- the system 400 can comprise a filter 430, which is meant for purifying drain water going to the device 410.
- the filter 430 can be a filtering unit presented in patent application FI 20165355 .
- the system 400 can comprise a faucet 480, where water coming from the cold-water pipe 482, 484 and hot water pipe 481 are mixed, so that a user gets mixed water of a desired temperature from the upper shower, hand shower or faucet tap 486.
- the tap water coming from the faucet 480 through the shower or tap 486 goes into the outlet 140, where exceedingly cold or dirty drain water is guided to the sewer 429, and sufficiently warm and clean drain water is guided by means of the guiding unit 256 along the pipe 422 to the filter 430, where the water is further purified for the device 410.

- Drain water that has relinquished its thermal energy is transported along the drain pipe 424 to the sewer 429.
- water removed from the outlet 140 can be transported directly for example as flushing water to a toilet bowl or into a water tank, from where it is available for example for a toilet bowl or device 410.
- the drain water which has relinquished its thermal energy in the device 410 can be transported to a toilet bowl as flushing water or to a tank, from where it is available for a toilet bowl or some other device, which can use purified water.
- Preheated water in turn continues from the device 410 along the pipe 484 to the faucet 480, from where a user can use it as such or as mixed with hot water that has come to the faucet 480 along the pipe 481.

- the outlet 140 is meant to operate independently without outside control when it receives water to be removed.
- the pump starts when its control 257 receives measurement data from a sensor of the sensor part 25, which fulfils a predetermined condition for starting the pump.
- the pump is in turn turned off, when the condition is no longer fulfilled based on the measurement data.
- the condition can be a certain water surface height, whereby when the water surface rises in the seal 250, the pump is turned on and water starts to flow through the pump instead of through the connection 143 onwards to the connection 352 and the device 410.
- the pump shuts off when the water surface has sunk below the level of the surface height sensor functioning as an ON/OFF switch. If the power of the pump is not sufficient for pumping water, the surplus water normally goes into the connection 143.
- the condition can be the measured surface height, whereby when the water surface rises in the seal 250, the pump is turned on and water starts to flow through the pump and connection 354 instead of through the connection 143 to the device 410.
- the capacitive sensor measures the water surface height and adjusts the pump power to be suitable based thereon. When the water flow has stopped, or the water flow is very low, the pump shuts off, because the water level has sunk in the seal 250 below the level predetermined as the condition for running the pump. The pump restarts when the sensor observes more water in the seal
- the condition can be the water temperature and/or purity, whereby the pump can be used for guiding water of different temperatures for example to a centralized heat recovery tank, which is situated for example in an apartment house's basement. If the temperature sensor observes that the water to be removed is too cold, and/or the optic sensor observes that it is too dirty, the pump is not turned on. Thus, the water is guided directly to the connection 143. When the sensor(s) observe that the water temperature has risen, and/or the water has become cleaner, the pump is turned on and the water is guided by means of the pump to the connection 352.
- the system 400 can comprise flow sensors in the pipes 481, 484 going to the faucet 480 and a magnetic, motor or corresponding valve, with which it is possible to shut off the water flow.
- the flow sensors comprise data transfer means, by means of which it is possible to send data to the control 257
- the valve comprises data transfer means, by means of which it is possible to receive data from the control 257.
- the flow sensors are meant to observe a flow in the pipes 481, 484 when the shower or tap 486 is open and to inform the control 257 that it has observed the flow. If the sensor of the sensor part 255 which observes presence of water observes that no water is entering the outlet 140 during a predetermined time, the control 257 can deduce that the outlet 140 grate is clogged and send a command to the valve to shut.
- system 400 can have a water tank in the pipe 491 for washing machine water.
- a valve has been connected to the tank in the pipe 491, which valve is equipped with data transfer means, by means of which it is possible to communicate with the flow sensors of the pipes 481, 484 and/or control 257.
- the valve control or control 257 commands the valve to open, so that the tank is emptied into the outlet 140.
- the control 257 commands the pump to pump water from the tank to the device 410.
- the system 400 can be integrated into different stages of process industry, for example cleaners, whereby water passing into the sewers 429 can first be treated in the outlet 140 and thereafter be transferred into the sewer system of the cleaners to be utilized.

