Introduction

Water withdrawal verification is the basis for the state to implement the water withdrawal permit system, implement planned water use management, and carry out water resource demonstrations. Water intake quota Standard is an important basis for approving the amount of water taken, and it is one of the main indicators for the country to assess the water resource utilization efficiency of industries and enterprises, and to evaluate the level of water saving of enterprises.

First, it is also an important means to implement the most stringent water resources management system.

GB/T 18916 will clarify the scope of water withdrawal, the scope of water withdrawal and the supply range of water withdrawal according to the characteristics of water use in different industrial industries.

Measurement, stipulates the calculation method of water intake quota, divides quota index levels, and makes requirements for quota management.
