Anthropogenic and industrial wastewater (IWW) could be an additional future source of water to support the needs of the people of the State of Qatar. New lagoons have been built using modern technologies to optimize water use and waste recycling, as well as increasing the green spaces around the country. To achieve successful development of these new lagoons, lessons should be learned from the old ponds by examining their biodiversity, ecology, and the roles played by aquatic plants and algae to remediate wastewaters at these ponds. The perspectives of using IWW (from oil and gas activities), that is currently pumped deep into the ground are presented. Instead of causing great damage to groundwater, IWW can be stored in artificial ponds prepared for ridding it of all impurities and pollutants of various types, organic and inorganic, thereby making it serviceable for various human uses. Phycoremediation, bioremediation, and phytoremediation methods adopted by algae, bacteria and aquatic native plants are discussed, and special attention should be paid to those that proved successful in removing heavy metals and degrading organic compounds. At least three native plants namely: , , and should be paid special attention, since these plants are efficient in remediation of arsenic and mercury; elements found abundantly in wastewater of gas activities. Some promising modern and innovative experiences and biotechnologies to develop efficient transgenic plants and microorganisms in removing and degrading pollutants are discussed, as an important strategy to keep the ecosystem clean and safe. Industrial wastewater (IWW) could be an alternative source of water at the Arabian Gulf region. Currently, IWW is pumped deep into the ground causing a great damage to groundwater; little information about this issue has been reported. Such IWW can be stored in artificial ponds designed for ridding them of all impurities of various types; various remediation methods can be used. Modern biotechnology to develop transgenic plants and microorganisms to enhance these remediation methods can be adopted.
人为和工业废水（IWW）可能成为支持卡塔尔国人民需求的未来水源之一。新的泻湖采用现代技术建造，旨在优化水的利用和废物回收，同时增加该国周围的绿地面积。为了成功开发这些新泻湖，应该从旧池塘吸取经验教训，研究其生物多样性、生态学以及水生植物和藻类在处理这些池塘废水中的作用。本文提出了利用（来自石油和天然气活动）目前被深泵入地下的 IWW 的观点。IWW 可以储存在为去除各种类型的杂质和污染物而准备的人工池塘中，而不是对地下水造成巨大破坏，这些污染物包括有机和无机的，从而使其可用于各种人类用途。本文讨论了藻类、细菌和水生本地植物采用的藻类修复、生物修复和植物修复方法，并特别关注那些已被证明在去除重金属和降解有机化合物方面成功的方法。至少有三种本地植物（、和）应该受到特别关注，因为这些植物在修复砷和汞方面非常有效；而这些元素在天然气活动废水中含量丰富。本文还讨论了一些有前途的现代创新经验和生物技术，以开发有效的转基因植物和微生物，用于去除和降解污染物，这是保持生态系统清洁和安全的重要策略。工业废水（IWW）可能成为阿拉伯海湾地区的替代水源。目前，IWW 被深泵入地下，对地下水造成了巨大破坏；但关于这个问题的信息很少。这种 IWW 可以储存在为去除各种类型的杂质而设计的人工池塘中；可以使用各种修复方法。可以采用现代生物技术来开发转基因植物和微生物，以增强这些修复方法。
