A modular water drainage device for relieving water-logged land underneath sealed and partially sealed surfaces, such as roads and buildings, is described. Vertical planks provide support to the water conduit as well as structural integrity to the module. The planks are connected to top and bottom pans, where the bottom pan serves as an impermeable trough-like structure for the collection of water. Wire screens fastened to the exterior of the module retain particulate outside the module. Openings in the top panel of the module allow a vacuum hose into the interior space between the vertical planks, for easy removal of accumulated silt. Modules can be arranged individually, connected linearly, in parallel, or perpendicular to each other. The present invention may also contain a system for controlling, recording and communicating the operation of a building ground water extraction device. This way, the building owner or operator is immediately and continuously informed about the ground water problem, if any, around or under the building. Also, if there is a ground water problem, there are accurate and up-to-date records about it. Therefore, proper remedial efforts may be planned and undertaken.
