Abstract：According to relevant management regulations,water resources demonstration is required for new projects that directly extract groundwater and require a water abstraction license.A new primary school project is planned for implementation in Wuqing District,Tianjin,covering an area of 17550 m²and involving a foundation pit with an excavation area of approximately 2 031 m².Based on the schemes for foundation pit support,water-stop measures,and groundwater dewatering and drainage,the demonstration level of this project was determined as Level II.Combining the engineering hydrological and geological conditions of the site,the rationality of drainage,water abstraction impacts,and return water impacts were analyzed.The resulting water resources demonstration conclusions provide a technical basis for water abstraction license approval authorities and water resources management departments.