control 257 can receive measurement data, determine control commands based on the measurement data and send control commands to thepump 256 and/or valve in order to control their operation. - Additionally, the
outlet 140 can comprise a post-filter, which can be detachably installed between the pump andconnection 354 in the structures of thepart 142, so that it is protected by the structures. - The surface area of the openings in the post-filter are smaller than in the
filter 146, i.e. it is denser than thefilter 146. - The post-filter can be plate-like, round, oval or star-shaped.
- The post-filter is meant to filter the drain water exiting from the
outlet 140 so that with its aid, finer solid material is further separated from the drain water, which material has passed through the grate andfilter 146. - The
center hole 158 of thefilter 146 can be meant to guide exiting water to theseal 250, so that it does not go to thepump 256 and cause clogging of the pump. - Additionally, the
outlet 140 can comprise asurface height sensor 260 for observing the surface height of the water on thefilter 146. - The
sensor 260 can be installed in the upper edge of theupper part 145 of thepart 142, so that it is at the height of thefilter 146, which is lower than the upper edge of theedge 159. - The
sensor 260 can comprise data transfer means, by means of which it can send data to thecontrol 257. - If the
filter 146 is clogged, then thesensor 260, when it observes the water surface rising on thefilter 146, sends information to thecontrol 257, which based on the information keeps the pump turned off or turns it off, so that dirty unfiltered water can not get from theoutlet 140 via the pump to thefiltering unit 430 and thedevice 410. - The
filter 146 and the post-filter are replaceable or self-cleaning. - Due to the
outlet 140 the carbon footprint caused by purification of the sewer water is reduced, when due to thefilter 146 and the post-filter the amount of impurities ending up in the sewers is reduced and less energy is used in water treatment plants for purifying cleaner sewer water. -
Fig. 4 shows aheat recovery system 400, by means of which it is possible to recover thermal energy from used water. - The
system 400 comprises anoutlet 140 as shown in connection with the preceding figures. - Additionally, the
system 400 comprises adevice 410, which is meant to utilize drain water coming from theoutlet 140 for preheating cold tap water. - The
system 400 can comprise afilter 430, which is meant for purifying drain water going to thedevice 410. - The
filter 430 can be a filtering unit presented in patent applicationFI 20165355 - Additionally, the
system 400 can comprise afaucet 480, where water coming from the cold-water pipe hot water pipe 481 are mixed, so that a user gets mixed water of a desired temperature from the upper shower, hand shower orfaucet tap 486. - In the
system 400 the tap water coming from thefaucet 480 through the shower or tap 486 goes into theoutlet 140, where exceedingly cold or dirty drain water is guided to thesewer 429, and sufficiently warm and clean drain water is guided by means of the guidingunit 256 along thepipe 422 to thefilter 430, where the water is further purified for thedevice 410. - Purified water which has passed through the
filter 430 runs along thepipe 423 to thedevice 410, where cold water coming from thepipe 482 is preheated with its thermal energy. - Drain water that has relinquished its thermal energy is transported along the
drain pipe 424 to thesewer 429. - Alternatively, water removed from the
outlet 140 can be transported directly for example as flushing water to a toilet bowl or into a water tank, from where it is available for example for a toilet bowl ordevice 410. - Alternatively, the drain water which has relinquished its thermal energy in the
device 410 can be transported to a toilet bowl as flushing water or to a tank, from where it is available for a toilet bowl or some other device, which can use purified water. - Preheated water in turn continues from the
device 410 along thepipe 484 to thefaucet 480, from where a user can use it as such or as mixed with hot water that has come to thefaucet 480 along thepipe 481. - Drain water coming from a
washing machine 490 alongpipe 491 and/or from asink 492 alongpipe 493 can be used in a corresponding way as water coming from thefaucet 480 for preheating cold water in thedevice 410. - The
outlet 140 is meant to operate independently without outside control when it receives water to be removed. The pump starts when itscontrol 257 receives measurement data from a sensor of the sensor part 25, which fulfils a predetermined condition for starting the pump. The pump is in turn turned off, when the condition is no longer fulfilled based on the measurement data. - The condition can be a certain water surface height, whereby when the water surface rises in the
seal 250, the pump is turned on and water starts to flow through the pump instead of through theconnection 143 onwards to theconnection 352 and thedevice 410. The pump shuts off when the water surface has sunk below the level of the surface height sensor functioning as an ON/OFF switch. If the power of the pump is not sufficient for pumping water, the surplus water normally goes into theconnection 143. Alternatively, the condition can be the measured surface height, whereby when the water surface rises in theseal 250, the pump is turned on and water starts to flow through the pump andconnection 354 instead of through theconnection 143 to thedevice 410. The capacitive sensor measures the water surface height and adjusts the pump power to be suitable based thereon. When the water flow has stopped, or the water flow is very low, the pump shuts off, because the water level has sunk in theseal 250 below the level predetermined as the condition for running the pump. The pump restarts when the sensor observes more water in theseal 250. - Alternatively, the condition can be the water temperature and/or purity, whereby the pump can be used for guiding water of different temperatures for example to a centralized heat recovery tank, which is situated for example in an apartment house's basement. If the temperature sensor observes that the water to be removed is too cold, and/or the optic sensor observes that it is too dirty, the pump is not turned on. Thus, the water is guided directly to the
connection 143. When the sensor(s) observe that the water temperature has risen, and/or the water has become cleaner, the pump is turned on and the water is guided by means of the pump to theconnection 352. Additionally, thesystem 400 can comprise flow sensors in thepipes faucet 480 and a magnetic, motor or corresponding valve, with which it is possible to shut off the water flow. - The flow sensors comprise data transfer means, by means of which it is possible to send data to the
control 257, and the valve comprises data transfer means, by means of which it is possible to receive data from thecontrol 257. - The flow sensors are meant to observe a flow in the
pipes control 257 that it has observed the flow. If the sensor of thesensor part 255 which observes presence of water observes that no water is entering theoutlet 140 during a predetermined time, thecontrol 257 can deduce that theoutlet 140 grate is clogged and send a command to the valve to shut. - Additionally, the
system 400 can have a water tank in thepipe 491 for washing machine water. - A valve has been connected to the tank in the
pipe 491, which valve is equipped with data transfer means, by means of which it is possible to communicate with the flow sensors of thepipes control 257. When the flow sensors in thepipes washing machine 490 is taking in water and send information about it to the control of the tank valve or thecontrol 257, the valve control orcontrol 257 commands the valve to open, so that the tank is emptied into theoutlet 140. Thecontrol 257 commands the pump to pump water from the tank to thedevice 410. - The
system 400 can be integrated into different stages of process industry, for example cleaners, whereby water passing into thesewers 429 can first be treated in theoutlet 140 and thereafter be transferred into the sewer system of the cleaners to be utilized.
