    101520253035the outlet pipe and disconnection of the pump from the outletthe tube. However, the problem remains that when the submersible pumplifted for service, it is still covered by sewagethe content of the water.
    A long known problem, or desire, withinwastewater management is to minimize the residual volumewastewater that remains in the pump station tank when the pumpunable to transport more liquid away from the pumpthe station. By minimizing the residual volume, it is transported as suchas much as possible of the liquid and the solid material asis found in the wastewater away from the pumping station andfurther towards the treatment plant. If too much residual volume in the tankallowed, it causes large amounts of solid material to accumulatein the pump station which over time risks interfering orprevent proper operation of the pump station. A limitation oftoday's installations, however, are that the pump inlet mustbe at a minimum distance from the bottom of the tank forthat liquid and solid material should be undisturbed during normal operationbe able to enter the pump for further transport, and thismeans that the residual volume in the tank in today's installations issignificant and could not be minimized to the desired extent.

    The insert 15 comprises at least one in said container16 installed pump 19. The pump 19 comprises an inlet 20which is fluidly connected to a through hole 21 inthe shell of the container 16. Thus, the pump 19 is located on oneside of the shell of the container 16 and sucks liquid into the pump 19from the opposite side of the shell via the inlet 20 and thatthrough the hole 21 in the shell of the container 16. Preferably is101520253035the inlet 20 of the pump 19 is fluidly connected to a throughhole 21 in the wall 18 of the container 16,In the embodiment shown, the pump 19 is arranged horizontally,as shown in Figure 4. Ithoughother positions are conceivable, such as standing or leaning.
    According to an alternative embodiment, the inlet 20 of the pump 19 isfluid tight connection with two or more through holes inthe shell of the container 16.
    It should be mentioned that each insert 15 may includeone or more pumps 19, however, the insert 15 according tothe most preferred embodiment only a pump 19, and in itIn case an insert 15 comprises several pumps 19 each pump hasone inlet each fluid-tightly connected to onerespective through holes in the shell of the container. According to onealternative embodiment, where the insert 15 comprises severalpumps 19, are the inlets of two or more pumps 19fluidly connected by a common through hole inthe shell of the container. Preferably, the pump 19 is connected tothe shell of the container 16, the wall 18 in Figure 4, by beingscrewed to the inside of the shell of the container 16, preferablyby means of screws from the outside of the container 16.
    Furthermore, it is preferred that the pump 19 be dryinstalled in said container 16, i.e. that the pump 19 issurrounded by air / gas and includes an internal cooling system,and thus cooled during operation by means of the pumped liquid whichpasses through the pump 19. According to an alternative embodimentcan the insert 15 in the lower part of the container 16 shellinclude automatic one-way valve that drains the containerfrom any liquid, which has accumulated in the container, then the pump19 pumped out liquid and stopped. As an alternative to onedry installed pump, the container 16 may comprise acoolant surrounding the pump 19, which coolant is separatefrom the pumped liquid / wastewater. The coolant is cooled inin turn down via the shell 15 of the insert of the pumped liquid whichis in tank 2.
    Preferably, the insert 15 also comprises a control unit22 arranged in the container 16 and operatively connected to10152025303510the pump 19. The control unit 22 can, for example, be arranged onthe inside of the wall 18 of the container 16, and thus obtainindirect cooling from the liquid in the tank 2. In an alternativeembodiment, the pump station 1 comprises a central control unit(not shown) which is operatively connected to all pumps19 in the pump station 1. The insert 15 also includes in itthe embodiment shows an outlet pipe 23 which is connected topump 19 and which is releasably connected to the pump station1 outlet 7.

    It should be mentioned that in the embodiment shown is the control unit22 arranged on the outlet pipe 23 and thus receives belowoperation of the pump 19 cooling from the pumped liquid whichflows through the outlet pipe 23.
    In addition, the insert 15 to the tank 2 is secured toprevent the insert 15 from floating up or overturning when thewater is filled into tank 2. Preferably one is usedanchoring element 29 located between the insert 15 andtank 2, and in the embodiment shown surrounds the anchoringelement 29 the insert arrangement and rests on projections 30projecting radially from the wall 18 of the insert 15,the anchoring element 29 is suitably connected towall 2 of the tank 2. Thus, the anchoring shown is lowered.the element 29 down into the tank 2 after the insert arrangement. In aalternatively, not shown, design is the anchoring element29 set up in the tank 2 before the insert 15 is lowered into the tank2, whereupon the insert 15, when the same is placed on the seat 1010152025303512bottom surface 12, is suitably connected to the anchoring surfaceelement 29. In the embodiment shown, the anchoringthe element 29 up a footbridge 31, which is intended toused by service technicians during installation and service.
    It should be noted that in an alternative embodiment canthe anchoring element and the footbridge consist of one and the sameunit.
    Furthermore, the pump station 1 comprises at least one liquidlevel sensor (not shown) which is set to determinethe liquid level in the tank 2 in order to be able to control when the pump 19must be activated and / or deactivated. In the preferredthe embodiment comprises the insert 15 a pressure sensor (notshown) arranged in connection with the pump chamber 19 of the pump.
    The pressure sensor thus measures the liquid pressure in which the liquid istank 2 generates in pump 19. When liquid level in tank 2reaches a predetermined, or otherwise determined,position, the pump 19 is activated to pump out the sewagethe water. The pump 19 preferably stops when the liquid level inthe tank 2 is so low that the pump 19 sucks in air into the inlet20, ie sörplar. The remaining residual volume of liquid is inthis position is minimal and occupies only a part of the circularformed the chute 25. Alternatively, the pump 19 can then be stoppedthe fluid level is at a predetermined, or otherwisedetermined, position.
