Llobregat河流域最重要的含水层位于下游，即Llobregat低含水层系统。自世纪后期以来，主要是在1950年代以后，地下水的密集开发极大地改变了其水文功能。由于盆地中心的钾矿开采区和海水入侵，以及农业、废物处理、砂和砾石坑渗漏和渗漏，地下水的盐度增加，水质受到影响。更严格的管理正在扭转和改善这种情况，从而保持LLAS作为巴塞罗那大都市区供水的关键因素的作用。除了基于模型的地下水数量管理和更严格的水质保护规则外，其他行动还包括人工补给和通过注入高度处理的再生废水来阻止海水入侵。建立了一个地下水用户社区，在实现可持续利用方面发挥了重要作用。
The most important aquifers of the Llobregat river basin are located in its lower part, namely the Low Llobregat Aquifer System (LLAS). Intensive groundwater development since the late nineteenth century and mostly after the 1950s has dramatically changed its hydrological functioning. Groundwater quality has suffered from salinity increase due to the potash mining area in the centre of the basin and seawater intrusion, as well as agriculture, waste disposal, sand and gravel pit backfilling and leakages. A stricter management is reversing and improving the situation and thus preserving the role of the LLAS as a crucial factor for the water supply to the Metropolitan Area of Barcelona. Besides model-based groundwater quantity management and stricter rules to protect water quality, additional actions include artificial recharge and installing a barrier to halt seawater intrusion by injecting highly treated reclaimed waste water. A groundwater user community was created and plays an important role in moving towards a sustainable use.
