Scope

Scope: The urban water environment comprehensive management proposed in this document aims to improve water quality, replenish ecological water, restore ecological systems, and enhance landscape quality. It includes the construction or transformation of all or part of the projects such as external pollution control, internal pollution treatment, water quality improvement, and ecosystem construction. This document is applicable to the urban (counties, cities, districts, and above) and their surrounding water environment comprehensive management, including water environment investigation and problem diagnosis, comprehensive management design, comprehensive management technology selection, construction management, investment cost estimation, and management effect evaluation, etc. Main technical content: The purpose of urban water environment investigation is to identify the factors of urban water environment ecological degradation and their impact intensity, and to provide basic information for urban water environment management. The scope of the investigation should be reasonably determined based on administrative divisions, water resource zoning, main functional zoning, ecological function zoning, water function zoning, ecological red line scope, water system connection scheduling areas, urban planning blue lines, and water surface rate, etc. In terms of time, it should reflect the historical evolution of urban water environment, and the water function zoning should comply with the relevant provisions of GB/T 50594. Urban water environment investigation work should be carried out through data collection and on-site investigation to obtain the basic situation of the natural and social environments of the engineering construction area and the surrounding affected areas. For areas with insufficient data, necessary on-site investigation and monitoring should be carried out using methods such as satellite remote sensing, drones, and geographic information systems.
