Article 11 The drinking water source protection areas of lakes and reservoirs are generally defined according to the following scope:

(1) First-class protection areas: waters within a radius of 511 meters with the water intake as the center and beaches on one side of the water intake;

(2) secondary protected areas: waters within 2,511m outside the primary protected areas and beaches on the side of water intake points. Eleventh underground drinking water source protection areas are generally defined according to the following scope: with the water intake well as the center and the radius of 51 meters.

Fourteenth districts, cities and counties (cities, districts) people's governments shall determine the geographical boundaries of the designated drinking water source protection areas and set up signs.

It is forbidden for any unit or individual to change or damage the signs of protected areas without authorization. Fifteenth surface drinking water source protection zones in the water quality, applicable to the national "surface water environmental quality standards" class II standards; The water quality in the two protected areas shall be subject to Class III standard of the National Environmental Quality Standard for Surface Water.

the water quality in the underground drinking water source protection area shall be subject to the class ii standard of the national groundwater quality standard.

the water quality at the cross-section of major rivers across administrative areas is subject to the national Class III standard of Environmental Quality Standard for Surface Water. Chapter III Prevention and Control of Drinking Water Source Pollution Article 16 People's governments at or above the county level and relevant departments shall strengthen the vegetation protection of drinking water sources, take measures such as afforestation to conserve water sources, prevent soil erosion and improve the ecological environment.
