Circular No. 04/2020/TT-BTNMT Technical Regulations on Integrated Planning of Inter-Provincial River Basins and Inter-Provincial Water Resources.

This Circular No. 04/2020/TT-BTNMT sets technical requirements for preparing integrated planning for inter-provincial river basins and inter-provincial water sources. It outlines principles for planning—such as aligning with natural water conditions, socio-economic development, land use, and higher-level plans—and requires identifying urgent water issues, forecasting water availability, and setting objectives for managing exploitation, use, wastewater discharge, and disaster prevention.
The Circular also details procedures and data needed for drafting planning tasks and full basin plans, including assessing water resources, defining functional zoning of water bodies, allocating water among sectors, and identifying protection measures. It mandates mapping, monitoring systems, and solutions for droughts, floods, pollution, erosion, and groundwater depletion.
