This study assignment aims to clarify the effects of the project on groundwater and to develop optimal technical concept for groundwater. Since this is cultivation over large surface areas (about 27 ha on top of about 20 hectares of organically grown concentration in the immediate vicinity) of the water management at the cluster level will have to be properly arranged and have to be firmly built in for the onde PRUP and the subsequent environmental applications. For both the groundwater and the buffering of rainwater runoff. Therefore, a study is carried out internally (currently under way) around the water management at the cluster level, where both the storage, buffering, use, and infiltration of the rainwater and the groundwater extraction, and the effect is verified, on the surrounding area. The EIA plan drawn up for this project gives a first insight into the conditions. This internal study on water management at cluster level should result in an overall concept IWRM for the entire cluster with an associated organization. However, especially for the hatch groundwater missing information rather to support this study. The assignment detailed in this specification is intended to supplement the missing information on the groundwater situation on the ground and elaborated basic concept test on integrated water management feasibility.
