[0028] FIG. 1 is a perspective view with a cut away portion of the side of an embodiment of the invention,

[0029] FIG. 2 is an exploded view of the embodiment of the invention shown in FIG. 1,

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] In FIG. 1 it is shown a perspective view with a cut away portion of the side of an embodiment of the invention. An arrangement 100 for a sewerage system comprising a French drain according to the present invention comprises an inspection well device 102 suitable to be connected between a French drainage system and another drain system, such as a rainwater drain system, for enabling installation of said French drain at least partly under the another drain.

[0032] The inspection well device 102 comprises a bottom part 104, which is closed preventing unwanted water and dirties, such as rainwater from entering into the French drain, and a tube part 106 protruding from the bottom part 104. The top of the tube part 106 is open enabling inspection and purification of the French drain via the tube part 106.

[0033] The size and material of the inspection well device 102 can vary widely. The diameter of the inspection well device is preferably e.g. about 100 mm-600 mm, more preferably e.g. about 250 mm-280 mm to be compatible for commonly used pipelines. The height of the inspection well device is preferably e.g. about 10 mm-250 mm, more preferably e.g. about 15 mm-200 mm, but if required, the tube part can be in the same level with the bottom part having no height at all, or the tube part can be as high as required. The skilled person however knows that the height as well as the diameter of inspection well device can easily be selected to be what is needed.

[0034] In an embodiment, the tube part is selected to protruding so high in a rainwater drain inspection well 112 that rainwater is not able to flow into the French drain. Advantageously, the tube part 106, in the embodiment in question, reaches higher level than any outlets 114 for pipelines in the rainwater drain inspection well 112.

[0035] In another embodiment, the inspection well device 102 comprises closing means, such as an openable cap 108, for preventing unwanted water, such as rainwater, from entering into the French drain. The cap 108 as well as the corresponding top of the tube part can be threaded enabling easy opening and closing of the cap 108. In connection of the cap 108 can also be arranged suitable insulation. In the embodiment in question, the height of the tube part 106 is selected so, that when cap 108 is opened, rainwater from the rainwater drain does not flow in, being higher than the middle part of the highest outlet, for example.

[0036] Depending on embodiment, the inspection well device 102 can be connected to a rainwater drain, a rainwater drain inspection well and/or French drain inspection well. In one embodiment, the bottom part 104 comprises sleeves 110, which enables the connections of the inspection well device 102.

[0037] In one embodiment, the arrangement according to the present invention further comprises a rainwater drain inspection well 112. In the embodiment in question, the inspection well device 102 is arranged inside of the rainwater drain inspection well 112, so that the bottom part 104 and the tube part 106 are inside of the rainwater drain inspection well 112. The rainwater drain inspection well 112 is arranged to be formed to be continuing from the sleeves 110, or to be connected to the sleeves 110.

[0038] In the embodiment, wherein the inspection well device 102 according to the present invention is connected to a rainwater drain inspection well, the inspection well device 102 is arranged to be at least a partly inside to the rainwater drain inspection well. However, the sleeves 106 can also be arrange outside of the rainwater drain inspection well.

[0039] According to one embodiment, the rainwater drain inspection well 112 comprises a number of outlets 114 for rainwater pipelines. The number of outlets can vary, but preferably the number of the outlets is 1-4. However, more outlets can be formed to the rainwater drain inspection well 112 or the rainwater drain inspection well 112 can be formed without outlets. In an embodiment, the outlets 114 in the rainwater drain inspection well 112 are arranged in different heights. In this embodiment, the number of outlets can easily be higher than 4.

[0040] In an embodiment, the height of the inspection well device 102 inside of a rainwater drain inspection well 112 is selected so that the inspection well device 102, i.e. the tube part 106, inside the rainwater drain inspection well 112 is higher than the middle point of the a highest outlet.

[0041] In one embodiment, the arrangement according to the present invention further comprises a French drain inspection well 116 connectible to a French drain system.

[0042] The French drain inspection well 116 can be connected to the sleeves 110, for example, or arrange to be in connection with the inspection well device 102 and/or the rainwater drain inspection well 116 by some other means.

[0043] The scope of the invention is determined by the attached claims together with the equivalents thereof. The skilled persons will again appreciate the fact that the explicitly disclosed embodiments were constructed for illustrative purposes only, and the scope will cover further embodiments, embodiment combinations and equivalents that better suit each particular use case of the invention.
