wastewater backing up from the sewer flows against the normal flow direction and comes into contact with the outer backflow flap. This prevents wastewater from the sewers from flowing back into the building. The second flap is an extra safety feature to ensure that the backflow stop functions even when the first flap fails to close properly because of the presence of dirt, etc. The emergency seal integrated into the second flap provides additional security and can be operated manually. Note that when the emergency seal is locked in position, it also prevents wastewater generated in the building from flowing into the sewer. It is therefore very important that this emergency seal is reopened again immediately after returning to the building, e.g. after a holiday. 8 Product benefits Compact dimensions ideal for refurbishment No tools required to assemble and dismantle the sludge bucket and backflow device Rotatable top section for optimal adjustment to the tile pattern Extensions available for flexible adjustment to deeper installation positions Installation example ACO Junior cellar drain with backflow stop DN 100 Type 5 pursuant to EN

10 ACO Triplex-K-2 double backflow stop with shaft system The ACO Triplex-K-2 backflow stop is a Type 2 backflow safety valve pursuant to EN This product has been specially designed for installation in floor plates. The backflow stop can be equipped with a sealing flange against pressurised water. The ACO Triplex-K-2 is specified for use with wastewater free of faeces. It must only be connected to drainage installations generating wastewater free of faeces, e.g. floor drains, showers or washing machines located below the backflow level. During normal operating conditions, the flaps hang loose. The force of flowing wastewater pushes open the flap in the flow direction to drain the wastewater in the direction of the sewer. If there is backflow, the wastewater backing up from the sewer flows against the normal flow direction and comes into contact with the outer backflow flap. This prevents wastewater from the sewers from flowing back into the building. The second flap is an extra safety feature to ensure that the backflow stop functions even when the first flap fails to close properly because of the presence of dirt, etc. The ACO Triplex-K-2 also has an emergency seal. This is integrated within the rear flap. This is an additional safety feature and is actuated manually. The emergency seal can be easily actuated without a great deal of force and is safely in position when a loud click is heard. Note that when the emergency seal is locked in position, it also prevents wastewater generated in the building from flowing into the sewer. It is therefore very important that this emergency seal is reopened again immediately after returning to the building, e.g. after a holiday. 10 Product benefits Minimal intrinsic gradient 12 mm, and so optimal for refurbishment Height adjustable top section for perfect adaptation to floor level Optional step-wise height adjustable sealing flange for flexible adaptation to the sealing level Easily convertible to an automatic backflow stop for wastewater containing faeces Installation example ACO Triplex-K-2 double backflow stop, DN 100 Type 2 pursuant to EN for installation within floor plates.

14 ACO Quatrix-K black water automatic backflow stop with shaft 14 The ACO Quatrix-K black water automatic backflow stop corresponds to Type 3F pursuant to EN This product is specially designed for installation in floor plates. The backflow stop can be retrofitted with a sealing flange to protect the device from pressurised water. The ACO black water automatic backflow stop is designed for use with wastewater containing faeces. Type 3F backflow stops must be used whenever toilets are installed below the backflow level. Two flaps are open during normal operations. When water from the sewers backflows into the pipes, the operating stop is automatically closed by a pneumatic/electric control device. As soon as the wastewater rises up above the permissible height in the pipe, an under pressure sensor sends a signal back to the control unit. The control unit automatically operates the electric motor to close the operating stop. When water no longer backflows into the system, a sensor informs the control unit and the flap is automatically reopened. The drainage installations connected to the backflow stop must not be used during a backflow situation! The presence of backflow is signalled by an optical and acoustic alarm. An integrated battery maintains continuous operations for up to 24 hours during a power cut. The ACO Quatrix-K also contains a manually operated emergency seal. The seal can be used manually.

26 ACO Muli-Star MDS1/MWS1 wastewater lifting plant Cellar rooms lying below the backflow level, and with no slope towards the sewers, must be drained in all cases with the help of a lifting plant. ACO has specially developed the ACO Muli-Star MDS1/MWS1 wastewater lifting plant for applications in detached houses and basement apartments: compact dimensions and five possible connections at different points make it ideal for all applications, especially when the installation situation is otherwise problematic. On the pressure-side, the compact lifting plant has a 57 mm impeller passage to ensure blockage-free operation of the system. The extra integrated ball backflow preventer ensures that backflowing sewage never flows back into the lifting plant. The low weight of 31 kg, and the readyto-install condition on delivery, guarantees rapid installation of the lifting plant. Installation example 26 ACO Muli-Star lifting plant for black water as a free standing installation in a frost free room.

28 ACO Muli-Max-F mono / duo pump shaft The ACO Muli-Max-F pump shaft made of PE-HD has particularly compact dimensions. The telescopic height-adjustable top section enables installation to a total depth of 3 metres. The pump shaft is available in three load classes: With cover Class A 15 supports weight of pedestrians With cover Class B 125 supports weight of cars With cover Class D 400 supports weight of trucks Thanks to its innovative design, the new ACO pump shaft cannot be pushed upwards by groundwater even if the water table rises to the top of the manhole cover. The collection tank is shaped to prevent the collection of sediment. The inside is designed to accommodate a whole range of different pump types depending on the specifications and applications. The pressure pipe and the tension chain are made of high quality stainless steel. The pneumatic water level switch guarantees high levels of operational safety. Two types of control box are available (with and without display), which guarantee optimal function and monitoring. The ACO Muli-Max-F multipurpose pump shaft is suitable for single and multifamily homes, for commercial properties, in industry, and for pressure drainage. Mono or Duo ideal pump stations for every application 28
