To put it simply, the Regulations on the Prevention and Control of Pollution in Protected Areas of Drinking Water Sources make relevant provisions on pollution prevention and control in protected areas, and the specific division of water source protected areas is implemented in accordance with the Regulations on Water Source Protection issued by provinces, municipalities and autonomous regions.
I. Division of water source protection areas
Each province, municipality, and autonomous region has divided the surface water and groundwater source protection areas in its administrative area. For details of the scope of the division, please refer to the "Water Resources Protection Regulations" issued by the provincial administrative units. For example:
For drinking water source areas, part of the water areas and land areas shall be designated as drinking water source protection areas and drinking water source quasi-protection areas in accordance with the characteristics of different water areas and protection requirements. Drinking water source protection areas include primary protection areas and secondary protection areas. The drinking water source primary protection zone, secondary protection zone and quasi-protection zone shall not be less than the following areas:
(1) The main stream of the Yangtze River: the water area and land area within the range of 500 meters upstream to 500 meters downstream from the water intake, and 500 meters from the opposite bank to 100 meters outside the foot of the backwater slope embankment on the shore are the first-level protection areas; first-level protection Water areas and land areas within a range of 1,500 meters up and 500 meters down from the area are secondary protection areas;
Water and land areas within two kilometers and one kilometer down are quasi-protected areas.
(2) Other river channels: 1,000 meters upstream to 500 meters downstream of the water intake, and water and land areas within 100 meters outside the foot of the backslope on both sides of the bank are Class I protected areas; Water areas and land areas within a range of 500 meters and extensions of 500 meters are secondary protection areas; water areas and land areas within a range of two kilometers up to one kilometer and extensions of one kilometer outside the secondary protection areas are quasi-protection areas.
(3) Provincially managed lakes and large and medium-sized reservoirs: with the water intake as the center, a radius of 500 meters as the first-level protected area; outside the first-level protected area, the extension of one kilometer is the second-level protected area; outside the second-level protected area , The extension of one kilometer is the quasi-protected area.
(4) Small reservoirs: The entire water area is a first-level protected area, and the water collection area is a second-level protected area. In the "Water Resources Protection Regulations" of Beijing and Henan provinces, detailed geographical coordinates are given for drinking water sources within administrative divisions of this province and city.
2. Management regulations for drinking water source protection areas <br /> According to the regulations in the "Regulations for the Prevention and Control of Pollution in Drinking Water Source Protection Areas", drinking water source protection areas are generally divided into primary protection zones, secondary protection zones and quasi protection Area, each protected area has a clear geographical connection.
The drinking water surface water source protection area includes certain water areas and land areas.
Certain water areas and land areas near drinking water surface water intakes are designated as first-level protection zones for drinking-water surface water sources. The water quality of the first-level protection zones should meet Class II standards of the Environmental Quality Standards for Surface Water, and must comply with national regulations. The requirements of Sanitary Standards for Drinking Water. Designate certain water areas and land areas outside drinking water surface water source first-level protection areas as Class III standards for surface water environmental quality standards for drinking water surface water second-level protection areas, and ensure that the water quality of the first-level protection areas can meet the required standards. Certain water areas and land areas can be delineated outside the secondary protection area of drinking water surface water source as quasi-protection areas of drinking water surface water source according to needs. The water quality standards of quasi-protected areas should ensure that the water quality of the secondary protected areas can meet the prescribed standards.
The surface water source protection zones at all levels must comply with the following regulations:
I. All activities that undermine the ecological balance of the water environment and activities that damage water source forests, bank protection forests, and vegetation related to water source protection are prohibited.
2. It is forbidden to dump industrial waste residue, municipal waste, feces and other wastes into the waters.
3. Ships and vehicles transporting toxic and hazardous substances, oils and faeces are generally not allowed to enter the protected area. Those who must enter must apply in advance and be approved, registered and set up anti-seepage, spill-proof and leak-proof facilities by relevant departments.
4. The use of highly toxic and high-residue pesticides is prohibited. Chemical fertilizers must not be abused. Explosives or drugs must not be used to catch and kill fish.
The drinking water surface water source protection zones and quasi-protection zones must abide by the following regulations:
1. Primary protection zone
It is forbidden to build or expand construction projects unrelated to water supply facilities and water protection;
It is forbidden to discharge sewage into waters, and the sewage outlets already set must be removed;
No wharf irrelevant to the needs of water supply shall be set up, and the docking of ships is prohibited;
It is forbidden to stack and store industrial waste residue, municipal waste, feces and other wastes;
It is forbidden to set up oil depots;
It is forbidden to engage in the cultivation and stocking of poultry and livestock, and strictly control cage culture activities;
Tourism and other activities that may pollute water sources are prohibited.
2. Secondary protection zone
It is not allowed to build or expand construction projects that discharge pollutants into water bodies. Reconstruction projects must reduce pollutant emissions;
The original sewage outlet must reduce the amount of sewage discharged to ensure that the water quality in the protected area meets the prescribed water quality standards;
It is prohibited to set up docks for loading and unloading garbage, feces, oil and toxic substances.
3. Quasi-protected area
To discharge wastewater directly or indirectly into waters, it must meet the national and local regulations for wastewater discharge.
When the total discharge cannot guarantee that the water quality in the protected area meets the prescribed standards, the sewage load must be reduced.
