Alternatively, a water absorption pump with an electric motor without a power storage device can be used. In that case, the power may be taken from the existing cable in the buried pipe, or a dedicated cable for the water absorption pump may be wired in the buried pipe. In the latter case, it is necessary to add the dedicated cable when adding the buried pipe, but the work is much easier than the work such as adding the drainage hose.
