Core Viewpoint - The construction of the South Ahmad City infrastructure project in Kuwait focuses on water management, addressing challenges related to groundwater, rainwater, and wastewater treatment [1][2][3]. Group 1: Groundwater Management - The project site has an average of 1-2 meters of groundwater, with seawater intrusion causing significant challenges during construction, including water levels reaching up to 2.5 meters [2]. - Six dewatering solutions were developed to manage groundwater levels, including surface recharge measures to maintain ecological balance and utilize excess water for construction needs [2][3]. Group 2: Rainwater Management - The project incorporates sponge city technology to collect and recycle rainwater, with plans to install approximately 76,009 rainwater collection units and over 264 kilometers of rainwater pipelines [3]. - The rainwater collection system is designed to support irrigation for green spaces, with a capacity to provide enough water for 50 acres of vegetation for a year after a single collection [3]. Group 3: Wastewater Management - The project will provide modern living conditions for at least 100,000 residents, integrating wastewater treatment and reuse into its design [3][4]. - Over 260 kilometers of wastewater pipelines will be installed, with a treatment capacity exceeding 50,000 cubic meters, allowing treated wastewater to be used for irrigation [3][4]. Group 4: Project Scale and Impact - The South Ahmad City infrastructure project covers an area of approximately 52.79 square kilometers and employs over 1,400 workers [4]. - The timely completion of the project is expected to alleviate housing pressure in the old Ahmad area, enhancing the living environment for local residents [4].

Group 1 - The State Intellectual Property Office of China has granted a patent for a "wastewater treatment system" to China National Offshore Oil Corporation Chemical Co., Ltd. and China National Offshore Oil Corporation Hegang Coal Chemical Co., Ltd. The patent was announced with the authorization number CN223087715U, and the application date was August 2024 [1] - The wastewater treatment system includes a sequence of connected units: a biochemical unit, a reclaimed water unit, and an advanced oxidation unit. The biochemical unit consists of multiple connected biochemical treatment pools [1] - The reclaimed water unit features a series of connected ultrafiltration membrane devices and reverse osmosis membrane devices. The outlet of the biochemical unit connects to the inlet of the ultrafiltration device, and the reverse osmosis product water connects to the circulating water system [1] Group 2 - China National Offshore Oil Corporation Chemical Co., Ltd. was established in 2000, with a registered capital of 461 million RMB. The company has invested in 18 enterprises and participated in 2,959 bidding projects, holding 206 patents and 12 trademark registrations [2] - China National Offshore Oil Corporation Hegang Coal Chemical Co., Ltd. was founded in 2006, with a registered capital of 233.56 million RMB. The company has invested in 1 enterprise and participated in 1,378 bidding projects, holding 38 patents and 6 trademark registrations [2]

Group 1 - The core viewpoint of the articles highlights that Tongchuan City has been recognized for its effective water environment governance practices, which have been promoted nationally by the Ministry of Ecology and Environment [1][2] - In 2024, Tongchuan City aims to enhance water quality through systematic and scientific approaches, achieving a continuous four-year compliance with Class III surface water standards at the Shichuan River monitoring point [1] - The city has implemented five key work mechanisms including regular scheduling, joint inspections, forecasting and early warning, on-site supervision, and inter-departmental collaboration to improve water ecological environment [1] Group 2 - Tongchuan City has constructed several water conservation projects, including the Danyang and Mudan Garden rainwater storage and ecological restoration projects, and new reservoirs to maximize natural rainfall retention [2] - The city has established a joint prevention and control mechanism for sudden water pollution incidents with neighboring districts, supported by a real-time water quality monitoring network consisting of 10 stations [2] - A total of 40 kilometers of recycled water pipelines have been built to alleviate water resource shortages, with the Peach Qu Po Reservoir regularly supplying ecological water downstream [2]
